NAME
    gcloud alpha pubsub topics get-iam-policy - get the IAM policy for a topic

SYNOPSIS
    gcloud alpha pubsub topics get-iam-policy TOPIC [--filter=EXPRESSION]
        [--limit=LIMIT] [--page-size=PAGE_SIZE] [--sort-by=[FIELD,...]]
        [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    (ALPHA) gcloud alpha pubsub topics get-iam-policy displays the IAM policy
    associated with a topic. 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 $ {parent} set-iam-policy for additional details.

EXAMPLES
    To print the IAM policy for a given topic, run:

        $ gcloud alpha pubsub topics get-iam-policy my-topic

POSITIONAL ARGUMENTS
     Topic resource - The topic for which to display the IAM policy. This
     represents a Cloud resource. (NOTE) Some attributes are not given
     arguments in this group but can be set in other ways.

     To set the project attribute:
      ◆ provide the argument topic on the command line with a fully specified
        name;
      ◆ provide the argument --project on the command line;
      ◆ set the property core/project.

     This must be specified.

       TOPIC
          ID of the topic or fully qualified identifier for the topic.

          To set the topic attribute:
          ▸ provide the argument topic on the command line.

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.
