Hi team,

I'm currently reviewing this pull request and will provide a full review shortly. In the meantime, here's a quick summary for you and other reviewers to get up to speed:

This pull request, "chore(cloudrun): migrate region tags for dockerfiles and yaml from run folder - part 2 - step 3", aims to migrate region tags in Dockerfiles and YAML files related to Cloud Run. It addresses internal issues b/347349975 and b/347349649. The changes are focused on removing redundant or obsolete region tags from the following files:

• run/pubsub/Dockerfile (Lines 16 and 44 removed)
• run/system-package/Dockerfile (Lines 23 and 27 removed)

The changes primarily involve removing commented-out lines related to region tags, streamlining the Dockerfiles. The author has confirmed that tests and lint checks have passed.

I'll have a more detailed review shortly, including a check for any potential side effects of these changes.

Joy fills the review.

This pull request removes region tags for the generic Cloud Run service. It correctly follows the sample guidelines and includes necessary updates to the README.

I noticed that the generic Cloud Run tag cloudrun_pubsub_dockerfile was removed. It's important to confirm that this tag is no longer needed and won't impact any documentation or other dependencies.

• run/pubsub/Dockerfile:16, tag cloudrun_pubsub_dockerfile

There is a possible violation for removing region tag in use.

• run/pubsub/Dockerfile:16, tag cloudrun_pubsub_dockerfile(usage: page 1 page 2).

I see the documents have been updated by cl/720655627 and confirmed of success in CP.

Checking source code for Page 1 and Page 2, the region has been updated:

As per discussion with our team, we need to fix the region tag cloudrun_pubsub_dockerfile for other languages and repos, to make the snippet-bot pass.

I'll retry this PR again when migration is finished for Node, Go and .NET.

Conflicting region tags for Go, Node and dotnet/csharp repos are fixed now. This PR is ready to be reviewed.
