Feature-Rich Docker Workspaces

Provision powerful Docker containers as Coder workspaces with this template. It features selectable GPU passthrough, Docker-out-of-Docker (DooD), and pre-installs essential development tools via a custom Dockerfile.

Prerequisites

Infrastructure

The host you run Coder on must have a running Docker socket, the NVIDIA container runtime installed, and the coder user added to the Docker group:

sudo adduser coder docker
sudo systemctl restart coder
sudo -u coder docker ps

Features & Architecture

This template provisions the following resources and features:

• Base Image: Custom image built from codercom/enterprise-base:ubuntu.
• Selectable GPU Support: A GPU Assignment parameter chooses which GPU(s) to attach. The default is GPU 0, because GPU 1 is shared with the ollama and immich stacks; pick GPU 1 only or Both GPUs when you need them.
• Docker-out-of-Docker (DooD): Mounts the host's /var/run/docker.sock so you can build and run containers from inside your workspace.
• Ollama Integration: OLLAMA_HOST is preset to http://host.docker.internal:11434, so tools in the workspace talk to the homelab Ollama service out of the box.
• Pre-baked Tools: The custom Docker image comes pre-installed with:
  • System package updates
  • Docker CLI
  • Bun
  • Go (pinned version, installed from the official tarball)
  • SDKMAN! & Maven
  • Opencode
  • jq, build-essential
• Persistent Storage: Uses a persistent host directory mapped to /home/coder so files survive workspace restarts.
• Rich Telemetry: Displays CPU, RAM, Disk, Load Average, and GPU utilization directly in the Coder UI.
• IDE Support: Native integration with code-server (Browser VS Code) and JetBrains IDEs.

Using the homelab services

Ollama

OLLAMA_HOST is already exported in the workspace. Verify with:

curl "$OLLAMA_HOST/api/tags"

Gitea container registry

With DooD enabled you can build and push images straight to the Gitea registry from inside a workspace:

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>

See projects.md in the homelab repo for the full registry workflow.

Note

While your /home/coder directory is persistent, the container's root filesystem is ephemeral. This template builds a custom Docker image to pre-bake tools (Go, Bun, SDKMAN!, Opencode, etc.), ensuring your workspace starts instantly while keeping the tools available.
