Getting Started with HashiCorp Nomad - Demo - Working with Volumes

The video tutorial demonstrates how to configure and validate host volumes in a Nomad environment. It begins with setting up a host volume on Client A and integrating it into a job configuration. The tutorial then expands the setup to Client B, ensuring the host volume is available on multiple clients. Finally, it validates the configuration by running a job and checking the allocations across clients, confirming the host volume's availability.

What is the purpose of adding a host volume in the Nomad setup?

• To increase the network speed

• To store high scores for Tetris

• To enhance security

• To reduce memory usage

Where is the source of the scores volume located?

• In a database

• On a local directory on the client

• In the cloud

• On a remote server

What is the significance of setting 'read only' to false in the configuration?

• It allows the volume to be read-only

• It enables write access to the volume

• It restricts access to the volume

• It encrypts the volume

Why did all allocations initially run on Client A?

• Client A had a higher priority

• Client A was the default client

• The scores volume was only available on Client A

• Client A had more resources

What command is used to create a directory for the host volume on Client B?

• new directory

• sudo mkdir -p

• mkdir -p

• create dir

What must be done after updating the Nomad configuration on Client B?

• Reboot the system

• Update the operating system

• Clear the cache

• Restart the Nomad service

How can you verify that the scores volume is available on Client B?

• By running a Nomad status command

• By checking the network settings

• By inspecting the job logs

• By accessing the UI

What happens when the job is run after setting up the host volume on both clients?

• It runs on both Client A and Client B

• It runs only on Client B

• It runs only on Client A

• It fails to run

What is the purpose of the 'spread' configuration in the job file?

• To reduce the job's memory usage

• To increase the job's priority

• To distribute the job across all nodes

• To limit the job to one client

What command is used to execute into a container to verify the host volume?

• docker exec

• kubectl exec

• nomad exec

• nomad alloc exec
