Introduction to Kubernetes - talk
Introduction to Kubernetes (k8s). Here the presentation, as well as all example files are included. I will also include a quick guide on getting k8s running on your computer.
Kubernetes logo and Helm boat logo are property of Cloud Native Computing Foundation. Some images used for explanation purposes are public domain images.

Next steps
Depending on your background, there may be several different next steps. If you are not comfortable with bash and Unix based command lines (like in GNU/Linux), I recommend you to learn more about that first. Docker (and container creation and usage in general) require some knowledge on GNU/Linux and the command line. Already feel comfortable with basic command line usage? Start by creating Dockerfiles.
Want to just play around with examples to get a feel for k8s?
Extra resources
These resources was linked in the talk, and now you can click on them for real :D
- kubectl API docs. API docs for
kubectl. Make sure you are checking the docs for the same version of Kubernetes that you are using. - Smooth Sailing with Kubernetes (comic). Comic about what Kubernetes is, and what problems it solves. From Google.
- KataCoda: Interactive Kubernetes courses and playground. Don't do all! Find out what you want to learn, and pick relevant courses. At least my recommendation.
- Kubernetes for Developers by Joseph Heck: The book I've used to learn more after experiments at home. Great for learning K8s, even though you might not feel 100 % comfortable with container building in general (Dockerfiles)
- kubectl cheatsheet. Cheatsheet for kubectl, the main tool for interacting with your k8s cluster.
- Docker CLI to kubectl. Used to the Docker CLI? Want to know how you can do the same operations to your cluster? This is the place!
- NodePort vs LoadBalancer vs Ingress. Need a refresher on the differences between NodePort, LoadBalancer and Ingress? Look no further!
