Docker Compose Deployment

The Compose stack contains two services:

• rmm-server: Go API, web UI, and persistent SQLite database.
• tunnel-ssh: SSH endpoint used by routers for reverse SSH tunnels.

Published ports:

• 18080/tcp: RMM API and web UI.
• 2222/tcp: router-to-server SSH tunnel connection.
• 22000-22099/tcp: temporary operator endpoints created by remote sessions.
• 22100-22199/tcp: internal LuCI proxy forwards; these are not published by Compose.

1. Configure Secrets

Create the local environment file:

Copy-Item .env.example .env
notepad .env

Replace RMM_ENROLLMENT_TOKEN and RMM_OPERATOR_TOKEN before exposing the server outside a trusted network.

2. Start The Stack

docker compose up -d --build
docker compose ps
docker compose logs --tail 100

Open:

http://127.0.0.1:18080

The SQLite database and SSH keys are stored in named Docker volumes.

For HTTPS and domain-based access, use npmplus.md or the optional Caddy overlay described in reverse-proxy.md.

3. Generate And Install The Tunnel Key

Generate the router tunnel key before starting Compose:

mkdir -p secrets
ssh-keygen -t ed25519 -N '' -C rmm-router-tunnel -f secrets/router_tunnel_key
chmod 600 secrets/router_tunnel_key

Compose mounts only secrets/router_tunnel_key.pub into the SSH sidecar. The private key remains on the deployment host and must be installed on approved routers.

OpenWrt 25 uses apk. Install the OpenSSH client:

apk add openssh-client

Install the key without scp or SFTP:

Get-Content -Raw .\secrets\router_tunnel_key | ssh root@10.10.10.1 "umask 077; mkdir -p /etc/rmm-agent; cat > /etc/rmm-agent/tunnel_key; chmod 600 /etc/rmm-agent/tunnel_key"

Update /etc/rmm-agent.conf:

TUNNEL_IDENTITY_FILE="/etc/rmm-agent/tunnel_key"

Deploy the latest agent and restart it:

Get-Content -Raw .\agent\openwrt\rmm-agent.sh | ssh root@10.10.10.1 "cat > /usr/bin/rmm-agent; chmod +x /usr/bin/rmm-agent; /etc/init.d/rmm-agent restart"

4. Open A Remote Session

In the device Remote access panel use:

• Tunnel server: the Docker host IP reachable by the router, for example 10.10.10.2.
• Server SSH port: 2222.
• Remote port: leave empty for automatic selection.
• Router SSH port: 22.
• Duration: 15 min.

After the agent reports success, connect using the command shown in the UI:

ssh -p 22022 root@10.10.10.2

The actual port is selected per session.

Operations

View logs:

docker compose logs -f rmm-server
docker compose logs -f tunnel-ssh

Restart:

docker compose restart

Stop without deleting data:

docker compose down

Back up the SQLite database:

docker compose cp rmm-server:/data/rmm.db .\tmp\rmm-backup.db

Security Notes

• Restrict ports 18080, 2222, and 22000-22999 with the host firewall.
• Port 2222 must be reachable by managed routers.
• Ports 22000-22099 should only be reachable by trusted operators or VPN clients.
• Use long random enrollment/operator tokens.
• Current MVP uses one persistent router tunnel key. Per-device or per-session keys are the next hardening step.
