SRE Linux pivot

Feb 20, 2020 3 Comments

I'm an SRE, devops, etc, whatever this years hip term for the role is.

I'm something like a 60/40 ops/coding split, but could code more too. I'm great at diving into operational issues, automation, etc. I'm not a pure sysadmin GUI clicker type (there are sadly a lot of those around here that call themselves SREs...) I have a CS degree, O(n) and figuring out the complexity of an algorithm are no problem for me.

My problem is the vast majority of my experience since college (and even during) is Windows-based. I know being a Windows SRE inside out at this point, and I'm interested in learning the Linux stack both professionally to open up more potential job opportunities as well as personal interest. What are some good resources (preferably hands on, for me personally all my best SRE experience has come from actually troubleshooting/fixing/automating) for learning *nix fundamentals? I know I could read books/man pages but that's just memorization that I'm trying to avoid. I don't need the most basic stuff, I can get around a shell, file permissions, editing config files, etc. but I don't know how I would go about troubleshooting an issue on Linux the way I would on Windows.

    Honestly the best thing is often to start a personal project and decide to use Linux. Home file server is a classic. Security camera server (bonus: there're cool documented setups that let you upload images to s3 and have cloud automation do the analysis), email server, etc.
    Any project like this you'll run into dumb shit you get stuck on and will learn a ton researching and experimenting to figure it out

    • Been there been doing that for years. Pfsense all the time, and some variation of freenas, Plex on Linux, and proxmox (replacing the freenas for zfs) or esxi. I'm kinda borderline obsessive with my homelabbing. I have a basement and ~5 year old data center gear is so damn cheap on eBay... My house might have 40G fiber in places...

      The problem is they've by and large been stable so I haven't had to do a lot of tinkering or fixing. I've thought about setting up ELK to monitor pfsense logs for the hell of it, maybe that will be better learning.
