GitOps-Driven CI/CD Workshop on OpenShift with Tekton Pipelines and Quay

Welcome to the GitOps-Driven CI/CD Workshop on OpenShift with Tekton Pipelines and Quay

This workshop aims to introduce participants to the world of GitOps and its applications in continuous integration and continuous deployment (CI/CD) on OpenShift using Tekton pipelines and Quay. The workshop is designed for developers and DevOps engineers with some Kubernetes experience, interested in implementing GitOps principles for CI/CD on OpenShift.

Learning Objectives

By the end of this workshop, participants will be able to:

• Understand the core concepts of GitOps and its benefits for CI/CD

• Learn to implement GitOps workflows on OpenShift using Tekton and Argo CD

• Gain experience managing application deployments through Git repositories

• Integrate Quay into the GitOps pipeline for container image management

Workshop Outline

The workshop will cover the following topics:

1. Introduction to GitOps and OpenShift

   • What is GitOps?

   • Kubernetes management tools: Kustomize, Helm, and Argo CD

   • Why GitOps with OpenShift?

2. Quay and OpenShift GitOps

   • Introduction to Quay

   • Connecting Quay with Argo CD

   • Security considerations for container images in Quay and GitOps

   • Hands-on: Configure Quay integration in your GitOps repository

3. Tekton Pipelines for GitOps

   • Tekton and GitOps

   • Building and pushing images using Tekton

   • Tekton and Argo CD integration

   • Hands-on: Modify Tekton pipelines to work with Argo CD and trigger deployments

4. Deploying the Todo App with GitOps

   • Setting up the GitOps repository

   • Defining the desired state of the application

   • Using Argo CD for deployment

   • Hands-on: Deploy the Todo app using GitOps principles

5. Managing and Updating Applications with GitOps

   • Making changes through Git

   • Automated updates with Argo CD

   • Rollbacks and version control with GitOps

   • Hands-on: Update the Todo app and practice rollbacks using Git and Argo CD

6. Advanced GitOps Techniques (Optional)

   • Progressive delivery: canary deployments and blue/green deployments

   • Multi-environment deployments

   • Observability and monitoring

   • Hands-on: Engage in advanced exercises or demonstrations

Prerequisites

To get the most out of this workshop, participants should have:

• Basic knowledge of Kubernetes and container orchestration

• Familiarity with Git and version control systems

• Access to a local OpenShift cluster or a cloud-based OpenShift deployment

• Tekton and Argo CD installed and configured on your OpenShift cluster
