Google Container Registry access denied when pushing docker container

Question

I try to push my docker container to the google container registry, using this tutorial, but when I run

gcloud docker push b.gcr.io/my-bucket/image-name

I get the error :

The push refers to a repository [b.gcr.io/my-bucket/my-image] (len: 1)
Sending image list
Error: Status 403 trying to push repository my-bucket/my-image: "Access denied."

I couldn't find any more explanation (no -D, --debug, --verbose arguments were recognized), gcloud auth list and docker info tell me I'm connected to both services.

Anything I'm missing ?

Answer 1

You need to make sure the VM instance has enough access rights. You can set these at the time of creating the instance, or if you have already created the instance, you can also edit it (but first, you'll need to stop the instance). There are two ways to manage this access:

Option 1

Under the Identity and API access, select Allow full access to all Cloud APIs.

Option 2 (recommended)

Under the Identity and API access, select Set access for each API and then choose Read Write for Storage.

Note that you can also change these settings even after you have already created the instance. To do this, you'll first need to stop the instance, and then edit the configuration as mentioned above.
