01Start Warda
In an empty folder, download the file of the latest release and start it. Warda uses the network of the machine: ports 53 (DNS), 80 and 443 (interface) must be free.
curl -fsSLO https://github.com/warda-dns/Releases/releases/latest/download/docker-compose.yml
docker compose up -d02Ports 80 and 443 already taken
A reverse proxy (Traefik, nginx, Caddy) or a NAS already holds them? Before starting, change these two lines under environment:, then open Warda at http://<address>:8080. Never publish Warda on the Internet through that proxy.
Port 53 cannot move: the devices only ask that port. Stop the other DNS server; on Debian or Ubuntu it is often systemd-resolved (DNSStubListener=no in /etc/systemd/resolved.conf, then restart it).
WARDA_HTTP_LISTEN: ":8080"
WARDA_HTTPS_LISTEN: ":8443"03The address and the password
The first command shows the address to open, the second the default password, to use within the hour after the start. If a port is in use, the log names it, with the program that probably holds it.
docker logs warda
docker exec warda warda setup-info04Update
With Docker, Warda installs nothing by itself: every 6 hours it checks for a new version signed by its publisher and shows it in System. Write the new version in the line image: of the file, then pull and restart. The nightly copy of the backups to a USB drive is not done in Docker.
docker compose pull && docker compose up -d
