Robotics Development Workspace

Docker workspace for robotics development with ROS 2, Python, C++, and Claude Code.

Provisions a Docker container as a Coder workspace with selectable GPU passthrough, Docker-out-of-Docker, and a persistent home directory.

Preinstalled tools

• ROS 2 Desktop, with colcon, rosdep, and vcstool
• Python 3 with pip, venv, and uv
• GCC, Clang, CMake, Ninja, GDB, and Valgrind
• Claude Code
• Docker CLI for Docker-out-of-Docker
• Gitea CLI (tea)
• code-server and JetBrains Toolbox support

Parameters

Parameter	Description	Default
GPU Assignment	Which GPU(s) to attach: GPU 0, GPU 1, or both. GPU 1 is shared with the Ollama and Immich stacks.	GPU 0

Prerequisites

The host needs the NVIDIA container toolkit for GPU passthrough. Coder itself runs as a container and creates workspaces through the host's Docker socket, so its service needs the socket mounted and the host docker group added:

volumes:
  - /var/run/docker.sock:/var/run/docker.sock
group_add:
  - "987"

Workspaces get the same GID through the docker_group_id template variable, which defaults to 987. Confirm the host GID with getent group docker and override the variable if it differs.

Ollama

OLLAMA_HOST is preset to http://host.docker.internal:11434. Verify with:

curl "$OLLAMA_HOST/api/tags"

Gitea

The tea CLI manages repositories, issues, and pull requests from the workspace:

tea login add --name sirblob --url https://git.sirblob.co --token <token>
tea repos list

Docker-out-of-Docker lets you build and push images to the registry:

docker login git.sirblob.co -u <user> -p <token>
docker build -t git.sirblob.co/<user>/<image>:<tag> .
docker push git.sirblob.co/<user>/<image>:<tag>

ROS 2 environment

The ROS 2 distribution is chosen from the base image's Ubuntu release at build time: Jammy gets Humble, Noble gets Jazzy. Override it with the ROS_DISTRO build argument.

/etc/bash.bashrc sources the ROS 2 setup script, so every interactive shell has the environment ready. In a non-interactive shell, source it directly:

source /opt/ros/*/setup.bash

Updates

The image is built with the base packages already upgraded, and the agent runs apt-get update and apt-get upgrade on every workspace start so a long-lived container keeps picking up security updates.

Persistence

/home/coder is mapped to a host directory and survives workspace restarts. The rest of the root filesystem is ephemeral, so every preinstalled tool lives under /opt or /usr/local instead of the home directory.
