TL;DR - Cannot get cmk-agent-ctl register to connect to a site running in a Docker container and using a different port ( -p 8010:8000 )
Edit: Smashed it! The command that works for my instance is
cmk-agent-ctl register --hostname oak --server oak:8010 --site cmk --user cmkadmin
The hint in the docs was at https://docs.checkmk.com/latest/en/managing_docker.html " 2.3. Setting your own site ID"
… the ID of the site created in the container will be
cmk.
That’s the site name to use when registering, not the container name.

Thank you for help resolving this.

Docker command to start - note that port 8000 is already in use so I have mapped that to 8010. The site is running and I can connect/login using http://oak
