To get the most out of this book
We will be using Git, Docker, systemd, OpenSSL, NGINX, and other tools on Linux, so you need basic familiarity with the Linux command line. For AWS Jenkins, you need an AWS account where you can create and manage EC2 instances, ELBs, AWS Certificate Manager certificates, and Route 53 entries. For the Jenkins inside a corporate firewall, you need three virtual machines and optionally access to a company Public Key Infrastructure (PKI) where you can generate TLS/SSL certificates. You also need a GitHub and a Docker Hub account.
Software/hardware covered in the book |
Windows, macOS, Linux, or any other operating system that you can use to SSH into a Linux machine |
Ubuntu 20.04 for the virtual machines and EC2 instances |
Docker 18 or higher, used in the Ubuntu 20.04 hosts |
Git and OpenSSL, which are preinstalled in Ubuntu 20.04 |
Jenkins 2.263.1-LTS or higher |
Jenkinsfiles and Shared Libraries code are written in the Groovy programming language. You can follow along without prior experience with Groovy, but familiarity with Groovy will help you understand the shared libraries chapter more easily. It’s very similar to Java.
If you are using the digital version of this book, we advise you to type the code yourself or access the code via the GitHub repository (link available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
