Policy : An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources. A
Policy is a collection of
bindings. A
binding binds one or more
members to a single
role. Members can be user accounts, service accounts, Google groups, and domains (such as G Suite). A
role is a named list of permissions; each
role can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a
binding can also specify a
condition, which is a logical expression that allows access to a resource only if the expression evaluates to
true. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the
IAM documentation.
