https://professionallinuxusersgroup.github.io/course-books/lac/u9intro/ — this course I like quite a lot, it’s very in depth about Linux overall, covering containers and kubernetes.

There is also this site: https://killercoda.com/ , which has online interactive environments and tutorials.

For example: https://killercoda.com/het-tanis/course/Kubernetes-Labs

https://kubernetes.io/docs/ Just start with the official docs (not joking).

Tutorials, Concepts, and Tasks sections are detailed enough for basic cluster deployment and management.

Also the API reference page (https://kubernetes.io/docs/reference/kubernetes-api/) contains a lot of valuable information.

Dive in. Ubuntu has microk8s which is ridiculously easy to install and run. Don’t use helm charts. Start with just understanding how to deploy pods and services. Searx can be very easy to get started with since it doesn’t have any database or volume requirements - just the application itself.

Lots of these around, been following this slowly
