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.

When set, the google.type.Expr.expression field must contain 1 to 10 subexpressions, joined by the || or && operators. Each subexpression must use the resource.matchTag() or resource.matchTagId() Common Expression Language (CEL) function.

The resource.matchTag() function takes the following arguments:

  • value_name: the short name of the tag value

For example: resource.matchTag('123456789012/environment, 'prod')

The resource.matchTagId() function takes the following arguments:

  • key_id: the permanent ID of the tag key; for example, tagKeys/123456789012
  • value_id: the permanent ID of the tag value; for example, tagValues/567890123456

Union field kind. The type of rule that the PolicyRule defines. kind can be only one of the following:
values

object (StringValues)

The allowed and denied values for a list constraint. Valid only for list constraints.

allowAll

boolean

Whether to allow any value for a list constraint. Valid only for list constraints.

denyAll

boolean

Whether to deny all values for a list constraint. Valid only for list constraints.

enforce

boolean

Whether to enforce the constraint. Valid only for boolean constraints.

StringValues

The allowed and denied values for a list constraint.

For all constraints, these fields can contain literal values. Optionally, you can add the is: prefix to these values. If the value contains a colon (:), then the is: prefix is required.

Some constraints allow you to specify a portion of the resource hierarchy, known as a hierarchy subtree, that the constraint applies to. To specify a hierarchy subtree, use the under: prefix, followed by a value with one of these formats:

  • projects/{projectId} (for example, projects/tokyo-rain-123)
  • folders/{folder_id} (for example, folders/1234567890123)
  • organizations/{organization_id} (for example, organizations/123456789012)

A constraint's supportsUnder field indicates whether you can specify a hierarchy subtree. To learn which predefined constraints let you specify a hierarchy subtree, see the constraints reference.
