I am also pretty new to docker and it took a few days to get my head into it, but I am using it mainly as a contained dev environment, similar to the way we use vagrant. I am finding that docker is much better suited to complex environments, and a lot easier to update. Contrary to your fears of everyone having to learn docker to develop, I see it as a tool that allows every developer on a team to be brought into new technology without having to learn all about a new toolchain. We are using docker-compose for this. Everyone has to install docker, and have some cursory knowledge of docker-compose commands, but that's it. As an example, I recently shoehorned an angular2 front end into an existing project. Without docker, this means every developer needs node and all the dependencies before they begin to work. With docker-compose, the next time they start up the environment, the npm container installs all of their dependencies, and the typescript compiler container listens and compiles all changes to the webroot. The other developers don't even need to know what node is, or that it's being used! Docker is a very powerful tool with a lot of untapped potential I'm sure. I've no experience with docker in production, however.
