Looks like something was pushed, but at some point failing...

Answer 1

When you perform a docker push to Google Container Registry your image is stored inside a bucket in your project;

Container Registry uses Cloud Storage buckets as the underlying storage for container images. You control access to your images by granting permissions to the bucket for a registry.

If this is a first time that you try to push an image - the account you're using must have Storage Admin role. That's because a bucket that will store your images has to be created.

Have a look at the documentation that describes all the steps to grant necessary permissions.

If you're not familiar with GCP Cloud Storage then have a look at the guide describing how to use GCP's storage buckets.

Also you may consider trying out Artifact Registry which gives you more control over your images.
