Deploying Tekton

Tekton is the pipeline system we're using for our platform. Originally part of the Knative project for building function-as-a-service on Kubernetes, Tekton has broken out into its own project. The biggest difference between Tekton and other pipeline technologies you may have run is that Tekton is Kubernetes-native. Everything from its execution system, definition, and webhooks for automation are able to run on just about any Kubernetes distribution you can find. For example, we'll be running it in KinD and Red Hat has moved to Tekton as the main pipeline technology used for OpenShift, starting with 4.1.

The process of deploying Tekton is pretty straightforward. Tekton is a series of operators that look for the creation of custom resources that define a build pipeline. The deployment itself only takes a couple of kubectl commands:

$ kubectl create ns tekton-pipelines
$ kubectl create -f chapter14/yaml/tekton-pipelines-policy.yaml
$ kubectl apply ...
