Came here to say this. Nomad is the perfect entry system for getting started with a small cluster for getting to know how container orchestration works and what things to keep in mind when migrating all legacy applications to fit into this type of deployment flow. Nomad allowed us to spin up a 3-worker-node "cluster" with consul in a matter of hours, and it has not needed any maintenance since. With Kubernetes we couldn't even agree on which of the many bootstrapping approaches and scripts-de-jour to use, much less any of the other many decisions that have to be made and will overwhelm you.
