openchamber --port 8080              # Custom port
openchamber --ui-password secret     # Password-protect UI
openchamber tunnel help              # Tunnel lifecycle commands
openchamber tunnel providers         # Show provider capabilities
openchamber tunnel profile add --provider cloudflare --mode managed-remote --name prod-main --hostname app.example.com --token <token>
openchamber tunnel start --profile prod-main
openchamber tunnel start --provider cloudflare --mode quick --qr
openchamber tunnel start --provider cloudflare --mode managed-local --config ~/.cloudflared/config.yml
openchamber tunnel status --all      # Show tunnel state across instances
openchamber tunnel stop --port 3000  # Stop tunnel only (server stays running)
openchamber logs                     # Follow latest instance logs
OPENCODE_PORT=4096 OPENCODE_SKIP_START=true openchamber                    # Connect to external OpenCode server
OPENCODE_HOST=https://myhost:4096 OPENCODE_SKIP_START=true openchamber  # Connect via custom host/HTTPS
openchamber stop                     # Stop server
openchamber update                   # Update to latest version

Tunnel behavior notes

• One active tunnel per running OpenChamber instance (port).
• Starting a different tunnel mode/provider on the same instance replaces the active tunnel.
• Replacing or stopping a tunnel revokes existing connect links and invalidates remote tunnel sessions.
• Connect links are one-time tokens; generating a new link revokes the previous unused link.

Optional env vars:

environment:
  UI_PASSWORD: your_secure_password
  CF_TUNNEL: "true"   # Options: true, qr, password

Data directory: mount data/ for persistent storage. Ensure permissions:

mkdir -p data/openchamber data/opencode/share data/opencode/config data/ssh
chown -R 1000:1000 data/

openchamber --daemon    # Run in background
openchamber stop        # Stop background server
