Thanks for writing back @dinvlad
I have to say I am very surprised google's own sdk is not good enough (atleast not yet).
Will explore terraform.

From almost 3 years ago The DM team is actively working on the GA type provier but we are facing minor issues with the API (because of the multi-region endpoints). This should be resolved soon.

The next time I meet with our google reps I'll have to ask them about the Deployment Manager road map because it really seems like its been abandoned. Its especially frustrating to not have support for cloud run because its serverless. serverless stuff is like the easiest use case for IaC but I have to roll my own janky scripts to deploy it- terraform isnt great for deploying apps

Yep, although it's possible to do Docker even in Terraform:
https://registry.terraform.io/providers/kreuzwerker/docker/latest/docs/resources/image#build
(but we're actually using https://github.com/GoogleContainerTools/kaniko for it via separate Cloud Build steps, which works nicely).
