Practical DevOps - Second Edition

By: joakim verona

Overview of this book

DevOps is a practical field that focuses on delivering business value as efficiently as possible. DevOps encompasses all code workflows from testing environments to production environments. It stresses cooperation between different roles, and how they can work together more closely, as the roots of the word imply—Development and Operations. Practical DevOps begins with a quick refresher on DevOps and continuous delivery and quickly moves on to show you how DevOps affects software architectures. You'll create a sample enterprise Java application that you’'ll continue to work with through the remaining chapters. Following this, you will explore various code storage and build server options. You will then learn how to test your code with a few tools and deploy your test successfully. In addition to this, you will also see how to monitor code for any anomalies and make sure that it runs as expected. Finally, you will discover how to handle logs and keep track of the issues that affect different processes. By the end of the book, you will be familiar with all the tools needed to deploy, integrate, and deliver efficiently with DevOps.

Continuous Delivery

After the CI steps have completed successfully, you will have shiny new artifacts that are ready to be deployed to servers. Usually, these are test environments set up to behave like production servers. We will discuss deployment system alternatives later in the book.

Often, the last thing a build server does is to deploy the final artifacts from the successful build to an artifact repository. From there, the deployment servers take over the responsibility of deploying them to the application servers. In the Java world, the Nexus repository manager is fairly common. It has support for other formats besides the Java formats, such as JavaScript artifacts and Yum channels for RPMs. Nexus also supports the Docker Registry API now.

Using Nexus for RPM distributions is just one option. You can build Yum channels with a shell script fairly easily.
