Location: D139/140
Level: Intermediate

Who is this presentation for?

  • Developers, operations engineers, system administrators, and SREs

Materials or downloads needed in advance

  • A laptop with a web browser and an SSH client (Terminal or PuTTY) installed
  • A GitHub account
  • An AWS or Google Cloud Platform account

What you'll learn

  • Learn how to use Nomad to build resilient applications, deploy a cluster scheduler from scratch, and effectively use it to solve software delivery problems
  • Understand how to chaos test your containerized production workloads

Description

Docker and rkt have made it easy to package and ship applications, but running them at scale remains a challenge. And not all organizations have the bandwidth to containerize their workloads.

Anubhav Mishra leads a hands-on dive into Nomad, a single binary cluster scheduler that can be used to build a multiregion, self-healing production environment that runs a diverse set of workloads, including noncontainerized applications. Along the way, Anubhav explores use cases and problems solved by using cluster schedulers and demonstrates why Nomad is designed with operational simplicity and heterogeneous workloads as its core design tenets. Anubhav then spends time destructively testing applications scheduled in Nomad against different types of failures (process failure, machine failure, network connectivity issues, loss of quorum, etc.) and other challenging situations that are likely to happen in a production environment. You’ll gain experience writing and submitting job specifications, interacting with the API, and deployment strategies.

Topics include:

  • Nomad overview and architecture
  • Installing and configuring Nomad
  • Creating, running, and inspecting jobs
  • Service registration
  • Interacting via the HTTP API
  • Advanced job strategies (rolling updates, blue-green deployments)
  • Failure simulation

Hello everyone, I will be provisioning workstations for everyone for this tutorial. So all you will need is a machine with access to SSH and if that isn’t possible, then a shell to the workstations will be accessible via any modern browser!

Thanks and looking forward to seeing y’all tomorrow!

Regards,

Mishra
