Docker reference

Eventually need to migrate info from this reference into a format that makes more sense for me. Also definitely include info on running desktop apps in docker. Maybe cover the JSON outputs of the inspect commands.

Docker uses a client-server architecture. There is no requirement that the daemon and client be run on the same machine.

Docker containers are not full VMs but instead special processes running in the host (on Linux).

Images contain the app binaries and dependencies, along with instructions on how to build a container.

Much of Docker's flexibility follows from Dockerfile inheritance. Every Dockerfile begins with a FROM directive indicating a base image.

A full Dockerfile reference is available here.

Docker Compose eases the instantiation of multi-container applications.
