Integrate with Docker 1.12

Docker 1.12

Docker Swarm

We need to do multiple things to support Docker swarm.

• have the right IP for the manager (+ tracker)
• have a hosts file containing ips of all workers
• We need to have pssh and docker 1.12 installed on the vms
• Check that Ips are passed along right
• have a private key on the manager
• create a data volume on vms
