gcloud iam roles list

NAME: gcloud iam roles list - list predefined roles, or the custom roles for an organization or project
SYNOPSIS: gcloud iam roles list [--show-deleted] [--organization=ORGANIZATION | --project=PROJECT_ID] [--filter=EXPRESSION] [--limit=LIMIT] [--sort-by=[FIELD,…]] [GCLOUD_WIDE_FLAG …]
DESCRIPTION: When an organization or project is specified, this command lists the custom roles that are defined for that organization or project.
Otherwise, this command lists IAM's predefined roles.
EXAMPLES: To list custom roles for the organization 12345, run:
gcloud iam roles list --organization=12345

To list custom roles for the project myproject, run:
gcloud iam roles list --project=myproject

To list all predefined roles, run:
gcloud iam roles list
FLAGS: --show-deleted

Show deleted roles by specifying this flag.

At most one of these can be specified:

--organization=ORGANIZATION

Organization of the role you want to list.

--project=PROJECT_ID

Project of the role you want to list.
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.
LIST COMMAND FLAGS: --filter=EXPRESSION

Apply a Boolean filter EXPRESSION to each resource item to be listed. If the expression evaluates True, then that item is listed. For more details and examples of filter expressions, run $ gcloud topic filters. This flag interacts with other flags that are applied in this order: --flatten, --sort-by, --filter, --limit.

--limit=LIMIT

Maximum number of resources to list. The default is unlimited. This flag interacts with other flags that are applied in this order: --flatten, --sort-by, --filter, --limit.

--sort-by=[FIELD,…]

Comma-separated list of resource field key names to sort by. The default order is ascending. Prefix a field with ``~´´ for descending order on that field. This flag interacts with other flags that are applied in this order: --flatten, --sort-by, --filter, --limit.
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.
