tomevault-io name: codespace-manager description: Create, manage, and access isolated cloud development environments (codespaces) powered by code-server, Docker, and Cloudflare Tunnel. Pre-installed with Bun, uv, and OpenCode. Use when the user wants to (1) create a new dev environment or codespace, (2) start/stop/restart/delete a codespace, (3) set up an isolated coding workspace, (4) launch a remote VS Code environment, (5) manage development containers, (6) open a browser-based IDE, or mentions codespace, code-server, remote development, dev environment, or cloud IDE.
Codespace Manager
Manage isolated code-server development environments, similar to GitHub Codespaces. Each codespace runs in its own Docker container with a full VS Code editor accessible via browser through Cloudflare Tunnel.
Pre-installed Tools
The custom Docker image includes:
- code-server (VS Code in browser)
- Bun — JS/TS runtime + package manager
- uv — Python package manager + virtual environments
- OpenCode — AI coding assistant (CLI)
- git, curl, wget, build-essential
First-Time Setup
Before creating any codespace, build the Docker image once:
bash scripts/codespace.sh setup
This builds codespace-manager:latest from assets/Dockerfile.txt. Only needed once per host.
Commands
Script location: scripts/codespace.sh (relative to this skill's directory)
# One-time image build
codespace setup
# Create codespace (optionally clone a repo and/or init OpenCode config)
codespace create <name>
codespace create <name> --git <repo-url>
codespace create <name> --opencode
codespace create <name> --git <repo-url> --opencode
# Lifecycle
codespace start <name> # Start and get Cloudflare Tunnel URL
codespace stop <name> # Stop container and tunnel
codespace restart <name> # Stop then start (new URL)
codespace delete <name> # Remove container + data (irreversible!)
# Info
codespace list # List all codespaces with status
codespace status <name> # Detailed status of one codespace
codespace logs <name> # View container logs
codespace url <name> # Regenerate tunnel URL
# Config
codespace password <pass> # Set default password for new codespaces
Password Management
- Default password:
codespace - Set a custom default:
codespace password <your-password> - Override per-session via environment:
CODESPACE_PASSWORD=mypass codespace create foo - Each codespace saves its password at creation time
Natural Language → Command Mapping
| User says | Command |
|---|---|
| "create a codespace called myapp" | codespace create myapp |
| "create a codespace with opencode" | codespace create <name> --opencode |
| "set up a dev environment for this repo" | codespace create <name> --git <url> --opencode |
| "start / launch / open myapp" | codespace start myapp |
| "stop / shut down myapp" | codespace stop myapp |
| "delete / remove myapp" | codespace delete myapp (confirm with user first!) |
| "list my codespaces" / "show environments" | codespace list |
| "get the URL for myapp" | codespace url myapp |
| "set password to xyz" | codespace password xyz |
| "create a python project" | codespace create <name> --opencode (uv is pre-installed) |
| "create a node/bun project" | codespace create <name> --opencode (bun is pre-installed) |
Architecture
- Each codespace = isolated Docker container (
codespace-manager:latest) - Project files persist at
~/codespaces/<name>/projecton the host - Exposed via Cloudflare Quick Tunnel (free, auto HTTPS, temporary URL)
- Each codespace gets a deterministic port (9000-9999, based on name hash)
Important Notes
- Run
codespace setupbefore first use — it builds the Docker image - Quick Tunnel URLs are temporary — they change on restart
codespace deleteis irreversible — confirm with user before executing- Container data (outside
/home/coder/project) does not persist across delete/recreate - Requires: Docker, cloudflared, jq installed on the host
OpenCode Config
When --opencode is used, a opencode.json is created in the project root with:
{
"$schema": "https://opencode.ai/config.json",
"model": "anthropic/claude-sonnet-4-5",
"autoupdate": true
}
Users can edit this file in code-server to change the model or add provider keys.
