Getting Started with Tekton: Installation, Task Creation, and Execution on Kubernetes

Tekton is a powerful and flexible Kubernetes‑native open‑source framework for building continuous integration and delivery (CI/CD) systems, abstracting underlying implementation details so users can build, test, and deploy across multiple cloud platforms and on‑premise environments.

Installation steps include logging into an OKD cluster, creating a project, granting the necessary permissions, and applying the latest Tekton release YAML. Example commands are:

oc login -u system:admin

oc new-project tekton-pipelines

oc adm policy add-scc-to-user anyuid -z tekton-pipelines-controller

oc apply --filename https://storage.googleapis.com/tekton-releases/latest/release.yaml

oc get pods --namespace tekton-pipelines --watch

Because the default images are hosted on Google’s registry, pull failures may occur; the guide suggests pulling the images from a personal Docker Hub repository and updating the image names in release.yaml accordingly:

docker pull lizeyang123/tekton-pipeline-webhook:latest

docker pull lizeyang123/tekton-pipeline-controller:latest

Creating a Task involves defining a Task YAML file (e.g., task.yml ) such as:

apiVersion: tekton.dev/v1alpha1

kind: Task

metadata:

name: echo-hello-world

spec:

steps:

- name: echo

image: centos

command:

- echo

args:

- "hello world"

The task is created with oc create -f task.yml .

Running the Task is done by creating a TaskRun YAML (e.g., taskrun.yml ) like:

apiVersion: tekton.dev/v1alpha1

kind: TaskRun

metadata:

name: echo-hello-world-task-run

spec:

taskRef:

name: echo-hello-world

trigger:

type: manual

The TaskRun is launched with oc create -f taskrun.yml and its status can be inspected using oc get taskruns .
