docker-compose equivalent for docker run arguments like "--foo bar" in compose file?

Question

Given the following docker run command:

  -p 80:80 -p 443:443 \
  rancher/rancher:latest \
  --acme-domain <YOUR.DNS.NAME>

What is the notation for writing --acme-domain in the docker-compose file? I was not able to find this in the docs. Thanks

Everything after the image name in your docker run command line is the "command", which gets executed either by the shell or by your ENTRYPOINT script. The equivalent docker-compose directive is command. For example:

service:
  image: rancher/rancher:latest
  ports:
    - "80:80"
    - "443:443"
  command: "--acme-domain <YOUR.DNS.NAME>"
  ...
