Ever had that issue with some dependencies clashing with others, or missing dependencies either stopping an installation or an application from running properly? Upgrades for applications also can run into similar issues. More and more excellent self-contained options are appearing, but Docker has been around a while and there are numerous images ready for instant use as well as easy updating. This is the simplest guide I've seen so far, and I hope it has some future editions being published. For too long I avoided Docker because I just did not bother to understand it.
Containers contain everything an app, tool or service needs to run, including all libraries, dependencies, and configuration files. Containers are also isolated from each other (and the underlying host system), but can communicate through pre-defined channels.
