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.

What steps are taken to remove clients D and E from the cluster?

How many servers and clients are present in the cluster after the expansion?

What is the purpose of marking a client as ineligible?

Describe the process of draining a client in the cluster.

What happens to the allocations of clients D and E after they are marked ineligible?

Explain the significance of the job called 'Tetris I' in the context of the cluster.

What is the final outcome after decommissioning clients D and E?
