|
|
Quick list of unique project-level GCP IAM roles in use in the current GCP project or across all projects
|
|
|
|
Useful for quick lookups of IAM policy role names which are different from the human readable names in the GCP UI
|
|
|
|
eg. when backporting GCP IAM permissions to Terraform:
|
|
|
|
gcloud projects get-iam-policy \"\$(gcloud config list --format='get(core.project)')\" > /tmp/iam_policy.yaml
|
|
${0##*/} > /tmp/iam_roles_reference.txt
|
|
vim -O /tmp/iam_policy.yaml /tmp/iam_roles_reference.txt
|
|
# in another window edit the Terraform IAM and screen/tmux back and forth from this reference
|
|
|
|
|
|
NOTICE: does not include roles assigned to say individual GCS buckets, only those assigned at the project level to users, groups or serviceAccounts.
|
|
|
|
|
|
You can optionally specify the GCP project, otherwise infers your currently set core.project
|
|
|
|
If you specify 'all' for project, will return a sorted superset list from all projects
|
|
|
|
If the role you're looking for isn't currently in use, you may want to browse all role names in SDK format for use in Terraform via:
|
|
|
|
gcloud iam roles list --format='get(name)'
|
|
