usage_description="
|
|
Creates a GCP service account for GCloud SDK CLI to avoid having to re-login every day with 'gcloud auth login'
|
|
|
|
Grants this service account 'owner' rights to all projects
|
|
|
|
Creates and downloads a json credential and even prints the commands to activate the credential
|
|
|
|
export GOOGLE_CREDENTIALS=\"\$HOME/.gcloud/\$name-\$project-credential.json\"
|
|
gcloud auth activate-service-account --key-file=\"\$GOOGLE_CREDENTIALS\"
|
|
|
|
The following optional arguments can be given:
|
|
|
|
- service account name prefix (default: \$USER-cli)
|
|
- credential file path (default: \$HOME/.gcloud/\$name-\$project-credential.json)
|
|
- project (default: \$CLOUDSDK_CORE_PROJECT or gcloud config's currently configured project setting core.project)
|
|
|
|
This can also be used as a backup credential - this way if something accidentally happens to your primary user account
|
|
or this service account, you can always use the other to repair access without having to rely on colleagues who be away
|
|
|
|
Idempotent - safe to re-run, will skip service accounts and keyfiles that already exist
