gcloud alpha iam service-accounts get-iam-policy

NAME
gcloud alpha iam service-accounts get-iam-policy - get the IAM policy for a service account
SYNOPSIS
gcloud alpha iam service-accounts get-iam-policy SERVICE_ACCOUNT [--filter=EXPRESSION] [--limit=LIMIT] [--page-size=PAGE_SIZE] [--sort-by=[FIELD,…]] [GCLOUD_WIDE_FLAG]
DESCRIPTION
(ALPHA) This command gets the IAM policy for a service account. If formatted as JSON, the output can be edited and used as a policy file for set-iam-policy. The output includes an "etag" field identifying the version emitted and allowing detection of concurrent policy updates; see $ gcloud iam service-accounts set-iam-policy for additional details.

If the service account does not exist, this command returns a PERMISSION_DENIED error.

When managing IAM roles, you can treat a service account either as a resource or as an identity. This command is to get the iam policy of a service account resource. There are other gcloud commands to manage IAM policies for other types of resources. For example, to manage IAM policies on a project, use the $ gcloud projects commands.

EXAMPLES
To print the IAM policy for a given service account, run:
gcloud alpha iam service-accounts get-iam-policy my-iam-account@my-project.iam.gserviceaccount.com
POSITIONAL ARGUMENTS
SERVICE_ACCOUNT
The service account whose policy to get. The account should be formatted either as a numeric service account ID or as an email, like this: 123456789876543212345 or my-iam-account@somedomain.com.
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.
--page-size=PAGE_SIZE
Some services group resource list output into pages. This flag specifies the maximum number of resources per page. The default is determined by the service if it supports paging, otherwise it is unlimited (no paging). Paging may be applied before or after --filter and --limit depending on the service.
--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.

NOTES
This command is currently in alpha and might change without notice. If this command fails with API permission errors despite specifying the correct project, you might be trying to access an API with an invitation-only early access allowlist. These variants are also available:
