Overview of this book

The combination of Docker and Jenkins improves your Continuous Delivery pipeline using fewer resources. It also helps you scale up your builds, automate tasks and speed up Jenkins performance with the benefits of Docker containerization. This book will explain the advantages of combining Jenkins and Docker to improve the continuous integration and delivery process of app development. It will start with setting up a Docker server and configuring Jenkins on it. It will then provide steps to build applications on Docker files and integrate them with Jenkins using continuous delivery processes such as continuous integration, automated acceptance testing, and configuration management. Moving on you will learn how to ensure quick application deployment with Docker containers along with scaling Jenkins using Docker Swarm. Next, you will get to know how to deploy applications using Docker images and testing them with Jenkins. By the end of the book, you will be enhancing the DevOps workflow by integrating the functionalities of Docker and Jenkins.

Docker applications

A lot of applications are provided in the form of Docker images that can be downloaded from the internet. If we knew the image name, then it would be enough to run it in the same way we did with the hello world example. How can we find the desired application image on the Docker Hub?

Let's take MongoDB as an example. If we like to find it on the Docker Hub, we have two options:

In the second case, we can perform the following operation:

$ docker search mongo
