How do I use my Docker server?

1. In the panel, open My servers and click your server.
2. On the Overview tab, wait for the App row to say "Docker is ready". The page refreshes itself.
3. Note the values in the Connection address, Username and Password rows.
4. Connect from your computer's terminal, using your own address instead of this example: ssh [email protected]
5. Check that Docker works: docker run --rm hello-world
6. In the folder with your own compose.yaml, start your services: docker compose up -d

What's on the server

• Docker and Docker Compose are installed. There is no other app or web interface, so the panel shows no site address.
• Container logs are capped so they can't fill the disk: at most 3 files per container, 10 MB each.
• The firewall (ufw) is on, and only port 22 for SSH is open to the outside.
• fail2ban watches SSH, and operating system security updates install automatically.

Be careful when publishing ports

Docker bypasses ufw rules for the ports you publish. Any port you publish with ports: in compose.yaml is open to the outside, even without ufw allow. So don't publish services that should only be reached internally, such as databases. Containers can reach each other over the Docker network.

For a service you run outside Docker, open the port with ufw yourself: ufw allow 8080/tcp
