Support for SSL between the load balancer and worker nodes in a Kubernetes cluster
- Services: Kubernetes Engine
- Release Date: June 28, 2023
When provisioning a load balancer for a Kubernetes service of type LoadBalancer, you can now specify that you want to implement SSL between the load balancer and the backend servers (worker nodes) in the backend set. This configuration is known as backend SSL. To implement backend SSL, you associate an SSL certificate with the load balancer's backend set.
Note that you can now implement full point-to-point SSL communication between clients and application pods running on worker nodes, since you could already create a load balancer with SSL termination at the listener.
For more information, see Implementing SSL/TLS between the Load Balancer and Worker Nodes.
