OS Login

So you want to just ssh into the vm like you do everything else, you don't want to use

gcloud ssh login

or the "in browser" ssh client.

great , you want "OS Login"

lots of steps:

1. for the VM set the enable-oslogin meta data value to "TRUE"

in tf like this:

  metadata  = {
    enable-oslogin = "TRUE"
  }

2. give the user the correct roles:

Computer OS Login ( for vanilla , non-root access )
Compute OS Admin login ( for root access via sudo )

via command line this I think:

gcloud projects add-iam-policy-binding project-ID --member \
 serviceAccount:"velos-manager@project-ID.iam.gserviceaccount.com" \
 --role "roles/iam.serviceAccountUser"
 --no-user-output-enabled --quiet
