EXAMPLES: To set the IAM policy in POLICY-FILE on BUCKET:

gcloud alpha storage buckets set-iam-policy gs://b* POLICY-FILE
POSITIONAL ARGUMENTS: URLS [URLS …]

URLs for buckets to apply the IAM policy to. Can include wildcards.

POLICY_FILE

Path to a local JSON or YAML formatted file containing a valid policy.
The output of the get-iam-policy command is a valid file, as is any JSON or YAML file conforming to the structure of a Policy.
FLAGS: --continue-on-error, -c

If any operations are unsuccessful, the command will exit with a non-zero exit status after completing the remaining operations. This flag takes effect only in sequential execution mode (i.e. processor and thread count are set to 1). Parallelism is default.

--etag=ETAG, -e ETAG

Custom etag to set on IAM policy. API will reject etags that do not match this value, making it useful as a precondition during concurrent operations.
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. This variant is also available:
