dkdev/dev-env

Custom Docker image extending lscr.io/linuxserver/code-server with the Dkdev development toolchain pre-installed.

What it includes

Built into the image (Dockerfile):

• Build deps for Python (build-essential, libssl-dev, libffi-dev, etc.)
• Docker CLI + Compose plugin (daemon comes from host via socket mount)
• gh CLI (GitHub)
• git, tmux, vim, htop, jq, less
• postgresql-client, redis-tools

Installed at container start (init scripts in /custom-cont-init.d/):

• pyenv + Python 3.12.7 (in /config/.pyenv)
• nvm + Node 22.11.0 LTS (in /config/.nvm)
• Poetry (in /config/.local/bin)
• Claude Code CLI (npm global in nvm path)

Init scripts are idempotent — they detect existing installs and skip reinstall.

Usage

Local build (on the VPS or any host with Docker):

make build
docker images | grep dkdev/dev-env

Pull from registry (when published to ghcr.io):

make pull

Update flow

1. Edit Dockerfile or init/*.sh
2. make build
3. cd /docker/visual-studio-code-server-mrhj && docker compose up -d --force-recreate
4. Init scripts run automatically; new toolchain installs idempotently in /config

Troubleshooting

Init scripts not running on container start:

docker logs visual-studio-code-server-mrhj-code-server-1 2>&1 | grep -E "custom-cont-init|pyenv|nvm"

pyenv install fails (missing build dep): Check the apt packages in Dockerfile cover the pyenv build wiki.

Docker socket not accessible from inside container: Verify docker.sock mount in docker-compose.yml and that user abc (uid 1000) is in group docker on the host.
