如何找到 gcloud 上部署的分支（git hash）？

Question

I've been given a nodejs API server project that was deployed to gcloud, but I have no idea what "version" is deployed there. That is to say I need to determine if a specific git branch has been deployed to a specific environment.

The version in package.json was not regularly updated.

I tried this:

$ gcloud app versions describe 20220324t175829 --service default --project myproject

I got the version by listing the versions on gcloud and using the last deployed. I see hashes for each file deployed, but those aren't git commit hashes as far as I can tell.

Is there a way to determine this?

Answer 1

As @torek mentioned gcloud deployment need not be anything that was ever in a Git repository, and in general it will contain at least one thing that was never in Git. It therefore doesn't have a Git hash ID of its own. If the thing being deployed has a version-dump operation, use that; if that dumps a Git version, use that in turn to find the Git version. But otherwise there's no general solution.
