Tkn Tekton Task

Abstract

The tkn Task is a binary to perform operations on Tekton resources using tkn.

Usage

Please, consider the usage example below:

---
apiVersion: tekton.dev/v1
kind: PipelineRun
metadata: {}
spec:
  pipelineRef:
    name: task-tkn
  params:
    - name: SCRIPT
      value: "tkn $@"
    - name: ARGS
      value: tkn-command-you-want-to-execute

You'll need to replace tkn-command-you-want-to-execute with tkn CLI arguments based on what operation you want to perform on the Tekton resources. 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.

Workspace

Name Optional Description
kubeconfig_dir true An optional workspace that allows you to provide a .kube/config file for tkn to access the cluster.

Params

Param Type Default Description
SCRIPT string (required) tkn CLI script to execute
ARGS array (required) tkn CLI arguments to run
