第 4 章 Creating CI/CD solutions for applications using OpenShift Pipelines

With Red Hat OpenShift Pipelines, you can create a customized CI/CD solution to build, test, and deploy your application.

To create a full-fledged, self-serving CI/CD Pipeline for an application, you must perform the following tasks:

Create custom Tasks, or install existing reusable Tasks.
Create and define the delivery Pipeline for your application.
Create a PersistentVolumeClaim attached to the Workspace to provide the volume or filesystem for Pipeline execution.
Create a PipelineRun to instantiate and invoke the Pipeline.
Add Triggers to capture any events in the source repository.

This section uses the pipelines-tutorial example to demonstrate the preceding tasks. The example uses a simple application which consists of:

A front-end interface, vote-ui, with the source code in the ui-repo Git repository.
A back-end interface, vote-api, with the source code in the api-repo Git repository.
The apply_manifest and update-deployment Tasks in the pipelines-tutorial Git repository.

4.1. Prerequisites

You have access to an OpenShift Container Platform cluster.
You have installed OpenShift Pipelines using the Red Hat OpenShift Pipelines Operator listed in the OpenShift OperatorHub. Once installed, it is applicable to the entire cluster.
You have installed OpenShift Pipelines CLI.
You have forked the front-end ui-repo and back-end api-repo Git repositories using your GitHub ID, and have Administrator access to these repositories.
Optional: You have cloned the pipelines-tutorial Git repository.
