I am a helpdeks engineer trying to migrate to devops/system admin & wondering what should I be learning that gives me highest ROI. I am currently knowledgeable about Linux & bash scripts.

View on HN

Focus on Linux, Linux networking (NAT), containers and kubernetes and basic git understanding.

DNS, well, don't invest to much in it. If anything, DNS is just a networking helper, allowing most protocols to connect "to a string", as opposed to a network address (ip, ipv6).

What do you consider linx networking. I am having a hard time finding relevant resources to learn it. (Pls don't share beej's guide lol)
