I previously installed CoreDNS on a Docker container using the following command:
docker run -d --name coredns --restart=always --volume=/home//Documents/docker/coredns/:/root/ -p 53:53/udp coredns/coredns -conf /root/Corefile
CoreDNS is working just fine on that container.
I’m trying to install CoreDNS on a second container on another host, but for this one I’d like to use a compose file instead of that Docker run command. But I can’t figure out how to represent that -conf argument from the run command onto the compose file. Any ideas?
version: '3' services: coredns: image: coredns/coredns container_name: coredns restart: always volumes: - /home//Documents/docker/coredns/:/root/ ports: - "53:53/udp" command: -conf /root/CorefileThis should do it.
The bit after the image when running
docker runfrom the command line is thecommand, which are arguments passed to the container’s entrypoint. So in your case, it would becommand: -conf /root/Corefilehttps://docs.docker.com/compose/compose-file/compose-file-v3/#command
