Catalog of shared Tasks and Pipelines.

Tekton Catalog

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.

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 bazel.yaml
task.tekton.dev/bazel created

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

$ kubectl get tasks
NAME    AGE
bazel   3s

OR

$ kubectl get clustertasks
NAME            AGE
cluster-bazel   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/v1alpha1
kind: TaskRun
metadata:
  name: example-run
spec:
  taskRef:
    name: bazel
  inputs:
    params:
    - name: TARGET
      value: //path/to/image:publish
    resources:
    - name: source
      resourceSpec:
        type: git
        params:
        - name: url
          value: https://github.com/my-user/my-repo

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/v1alpha1
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
...
