Docker is what gave me courage to expand my skill set with devops! Previously I was terrified of touching any server for fear of messing something up and then having to twiddle with tens of config files and apt-get. Now I just rebuild the image and deploy. Its 100 times easier. I missed the ansible train, but my understanding is that ansible is fundamentally just doing the same stuff, just automated and better documented. If you make a mistake, you can mess up many servers and it will be a pain to fix.
