cjimti/emacs repository overview

⁠Background

see: https://mk.imti.co/dont-install-emacs/⁠

⁠Container-as-command: Emacs

I use this for servers with Docker but no emacs. The container works best and is most transparent when it mounts the user's home directory. Mounting a home directory requires a lot of trust in the container. So who am I? You probably want to build your container and lose the need to trust me on this one; it's up to you. Clone or fork github.com/cjimti/cmd-emacs⁠, if you would like to create your own. You can also easily cut-and-paste the Dockerfile⁠ into your own.

See the Build Container section below to make your own.

⁠Install / Run Emacs

Installing the container-as-command emacs is simply creating an alias by adding this line to your .bash_profile or .bashrc:

alias emacs='docker run --rm -it -v "$PWD":/src -v "$HOME":/root cjimti/emacs'

Open a new terminal and run:

alias emacs

Run emacs:

emacs

The files in your current directory mount to the path /src in the container.

Open a file in the new emacs/docker command:

emacs ./somefile.yml

⁠Debug

docker run --rm -it -v "$(pwd)":/src --entrypoint sh cjimti/emacs

⁠Build Container

Change cjimti to your own Docker Hub username if you intend to push the container.

⁠Build:

docker build -t cjimti/emacs .

⁠Push:

docker push cjimti/emacs
