It looks like docker-machine has a generic driver which connects over SSH, and handles installing certificates for remote connections for you:

I'm wondering if that's easier than my other ideas for #12, which were:

Install Ansible, then use a combination of third-party and Autonomic roles to install Docker, initialise the swarm, and set up remote connection. Benefit:
Add abra command to initialse swarm, have a --server mode to the abra installer script

Holy cow, that machine project looks sick. Just saw this now too https://github.com/JonasProgrammer/docker-machine-driver-hetzner. Pretty handy. Definitely up for trying to see how it handles the certificates!

It looks like Docker machine was "superseded" in favour of infrakit / deploykit, which is now itself deprecated (a likely-sounding corporate bullshit conspiracy explanation is ventured in first link..)

There's a somewhat-active machine fork here: https://github.com/machine-drivers/machine

One suggestion from the "superseded" thread was to use export DOCKER_HOST=ssh://root@example.com, I'm giving that a go now.

$ docker context create swarmssh.autonomic.zone 
  --description "SSH to autonomic swarm" 
  --docker "host=ssh://$USER@swarm.autonomic.zone:222"
Successfully created context "swarmssh.autonomic.zone"
$ docker context use swarmssh.autonomic.zone
$ docker stack ls
...
(remote stacks)

Requires user to be in the docker group.

Certificate set-up was my main draw to docker-machine; I'll close this for now and we can reopen it if it still seems like a good option for the server set-up side.

As of abra/f4798bf:

$ abra context init swarm.autonomic.zone $USER 222
Successfully created context "swarm.autonomic.zone"
$ abra context use swarm.autonomic.zone
Current context is now "swarm.autonomic.zone"
