Traffic Director service security for GKE is now in General Availability. This provides the following:

  • Authentication and encryption using transport layer security (TLS) and mutual TLS (mTLS) for both Traffic Director with Envoy and proxyless gRPC applications. Server TLS policies and client TLS policies control whether services need to prove their identities to each other and use encrypted communication channels.

  • Authorization, based on characteristics of the client and the request. Authorization policies control whether a service is permitted to access another service, and which actions are allowed. Authorization is currently available only for Traffic Director with Envoy.

For more information, see the service security documentation and setup guides.

Fixed an issue where the Services user interface would display a warning if a service had a mix of healthy backend groups (x out of x healthy endpoints) and empty backend groups (0 out of 0 healthy endpoints). Now, services that have a mix of healthy backend groups and empty backend groups are shown as healthy.
