After reading about some people's issue with Docker hosts' time going out of sync, I realized that my Docker host on Digital Ocean (created via docker-machine) may want ntp running on it, and that got me thinking about system updates to the Docker hosts in general.

There has already been a good discussion on applying updates to the actual docker services -- with general agreement that rebuilding images from updated base images is good solution -- but I haven't seen much focus on the Docker hosts themselves.

For those using Docker in a production environment, are you even bothering with docker-machine, or are you building and maintaining your Docker hosts with traditional tools like Chef/Puppet/etc?
