Se avete installato Docker come vi avevo indicato, vi basterà eseguire:
docker create \\ --name=duckdns \\ -e PUID=1000 `#optional` \\ -e PGID=1000 `#optional` \\ -e TZ=Europe/London \\ -e SUBDOMAINS=subdomain1,subdomain2 \\ -e TOKEN=token \\ -e LOG_FILE=false `#optional` \\ -v /path/to/appdata/config:/config `#optional` \\ --restart unless-stopped \\ linuxserver/duckdns
