I’m referring to all the stuff Docker machine does beyond apt-get install docker. It sets up TLS certs and sockets do you can control the docker daemon remotely. When docker machine works it’s great, but when it doesn’t it’s frustrating.
Its built into docker swarm, afaik. You don't need to do anything special setup for TLS.

Do you have a concrete example of what you ran into? What do you mean by "secure install"?
on osx its just a matter on installing docker4mac and other linux distributions has pre-made packages. I am a linux noob and I was able to setup a 20 machine cluster with swarm trivially on centos7.
I was acutally surprised that I was able to do that so trivially, given I have minimal linux admin experience if any.
