[cloudrun] - custom audiences are being cleared on goblet deploys

[quajones]

custom audiences: https://cloud.google.com/run/docs/configuring/custom-audiences#setting

Setting custom audiences for Cloud Run is at the service level and applies to all serving revisions, similar to IAM authorization membership.

after setting custom audiences and describing the service you are able to see the proper annotation for the custom audiences being set
gcloud beta run services update service --add-custom-audiences=https://audience.com
gcloud run services describe service --format export

apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  annotations:
    run.googleapis.com/custom-audiences: '["https://audience.com”]’

once a cloud run service is redeployed this is no longer set and needs to be explicitly called out in the config.json cloudrun configurations

"cloudrun": {
    "launchStage": "BETA",
    "customAudiences": [ "https://audience.com" ]
}

as a potential solution determine if there are any custom audiences already defined for the service before deploy and pass them into the revision

[anovis]

would we need to switch the launch stage to beta as well if a custom audience is previously set?

[quajones]

@anovis yes the custom audiences are not generally available just yet

[anovis]

@quajones custom audiences are now GA as of November
