This chapter covers

Running multiple containers with Docker and Docker Swarm
Modifying Docker Compose files to run on Docker Swarm
Running multiple containers with HashiCorp Nomad
Using Nomad’s built-in user interface to manage container jobs

A key goal of this book is to help you adopt using containers as your go-to-deployment strategy with any given application. We have seen that Kubernetes is an effective way to run and manage containers in production. While I tend to think that Kubernetes is valuable for projects of all sizes, it can be useful to understand a few outstanding alternatives: Docker Swarm and HashiCorp Nomad.

Docker Swarm is essentially Docker Compose distributed across a cluster of ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
