Docker compose file for CoreDNS? (alien.top)

submitted 9 months ago by [email protected] to c/[email protected]

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?

The bit after the image when running docker run from the command line is the command, which are arguments passed to the container’s entrypoint. So in your case, it would be command: -conf /root/Corefile
