Getting Started with HashiCorp Nomad - Working with Volumes

The video tutorial covers the use of volumes in Nomad, focusing on host and CSI volumes. It explains how host volumes are local to the client and used for stateful workloads, while CSI volumes involve external storage platforms and require more complex configurations. The tutorial provides a step-by-step guide on configuring both types of volumes, highlighting the importance of naming conventions and the role of plugins in managing CSI volumes.

What is a key feature of host volumes in Nomad?

• They are only available for Docker containers.

• They are managed outside of Nomad.

• Nomad is aware of them during scheduling.

• They require a CSI plugin.

Why can't Nomad make scheduling decisions based on Docker volumes?

• Docker volumes are only available on specific clients.

• Docker volumes require a special plugin.

• Docker volumes are managed outside of Nomad.

• Docker volumes are not supported by Nomad.

What is a limitation of host volumes?

• They are stored locally on the client.

• They are not supported by Nomad.

• They require a CSI plugin.

• They can only be used with Java apps.

How does Nomad ensure that a task is scheduled on a client with the required volume?

• By ignoring volume availability.

• By using Docker's default settings.

• By manually configuring each client.

• By using a volume mount parameter as a constraint.

What makes CSI volumes more complex than host volumes?

• They require manual configuration for each client.

• They do not support cloud storage providers.

• They involve drivers, controllers, and external storage platforms.

• They are only available for Docker containers.

Which of the following storage platforms is NOT mentioned as supporting CSI plugins?

• AWS

• Google

• Oracle

• IBM

Which of the following is NOT a step in setting up CSI volumes?

• Registering the volume with Nomad.

• Enabling privileged Docker jobs.

• Configuring each host volume manually.

• Creating the volume on your platform of choice.

What is the purpose of enabling privileged Docker jobs for CSI plugins?

• To simplify the configuration process.

• To support only Kubernetes plugins.

• To enable bidirectional mount propagation.

• To allow Nomad to manage Docker volumes.

What is the final step in deploying applications with CSI volumes?

• Creating a registration file for each volume.

• Deploying the application that consumes the volume.

• Configuring the client agent.

• Running the CSI plugin as a system job.

What is the role of the CSI plugin stanza in the job configuration?

• To specify the Docker image location.

• To connect to external volumes.

• To register the volume with Nomad.

• To indicate a system job.
