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.

Deploying with Chef

Chef is a Ruby-based deployment system from Opscode.

It is pretty easy to try out Chef; for fun, we can do it in a Docker container so we don't pollute our host environment with our experiments:

docker run -it ubuntu

We need the curl command to proceed with downloading the Chef installer:

apt-get -y install curl
curl -L https://www.opscode.com/chef/install.sh | bash

The Chef installer is built with a tool from the Chef team called omnibus. Our aim here is to try out a Chef tool called chef-solo. Verify that the tool is installed:

chef-solo -v

This will give us the following output:

Chef: 12.5.1

The point of chef-solo is to be able to run configuration scripts without the full infrastructure of the configuration system, such as the client/server setup. This type of testing environment is often useful when working with configuration systems, since it can...
