kubernetes

Kubernetes is a colossal beast. You need to understand many different concepts before it starts being useful. When everything is set up, you’ll probably want to expose some pods to the outside of the cluster. Kubernetes provides different ways to do it: I’ll describe them in this post.

Most of my talks contain a demo. A fair share of these demos require multiple 'infrastructure' dependencies: a database (or more), Elasticsearch, you name it. To ease my setup and avoid stuffing my machine, I use either Docker Compose or Kubernetes locally on my Mac. Both rely on Docker Desktop. To expose a cluster Service on my host, I use nodePort. Hence, I set a dedicated node port for each service. I need to remember each of them for each demo. Worse, services might be (are) declared across
