OpenShift-Cient Tekton Task

Abstract

The openshift-client Task is the binary for OpenShift CLI that complements kubectl for simplifying deployment and configuration applications on OpenShift.

Usage

Please, consider the usage example below:

---
apiVersion: tekton.dev/v1
kind: PipelineRun
metadata: {}
spec:
  pipelineRef:
    name: task-openshift-client
  params:
    - name: SCRIPT
      value: openShift-CLI-arguments
    - name: VERSION
      value: oc-version

You'll need to replace openShift-CLI-arguments with OpenShift CLI arguments that you want to run and replace oc-version with the version of OpenShift you want to use. 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
manifest_dir true The workspace which contains kubernetes manifests which we want to apply on the cluster.
kubeconfig_dir true The workspace which contains the the kubeconfig file if in case we want to run the oc command on another cluster.

Params

Param Type Default Description
SCRIPT string (required) The OpenShift CLI arguments to run
VERSION string (required) The OpenShift version to use
