DevOps with Kubernetes

What's this all about?

  • I am an advocate of project-based learning, and to gain firsthand experience with Kubernetes, I closely followed the guide provided by devopswithkubernetes. The overarching approach is to compartmentalize each exercise, framing them as distinct projects with specific learning objectives. Within these exercises, you'll discover opportunities for focused, hands-on learning. I am sure there will be many errors with readme, I intend to revisit and fix them over time. Please feel free to contribute if you like.

How to contribute?

  • I welcome contributions from the community to improve this tutorial. I am sure the readme of each project could be improved vastly. Before starting any work, search for existing issues to see if your contribution is already discussed or in progress. If not, feel free to open a new issue to discuss the changes you'd like to make or the problems you'd like to address.
