I've been used since months or years to delete staging and artifacts buckets after gcloud app deploy command to save on billing costs. These temporary files rest in there forever and I get billed for it.
It always worked until this morning when I got this error:
ERROR: (gcloud.app.deploy) B instance [staging.my-proj-id.appspot.com] not found: The specified bucket does not exist.
I tried to recreate the bucket but I'm not allowed since I'm supposed to prove ownership of the staging.my-proj-id.appspot.com domain — which I have not.
AccessDeniedException: 403 You must verify site or domain ownership
I'm stuck and I have important changes to deploy
I fixed this running this command:
gcloud beta app repair
I got this direction trying to indicate my own staging bucket with
gcloud app deploy --bucket=gs://my-own-staging-bucket
like suggested in this answer which returned:
ERROR: (gcloud.app.deploy) Error Response: [5] Staging bucket staging.my-proj-id.appspot.com is not available. Please refer to https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps/repair to repair your app.
