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. You can first select images you want to work on with keys similar to Dired:

• mark,
• unmark,
• toggle marks,
• Unmark all.

Then you can apply actions on them:

• Delete,
• Fetch (pull),
• Run,
• Push

When you press one of these keys you'll be presented with an interactive interface à la Magit.

It works the same for containers: M-x docker-containers, see the documentation.

We can also manipulate images and containers programmatically with the functions provided that form an API.
