gcloud iam roles describe

NAME
gcloud iam roles describe - show metadata for a role
SYNOPSIS
gcloud iam roles describe ROLE_ID [--organization=ORGANIZATION     | --project=PROJECT_ID] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
This command shows metadata for a role.

This command can fail for the following reasons:

  • The role specified does not exist.
  • The active user does not have permission to access the given role.
EXAMPLES
To print metadata for the role spanner.databaseAdmin of the organization 1234567, run: 
gcloud iam roles describe roles/spanner.databaseAdmin --organization=1234567

To print metadata for the role spanner.databaseAdmin of the project myproject, run: 

gcloud iam roles describe roles/spanner.databaseAdmin --project=myproject

To print metadata for a predefined role, spanner.databaseAdmin, run: 

gcloud iam roles describe roles/spanner.databaseAdmin
POSITIONAL ARGUMENTS
ROLE_ID
ID of the role to describe. Curated roles example: roles/viewer. Custom roles example: CustomRole. For custom roles, you must also specify the --organization or --project flag.
FLAGS
At most one of these can be specified:
--organization=ORGANIZATION
Organization of the role you want to describe.
--project=PROJECT_ID
Project of the role you want to describe.

The Google Cloud project ID to use for this invocation. If omitted, then the current project is assumed; the current project can be listed using gcloud config list --format='text(core.project)' and can be set using gcloud config set project PROJECTID.

--project and its fallback core/project property play two roles in the invocation: they specify both the project of the resource to operate on, and the project for API enablement checks, quota, and billing. To specify a different project for quota and billing, use the --billing-project flag or the billing/quota_project property.

GCLOUD WIDE FLAGS
These flags are available to all commands: --access-token-file, --account, --billing-project, --configuration, --flags-file, --flatten, --format, --help, --impersonate-service-account, --log-http, --project, --quiet, --trace-token, --user-output-enabled, --verbosity.

Run $ gcloud help for details.
