put_file_system_policy#

EFS.Client.put_file_system_policy(**kwargs)#

Applies an Amazon EFS FileSystemPolicy to an Amazon EFS file system. A file system policy is an IAM resource-based policy and can contain multiple policy statements. A file system always has exactly one file system policy, which can be the default policy or an explicit policy set or updated using this API operation. EFS file system policies have a 20,000 character limit. When an explicit policy is set, it overrides the default policy. For more information about the default file system policy, see Default EFS file system policy.

Note

EFS file system policies have a 20,000 character limit.

This operation requires permissions for the elasticfilesystem:PutFileSystemPolicy action.

  • BypassPolicyLockoutSafetyCheck (boolean) – (Optional) A boolean that specifies whether or not to bypass the FileSystemPolicy lockout safety check. The lockout safety check determines whether the policy in the request will lock out, or prevent, the IAM principal that is making the request from making future PutFileSystemPolicy requests on this file system.

The default value is False.
