Books: (I would start with the first, but added the other two as I found
them helpful for different reasons. I have a link below to get a free copy
of the first)
- Kubernetes Up and Running
- Good summary of the various aspects of K8s. Each chapter does a
good job explaining each concept
- Programming Kubernetes
- This is a great book on programming Kubernetes Operators. This
really gets into the inner workings of Kubernetes
- Not needed for intro to K8s, but I highly recommend it if you are
interested in building K8s controllers
- Kubernetes Patterns
- Each chapter is a pattern that helps demonstrate interesting
solutions
- I found this to be a nice supplement because it opened my eyes to
new ways to build solutions
