Are you running Etcd or something else on 2379 of the docker-machine host?

This should be changed to use a free port returned by the OS to prevent this kind of collision.

No, I don't have etcd running on OSX, I did sudo lsof -i and sudo netstat -A to see if anything was listening on that port but saw nothing on 2379. I started Docker with the Docker Quickstart Terminal (https://docs.docker.com/mac/step_one/) then ran spread cluster up. After that I checked docker logs localkube to see the panic in the output.

@vsimon: Are you checking ports on the host machine or within the VM running docker? If you are using OS X the ports would be opened on the VM.

If you are using docker-machine, SSH onto the machine using: docker-machine ssh <machine name>
(you can get the machine name with docker-machine ls)

Once you are on the machine check which ports have listeners with: sudo netstat -tlp

Also are you running containers other than the ones that come with localkube?
