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...

Public-key cryptography involves a key pair: a public key and a private key. Each entity has their own. The public key can be shared around, the private key is secret.
