I've been having fun playing with Docker lately. I'm hoping to replace our local development environments (on our our work PCs) with lighter weight Docker containers rather than a full blown VM which can be a bit of a resource hog. I've already refined our development environment process to where I can get a developer up and running in about an hour off of a fresh computer where it used to take a day to get everything setup, so switching over to Docker may be the next logical step.
There are some great resources online for Docker. The one I am using is at https://docker-curriculum.com/. I have also been exploring Chef to add in the deployment process. A great tutorial is https://docker-curriculum.com/.
If anybody else has some good resources, please leave them in the comments.
