Setup

Create Docker swarm

The generated computational workload is handled by a Docker swarm. A swarm is a group of machines that are running Docker and joined into a cluster. It consists out of two different kinds of members, managers and workers. Currently it is not possible to specify a dedicated Docker host, instead Opaque expects the executing system to be a swarm manager of a swarm with at least one dedicated worker machine. The swarm setup process is described best in the Docker documentation.
