Answer 1

List all service accounts in a project

The following command lists all service accounts associated with a project:

$ gcloud iam service-accounts list

NAME                                    EMAIL
Compute Engine default service account  12345678-compute@developer.gserviceaccount.com
dummy-sa-1                              dummy-sa-1@MY_PROJECT.iam.gserviceaccount.com

List all Users and Service accounts in a project with their IAM roles

If you would like to list all users/service-accounts who have been granted any IAM roles on a specified project, you can use this command:

$ gcloud projects get-iam-policy MY_PROJECT

bindings:
- members:
  - serviceAccount:12345678-compute@developer.gserviceaccount.com
  - user:alice@foobar.com
  role: roles/editor
- members:
  - user:you@yourdomain.com
  - user:someoneelse@yourdomain.com
  role: roles/owner
etag: ARBITRARY_ETAG_HERE
version: 1

Formatting the output

gcloud supports formatting the output as json and lot of other customizations as needed, which might be easier to parse in certain cases or print only the information you need.

Examples:

# Prints the output as json instead of the default yaml format
$ gcloud projects get-iam-policy MY_PROJECT --format=json

# Display just the bindings in json format
$ gcloud projects get-iam-policy MY_PROJECT --format='json(bindings)'

# Display the bindings in a flattened format
$ $ gcloud projects get-iam-policy MY_PROJECT --format='flattened(bindings)'
