Most people learn Docker by copying commands into a real machine. It works until something breaks and nobody explains why.
DockerLinux is a free game that fixes that: a simulated Linux + Docker terminal in the browser, with 10 levels of small missions, from pwd to Docker Compose. Nothing to install, nothing real to break.
After the launch, developers in the comments asked for two things: pipes and error messages identical to real Docker. Both are live now, plus a few more things:
🔗 A new level on pipes: ls | wc -l, grep, head, tail, docker ps | grep web
💬 Error messages that match real bash and Docker word for word, so nothing surprises you on a real server
❄️ Daily streaks with freezes: finish a level to earn one, and it covers a day you miss.
🏆 An achievements page with 29 badges (5 are secret), progress bars and a practice-day grid
💾 An optional free account with no password (a 6-digit email code) to continue on any device
It's aimed at students, junior devs and anyone moving into DevOps or cloud, and it works on a phone too.
If you know Docker well, we'd love your eye on it: where does the simulation behave differently from the real thing in a way that could mislead a beginner?
