Introduction to Nomad

In this lecture, students will learn more about Nomad, why enterprises use it, and why Nomad is a great solution to orchestrate and manage your applications.

Let's talk about all the nomenclature related to Nomad, including jobs, allocations, servers, clients, and lots more.

Learn what a Nomad datacenter looks like and how to architect Nomad to run your applications.

If you're familiar with Kubernetes already, you might find this comparison helps to understand the components of Nomad easier.

In this section, we'll learn how to download and install Nomad.

In this demo, we'll learn how to install Nomad on macOS so you can use the Nomad CLI locally or use Nomad to test configurations and Nomad functionality.

This demo will show you how to install Nomad on a Linux server, such as Amazon Linux or RedHat.

Now that we have Nomad installed, how do we run it as a service or even in development mode? That's what we'll go through in this section.

In this demo, we'll learn how to get things ready to start and run Nomad as a local service.

In the real world, you're not going to run Nomad on a single server or your Macbook, right? So let's learn how to cluster multiple Nomad servers to create a cluster for high availability.

Now that we've talked about forming a cluster, let's see it in action in the lab.

Moving on from servers, this lecture will talk about clients in more detail and why you need them in your Nomad infrastructure.

We've got servers already, now we need to add clients to our cluster so we can ultimately run our workloads.

You've seen how to add nodes to the cluster, but what about removing them? You'll learn how to manage both Nomad servers and clients in this lecture.

Alright, let's see how we manage Nomad servers and clients in the lab.

Unfortunately, Nomad isn't secure by default, so we'll learn how to create a secure Nomad environment in this lecture.

In this lecture, you'll learn why TLS is one of the most important configurations for securing Nomad

Ok, let's secure our cluster using TLS certs on our servers and clients.

Let's discuss why we need to secure gossip encryption within our Nomad cluster.

In this demo, we'll secure the gossip communication in our cluster.

Without ACLs, anybody can modify or change jobs and Nomad configurations, which is why it's important to enable and use Nomad ACLs.

This demo will showcase how to enable, bootstrap, and use the Nomad ACL system.

Learn the different ways that you can interact with your Nomad infrastructure.

In this demo, we'll go through a brief demo using the Nomad CLI.

Nomad includes a UI that can be used to quickly monitor the environment and jobs.

A quick demo to showcase the cool features of the Nomad UI.

Learn more about the Nomad API.

A quick demo to showcase how you can use the Nomad API to make changes to Nomad and submit jobs.

Finally, we're getting into Nomad jobs. Learn more about Nomad jobs in this lecture.

Woah...back up. Before we can jump right in and work with jobs, we need to learn how to write Nomad job specification files.

In this demo, we'll create our first job specification file that we'll use and improve upon throughout the course.

Aww...yeah. Let's learn how to submit jobs to Nomad and launch our applications.

Let's do this....!! In this demo, we'll launch our first Nomad job in our cluster that we've been building throughout the course thus far.

In this lecture, we'll take our Nomad job specification file that we built and continuously improve on it as we learn more and more features of Nomad.

Instructing Nomad where to place our jobs is essential to ensure high availability for your applications. Learn more in this lecture.

This lecture will showcase how to use constraints to restrict the nodes that a job can be scheduled on...

Learn how your Nomad tasks (like apps and containers) communicate on the network so your clients and customers can access your apps.

Thank you so much for completing the course. I truly hope you learned a lot!!! Hope to see you in another course soon!
