Introducing OpenShift Pipelines

On May 3, 2021, Red Hat released the first public version of OpenShift Pipelines, a cloud-based continuous integration system based on the Tekton open source project . The solution implements the Kubernetes CI / CD framework for developing and executing pipelines, in which each step runs in its own container, allowing steps to scale independently of each other. Today we will take a quick look at the key features and benefits of this solution, as well as provide a list of additional resources for further acquaintance with it and mastering it.

But before moving on to OpenShift Pipelines, let's brush up on the core Tekton concepts.

Basic concepts of Kubernetes-native CI / CD

OpenShift Pipelines augments Kubernetes / OpenShift with appropriate CRDs (User Defined Resources) for CI / CD concepts such as pipeline, task, step. As a result, these concepts become “native” instantiable - they can be created as separate instances and, as a result, fully scaled and deployed, as well as ensure their security using Kubernetes tools.

Therefore, to begin with, let's remember what Tekton concepts are:

Basically, Tekton's core concepts come in two flavors: those that define the pipeline and those that start the pipeline.
