Specifies the identities requesting access for a Cloud Platform resource. members can have the following values:
allUsers : A special identifier that represents anyone who is on the internet; with or without a Google account.
allAuthenticatedUsers : A special identifier that represents anyone who is authenticated with a Google account or a service account.
user:{emailid} : An email address that represents a specific Google account. For example, alice@example.com .
serviceAccount:{emailid} : An email address that represents a service account. For example, my-other-app@appspot.gserviceaccount.com .
group:{emailid} : An email address that represents a Google group. For example, admins@example.com .
deleted:user:{emailid}?uid={uniqueid} : An email address (plus unique identifier) representing a user that has been recently deleted. For example, alice@example.com?uid=123456789012345678901 . If the user is recovered, this value reverts to user:{emailid} and the recovered user retains the role in the binding.
deleted:serviceAccount:{emailid}?uid={uniqueid} : An email address (plus unique identifier) representing a service account that has been recently deleted. For example, my-other-app@appspot.gserviceaccount.com?uid=123456789012345678901 . If the service account is undeleted, this value reverts to serviceAccount:{emailid} and the undeleted service account retains the role in the binding.
deleted:group:{emailid}?uid={uniqueid} : An email address (plus unique identifier) representing a Google group that has been recently deleted. For example, admins@example.com?uid=123456789012345678901 . If the group is recovered, this value reverts to group:{emailid} and the recovered group retains the role in the binding.
domain:{domain} : The G Suite domain (primary) that represents all the users of that domain. For example, google.com or example.com .

condition |
object (Expr )
The condition that is associated with this binding. If the condition evaluates to true , then this binding applies to the current request. If the condition evaluates to false , then this binding does not apply to the current request. However, a different role binding might grant the same role to one or more of the members in this binding. To learn which resources support conditions in their IAM policies, see the IAM documentation.

Expr
Represents a textual expression in the Common Expression Language (CEL) syntax. CEL is a C-like expression language. The syntax and semantics of CEL are documented at https://github.com/google/cel-spec.
Example (Comparison):
title: "Summary size limit"
description: "Determines if a summary is less than 100 chars"
expression: "document.summary.size() < 100"
Example (Equality):
title: "Requestor is owner"
description: "Determines if requestor is the document owner"
expression: "document.owner == request.auth.claims.email"
Example (Logic):
title: "Public documents"
description: "Determine whether the document should be publicly visible"
expression: "document.type != 'private' && document.type != 'internal'"
Example (Data Manipulation):
title: "Notification string"
description: "Create a notification string with a timestamp."
expression: "'New message received at ' + string(document.create_time)"
The exact variables and functions that may be referenced within an expression are determined by the service that evaluates it. See the service documentation for additional information.
