I’ve been a software engineer for 10 years now but want to work with Linux more in a professional setting (not to mention the number of layoffs in the the dev industry has me thinking a backup plan might be a good idea). I have been using Linux exclusively on my personal machine for about 15 years now so I’m not too worried about passing the LFCS but I’m wondering of its worth it. What kind of job opportunities would it open for me? Should I focus more on dev ops? Security? Straight SysAdmin?
Really great answer, I feel too like the focus is more on “cloud” tooling now.
I must have missed some news, when did it go proprietary?
Sorry, I guess I meant Docker Desktop, and some of their other proprietary business/enterprise tools (like Docker Scout) that companies have started to use, the stuff that requires a paid subscription. The Docker engine itself remains opensource of course, but a lot of their stuff that’s targeted at enterprises isn’t. These days when companies say “Docker” they don’t mean just the engine, they’re referring to the entire ecosystem.
Also, I have a problem with Docker itself. My main issue is that, on Linux, native container tech like Podman/LXD work, perform and integrate better (at least, from my limited experience), but the industry prefers Docker (no surprises there). As a Linux guy, naturally I want to use the best tool for Linux, not what’s cross-platform (when I don’t care about other platforms). But I can understand why companies would prefer Docker.
Ah I see what you mean, that stuff is pretty annoying.
Well at least the core tech remains open, though I agree, I would like to see more agnosticism from the industry in regard to the tool implementing the containers, since they’re pretty much all interoperable to a certain extent, as I understand
Docker is questionable open-source and depends on Dockerhub that isn’t open.
Dockerhub isn’t a hard requirement though, there are other container registries out there
No, but that’s what everyone ends up using and the thing is designed to work really well with dockerhub and not so much with others.
