Kn Tekton Task

Abstract

The kn Task performs operations on Knative resources (services, revisions, routes) using kn CLI.

Usage

Please, consider the usage example below:

---
apiVersion: tekton.dev/v1
kind: TaskRun
metadata:
  name: example-taskrun
spec:
  taskRef:
    name: kn
  params:
    - name: ARGS
      value:
        - help

Here ARGS param accepts an array of arguments for usage with kn command.

In case the Container Registry requires authentication, please consider the Tekton Pipelines documentation. In a nutshell, you need to create a Kubernetes Secret describing the following attributes:

kubectl create secret docker-registry imagestreams \
  --docker-server="image-registry.openshift-image-registry.svc:5000" \
  --docker-username="${REGISTRY_USERNAME}" \
  --docker-password="${REGISTRY_TOKEN}"

Then make sure the Secret is linked with the Service-Account running the TaskRun/PipelineRun.
