Implementing a CI/CD Pipeline

Course Duration

3 Days

Audience

Employees of federal, state and local governments; and businesses working with the government.

Prerequisites

Students should understand the purpose of infrastructure servers, be familiar with scripting of any kind, have experience working at the command line in Unix, Linux, or PowerShell, and be comfortable using a text editor.

Course Description

Building, testing, and deploying code can be complex and time-consuming. This three-day, instructor-led, hands-on, technical class provides the solution of how to create an automated CI/CD pipeline that builds, tests, and deploys code every time a developer pushes a code change, ensuring only high-quality and approved code gets deployed. Developers don’t use isolated software tools, so why learn tools in isolation? This course combines the most widely used enterprise technologies into single, integrated, end-to-end pipelines. We’ll teach you git from the ground up so you can securely push code to a remote repository such as Github or Bitbucket. Then we’ll teach you how to configure servers using Ansible from code stored in git. Next, we’ll integrate git and Ansible with Jenkins CI/CD to build, test, and deploy your code into Staging and Production environments, creating an automated end-to-end DevOps pipeline.

• Maintain code using Git and GitHub
• Create, test, and deploy Ansible playbooks through a Jenkins CI/CD pipeline
