gcloud spanner backups get-iam-policy - get the IAM policy for a Cloud Spanner backup
gcloud spanner backups get-iam-policy (BACKUP : --instance=INSTANCE) [--filter=EXPRESSION] [--limit=LIMIT] [--page-size=PAGE_SIZE] [--sort-by=[FIELD,...]] [GCLOUD_WIDE_FLAG ...]
gcloud spanner backups get-iam-policy displays the IAM policy associated with a Cloud Spanner database. 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.
To print the IAM policy for a given Cloud Spanner backup, run:
$ gcloud spanner backups get-iam-policy example-backup \ --instance=example-instance
- Backup resource - The Cloud Spanner backup for which to display the IAM policy.
The arguments in this group can be used to specify the attributes of this 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 backup on the command line with a fully specified name;
- —
set the property core/project;
- —
provide the argument --project on the command line.
This must be specified.
- BACKUP
ID of the backup or fully qualified identifier for the backup. To set the backup attribute:
provide the argument backup on the command line.
This positional argument must be specified if any of the other arguments in this group are specified.
- --instance=INSTANCE
The name of the Cloud Spanner instance.
To set the instance attribute:
provide the argument backup on the command line with a fully specified name;
provide the argument --instance on the command line;
set the property spanner/instance.
- --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.
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.
