gcloud alpha compute backend-services list-usable

NAME: gcloud alpha compute backend-services list-usable - list usable backend services
SYNOPSIS: gcloud alpha compute backend-services list-usable [BACKEND_SERVICE_NAME] [--global | --region=REGION] [--filter=EXPRESSION] [--limit=LIMIT] [--page-size=PAGE_SIZE] [--sort-by=[FIELD,…]] [--uri] [GCLOUD_WIDE_FLAG …]
DESCRIPTION: (ALPHA) gcloud alpha compute backend-services list-usable retrieves the list of backend service resources in the specified project for which you have compute.backendService.get and compute.backendService.use permissions. This command is useful when you're creating load balancers in a Shared VPC environment and you want to use cross-project service referencing. You can use this command to find out which backend services in other projects are available to you for referencing.
EXAMPLES: To list all global backend services in a project, run:
gcloud alpha compute backend-services list-usable --global

To list all backend services in a region, run:
gcloud alpha compute backend-services list-usable --region=REGION
POSITIONAL ARGUMENTS: [BACKEND_SERVICE_NAME]

Name of the backend service to operate on.
FLAGS: At most one of these can be specified:

--global

If set, the backend service is global.

--region=REGION

Region of the backend service to operate on. Overrides the default compute/region property value for this command invocation.
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.

--uri

Print a list of resource URIs instead of the default output, and change the command output to a list of URIs. If this flag is used with --format, the formatting is applied on this URI list. To display URIs alongside other keys instead, use the uri() transform.
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:
