• The documentation change made in https://github.com/GoogleCloudPlatform/cloud-sdk-docker/pull/481 added a claim of arm images
• 447.0.0 released shortly after does not have any arm images.

Current documentation retains this incorrect claim:

Arm support is only available in the docker images stored in the AR repo: gcr.io/google.com/cloudsdktool/google-cloud-cli

The images in docker-hub does not include the arm images. We have updated the docker-hub documentation accordingly: https://hub.docker.com/repository/docker/google/cloud-sdk/general

@anindyatahsin many of your links require Google SSO which normal people don't have...

Fwiw, here's what I see when I load https://console.cloud.google.com/artifacts/docker/google.com:cloudsdktool/us/gcr.io/google-cloud-cli/sha256:c7ca59159b0b71c72e9330afd6db7661febbf215718aeed0592120c80c0c0440;tab=manifest?invt=Abuw5Q:

... which does include linux/arm64

I don't understand why you wouldn't include arm64 images in the content you publish to Docker Hub...

If the repository on Docker Hub isn't maintained, it would make more sense to include something like:

Docker Hub content is not maintained

Instead of using docker pull google/cloud-sdk you should use docker pull gcr.io/google.com/cloudsdktool/google-cloud-cli:...
