There's a sad truth that many of us engineers do not want to accept. The most successful solutions are ones that do not require quality or diligence from the practitioner. There are absolutely better way to do things than Docker. Pretty much everything about Docker is terrible, but it solves one problem in a very simple way that most anybody can use. That solution is that it creates a fairly portable software package that is easy to create and run.

Now there are tons of issues in the way things are created and ran with Docker, but they will all be sufficiently addressed over time. By adding enough things around the edges (better orchestration and resource management tools, better security scanners, etc) the ends goals and needs of "business" will be met. In the end you have a messy solution compensated by a series of tools. The pros outweigh the cons.
