SSL Options with Kubernetes – Part 1

In this post (and future posts) we will continue to look into questions our clients have asked about using Docker Enterprise that have prompted us to do some further research and/or investigation. Here we are going to look into the options for enabling secure communications with our applications running under Kubernetes container orchestration on a Docker Enterprise cluster.

The LoadBalancer type of a service in Kubernetes is available if you are using one of the major public clouds, AWS, Azure or GCP, via their respective cloud provider implementations. An Ingress resource is available on any Kubernetes cluster including both on-premises and in the cloud. Both LoadBalancer and Ingress provide the capability to terminate SSL traffic. In this post will show how this is accomplished with an AWS LoadBalancer service.
