Tekton Catalog

If you want v1alpha1 resources, you need to go to the v1alpha1 branch. The master branch is synced with v1beta1 since 2020, 19th June.

This repository contains a catalog of Task resources (and someday Pipelines and Resources), which are designed to be reusable in many pipelines.

Each Task is provided in a separate directory along with a README.md and a Kubernetes manifest, so you can choose which Tasks to install on your cluster. A directory can hold one task and multiple versions.

See our project roadmap.

Catalog Structure

1. Each resource follows the following structure

   ./task/                     👈 the kind of the resource
   
       /argocd                 👈 definition file must have same name
          /0.1
            /OWNERS            👈 owners of this resource
            /README.md
            /argocd.yaml       👈 the file name should match the resource name
            /samples/deploy-to-k8s.yaml
          /0.2/...
   
       /golang-build
          /OWNERS
          /README.md
          /0.1
            /README.md
            /golang-build.yaml
            /samples/golang-build.yaml
   

2. Resource YAML file includes following changes

• Labels include the version of the resource.
• Annotations include minimum pipeline version supported by the resource, tags associated with the resource and displayName of the resource

 labels:
    app.kubernetes.io/version: "0.1"            👈 Version of the resource

  annotations:
    tekton.dev/pipelines.minVersion: "0.12.1"   👈 Min Version of pipeline resource is compatible
    tekton.dev/tags: "ansible, cli"             👈 Comma separated list of tags
    tekton.dev/displayName: "Ansible Tower Cli" 👈 displayName can be optional

spec:
  description: |-
    ansible-tower-cli task simplifies
    workflow, jobs, manage users...             👈 Summary

Task Kinds

There are two kinds of Tasks:

1. ClusterTask with a Cluster scope, which can be installed by a cluster operator and made available to users in all namespaces
2. Task with a Namespace scope, which is designed to be installed and used only within that namespace.

Tasks in this repo are namespace-scoped Tasks, but can be installed as ClusterTasks by changing the kind.

Using Tasks

First, install a Task onto your cluster:

$ kubectl apply -f golang/build.yaml
task.tekton.dev/golang-build created

You can see which Tasks are installed using kubectl as well:

$ kubectl get tasks
NAME           AGE
golang-build   3s

With the Task installed, you can define a TaskRun that runs that Task, being sure to provide values for required input parameters and resources:

apiVersion: tekton.dev/v1beta1
kind: TaskRun
metadata:
  name: example-run
spec:
  taskRef:
    name: golang-build
  params:
  - name: package
    value: github.com/tektoncd/pipeline
  workspaces:
  - name: source
    persistentVolumeClaim:
      claimName: my-source

Next, create the TaskRun you defined:

$ kubectl apply -f example-run.yaml
taskrun.tekton.dev/example-run created

You can check the status of the TaskRun using kubectl:

$ kubectl get taskrun example-run -oyaml
apiVersion: tekton.dev/v1beta1
kind: TaskRun
metadata:
  name: example-run
spec:
  ...
status:
  completionTime: "2019-04-25T18:10:09Z"
  conditions:
  - lastTransitionTime: "2019-04-25T18:10:09Z"
    status: True
    type: Succeeded
...
