Can't push image to google container registry - Caller does not have permission 'storage.buckets.get'

Question

I am working on a bitbucket pipeline for pushing image to gc container registry. I have created a service account with Storage Admin role. ([email protected])

gcloud auth activate-service-account --key-file key.json
gcloud config set project mgcp-xxxx
gcloud auth configure-docker --quiet
docker push eu.gcr.io/mgcp-xxxx/image-name

Although that the login is successful, i get: Token exchange failed for project 'mgcp-xxxx'. Caller does not have permission 'storage.buckets.get'. To configure permissions, follow instructions at: https://cloud.google.com/container-registry/docs/access-control

Can anyone advice on what i am missing?

Thanks!

Answer 1

For anyone reading all the way here. The other suggestions here did not help me, however I found that the Cloud Service Build Account role was also required. Then the storage.buckets.get dissappears.

This is my minimal role (2) setup to push docker images:

The Cloud Service Build Account role however adds many more permissions that simply storage.buckets.get. The exact permissions can be found here.

note: I am well aware the Cloud Service Build Account role also adds the storage.objects.get permission. However, adding roles/storage.objectViewerdid not resolve my problem. Regardless of the fact it had the storage.objects.get permission.

If the above does not work you might have the wrong account active. This can be resolved with:

gcloud auth activate-service-account --key-file key.json

If that does not work you might need to set the docker credential helpers with:

gcloud auth configure-docker --project <project_name>

On one final note. There seemed to be some delay between setting a role and it working via the gcloud tool. This was however minimal, think of a scope less than a minute.
