Docker

In the emacs world we have some packages to work with Docker.

Syntax highlighting

This is possible with dockerfile-mode (in MELPA). It also offers the ability to build the image directly (C-c C-b) from the buffer.

Manipulating images and containers

For that you'll want docker.el (in MELPA too). It defines a docker-images major mode to manipulate docker images: call it with M-x docker-images and use the keys: Delete, Fetch (pull), Run, Push and the same with containers.

Silex: I'm the author of the above docker.el, it'll soon feature documentation & everything, just be a little patient :)
