Cockpit docker compose and docker file

Question

I need to create a custom docker image with Cockpit and ubuntu. But I can't start the service and expose it once it has been installed.

FROM ubuntu:latest

ENV DEBIAN_FRONTEND=noninteractive TZ=Australia/Brisbane

RUN apt-get update -qq -y && apt-get upgrade -y && \
    apt-get install -y curl net-tools && \
    apt-get install -y cockpit


EXPOSE 9090

CMD [ "command to run and expose cockpit" ]

I tried with:

service cockpit.socket start && tail -f /dev/null

# And
service cockpit start && tail -f /dev/null

Error: Service not found: cockpit.socket

And also with:

CMD [ "cockpit" ]

Error: Command not found

Also it seems I can't use systemctl in a docker Image.
