Frequently asked questions (FAQ)

Ubuntu repos or docker.com?

For a current engine: official Docker repo. Distro packages lag.

compose vs docker-compose?

2026: docker compose v2 plugin. Hyphen binary is legacy.

Add user to docker group?

Convenient, but docker.sock is root-equivalent. Prefer rootless or a deploy user.

UFW and Docker?

Docker often bypasses UFW via iptables. Bind to 127.0.0.1 and put a proxy in front.
