Docker Dev

Spin up a container to develop from anywhere!

To run, just:

docker run -ti aghost7/nodejs-dev:boron tmux new

Alternatively, using slipway:

python3 -m pip install --user slipway
slipway start aghost7/nodejs-dev:noble

Terminal

Lately, I've been using alacritty. You can find my configurations here. Gnome terminal and/or iTerm2 works fine though.

Language Images

Only the :noble tag is currently maintained.

• dev-base: Ubuntu base image with neovim and tmux.
• nodejs-dev: nvm + nodejs specific configurations. Tags available:
• rust-dev: NeoVim configuration and autocomplete for the Rust language.
• py-dev: Python configuration with autocomplete for python and ptpython.
• c-dev: Ubuntu Bionic image for c development with cquery for completions.
• deno-dev: Ubuntu Bionic image for deno development with bash completions. Tags Available:
• devops: Python image with additional tools (e.g., terraform) for devops related tasks.

Database Images

• pg-dev: Postgresql image with pgcli, a command line client with autocompletions and syntax highlighting. Tags correspond to the Postgresql version.
• mongo-dev: Official mongodb image with Mongo Hacker added. Tags correspond to the mongdb version.

Calling Docker on the Host

The docker daemon run over a socket. The command line tool is just a client to the daemon. In other words, if we make the socket connectable from within the container we're in business.

For some reason it needs privileged to work as well.

docker run -ti --rm \
	--privileged \
	-v `readlink -f /var/run/docker.sock`:/var/run/docker.sock \
	aghost7/ubuntu-dev-base:latest \
	tmux new

SSH Forwarding and Git

For ssh, just pass the socket over to the container.

docker run -ti --rm \
	-v $SSH_AUTH_SOCK:$SSH_AUTH_SOCK \
	-e SSH_AUTH_SOCK=$SSH_AUTH_SOCK \
	aghost7/ubuntu-dev-base:latest \
	tmux new

I like to avoid having to reconfigure git every time, so I mount a volume for .gitconfig. ~/.ssh/known_hosts is also anoying.

Getting the Clipboard Working

Basically, X11 is built in a manner that allows sending display data over the wire. I've managed to run GUI applications from a headless server through an ssh connection in the past. The way I'm doing this is through the same old unix socket trick for controlling the docker daemon that's on the host machine.

docker run -ti --rm \
	-e DISPLAY=$DISPLAY \
	-v /tmp/.X11-unix:/tmp/.X11-unix:ro \
	aghost7/ubuntu-dev-base:latest bash

On the host you'll need to disable one of the security features in X11.

xhost +si:localuser:$USER > /dev/null
