This release focuses on a rework of the SDK pipeline. First of all, we have introduced new SDKs for all popular programming languages and published them on their respective package repositories:
The SDKs hosted in this repository (under ./sdk/...) have been completely removed. Please use only the SDKs from the above sources from now on as it will also remove several issues that were caused by the previous SDK pipeline.
Unfortunately, there were breaking changes introduced by the new SDK generation:
- Several structs and fields have been renamed in the Go SDK. However, nothing else changed so upgrading should be a matter of half an hour if you made extensive use of the SDK, or several minutes if just one or two methods are being used.
- All other SDKs changed to
openapi-generator
, which is a better maintained generator that creates better code than the one previously used. This manifests in TypeScript definitions for the NodeJS SDK and several other goodies. We do not have a proper migration path for those, unfortunately.
If you have issues with upgrading the SDK, please let us know in an issue on this repository!
Several indices have been added to the SQL Migrations. There are no backwards incompatible changes in this release but we advise to do a test-run of the SQL Migrations before applying them, as they might lock some tables which may cause downtimes.
Make a backup of your database before applying this change.
After applying these SQL Migrations, several queries and endpoints will be much faster than before.
A minor Schema change was introduced to the OAuth 2.0 Clients table. It is now possible to store arbitrary metadata for a client.
Make a backup of your database before applying this change.
This patch implements OpenID Connect Front-/Backchannel Logout 1.0
(read docs). Therefore, endpoint
/oauth2/auth/sessions/login/revoke
has been deprecated.
Please read all paragraphs of this section with the utmost care, before
executing hydra migrate sql
. Do not take this change lightly and create a
backup of the database before you begin. To be sure, copy the database and do a
dry-run locally.
Be aware that running these migrations might take some time when using large databases. Do a dry-run before hammering your production database.
hydra migrate sql
now shows an execution plan and asks for confirmation before
executing the migrations. To run migrations without user interaction, add flag
--yes
.
Orthogonal to the changes when accepting and rejection consent and login requests, the following endpoints have been updated as well:
DELETE /oauth2/auth/sessions/login/:subject
->DELETE /oauth2/auth/sessions/login?subject={subject}
GET /oauth2/auth/sessions/consent/:subject
->GET /oauth2/auth/sessions/login?subject={subject}
DELETE /oauth2/auth/sessions/consent/:subject
->DELETE /oauth2/auth/sessions/login?subject={subject}
DELETE /oauth2/auth/sessions/consent/:subject/:client
->DELETE /oauth2/auth/sessions/login?subject={subject}&client={client}
While this does not include a security warning, this patch allows developers to use slashes in dots in their subject/user IDs.
The Go SDK is now being generated using go-swagger
. The SDK generated using
swagger-codegen
is no longer supported. The old Go SDK is still available but
moved to a new path. To use it, change:
- import "github.com/ory/hydra/sdk/go/hydra"
- import "github.com/ory/hydra/sdk/go/hydra/swagger"
+ import hydra "github.com/ory/hydra-legacy-sdk"
+ import "github.com/ory/hydra-legacy-sdk/swagger"
Previously, login and consent requests were accepted/rejected by doing one of:
GET /oauth2/auth/requests/login/{challenge}
PUT /oauth2/auth/requests/login/{challenge}/accept
PUT /oauth2/auth/requests/login/{challenge}/reject
GET /oauth2/auth/requests/consent/{challenge}
PUT /oauth2/auth/requests/consent/{challenge}/accept
PUT /oauth2/auth/requests/consent/{challenge}/reject
We observed login/consent apps that did not properly sanitize the {challenge}
parameter, making it possible to escape the path by using ..
in the challenge
parameter (e.g. http://my-login-app/login?challenge=../../whatever
) causing
the login/consent app to execute a request it is not supposed to be making (e.g.
/oauth2/auth/requests/login/../../whatever/accept
).
From now on, the challenge has to be sent using a query parameter instead:
GET /oauth2/auth/requests/login?challenge={challenge}
PUT /oauth2/auth/requests/login/accept?challenge={challenge}
PUT /oauth2/auth/requests/login/reject?challenge={challenge}
GET /oauth2/auth/requests/consent?challenge={challenge}
PUT /oauth2/auth/requests/consent/accept?challenge={challenge}
PUT /oauth2/auth/requests/consent/reject?challenge={challenge}
Implementers will still need to make sure that challenge
is properly (query)
scaped, but it's generally easier to secure than a path parameter.
We've decided to make this a hard breaking change in order to force everybody to check if their application is vulnerable to this issue and to upgrade their code. The required code change is minimal but the resulting security improvements are potentially large.
This patch introduces changes to the way configuration works in ORY Hydra. It allows ORY Hydra to be configured from a variety of sources including environment variables and a configuration file. In the future, ORY Hydra might be configurable using etcd or consul. The changes allow ORY Hydra to reload configuration without restarting in the future.
An overview of configuration settings can be found here.
All changes are backwards compatible except for the way key rotation works (see next section) and the way DBAL plugins are loaded (see section after next).
Rotating system secrets was fairly cumbersome in the past and required a restart of ORY Hydra. This changed. The system secret is now an array where the first element is used for encryption and all elements can be used for decryption.
For more information on this topic, click here.
To make this change work, environment variable ROTATED_SYSTEM_SECRET
has been
removed and can no longer be used. Command hydra migrate secret
has also been
removed without replacement as it is no longer required for rotating secrets.
Environment variable DATABASE_PLUGIN
has been replaced by dsn
. To load a
plugin, set dsn: plugin:///path/to/plugin.so
.
Please note that internals have changed radically with this patch and that there is some refactoring effort required to make plugins work with the most recent version.
This patch requires you to run SQL migrations. No other important changes have been made.
This release ships with major scalability and reliability improvements and resolves several bugs.
Please read all paragraphs of this section with the utmost care, before
executing hydra migrate sql
. Do not take this change lightly and create a
backup of the database before you begin. To be sure, copy the database and do a
dry-run locally.
Be aware that running these migrations might take some time when using large databases. Do a dry-run before hammering your production database.
In order to keep data consistent across tables, several foreign key constraints have been added between consent, oauth2, client tables. If you are running a large database take enough time to run this migration - it might take a while depending on the amount of data and the database version and driver. Before executing this migration, you should manually check and remove inconsistent data.
This migration automatically removes inconsistent OAuth 2.0 and OpenID Connect data. Possible impacts are:
- Existing authorize codes, access, refresh tokens might be invalidated (all flows, including PKCE and OpenID Connect)
As OAuth 2.0 clients are generally capable of handling re-authorization, this should not have a serious impact. Removing this data increases security through strong consistency. The following data-altering statements will be executed:
-- First we need to delete all rows that point to a non-existing oauth2 client.
DELETE FROM hydra_oauth2_access WHERE NOT EXISTS (SELECT 1 FROM hydra_client WHERE hydra_oauth2_access.client_id = hydra_client.id);
DELETE FROM hydra_oauth2_refresh WHERE NOT EXISTS (SELECT 1 FROM hydra_client WHERE hydra_oauth2_refresh.client_id = hydra_client.id);
DELETE FROM hydra_oauth2_code WHERE NOT EXISTS (SELECT 1 FROM hydra_client WHERE hydra_oauth2_code.client_id = hydra_client.id);
DELETE FROM hydra_oauth2_oidc WHERE NOT EXISTS (SELECT 1 FROM hydra_client WHERE hydra_oauth2_oidc.client_id = hydra_client.id);
DELETE FROM hydra_oauth2_pkce WHERE NOT EXISTS (SELECT 1 FROM hydra_client WHERE hydra_oauth2_pkce.client_id = hydra_client.id);
-- request_id is a 40 varchar in the referenced table which is why we are resizing
-- 1. We must remove request_ids longer than 40 chars. This should never happen as we've never issued them longer than this
DELETE FROM hydra_oauth2_access WHERE LENGTH(request_id) > 40;
DELETE FROM hydra_oauth2_refresh WHERE LENGTH(request_id) > 40;
DELETE FROM hydra_oauth2_code WHERE LENGTH(request_id) > 40;
DELETE FROM hydra_oauth2_oidc WHERE LENGTH(request_id) > 40;
DELETE FROM hydra_oauth2_pkce WHERE LENGTH(request_id) > 40;
-- 2. Next we're actually resizing
ALTER TABLE hydra_oauth2_access ALTER COLUMN request_id TYPE varchar(40);
ALTER TABLE hydra_oauth2_refresh ALTER COLUMN request_id TYPE varchar(40);
ALTER TABLE hydra_oauth2_code ALTER COLUMN request_id TYPE varchar(40);
ALTER TABLE hydra_oauth2_oidc ALTER COLUMN request_id TYPE varchar(40);
ALTER TABLE hydra_oauth2_pkce ALTER COLUMN request_id TYPE varchar(40);
-- In preparation for creating the client_id index and foreign key, we must set it to varchar(255) which is also
-- the length of hydra_client.id
DELETE FROM hydra_oauth2_access WHERE LENGTH(client_id) > 255;
DELETE FROM hydra_oauth2_refresh WHERE LENGTH(client_id) > 255;
DELETE FROM hydra_oauth2_code WHERE LENGTH(client_id) > 255;
DELETE FROM hydra_oauth2_oidc WHERE LENGTH(client_id) > 255;
DELETE FROM hydra_oauth2_pkce WHERE LENGTH(client_id) > 255;
ALTER TABLE hydra_oauth2_access ALTER COLUMN client_id TYPE varchar(255);
ALTER TABLE hydra_oauth2_refresh ALTER COLUMN client_id TYPE varchar(255);
ALTER TABLE hydra_oauth2_code ALTER COLUMN client_id TYPE varchar(255);
ALTER TABLE hydra_oauth2_oidc ALTER COLUMN client_id TYPE varchar(255);
ALTER TABLE hydra_oauth2_pkce ALTER COLUMN client_id TYPE varchar(255);
This migration automatically removes inconsistent login & consent data. Possible impacts are:
- Users that set
remember
to true during login have to re-authenticate. - Users that set
remember
to true during consent have to re-authorize requested OAuth 2.0 Scope. - Data associated with OAuth 2.0 Clients that have been removed will be deleted.
That is achieved by running the following queries. Make sure you understand what
these queries do and what impact they may have on your system before executing
hydra migrate sql
:
-- This can be null when no previous login session exists, so let's remove default
ALTER TABLE hydra_oauth2_authentication_request ALTER COLUMN login_session_id DROP DEFAULT;
-- This can be null when no previous login session exists or if that session has been removed, so let's remove default
ALTER TABLE hydra_oauth2_consent_request ALTER COLUMN login_session_id DROP DEFAULT;
-- This can be null when the login_challenge was deleted (should not delete the consent itself)
ALTER TABLE hydra_oauth2_consent_request ALTER COLUMN login_challenge DROP DEFAULT;
-- Consent requests that point to an empty or invalid login request should set their login_challenge to NULL
UPDATE hydra_oauth2_consent_request SET login_challenge = NULL WHERE NOT EXISTS (
SELECT 1 FROM hydra_oauth2_authentication_request WHERE hydra_oauth2_consent_request.login_challenge = hydra_oauth2_authentication_request.challenge
);
-- Consent requests that point to an empty or invalid login session should set their login_session_id to NULL
UPDATE hydra_oauth2_consent_request SET login_session_id = NULL WHERE NOT EXISTS (
SELECT 1 FROM hydra_oauth2_authentication_session WHERE hydra_oauth2_consent_request.login_session_id = hydra_oauth2_authentication_session.id
);
-- Login requests that point to a login session that no longer exists (or was never set in the first place) should set that to NULL
UPDATE hydra_oauth2_authentication_request SET login_session_id = NULL WHERE NOT EXISTS (
SELECT 1 FROM hydra_oauth2_authentication_session WHERE hydra_oauth2_authentication_request.login_session_id = hydra_oauth2_authentication_session.id
);
-- Login, consent, obfuscated sessions that point to a client which no longer exists must be deleted
DELETE FROM hydra_oauth2_authentication_request WHERE NOT EXISTS (SELECT 1 FROM hydra_client WHERE hydra_oauth2_authentication_request.client_id = hydra_client.id);
DELETE FROM hydra_oauth2_consent_request WHERE NOT EXISTS (SELECT 1 FROM hydra_client WHERE hydra_oauth2_consent_request.client_id = hydra_client.id);
DELETE FROM hydra_oauth2_obfuscated_authentication_session WHERE NOT EXISTS (SELECT 1 FROM hydra_client WHERE hydra_oauth2_obfuscated_authentication_session.client_id = hydra_client.id);
-- Handled login and consent requests which point to a consent/login request that no longer exists must be deleted
DELETE FROM hydra_oauth2_consent_request_handled WHERE NOT EXISTS (SELECT 1 FROM hydra_oauth2_consent_request WHERE hydra_oauth2_consent_request_handled.challenge = hydra_oauth2_consent_request.challenge);
DELETE FROM hydra_oauth2_authentication_request_handled WHERE NOT EXISTS (SELECT 1 FROM hydra_oauth2_consent_request WHERE hydra_oauth2_authentication_request_handled.challenge = hydra_oauth2_consent_request.challenge);
Be aware that some queries might cascade and remove other data to. One such
example is checking hydra_oauth2_consent_request
for rows that have no
associated login_challenge
. If such a row is removed, the associated
hydra_oauth2_consent_request_handled
is removed as well.
Several indices have been added which should resolve table locking when searching in large data sets.
This patch adds the access token audience feature. For more information on this, head over to the docs.
Previously, the refresh grant did not check whether a client's allowed scope or audience changed. This has now been added. If an OAuth 2.0 Client performs the refresh flow but the requested token includes a scope which has not been whitelisted at the client, the flow will fail and no refresh token will be granted.
You can now set the login and consent flow timeout using environment variable
LOGIN_CONSENT_REQUEST_LIFESPAN
.
All refresh tokens issued with this release will expire after 30 days of
non-use. This behaviour can be modified using the REFRESH_TOKEN_LIFESPAN
environment variable. By setting REFRESH_TOKEN_LIFESPAN=-1
, refresh tokens are
set to never expire, which is the previous behaviour.
Tokens issued before this change will still be valid forever.
We discourage setting REFRESH_TOKEN_LIFESPAN=-1
as it might clog the database
with tokens that will never be used again. In high-scale systems,
REFRESH_TOKEN_LIFESPAN
should be set to something like 15 or 30 days.
To better represent the public and admin endpoint, previous swagger tags (like
oAuth2, jwks, ...) have been deprecated in favor of tags public
and admin
.
This has different impacts for the different code-generated client libraries.
If you use the hydra.SDK
interface only and the hydra.NewSDK()
factory,
everything will work as before. If you rely on e.g. hydra.Ne.OAuth2Api.)
, you
will be affected by this change.
All method signatures stayed the same, but the factory names for instantiating
the SDK client have changed. For example, hydra.Ne.OAuth2Api.)
is now
hydra.NewAdminApi()
and hydra.NewPublicApi()
- depending on which endpoints
you need to interact with.
Previously, extra fields coming from session.access_token
where directly
embedded in the OAuth 2.0 Access Token when the JSON Web Token strategy was
used. However, the token introspection response returned the extra data as a
field ext: {...}
.
In order to have a streamlined experience, session data is from now on stored in
a field ext: {...}
for Access Tokens formatted as JSON Web Tokens.
This change does not impact the opaque strategy, which is the default one.
Flags https-tls-key-path
and https-tls-cert-path
have been removed from the
hydra serve *
commands. Use environment variables HTTPS_TLS_CERT_PATH
and
HTTPS_TLS_KEY_PATH
instead.
Endpoint /health/status
, which redirected to /health/alive
was deprecated
and has been removed.
A new environment variable CORS_ENABLED
was introduced. It sets whether CORS
is enabled ("true") or not ("false")". Default is disabled.
This patch introduces some minor database schema changes. Before you apply it,
you must run hydra migrate sql
against your database.
Previously, all endpoints were exposed at one port. Since access control was removed with version 1.0.0, administrative endpoints (JWKs management, OAuth 2.0 Client Management, Login & Consent Management) were exposed and had to be secured with sophisticated set ups using, for example, an API gateway to control which endpoints can be accessed by whom.
This version introduces a new port (default :4445
, configurable using
environment variables ADMIN_PORT
and ADMIN_POST
) which is serves all
administrative APIs:
- All
/clients
endpoints. - All
/jwks
endpoints. - All
/health
,/metrics
,/version
endpoints. - All
/oauth2/auth/requests
endpoints. - Endpoint
/oauth2/introspect
. - Endpoint
/oauth2/flush
.
The second port exposes API endpoints generally available to the public (default
:4444
, configurable using environment variables PUBLIC_PORT
and
PUBLIC_HOST
):
./well-known/jwks.json
./well-known/openid-configuration
/oauth2/auth
/oauth2/token
/oauth2/revoke
/oauth2/fallbacks/consent
/oauth2/fallbacks/error
/userinfo
The simplest way to starting both ports is to run hydra serve
. This will start
a process which listens on both ports and exposes their respective features. All
settings (cors, database, tls, ...) will be shared by both listeners.
To configure each listener differently - for example setting CORS for public but
not privileged APIs - you can run hydra serve public
and hydra serve admin
with different settings. Be aware that this will not work with DATABASE=memory
and that both services must use the same secrets.
To reflect the changes made in this patch, the SDK's configuration struct has
been updated. Additionally, Configuration.PublicURL
has been added in case you
need to perform OAuth2 flows with the SDK before accessing the admin endpoints.
To reflect the changes of public and administrative ports, command hydra serve
is now hydra serve all
.
CLI Commands like hydra clients ...
, hydra keys ...
, hydra token flush
,
hydra token introspect
no longer use environment variable HYDRA_URL
as
default for --endpoint
but instead HYDRA_ADMIN_URL
.
Previously, OAuth 2.0 Token Introspection was protected with HTTP Basic Authorization (a valid OAuth 2.0 Client with Client ID and Client Secret was needed) or HTTP Bearer Authorization (a valid OAuth 2.0 Access Token was needed).
As OAuth 2.0 Token Introspection is generally an internal-facing endpoint used by resource servers to validate OAuth 2.0 Access Tokens, this endpoint has moved to the privileged port. The specification does not implore which authorization scheme must be used - it only shows that HTTP Basic/Bearer Authorization may be used. By exposing this endpoint to the privileged port a strong authorization scheme is implemented and no further authorization is needed. Thus, access control was stripped from this endpoint, making integration with other API gateways easier.
You may still choose to export this endpoint to the public internet and implement any access control mechanism you find appropriate.
Previously, OAuth 2.0 Clients had a flag called public
. If set to true, the
OAuth 2.0 Client was able to exchange authorize codes for access tokens without
a password. This is useful in scenarios where the device can not keep a secret
(browser app, mobile app).
Since OpenID Connect Dynamic Discovery was added, this flag collided with the
token_endpoint_auth_method
. If token_endpoint_auth_method
is set to none
,
then that is equal to setting public
to true
. To remove this ambiguity the
public
flag was removed.
If you wish to create a client that runs on an untrusted device (browser app,
mobile app), simply set "token_endpoint_auth_method": "none"
in the JSON
request.
If you are using the ORY Hydra CLI, you can use
--token-endpoint-auth-method none
to achieve what --is-public
did
previously.
The SQL migrations will automatically migrate clients that have public
set to
true
by setting token_endpoint_auth_method
to none
.
This patch resolves an issue which caused the migration to fail from beta.4 to
beta.5 / beta.6. The reason being that the keys stored in the data store had
mismatching kid
values if generated by <= beta.5. This patch runs a SQL
migration script which removes the old key and then, after booting up ORY Hydra,
regenerates it.
To apply this change, please run you must run hydra migrate sql
against your
database.
This patch implements the OpenID Connect Dynamic Client registration specification and thus now supports client authentication via JSON Web Tokens signed with RSA public/private keypairs, alongside HTTP Basic Authorization and sending the client's ID and secret in the POST body.
For more information on this, please refer to the specification.
Previously, when response types such as code token id_token
were requested
(OpenID Connect Hybrid Flow) it was enough for the client to have
response_types=["code", "token", "id_token"]
. This is however incompatible
with the OpenID Connect Dynamic Client Registration 1.0 spec which dictates that
the response_types
have to match exactly.
Assuming you are requesting &response_types=code+token+id_token
, your client
should have response_types=["code token id_token"]
, if other response types
are required (e.g. &response_types=code
, &response_types=token
) they too
must be included: response_types=["code", "token", "code token id_token"]
.
This will only affect you if you have clients requesting OpenID Connect Hybrid flows where more than one response_type is requested.
This patch introduces some minor database schema changes. Before you apply it,
you must run hydra migrate sql
against your database.
Previously, errors have been returned as nested objects:
{
"error": {
"error": "invalid_request"
// ...
}
}
while other endpoints, specifically those under OAuth 2.0 / OpenID Connect returned them without nesting:
{
"error": "invalid_request"
// ...
}
This patch updates all error responses and formats them coherently as across all APIs:
{
"error": "invalid_request"
// ...
}
With support for the OpenID Connect Dynamic Discovery specification, a new field
has been added to the OAuth 2.0 Client's metadata which is
token_endpoint_auth_method
. The token_endpoint_auth_method
specifies which
authentication methods the client can use at the token, introspection, and
revocation endpoint.
The default value for this method is client_secret_basic
which uses the Basic
HTTP Authorization scheme. If your client uses the POST body to perform
authentication, this value must be changed to client_secret_post
The
OpenID Connect Dynamic Client Registration 1.0
spec formulates that the client's ID should be sent as field client_id
. Until
now, the id was sent as field id
. This release changes that. For example, what
was previously
$ curl http://hydra/clients/my-client
{
"id": "my-client",
// ...
}
is now
$ curl http://hydra/clients/my-client
{
"client_id": "my-client",
// ...
}
For now, the id
field will still be returned, but is marked deprecated and
will be removed in future releases.
This section summarizes important changes introduced in 1.0.0. Follow it chronologically to ensure a proper migration.
We are very well aware that the changelist is huge and we try to prepare you as good as we can to migrate to this version. We also understand that breaking changes are frustrating and it takes time to adopt to them. We sincerely hope that the benefits from this version (improved consent flow, easier set up, clear boundaries & responsibilities) outweigh the hassle of upgrading to the new version.
If you have difficulties upgrading and would like a helping hand, reach out to us at mailto:[email protected] and we will help you with the upgrade process. Our services are billed by the hour and are priced fairly.
This is a (potentially incomplete) summary of what needs to be done to upgrade from versions of the 0.9.x branch, which are still common. As always, try this with a staging environment first and create back ups. Never run this directly in production unless you are 100% sure everything works:
- Get the latest ORY Hydra binary or docker image from the 1.0.0 branch.
- Run
$ export DATABASE_URL=<your-database-url>
. - If you want to keep using Access Control Policies and the Warden API, you
must install ORY Keto using the binaries or the docker image:
$ keto migrate hydra $DATABASE_URL
.$ keto migrate sql $DATABASE_URL
.- Read how to update the JWK storage:
AES-GCM nonce storage. If you only use
auto-generated keys and have never used POST or PUT on the
/keys
API, you can probably just execute aDELETE FROM hydra_jwk
to just remove all the auto-generated keys. When starting the ORY Hydra 1.0.0 CLI the required keys will be re-generated automatically. $ hydra migrate sql $DATABASE_URL
.
- If you don't use Access Control Policies nor the Warden API, you can skip ORY
Keto:
- Read how to update the JWK storage: AES-GCM nonce storage and read point 3.3 of this list.
$ hydra migrate sql $DATABASE_URL
.
$ export SCOPE_STRATEGY=DEPRECATED_HIERARCHICAL_SCOPE_STRATEGY
- this will set the scope strategy to the old scope strategy used in version 0.9.x. If you set this, you don't need to update the scopes your OAuth 2.0 Clients are allowed to request.$ hydra help serve
.$ hydra serve --your-flags
.
It's still a good idea to read through the changes in 0.10.0, for example:
Response payload changes to /warden/token/allowed
.
You can, however, skip the New consent flow subsection in
the 0.10.0 section. All required changes are explained in detail in this
release's consent flow description.
ORY Hydra is now OpenID Connect Certified! Certification spans the OAuth 2.0 Authorize Code Flow, Implicit Flow, and Hybrid Flow as well as dynamic discovery.
The certification is one reason for the breaking changes in the consent app.
One change has been made to the introspection API which is that key aud
is no
longer a string, but an array of strings. As this claim has not been supported
actively up until now, this will most likely not affect you at all.
Previously, we disabled the introspection of refresh tokens. This has now
changed to comply with the OAuth 2.0 specification. To distinguish tokens, use
the token_type
in the introspection response. It can either be access_token
or refresh_token
.
Internal access control, access control policies, and the Warden API have moved to a separate project called ORY Keto. You will be able to run a combination of ORY Hydra, ORY Oathkeeper, and ORY Keto which will be backwards compatible with ORY Hydra before the 1.0.0 release. This section explains how to upgrade and links to an example explaining the set up of the three services.
This means that ORY Hydra has no longer any type of internal access control.
Endpoints such as POST /clients
no longer require access tokens to be
accessed. You must secure these endpoints yourself. For more information,
click here.
ORY Keto handles access control using access control policies. The project currently supports the Warden API, Access Control Policy management, and Roles (previously known as Warden Groups). ORY Keto is independent from ORY Hydra as it does not rely on any proprietary APIs but instead uses open standards such as OAuth 2.0 Token Introspection and the OAuth 2.0 Client Credentials Grant to authenticate credentials. ORY Keto can be used as a standalone project, and might even be used with other OAuth 2.0 providers, opening up tons of possible use cases and scenarios. To learn more about the project, head over to github.com/ory/keto.
Assuming that you have the 1.0.0 release binary of ORY Hydra and ORY Keto locally installed, you can migrate the existing policies and Warden Groups using the migrate commands. Please back up your database before doing this:
$ export DATABASE_URL=<your-database-url>
# Migrate the policies and warden groups to keto
$ keto migrate hydra $DATABASE_URL
# Create other Keto database schemas
$ keto migrate sql $DATABASE_URL
# Run Hydra migrations
$ hydra migrate sql $DATABASE_URL
Now you can run keto serve
and endpoints /policies
as well as /warden
will
be available at ORY Keto's URL.
We have set up a docker-compose example of a set up that resembles ORY Hydra prior to this release. You can find the source and documentation at github.com/ory/examples.
If you find it difficult to run this set up but would like to use the old access control mechanisms, feel free to reach out to us at mailto:[email protected].
The Warden endpoints have moved to a new project. Thus, obviously, the URL changes too. The Warden API paths have changed as well:
/warden/allowed
is now/warden/subjects/authorize
/warden/token/allowed
is now/warden/oauth2/access-tokens/authorize
/warden/oauth2/clients/authorize
is a new endpoint that lets you authorize OAuth 2.0 Clients using their ID and secret.
The backwards compatible set up properly forwards the old paths. If you use that
image and you have been using http://my-hydra/warden/token/allowed
previously,
you can still use that URL to access that functionality if the
backwards-compatible image is hosted at that location. This image does, however,
currently not rewrite the request and response payloads. If you think that's a
good idea, let us know.
The request payload of these endpoints has changed:
/warden/token/allowed
- only keyscopes
was renamed toscope
in order to have a coherent API with any OAuth 2.0 endpoints which use thescope
for singular and plural:- Key
scopes
is nowscope
- a response body is{ "token": "...", "action": "...", "resource": "...", "scope": ["scope-a", "scope-b"] }
instead of (previously){ "token": "...", "action": "...", "resource": "...", "scopes": ["scope-a", "scope-b"] }
.
- Key
All other endpoints have not experienced any request payload changes.
The response payload of these endpoints has changed:
/warden/token/allowed
- keys have been changed to conform to the OAuth 2.0 Introspection response payload and offer a coherent API.- Key
grantedScopes
is nowscope
and is no longer an array string but rather a space-delimited string ("scope-a scope-b"). - Key
clientId
is nowclient_id
. - Key
issuedAt
is nowiat
. - Key
expires_at
is nowexp
. - Key
subject
is nowsub
. - Key
accessTokenExtra
is nowsession
and might be omitted if the OAuth 2.0 Introspection Endpoint does not provide session data. - Key
aud
("audience") has been added as a string array. - Key
iss
("issuer") has been added. - Key
nbf
("not before") has been added.
- Key
We are aware that these changes are rather serious, especially if you rely on the Warden API in each of your endpoints. If you have ideas on how to improve upgrading or offer a backwards compatible API, please open an issue and let us know.
All other endpoints have not experienced any response payload changes.
Warden Groups have been an experiment determined to simplify managing multiple
subjects with the same access rights. In ORY Keto, Warden Groups have been
renamed to Roles and the endpoint has moved from /warden/groups
to
/roles
. No request or response payloads have changed, only the URL is a
different one.
If you use the backwards-compatible image, you can access roles using the
/warden/groups
path as you did before.
Previously, JSON Web Keys did not have to specify a unique id. JWKs generated by
ORY Hydra typically only used public
or private
as KeyID. This patch changes
that and appends a unique id if no KeyID was given. To be able to separate
between public and private key pairs in resource name, the public/private
convention was kept.
This change targets specifically the OpenID Connect ID Token and HTTP TLS keys. The ID Token key was previously "hydra.openid.id-token:public" and "hydra.openid.id-token:private" which now changed to something like "hydra.openid.id-token:public:9a458aa3-65a0-4982-835f-343eec45183c" and "hydra.openid.id-token:private:fa353995-d77d-420a-b967-63bf0721271b" with the UUID part being random for every installation.
This change will help greatly with key rotation in the future.
If you rely on these keys in your applications and if they are hardcoded in some
way, you may want to use the /.well-known/openid-configuration
or
/.well-known/jwks.json
endpoints instead. Libraries, which handle these
standards appropriately, exist for almost any programming language.
These keys will be generated automatically if they do not exist yet in the database. No further steps for upgrading are required.
The consent flow has been refactored in order to implement session (login &
consent) management in ORY Hydra and in order to properly support OpenID Connect
parameters such as prompt
, max_age
, and others.
First, the consent flow has been renamed to "User Login and Consent Flow". The
consent app has been renamed to User Login Provider
and
User Consent Provider
. If you implement both features (explained in the next
sections) in one program, you can call it the User Login and Consent Provider
.
A reference implementation of the new User Login and Consent Provider is available at github.com/ory/hydra-login-consent-node.
The major difference between the old and new flow is, that authentication (user login) and scope authorization (user consent) are now two separate endpoints.
The new User Login and Consent Flow is documented in the developer guide.
The CLI has changed in order to improve developer experience and adopt to the changes made with this release.
The command hydra host
has been renamed to hydra serve
as projects ORY
Oathkeeper and ORY Keto use the serve
terminology as well.
Because this patch removes the internal access control, no root client and root
policy will be created upon start up. Thus, environment variable
FORCE_ROOT_CLIENT_CREDENTIALS
has been removed without replacement.
To better reflect what environment variables touch which system, ISSUER has been
renamed to OAUTH2_ISSUER_URL
and CONSENT_URL
has been renamed to
OAUTH2_CONSENT_URL
.
Additionally, flag --dangerous-force-auto-logon
has been removed it has no
effect any more.
The command hydra connect
has been removed as it no longer serves a purpose
now that the internal access control has been removed. Every command you call
now needs the environment variable HYDRA_URL
(previously named CLUSTER_URL
)
which should point to ORY Hydra's URL. Removing this command has an additional
benefit - privileged client IDs and secrets will no longer be stored in a
plaintext file on your system if you use this command.
As access control has been removed, most commands (except token user
,
token client
, token revoke
, token introspect
) work without supplying any
credentials at all. The listed exceptions support setting an OAuth 2.0 Client ID
and Client Secret using flags --client-id
and --client-secret
or environment
variables OAUTH2_CLIENT_ID
and OAUTH2_CLIENT_SECRET
.
All other commands, such as hydra clients create
, still support scenarios
where you would need an OAuth2 Access Token. In those cases, you can supply the
access token using flag --access-token
or environment variable
OAUTH2_ACCESS_TOKEN
. Assuming that you would like to automate management in a
protected scenario, you could do something like this:
$ token=$(hydra token client --client-id foo --client-secret bar --endpoint http://foobar)
$ hydra clients create --access-token $token ...
All commands now support the --endpoint
flag which sets the HYDRA_URL
in
case you don't want to use environment variables.
Flags --id
and --secret
are now called --client-id
and --client-secret
.
Flags --client-id
and --client-secret
have been added.
Flag --scopes
has been renamed to --scope
.
This command has been renamed to hydra token introspect
to properly reflect
that you are performing OAuth 2.0 Token Introspection.
Flags --client-id
and --client-secret
have been added.
Flag --scopes
has been renamed to --scope
.
As OAuth 2.0 specifies that terminology scope
does not have a plural scopes
,
we updated the places where the incorrect scopes
was used in order to provide
a more consistent developer experience.
This command renamed flag --allowed-scopes
to --scope
.
This command is a relict of an old version of ORY Hydra which is, according to our metrics, not being used any more.
This command has moved to Keto. All commands work the same way, but you have to
have Keto installed and replace hydra
with keto
. For example
hydra policies create ...
is now keto policies create ...
This command has moved to Keto. All commands work the same way, but you have to
have Keto installed and replace hydra groups
with keto roles
. For example
hydra groups create ...
is now keto roles create ...
As the SDK is code-generated, and we are not specialists in every language, we have only documented changes to the Go API. Please help improving this section by adding upgrade guides for the SDK you upgraded.
The following methods have been moved.
- The Access Control Policy SDK has moved to ORY Keto:
CreatePolicy(body swagger.Policy) (*swagger.Policy, *swagger.APIResponse, error)
is now available viagithub.com/ory/keto/sdk/go/keto

.
- The Warden Group SDK has moved to Keto:
AddMembersToGroup(id string, body swagger.GroupMembers) (*swagger.APIResponse, error)
is nowAddMembersToRole(id string, body swagger.RoleMembers) (*swagger.APIResponse, error)
and is now available viagithub.com/ory/keto/sdk/go/keto

is nowRemoveMembersFromRole(id string, body swagger.RoleMembers) (*swagger.APIResponse, error)
and is now available viagithub.com/ory/keto/sdk/go/keto
.
- The Warden API SDK has moved to Keto:
DoesWardenAllowAccessRequest(body swagger.WardenAccessRequest) (*swagger.WardenAccessRequestResponse, *swagger.APIResponse, error)
is nowIsSubjectAuthorized(body swagger.WardenSubjectAuthorizationRequest) (*swagger.WardenSubjectAuthorizationResponse, *swagger.APIResponse, error)
. Please check out the changes to the request/response body as well.DoesWardenAllowTokenAccessRequest(body swagger.WardenTokenAccessRequest) (*swagger.WardenTokenAccessRequestResponse, *swagger.APIResponse, error)
is nowIsOAuth2AccessTokenAuthorized(body swagger.WardenOAuth2AccessTokenAuthorizationRequest) (*swagger.WardenOAuth2AccessTokenAuthorizationResponse, *swagger.APIResponse, error)
. Please check out the changes to the request/response body as well.
- The Consent API SDK has been deprecated:
AcceptOAuth2ConsentRequest(id string, body swagger.ConsentRequestAcceptance) (*swagger.APIResponse, error)
has been removed without replacement.GetOAuth2ConsentRequest(id string) (*swagger.OAuth2ConsentRequest, *swagger.APIResponse, error)
has been removed without replacement.RejectOAuth2ConsentRequest(id string, body swagger.ConsentRequestRejection) (*swagger.APIResponse, error)
has been removed without replacement.
- The Login & Consent API SDK has been added:
AcceptConsentRequest(challenge string, body swagger.AcceptConsentRequest) (*swagger.CompletedRequest, *swagger.APIResponse, error)
AcceptLoginRequest(challenge string, body swagger.AcceptLoginRequest) (*swagger.CompletedRequest, *swagger.APIResponse, error)
RejectConsentRequest(challenge string, body swagger.RejectRequest) (*swagger.CompletedRequest, *swagger.APIResponse, error)
RejectLoginRequest(challenge string, body swagger.RejectRequest) (*swagger.CompletedRequest, *swagger.APIResponse, error)
GetLoginRequest(challenge string) (*swagger.LoginRequest, *swagger.APIResponse, error)
GetConsentRequest(challenge string) (*swagger.ConsentRequest, *swagger.APIResponse, error)
Additionally, the following methods have been removed as they were of very
little use and also mixed the Client Credentials flow with the Authorize Code
Flow which lead to weird usage. It's much easier to configure
clientcredentials.Config
or oauth2.Config
yourself.
GetOAuth2ClientConfig() (*clientcredentials.Config)
GetOAuth2Config() (*oauth2.Config)
The health check endpoint has moved from /health/status
to /health/alive
. We
set up a 308 redirect from /health/status
to /health/alive
so this should
not cause any issues.
The /health/alive
endpoint returns 200 OK
as soon as the HTTP server is
responsive. Another endpoint /health/ready
was added which returns 200 OK
only if the database connection is working as well.
As part of this change, function getInstanceStatus
of the SDK is now
isInstanceAlive
and isInstanceReady
.
Previously, if you had a typo in the JSON (e.g. client_nme
instead of
client_name
), ORY Hydra simply ignored that key. Now, an error is thrown if
unknown JSON keys are included.
ORY Hydra now uses UTC everywhere, reducing the possibility of errors stemming from different timezones.
Each endpoint that returns a list of items now supports pagination using limit
and offset
query parameters.
An endpoint (/oauth2/flush
) has been added that allows you to flush old access
tokens.
An endpoint /health/prometheus
for providing data to Prometheus has been
added.
This release resolves a security issue (reported by platform.sh) related to the fosite storage implementation in this project. Fosite used to pass all of the request body from both authorize and token endpoints to the storage adapters. As some of these values are needed in consecutive requests, the storage adapter of this project chose to drop all of the key/value pairs to the database in plaintext.
This implied that confidential parameters, such as the client_secret
which can
be passed in the request body since fosite version 0.15.0, were stored as
key/value pairs in plaintext in the database. While most client secrets are
generated programmatically (as opposed to set by the user) and most popular
OAuth2 providers choose to store the secret in plaintext for later retrieval, we
see it as a considerable security issue nonetheless.
The issue has been resolved by sanitizing the request body and only including
those values truly required by their respective handlers. This also implies that
typos (eg client_secet
) won't "leak" to the database.
There are no special upgrade paths required for this version.
This issue does not apply to you if you do not use an SQL backend. If you do
upgrade to this version, you need to run
hydra migrate sql path://to.your/database
.
If your users use POST body client authentication, it might be a good move to remove old data. There are multiple ways of doing that. Back up your data before you do this:
- Radical solution: Drop all rows from tables
hydra_oauth2_refresh
,hydra_oauth2_access
,hydra_oauth2_oidc
,hydra_oauth2_code
. This implies that all your users have to re-authorize. - Sensitive solution: Replace all values in column
form_data
in tableshydra_oauth2_refresh
,hydra_oauth2_access
with an empty string. This will keep all authorization sessions alive. Tableshydra_oauth2_oidc
andhydra_oauth2_code
do not contain sensitive information, unless your users accidentally sent the client_secret to the/oauth2/auth
endpoint.
We would like to thank platform.sh for sponsoring the development of a patch that resolves this issue.
The experimental endpoint /health/metrics
has been removed as it caused
various issues such as increased memory usage, and it was apparently not used at
all.
This release has a minor breaking change in the experimental Warden Group SDK:
FindGroupsByMember(member string) ([]swagger.Group, *swagger.APIResponse, error)
is now
ListGroups(member string, limit, offset int64) ([]swagger.Group, *swagger.APIResponse, error)
.
The change has to be applied in a similar fashion to other SDKs generated using
swagger.
Leave the member
parameter empty to list all groups, and add it to filter
groups by member id.
This release has several major improvements, and some breaking changes. It focuses on cryptographic security by leveraging best practices that emerged within the last one and a half years. Before upgrading to this version, make a back up of the JWK table in your SQL database.
This release requires running hydra migrate sql
before hydra host
.
The most important breaking changes are the SDK libraries, the new consent flow, the AES-GCM improvement, and the response payload changes to the warden.
We know that these are a lot of changes, but we highly recommend upgrading to this version. It will be the last before releasing 1.0.0.
The introspection endpoint was previously accessible to anyone with valid client credentials or a valid access token. According to spec, the introspection endpoint should be protected by additional access control mechanisms. This version introduces new access control requirements for this endpoint.
The client id of the basic authorization / subject of the bearer token must be
allowed action introspect
on resource rn:hydra:oauth2:tokens
. If an access
token is used for authorization, it needs to be granted the hydra.introspect
scope.
Previously, the consent flow looked roughly like this:
- App asks user for Authorization by generating the authorization URL (http://hydra.mydomain.com/oauth2/auth?client_id=...).
- Hydra asks browser of user for authentication by redirecting to the Consent App with a consent challenge (http://login.mydomain.com/login?challenge=xYt...).
- Retrieves a RSA 256 public key from Hydra.
- Uses said public key to verify the consent challenge.
- User logs in and authorizes the requested scopes
- Consent app generates the consent response
- Retrieves a private key from Hydra which is used to sign the consent response.
- Creates a response message and sign with said private key.
- Redirects the browser back to Hydra, appending the consent response (http://hydra.mydomain.com/oauth2/auth?client_id=...&consent=zxI...).
- Hydra validates consent response and generates access tokens, authorize codes, refresh tokens, and id tokens.
This approach had several disadvantages:
- Validating and generating the JSON Web Tokens (JWTs) requires libraries for each language
- Because libraries are required, auto generating SDKs from the swagger spec is impossible. Thus, every language requires a maintained SDK which significantly increases our workload.
- There have been at least two major bugs affecting almost all JWT libraries for any language. The spec has been criticised for it's mushy language.
- The private key used by the consent app for signing consent responses was originally thought to be stored at the consent app, not in Hydra. However, since Hydra offers JWK storage, it was decided to use the Hydra JWK store per default for retrieval of the private key to improve developer experience. However, to make really sense, the private key should have been stored at the consent app, not in Hydra.
- Private/Public keypairs need to be fetched on every request or cached in a way that allows for key rotation, complicating the consent app.
- There is currently no good mechanism for rotating JWKs in Hydra's storage.
- The consent challenge / response has a limited length as it's transmitted via the URL query. The length of a URL is limited.
Due to these reasons we decided to refactor the consent flow. Instead of relying on JWTs using RSA256, a simple HTTP call is now enough to confirm a consent request:
- App asks user for Authorization by generating the authorization URL (http://hydra.mydomain.com/oauth2/auth?client_id=...).
- Hydra asks browser of user for authentication by redirecting to the Consent App with a unique consent request id (http://login.mydomain.com/login?consent=fjad2312).
- Consent app makes a HTTP REST request to
http://hydra.mydomain.com/oauth2/consent/requests/fjad2312
and retrieves information on the authorization request. - User logs in and authorizes the requested scopes
- Consent app accepts or denies the consent request by making a HTTP REST
request to
http://hydra.mydomain.com/oauth2/consent/requests/fjad2312/accept
orhttp://hydra.mydomain.com/oauth2/consent/requests/fjad2312/reject
. - Redirects the browser back to Hydra.
- Hydra validates consent request by checking if it was accepted and generates access tokens, authorize codes, refresh tokens, and id tokens.
Learn more on how the new consent flow works in the guide: https://ory.gitbooks.io/hydra/content/oauth2.html#consent-flow
Previously, the audience terminology was used as a synonym for OAuth2 client
IDs. This is no longer the case. The audience is typically a URL identifying the
endpoint(s) the token is intended for. For example, if a client requires access
to endpoint http://mydomain.com/users
, then the audience would be
http://mydomain.com/users
.
This changes the payload of /warden/token/allowed
and is incorporated in the
new consent flow as well. Please note that it is currently not possible to set
the audience of a token. This feature is tracked with
here.
IMPORTANT NOTE: In OpenID Connect ID Tokens, the token is issued for that
client. Thus, the aud
claim must equal to the client_id
that initiated the
request.
Previously, the response of the warden endpoint contained shorthands like aud
,
iss
, and so on. Those have now been changed to their full names:
sub
is now namedsubject
.scopes
is now namedgrantedScopes
.iss
is now namedissuer
.aud
is now namedclientId
.iat
is now namedissuedAt
.exp
is now namedexpiresAt
.ext
is now namedaccessTokenExtra
.
The Go SDK was completely replaced in favor of a SDK based on swagger-codegen
.
Unfortunately this means that any code relying on the old SDK has to be
replaced. On the bright side the dependency tree is much smaller as no direct
dependencies to ORY Hydra's code base exist any more.
Read more on it here: https://ory.gitbooks.io/hydra/content/sdk/go.html
GET /health
is nowGET /health/status
GET /health/stats
is nowGET /health/metrics
GET /warden/groups
now returns a list of groups, not just a list of strings
(group ids).
The previous scope matching strategy has been replaced in favor of a
wildcard-based matching strategy. Previously, foo
matched foo
and foo.bar
and foo.baz
. This is no longer the case. So foo
matches only foo
. Matching
subsets is possible using wildcards. foo.*
matches foo.bar
and foo.baz
.
This change makes setting scopes more explicit and is more secure, as it is less likely to make mistakes.
Read more on this strategy here.
To fall back to hierarchical scope matching, set the environment variable
SCOPE_STRATEGY=DEPRECATED_HIERARCHICAL_SCOPE_STRATEGY
. This feature might be
fully removed in a later version.
Our use of crypto/aes
's AES-GCM was replaced in favor of
cryptopasta/encrypt
.
As this includes a change of how nonces are appended to the ciphertext, ORY
Hydra will be unable to decipher existing databases.
There are two paths to migrate this change:
- If you have not added any keys to the JWK store:
- Stop all Hydra instances.
- Drop all rows from the
hydra_jwk
table. - Start one Hydra instance and wait for it to boot.
- Restart all remaining Hydra instances.
- If you added keys to the JWK store:
- If you can afford to re-generate those keys:
- Write down all key ids you generated.
- Stop all Hydra instances.
- Drop all rows from the
hydra_jwk
table. - Start one Hydra instance and wait for it to boot.
- Restart all remaining Hydra instances.
- Regenerate the keys and use the key ids you wrote down.
- If you can not afford to re-generate the keys:
- Export said keys using the REST API.
- Stop all Hydra instances.
- Drop all rows from the
hydra_jwk
table. - Start one Hydra instance and wait for it to boot.
- Restart all remaining Hydra instances.
- Import said keys using the REST API.
- If you can afford to re-generate those keys:
The signature algorithm used to generate authorize codes, access tokens, and refresh tokens has been upgraded from HMAC-SHA256 to HMAC-SHA512. With upgrading to alpha.9, all previously issued authorize codes, access tokens, and refresh will thus be rendered invalid. Apart from some re-authorization procedures, which are usually automated, this should not have any significant impact on your installation.
The HS256 (symmetric/shared keys) JWK Generator now uses the full 256 bit range to generate secrets instead of a predefined rune sequence. This change only affects keys generated in the future.
The JWK algorithm ES521
was renamed to ES512
. If you want to generate a key
using this algorithm, you have to use the update name in the future.
This release removes build tags -http
, -automigrate
, -without-telemetry
from the docker hub repository and replaces it with a new and tiny (~6MB) docker
image containing the binary only. Please note that this docker image does not
have a shell, which makes it harder to penetrate.
Instead of relying on tags to pass arguments, it is now possible to pass command
arguments such as docker run oryd/hydra:v0.10.0 host --dangerous-force-http
directly.
Version 0.10.8 reintroduces an image with a shell, appended with tag
-alpine
.
It is now possible to alter resource name prefixes (rn:hydra
) using the
RESOURCE_NAME_PREFIX
environment variable.
- It is now possible to refresh openid connect tokens using the refresh_token
grant. An ID Token is issued if the scope
openid
was requested, and the client is allowed to receive an ID Token.
To improve ORY Hydra and understand how the software is used, optional, anonymized telemetry data is shared with ORY. A change was made to help us understand which telemetry sources belong to the same installation by hashing (SHA256) two environment variables which make up a unique identifier. Click here to read more about how we collect telemetry data, why we do it, and how to enable or disable it.
This release adds the possibility to specify special characters in the
FORCE_ROOT_CLIENT_CREDENTIALS
by www-url-decoding
the values. If you have
characters that are not url safe in your root client credentials, please use the
following form to specify them:
"FORCE_ROOT_CLIENT_CREDENTIALS=urlencode(id):urlencode(secret)"
.
This version adds performance metrics to /health
and sends anonymous usage
statistics to our servers, click here
for more details on this feature and how to disable it.
This PR improves some performance bottlenecks, offers more control over Hydra, moves to Go 1.8, and moves the REST documentation to swagger.
Before applying this update, please make a back up of your database. Do not upgrade directly from versions below 0.7.0.
To upgrade the database schemas, please run the following commands in exactly this order
$ hydra help migrate sql
$ hydra help migrate ladon
$ hydra migrate sql mysql://...
$ hydra migrate ladon 0.6.0 mysql://...
Ladon was greatly improved with version 0.6.0, resolving various performance bottlenecks. Please read more on this release here.
Redis and RethinkDB are removed from the repository now and no longer supported, see this issue.
To reflect the GitHub organization rename, Hydra was moved from
https://github.com/ory-am/hydra
to https://github.com/ory/hydra
.
The method FindPoliciesForSubject
of the policy SDK was removed. Instead,
List
was added. The HTTP endpoint GET /policies
no longer allows to query by
subject.
To generate JWKs previously the payload at POST /keys
was
{ "alg": "...", "id": "some-id" }
. id
was changed to kid
so this is now
{ "alg": "...", "kid": "some-id" }
.
SQL Migrations are no longer automatically applied. Instead you need to run
hydra migrate sql
after upgrading to a Hydra version that includes a breaking
schema change.
Set the log format to json using export LOG_FORMAT=json
You can configure SQL connection limits by appending parameters max_conns
,
max_idle_conns
, or max_conn_lifetime
