    Fields
    condition

    object ( Expr )

    A condition that determines whether this rule is used to evaluate the policy.

    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:

    • key_name : the namespaced name of the tag key, with the organization ID and a slash ( / ) as a prefix; for example, 123456789012/environment
    • 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

    For example: resource.matchTagId('tagKeys/123456789012', '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 .

    A custom, user-defined constraint. You can apply the constraint only to the resource types specified in the constraint, and only within the organization where the constraint is defined.
