This blog entry is the fourth in a series detailing how to run applications on Kubernetes, specifically using Couchbase as the Docker container, with previous parts covering different cloud providers. In this installment, the focus is on setting up a Kubernetes cluster on Azure, running a Docker container within it, exposing a pod as a service, and eventually shutting down the cluster. The process involves using Azure CLI for installation and management, configuring Azure-specific details like subscription and tenant IDs, and addressing challenges such as the lack of support for the LoadBalancer type at the time of writing. The guide concludes with instructions for shutting down the cluster and mentions some issues encountered, such as problems with the web UI and proxying, while noting that the LoadBalancer feature has since become available.
