Getting Started with HashiCorp Nomad - Demo - Networking

This video tutorial introduces basic networking concepts and demonstrates how to manage Nomad job allocations. It covers checking job status, understanding allocation details, and switching from host to bridge networking mode. The tutorial also explains the installation of CNI plugins necessary for bridge mode and demonstrates running jobs with this configuration.

What command is used to check the status of a Nomad job?

• nomad job inspect

• nomad job view

• nomad job status

• nomad job check

What information can be obtained from the 'nomad alloc status' command?

• Only the allocation ID

• The number of nodes in the cluster

• The node name and logging details

• The job's execution time

What is the default network mode in Nomad?

• Overlay

• Bridge

• None

• Host

Why is it important to have CNI plugins installed when using bridge mode?

• To allow communication between containers

• To enable faster data transfer

• To ensure network isolation

• To prevent job failures

Where should CNI plugins be stored on a Nomad client?

• /etc/nomad/plugins

• /opt/cni/bin

• /usr/local/bin

• /var/lib/nomad

What happens if the required CNI plugins are not present when switching to bridge mode?

• The job will run with limited functionality

• The job will fail with an error

• The job will switch to host mode automatically

• The job will run without network connectivity

What is the benefit of using bridge mode for networking in Nomad?

• It allows for better resource allocation

• It enables communication between containers on the same host

• It reduces network latency

• It simplifies the configuration process
