How can I specify a region for the Cloud Storage buckets used by Cloud Build for a Cloud Run deployment?

Question

When deploying a docker container image to Cloud Run, I can choose a region, which is fine. Cloud Run delegates the build to Cloud Build, which apparently creates two bucke

Looks like this is only possible by doing what you're mentioning in the comments:

1. Create a storage bucket in us-east1 as the source bucket ($SOURCE_BUCKET);
2. Create a Artifact Registry repo in us-east1;
3. Create the following cloudbuild.yaml:

   steps:
   - name: 'gcr.io/cloud-builders/docker'
     args: ['build', '-t', 'us-east1-docker.pkg.dev/$PROJECT_ID/my-repo/my-image', '.']
   images:
   - 'us-east1-docker.pkg.dev/$PROJECT_ID/my-repo/my-image'
   

4. Deploy with:

   $ gcloud builds submit --config cloudbuild.yaml --gcs-source-staging-dir=gs://$SOURCE_BUCKET/source

I think it should at least be possible to specify the Artifact Registry repo with the --tag option and have it be automatically created, but it currently rejects any domain that isn't gcr.io outright.
