Welcome to Red Hat Workshop - CI/CD & GitOps

Introduction

Red Hat Workshop CI/CD & GitOps is a repository which includes a tutorial with a set of practices for the purpose of practicing with Kubernetes Native CI/CD pipelines in a GitOps model.

The general idea behind this workshop is to get an initial understanding of the following points:

  • Deploy microservice-based applications in Kubernetes using ArgoCD and Helm

  • Operate applications in Kubernetes using ArgoCD in a GitOps model

  • Implement Kubernetes Native CI/CD Pipelines strategy with Tekton

Getting Started

First of all, it is required to review your local machine prerequisites and laboratory environment access in order to be able to start working on this tutorial.

Please follow Getting Started for more information.

Tutorial Steps

Deployment Workflow

In this step, you will prepare a GitOps repository and deploy Jump App application in Openshift using ArgoCD and Helm.

GitOps Workflow

In this step, you will make a change in your GitOps GitHub repository where application settings are located and then ArgoCD applies this configuration automatically.

CI/CD Workflow

In this step, you will perform a set of tasks in order to understand and implement a CI/CD strategy:

  • Fork a Jump App microservice project in order to be able to make changes in the source code

  • Change some Jump App microservices settings in a GitOps fashion

  • Deploy a CI/CD project in Openshift

  • Configure GitHub to notify your CI/CD project for changes

  • Modify a microservice source code and integrate this new release in a continuous integration & deployment way
