- gcloud preview compute backend-buckets test-iam-permissions - test IAM permissions for a Compute Engine backend bucket
- SYNOPSIS

gcloud preview compute backend-buckets test-iam-permissionsBACKEND_BUCKET--permissions=[PERMISSION,…] [--global|--region=REGION] [GCLOUD_WIDE_FLAG …]
-
- DESCRIPTION
-
(PREVIEW)gcloud preview compute backend-buckets test-iam-permissionstests the IAM permissions that a caller has on a Compute Engine backend bucket.Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may "fail open" without warning.
- EXAMPLES
-
To test if the caller has
compute.backendBuckets.getandcompute.backendBuckets.updatepermissions on a global backend bucketmy-backend-bucket, run:gcloud preview compute backend-buckets test-iam-permissions my-backend-bucket --permissions=compute.backendBuckets.get,compute.backendBuckets.updateTo test permissions on a regional backend bucket
my-backend-bucketin regionus-central1, run:gcloud preview compute backend-buckets test-iam-permissions my-backend-bucket --region=us-central1 --permissions=compute.regionBackendBuckets.get,compute.regionBackendBuckets.update - POSITIONAL ARGUMENTS
-
BACKEND_BUCKET-
ID of the backend bucket or fully qualified identifier for the backend bucket.
To set the backend_bucket attribute: + provide the argument backend_bucket on the command line.
- REQUIRED FLAGS
-
--permissions=[PERMISSION,…]- The set of permissions to check for the resource.
- OPTIONAL FLAGS
-
-
At most one of these can be specified:
--global- If set, the backend bucket is global.
--region=REGION-
Region of the backend bucket to test IAM permissions for. Overrides the default
compute/regionproperty value for this command invocation.
-
At most one of these can be specified:
- 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

- NOTES
-
This command is currently in DEVELOPER PREVIEW and may 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:
