Docker images for portable development environments

Docker Dev

Spin up a container to develop from anywhere!

To run, just:

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

Alternatively, if on Linux:

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

Images

Language Images

• ubuntu-dev-base: Ubuntu image with a few presets such as docker of already installed. It is also configured to allow passwordless sudo just like those vagrant images. Tags available:
  • latest: Ubuntu xenial based image.
  • bionic: Ubuntu Bionic Beaver (18.04) image.
• power-tmux: Powerline + Tmux. Based from the ubuntu-dev-base image. Images available:
  • bionic
• nvim: NeoVim image. Based from ubuntu-tmux. Language agnostic vim setup (no language-specific plugins in there). Images available:
  • bionic
• nodejs-dev: nvm + nodejs specific configurations. Tags available:
  • bionic-carbon: Ubuntu 18.04 + NodeJs 8.
  • bionic-dubnium: Ubuntu 18.04 + NodeJs 10.
• rust-dev: NeoVim configuration and autocomplete for the Rust language.
  • stable uses rust stable with YouCompleteMe backed by only racer.
  • nightly uses rust nightly with deoplete backed by RLS.
• py-dev: Python configuration with autocomplete for python and ptpython.
  • bionic: Ubuntu 18.04 + python 3.6
• ruby-dev: Ruby image with language server. Tags:
  • bionic: Ruby 2.3 pre-installed.
• c-dev: Ubuntu Bionic image for c development with cquery for completions. There is only a bionic tag.

Database Images

• pg-dev: Postgresql image with pgcli, a command line client with autocompletions and syntax highlighting. Tags correspond to the Postgresql version:
  • 9.3
  • 9.6
  • 10
  • 11
• my-dev: MySql image with mycli utility. Tags correspond to the mysql version:
  • 5.6
  • 5.7
  • 8.0
• mongo-dev: Official mongodb image with Mongo Hacker added. Tags correspond to the mongdb version:
  • 4.1

Vim Configuration

Vim configurations are broken down into three parts:

• init.vim: This is the equivalent for .vimrc in NeoVim.
• plugin.vim: This contains all plugins which will be installed using vim.plug.
• post-plugin.vim: Contains all plugin-specific configurations for Neovim. Configurations which aren't plugin-specific reside in the init.vim file.

Breaking it down this way allows one to just run cat addition.vim >> $XDG_CONFIG_PATH/file to add new plugins and configs for specific programing languages and libraries.

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

This is what I use on my current machine to get it working with everything.
