nginx, jenkins, aws, terraform, bash scripting, tomcat, apache, RHCE, github, ccna, selenium, promethus etc Most of these are things that make sense in a job where they make sense. Of them bash scripting is the only one likely to directly improve your daily life. Maybe Github...or rather Git might help you organize text files. The rest are knowledge domains that are better when sharded across a team so that individuals can show each other how they work. They are mostly bigger than one person can really learn...how big is AWS? AWS includes semi-trailers full of hard disks that will come to a data-center and make a physical copy of data, satellite networks, and items of similar scale. And Kubernetes? its basic design was expected to be run by teams of Google engineers. Not one person with a laptop. Kubernetes is meant not for you. Bash scripting, SQL, Javascript, and Emacs/Vim are things that you can take with you and will always matter at any scale. Good luck.
