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. It specifies the project of the resource to operate on. It also specifies the project for API enablement check, quota, and billing. To specify a different project for quota and billing, use --billing-project or 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.
