Practical DevOps

Overview of this book

DevOps is a practical field that focuses on delivering business value as efficiently as possible. DevOps encompasses all the flows from code through testing environments to production environments. It stresses the cooperation between different roles, and how they can work together more closely, as the roots of the word imply—Development and Operations. After a quick refresher to DevOps and continuous delivery, we quickly move on to looking at how DevOps affects architecture. You'll create a sample enterprise Java application that you’ll continue to work with through the remaining chapters. Following this, we explore various code storage and build server options. You will then learn how to perform code testing with a few tools and deploy your test successfully. Next, you will learn how to monitor code for any anomalies and make sure it’s running properly. Finally, you will discover how to handle logs and keep track of the issues that affect processes

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 output as:

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 be hard to get all the bits and pieces in working order while developing the configuration that you are going to deploy.
