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 was the reason for removing clients D and E from the cluster?

• To test new software

• To increase the number of servers

• To save on costs due to underutilization

• To improve network speed

What was the job deployed across the cluster named?

• Chess

• Tetris

• Pacman

• Snake

How many containers were initially placed across the clients?

• 15

• 10

• 5

• 20

What does making a client 'ineligible' mean in the context of the cluster?

• The client is upgraded

• The client is shut down

• The client cannot receive new allocations

• The client is removed from the network

What was the new desired number of containers after the adjustment?

• 10

• 15

• 20

• 25

What happens to the containers on a client when it is drained?

• They are duplicated

• They are paused

• They are migrated to other clients

• They are deleted

What is the final step after draining the clients of their allocations?

• Decommission the clients

• Add more clients

• Upgrade the clients

• Restart the clients
