Getting Started with HashiCorp Nomad - Demo – Let’s Work with Cluster Members

The video tutorial demonstrates how to manage a cluster by removing clients to save costs. It starts with an overview of the current cluster setup, including servers and clients. The instructor deploys a job using Docker containers and explains how to manage container allocations. Clients D and E are made ineligible for new allocations to reduce costs. The container count is increased, and the allocation changes are observed. Finally, the tutorial shows how to drain allocations from clients D and E and decommission them from the cluster.
