How to Install and Run Tekton Pipelines on Kubernetes: A Step‑by‑Step Guide

Hello, I’m Qiao Ke. Starting today I will share a series of articles on Tekton, summarizing my learning and hoping to help anyone interested in Tekton.

Installation

Tekton can be installed easily with the official release files. To install the latest version:

<code>kubectl apply --filename https://storage.googleapis.com/tekton-releases/pipeline/latest/release.yaml</code>

If your environment cannot access the public registry, download the images elsewhere and push them to a private registry.

To install a specific version, e.g.,

v0.32.1

:

<code>kubectl apply -f https://storage.googleapis.com/tekton-releases/pipeline/previous/v0.32.1/release.yaml</code>

Make sure your Kubernetes version is compatible; for example, with Kubernetes 1.19.16 I installed Tekton 0.29.1.

Run Tests

After installation, you can list the Tekton CRDs that were added:

<code># kubectl get crd | grep tekton
clustertasks.tekton.dev               2022-02-28T06:15:38Z
conditions.tekton.dev                2022-02-28T06:15:38Z
extensions.dashboard.tekton.dev      2022-02-28T06:18:40Z
pipelineresources.tekton.dev         2022-02-28T06:15:38Z
pipelineruns.tekton.dev              2022-02-28T06:15:38Z
pipelines.tekton.dev                 2022-02-28T06:15:38Z
runs.tekton.dev                      2022-02-28T06:15:38Z
taskruns.tekton.dev                  2022-02-28T06:15:38Z
tasks.tekton.dev                     2022-02-28T06:15:38Z</code>

And the Tekton pods that are running:

<code># kubectl get po -n tekton-pipelines
NAME                                 READY   STATUS    RESTARTS   AGE
tekton-pipelines-controller-75c456df85-qxvq2   1/1     Running   0          6m57s
tekton-pipelines-webhook-5bc8d6b7c4-w6pdn      1/1     Running   0          8m</code>

Create a simple Task that prints "Hello World!":

<code>apiVersion: tekton.dev/v1beta1
kind: Task
metadata:
  name: hello
spec:
  steps:
  - name: hello
    image: ubuntu
    command:
    - echo
    args:
    - "Hello World!"</code>

Apply the Task:

<code># kubectl apply -f test-task.yaml</code>

Verify the Task exists:

<code># kubectl get task
NAME   AGE
hello  20h</code>

Run the Task with a TaskRun:

<code>apiVersion: tekton.dev/v1beta1
kind: TaskRun
metadata:
  name: hello
spec:
  taskRef:
    name: hello</code>

<code># kubectl apply -f taskrun.yaml</code>

Check the TaskRun status:

<code># kubectl get taskruns.tekton.dev
NAME    SUCCEEDED   REASON      STARTTIME   COMPLETIONTIME
hello   True        Succeeded   41s         26s</code>

Inspect the pod created by the TaskRun and view its logs:

<code># kubectl get po
NAME                READY   STATUS      RESTARTS   AGE
hello-pod-s86lh      0/2     Completed   1          98s

# kubectl logs hello-pod-s86lh
Hello World!</code>

The pod status is

Completed

, similar to a finished Kubernetes Job.

Install Tekton CLI

Download and install the Tekton command‑line tool:

<code>wget https://github.com/tektoncd/cli/releases/download/v0.22.0/tkn_0.22.0_Linux_x86_64.tar.gz
tar xf tkn_0.22.0_Linux_x86_64.tar.gz
mv tkn /usr/local/bin/</code>

After installation, view the help output:

<code># tkn --help

  tkn [flags]
  tkn [command]

Install Tekton Dashboard

Deploy the Tekton Dashboard for a user‑friendly UI:

<code>kubectl apply --filename https://github.com/tektoncd/dashboard/releases/latest/download/tekton-dashboard-release.yaml</code>

After installation, the dashboard UI looks like this:

This article covered the basic installation steps for Tekton, its CLI, and the Dashboard. The official documentation provides more details, and future articles will explore Tekton pipelines, advanced usage, and migration from Jenkins.
