Video description

Nomad, a flexible scheduler and workload orchestrator, enables an organization to deploy and manage any containerized or legacy application easily using a single, unified workflow. Nomad can run a diverse workload of Docker, non-containerized, microservice, and batch applications.

This course begins with an introduction to Nomad’s key features and capabilities, including container orchestration, service discovery, and multi-cloud deployment. You will also learn to install and configure Nomad, set up a cluster, and integrate it with other HashiCorp tools stacks such as Consul and Vault. You will learn to deploy and manage applications on Nomad on different platforms and perform tasks, including scheduling, resource allocation, and rollouts.

We will use the user interface to learn concepts based on our requirements. We will create job specifications and run our first Nomad job. We will manage Nomad and monitor a Nomad environment and application logs. We will create a rotating gossip encryption key and upgrade Nomad to newer versions. We will also explore how to troubleshoot and debug issues that may arise using Nomad in a production environment.

By the end of this course, you will have the skills and knowledge required to use HashiCorp Nomad successfully and use Nomad to automate and streamline your organization’s workflow.
