The gce_vm_image_export tool exports a VM image, or a disk snapshot to Google Cloud Storage. It uses Daisy to perform exports while adding additional logic to perform export setup and clean-up, such as validating flags.

Download and install Go. Then pull and install the gce_vm_image_export tool, this should place the binary in the Go bin directory:

go get github.com/GoogleCloudPlatform/compute-image-import/cli_tools/gce_vm_image_export

• -destination_uri=DESTINATION_URI The Google Cloud Storage URI destination for the exported virtual disk file. For example: gs://my-bucket/my-exported-image.vmdk.

Exactly one of these must be specified:

• -source_image=SOURCE_IMAGE An existing Compute Engine image URI from which to export.
• -source_disk_snapshot=SOURCE_DISK_SNAPSHOT An existing Compute Engine disk snapshot URI from which to export.

• -client_id=CLIENT_ID Identifies the client of the importer. For example: gcloud or pantheon.
• -format=FORMAT Specify the format to export to, such as vmdk, vhdx, vpc, or qcow2.
• -project=PROJECT Project to run in, overrides what is set in workflow.
• -network=NETWORK Name of the network in your project to use for the image import. The network must have access to Google Cloud Storage. If not specified, the network named 'default' is used.
• -subnet=SUBNET Name of the subnetwork in your project to use for the image import. If the network resource is in legacy mode, do not provide this property. If the network is in auto subnet mode, providing the subnetwork is optional. If the network is in custom subnet mode, then this field should be specified. Region or zone should be specified if this field is specified.
• -zone=ZONE Zone of the image to import. The zone in which to do the work of importing the image. Overrides the default compute/zone property value for this command invocation.
• -timeout=TIMEOUT Maximum time a build can last before it is failed as "TIMEOUT". For example, specifying 2h will fail the process after 2 hours.
• -scratch_bucket_gcs_path=PATH GCS scratch bucket to use, overrides default set in Daisy.
• -oauth=OAUTH_PATH Path to oauth json file, overrides what is set in workflow.
• -compute_endpoint_override=ENDPOINT Compute API endpoint to override default.
• -disable_gcs_logging Do not stream logs to GCS
• -disable_cloud_logging Do not stream logs to Cloud Logging
• -disable_stdout_logging Do not display individual workflow logs on stdout
• -labels=[KEY=VALUE,...] labels: List of label KEY=VALUE pairs to add. Keys must start with a lowercase character and contain only hyphens (-), underscores (), lowercase characters, and numbers. Values must contain only hyphens (-), underscores (), lowercase characters, and numbers.
• -compute_service_account Compute service account to be used by exporter Virtual Machine. When empty, the Compute Engine default service account is used.
• -client_version Identifies the version of the client of the exporter
