So I switched over to using my colleagues Docker Enterprise demo cluster that is running in Azure. In this heterogeneous cluster are 1 Universal Control Plan (UCP) manager, 1 Docker Trusted Registry (DTR), 2 Windows workers, and 1 Linux worker.

In the first post in this series, SSL Options with Kubernetes – Part 1, we saw how to use the Kubernetes LoadBalancer service type to terminate SSL for your application deployed on a Kubernetes cluster in AWS. In this post, we will see how this can be done for a Kubernetes cluster in Azure.

In general, Kubernetes objects are portable across the various types of infrastructure underlying the cluster, i.e. public cloud, private cloud, virtualized, bare metal, etc. However, some objects are implemented through the Kubernetes concept of Cloud Providers. The LoadBalancer service type is one of these. AWS, Azure, and GCP (as well as vSphere, OpenStack and others) all implement a load balancer service using the existing load balancer(s) their cloud service provides. As such, each implementation is different. These differences are accounted for in the annotations to the Service object. For example, here is the specification we used for our service in the previous post.
