Getting Started with HashiCorp Nomad - Nomad Clients

The video tutorial explains the role and configuration of Nomad clients within a cluster. It covers the responsibilities of clients, such as executing tasks and jobs, and the importance of having multiple clients for high availability. The tutorial also discusses the architecture of a Nomad data center, including server-client communication using RPC and Raft protocols. It provides details on client configuration, prerequisites for running workloads, and a practical lab setup for adding clients to a Nomad cluster.

• SMTP

What must be installed on Nomad clients to run Docker containers?

• Kubernetes

• Nginx

• Apache

• Docker

What is a key difference between server and client configuration in Nomad?

• Clients do not use Raft protocol

• Clients use HTTP for communication
