• create certificates (see create-certs.sh)
• move the certificates to a directory somewhere in /Users/..... We'll be able to copy files from there into the VM as it will already be mounted by Docker.
• attach to the TTY: screen ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/tty
• copy the certificates into the vm: mkdir -p /etc/docker/certs.d/mydomain.com:5000 && cp /Users/.../certs/domain.crt /etc/docker/certs.d/mydomain.com/ca.crt
• restart Docker: service docker restart
