I don't use Docker for any of my personal projects. I've found that a bit of bash and systemd can do pretty much everything I need. I used to be a big Docker fan, but at some point I realized that I was just avoiding learning proper server management and core automation tools (like bash, which isn't so bad, it turns out).

If you work with other people, then yes, definitely use Docker. It adds a layer of foolproofing that's much needed in larger teams, and it's basically a lingua franca for deploying things these days.
