This (and related gists) captures how i created my docker swarm architecture. This is intended mostly for my own notes incase i need to re-creeate anything later! As such expect some typos and possibly even an error...

Installation Step-by-Step

Each major task has its own gist, this is to help with maitainability long term.

1. Install Debian VM for each docker host
2. install Docker
3. Configure Docker Swarm
4. Install Portainer
5. Install KeepaliveD
6. Using VirtioFS backed by CephFS for bind mounts (migrating from glsuterFS - WIP)

	defer resp.Body.Close()

	body, err := ioutil.ReadAll(resp.Body)
