Defines an Identity and Access Management (IAM) policy. It is used to specify access control policies for Cloud Platform resources.

A Policy consists of a list of bindings. A binding binds a list of members to a role, where the members can be user accounts, Google groups, Google domains, and service accounts. A role is a named list of permissions defined by IAM.

JSON Example

{
  "bindings": [
    {
      "role": "roles/owner",
      "members": [
        "user:[e-mail]",
        "group:[e-mail]",
        "domain:google.com",
        "serviceAccount:[e-mail]"
      ]
    },
    {
      "role": "roles/viewer",
      "members": ["user:[e-mail]"]
    }
  ]
}

YAML Example

bindings:
- members:
  - user:[e-mail]
  - group:[e-mail]
  - domain:google.com
  - serviceAccount:[e-mail]
  role: roles/owner
- members:
  - user:[e-mail]
  role: roles/viewer

For a description of IAM and its features, see the IAM developer's guide.

JSON representation
{ "version": number, "bindings": [ { object (Binding) } ], "auditConfigs": [ { object (AuditConfig) } ], "etag": string }

Fields
version	number Deprecated.
bindings[]	object (Binding) Associates a list of members to a role. bindings with no members will result in an error.
auditConfigs[]	object (AuditConfig) Specifies cloud audit logging configuration for this policy.
etag	string (bytes format) etag is used for optimistic concurrency control as a way to help prevent simultaneous updates of a policy from overwriting each other. It is strongly suggested that systems make use of the etag in the read-modify-write cycle to perform policy updates in order to avoid race conditions: An etag is returned in the response to getIamPolicy, and systems are expected to put that etag in the request to setIamPolicy to ensure that their change will be applied to the same version of the policy. If no etag is provided in the call to setIamPolicy, then the existing policy is overwritten blindly. A base64-encoded string.

AuditConfig

Specifies the audit configuration for a service. The configuration determines which permission types are logged, and what identities, if any, are exempted from logging. An AuditConfig must have one or more AuditLogConfigs.

If there are AuditConfigs for both allServices and a specific service, the union of the two AuditConfigs is used for that service: the log_types specified in each AuditConfig are enabled, and the exemptedMembers in each AuditLogConfig are exempted.

Example Policy with multiple AuditConfigs:

{
  "auditConfigs": [
    {
      "service": "allServices"
      "auditLogConfigs": [
        {
          "logType": "DATA_READ",
          "exemptedMembers": [
            "user:[e-mail]"
          ]
        },
        {
          "logType": "DATA_WRITE",
        },
        {
          "logType": "ADMIN_READ",
        }
      ]
    },
    {
      "service": "fooservice.googleapis.com"
      "auditLogConfigs": [
        {
          "logType": "DATA_READ",
        },
        {
          "logType": "DATA_WRITE",
          "exemptedMembers": [
            "user:[e-mail]"
          ]
        }
      ]
    }
  ]
}

For fooservice, this policy enables DATA_READ, DATA_WRITE and ADMIN_READ logging. It also exempts [e-mail] from DATA_READ logging, and [e-mail] from DATA_WRITE logging.

JSON representation
{ "service": string, "auditLogConfigs": [ { object (AuditLogConfig) } ] }

Fields
service	string Specifies a service that will be enabled for audit logging. For example, storage.googleapis.com, cloudsql.googleapis.com. allServices is a special value that covers all services.
auditLogConfigs[]	object (AuditLogConfig) The configuration for logging of each type of permission.

AuditLogConfig

Provides the configuration for logging a type of permissions. Example:

{
  "auditLogConfigs": [
    {
      "logType": "DATA_READ",
      "exemptedMembers": [
        "user:[e-mail]"
      ]
    },
    {
      "logType": "DATA_WRITE",
    }
  ]
}

This enables 'DATA_READ' and 'DATA_WRITE' logging, while exempting [e-mail] from DATA_READ logging.

JSON representation
{ "logType": enum (LogType), "exemptedMembers": [ string ] }

Fields
logType	enum (LogType) The log type that this config enables.
exemptedMembers[]	string Specifies the identities that do not cause logging for this type of permission. Follows the same format of Binding.members.

LogType

The list of valid permission types for which logging can be configured. Admin writes are always logged, and are not configurable.

Enums
LOG_TYPE_UNSPECIFIED	Default case. Should never be this.
ADMIN_READ	Admin reads. Example: CloudIAM getIamPolicy
DATA_WRITE	Data writes. Example: CloudSQL Users create
DATA_READ	Data reads. Example: CloudSQL Users list
