I knew at first it was good for something, so I installed it. It wasn't until I worked with my boss on it that I actually grew to understand what it was and how it worked.

Work. Some dude wanted the same environment locally as when it was deployed. He didn't achieve his goal (docker was too new, local caches kept breaking everything, IDEs didn't have docker integration, etc.), but it put me on a path of frustration and finally learning how docker worked internally to fix bugs. At the time, I hated it and just used vagrant, but with time it got better. Now I'm on nix though and docker seems outdated now.
