This sample is meant to demonstrate websockets with Apigee hybrid.

A sample websocket sample is included which responds with hello. To install the server,

• kubectl 1.13 or higher
• docker 19.x or higher
• skaffold 1.1.0 or higher (optional)

1. Build the docker image
2. Deploy to a container register
3. Modify the kubernetes manifest
4. Deploy the server kubectl apply -f websockets.yaml

This application can also be installed via skaffold. Modify the skaffold.yaml to set the appropriate project name.

skaffold run

When rerunning/installing the application, you may observe errors like this:

 - Error from server (Invalid): error when applying patch:
 ...
 ...
 `selector` does not match template `labels`

There is an open issue for this in the skaffold project.

Workaound: first run skaffold delete and then skaffold run

An API Proxy is included which verifies an API Key before allowing the websocket connection.

• Apigee hybrid runtime
• GKE 1.13.x
• apigeecli v1.1 (optional)
• A GCP Service Account with pemrissions to create apis, products ,developers and apps.

./install-sample-apigee.sh {org-name} {env-name} {path-to-service-account.json}

A sample websocket sample is included which takes an input from the user and sends it to the server.

• go 1.13 or higher
• goreleaser v0.120.3 (optional)

Option 1: Download the binary from releases Option 2: Build the binary manually using ./build.sh Option 3: Build using goreleaser goreleaser --snapshot --skip-publish --rm-dist NOTE: has been tested with v0.120.3

Input:

export API_KEY=xxx
export ENDPOINT=example.com
#use this flag to use ws:// vs. wss://  ; default is false
export TLS=false

./websocket-client
