Why Docker Swarm?

Pop quiz, hotshot.. There's a server with containers on it. Once you run enough containers, you start to loose track of compose files / data. If the host fails, all your services are unavailable. What do you do? WHAT DO YOU DO?1

You too, action-geek, can save the day, by...

  1. Enable Docker Swarm mode (even just on one node)2
  2. Store your swarm configuration and application data in an orderly and consistent structure
  3. Expose all your services consistently using Traefik with optional additional per-service authentication

Then you can really level-up your geek-fu, by:

  1. Making your Docker Swarm highly with keepalived
  2. Setup shared storage to eliminate SPOFs
  3. Backup your stuff automatically
