To prepare for the Certified Kubernetes Administrator (CKA) exam, basic Linux skills are a necessity. Being able to move the cursor around quickly in the Bash shell and Vim, create aliases and handy environment variables helps saving precious time during the CKA exam.

Of course there are plenty of cheat sheets around, but creating one yourself that has the commands you like and use, forces you to learn them. I started this series to have cheat sheets of my own that have the generic commands, but also the specific ones for my Windows and MacOS devices if any.

While I was progressing it made sense to share my preparations, so hopefully it serves you well. If so, please like the series at the bottom.

Part 3 – Kubectl time savings (in progress)


This section is about navigating in Bash. On my Mac I use iTerm2 instead of the built-in Terminal and use key mapping preset “Natural Text Editing“.
