Capture Screenshots

Use Playwright to capture the web desktop after starting the container:

bash
bash scripts/make-screenshot.sh

Defaults:

bash
TARGET_URL=http://localhost:8080/
OUTPUT_PATH=screenshots/desktop.png

You can override them for custom captures:

bash
TARGET_URL=http://localhost:8080/ OUTPUT_PATH=screenshots/custom.png bash scripts/make-screenshot.sh

Included Tools

• Node.js (LTS)
• C++ Compilers (gcc, g++, clang, clang-format)
• Go (1.21.5)
• Terraform
• Visual Studio Code
• Ghostty terminal emulator
• Claude Code AI coding agent (Anthropic)
• OpenCode AI coding agent for the terminal
• Codex AI coding agent for the terminal
• man (Linux manual pages)
• Docker CLI (connects to external Docker daemon)
• kubectl
• Git
• Zsh with Oh My Zsh (robbyrussell theme)
• Web-based RDP (XFCE desktop via noVNC on port 8080)

Building the Image

bash
docker build -t coder-dev .

Troubleshooting Build Issues

If you encounter "not enough free space" errors during build:

1. Free up Docker disk space:

   bash
   docker system prune -a --volumes
   

2. Increase Docker Desktop disk allocation:

   • Docker Desktop → Settings → Resources → Advanced
   • Increase the disk image size (recommended: at least 60GB)

3. Build with BuildKit (more efficient):

   bash
   DOCKER_BUILDKIT=1 docker build -t coder-dev .
   

Running the Container

Web RDP Access (Default)

The container starts with a web-based RDP desktop by default on port 8080:

bash
docker run --rm -d -p 8080:8080 \
  -v $(pwd):/home/developer/workspace \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v ~/.claude:/home/developer/.claude \
  -v ~/.config/opencode:/home/developer/.config/opencode \
  -v ~/.config/codex:/home/developer/.config/codex \
  --name coder-dev \
  coder-dev

Then access the desktop at: http://localhost:8080

Basic Usage (Shell Only)

To run with shell access instead of RDP:

bash
docker run --rm -it coder-dev /bin/zsh

With Volume Mount (Recommended)

Mount your local workspace into the container:

bash
docker run --rm -it -v $(pwd):/home/developer/workspace coder-dev

With Docker Socket (for Docker CLI)

To use Docker commands inside the container (connects to host Docker daemon):

bash
docker run --rm -it -v /var/run/docker.sock:/var/run/docker.sock coder-dev

Complete Setup (Volume + Docker Socket + AI Auth)

bash
docker run --rm -it \
  -v $(pwd):/home/developer/workspace \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v ~/.claude:/home/developer/.claude \
  -v ~/.config/opencode:/home/developer/.config/opencode \
  -v ~/.config/codex:/home/developer/.config/codex \
  coder-dev

With Port Forwarding

If you need to expose ports (e.g., for web development or RDP):

bash
docker run --rm -d -p 8080:8080 -p 3000:3000 \
  -v $(pwd):/home/developer/workspace \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v ~/.claude:/home/developer/.claude \
  -v ~/.config/opencode:/home/developer/.config/opencode \
  -v ~/.config/codex:/home/developer/.config/codex \
  --name coder-dev \
  coder-dev

Access web RDP at: http://localhost:8080

Detached Mode (Background)

Run container in detached mode (use docker exec to access):

bash
docker run --rm -d --name coder-dev \
  -v $(pwd):/home/developer/workspace \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v ~/.claude:/home/developer/.claude \
  -v ~/.config/opencode:/home/developer/.config/opencode \
  -v ~/.config/codex:/home/developer/.config/codex \
  coder-dev

# Access the container
docker exec -it coder-dev /bin/zsh

Quick Commands

Verify Installed Tools

bash
node --version
dotnet --version
go version
terraform version
docker --version
kubectl version --client
gcc --version
clang --version
code --version
ghostty --version
opencode --version
codex --version

Access Container Shell

The container starts with zsh by default. You can also access it with:

bash
docker exec -it <container-id> /bin/zsh

AI Tool Authentication

The container includes Claude Code, OpenCode, and Codex AI coding tools. To use them with your existing authentication, mount the config directories from your host:

These volumes are declared in the Dockerfile and included in all docker run examples above. If you haven't authenticated with these tools on your host yet, the directories will be created automatically and you can authenticate from inside the container.

Notes

• The container runs as a non-root user (developer)
• Default working directory: /home/developer/workspace
• Docker CLI connects to the host's Docker daemon (no Docker daemon runs inside the container)
• All tools are installed system-wide and available in PATH
• Default behavior: Container starts web RDP desktop on port 8080 (XFCE via noVNC)
• To access shell instead of RDP, override CMD: docker run --rm -it coder-dev /bin/zsh
