On: Puppet 4 is now production-ready

Immutable infrastructure can be implemented using sole Dockerfile and Docker Compose. And Docker Machine can create/manage whole environments on various types of cloud providers.

They are not solving the same problem at all.

You'd still need something to bring your docker up to the desired state, unless you want to do it with bash commands line by line.

[Gigablah → borplk]

It doesn't take a lot to install and configure the Docker daemon, and if you're running a cluster you'd want to put that in your cloud-init. Of course, you can always use ansible-pull to bootstrap your hosts.

Is it cloud-init all the way down? ;)
