Content preview from The Docker Book

8 Using the Docker API

In Chapter 6, we saw some excellent examples of how to run services and build applications and workflow around Docker. One of those examples, the TProv application, focused on using the docker binary on the command line and capturing the resulting output. This is not an elegant approach to integrating with Docker; especially when Docker comes with a powerful API you can use to integrate directly.

In this chapter, we’re going to introduce you to the Docker API and see how to make use of it. We’re going to take you through binding the Docker daemon on a network port. We’ll then take you through the API at a high level and hit on the key aspects of it. We’ll also look at the TProv application we saw in Chapter 6 and rewrite ...

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.

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.
