Tekton

Bootstrap Tekton Pipelines and Pipeline Runs for local testing.

Make sure you have some way of running K8s locally:

• Kind
• Minikube

Setup

Install Tekton: https://tekton.dev/docs/installation/pipelines/

# Example
kubectl apply --filename https://storage.googleapis.com/tekton-releases/pipeline/latest/release.yaml

Wait till everything is ready:

kubectl wait --for=condition=Ready pods --all -n tekton-pipelines --timeout=300s

Apply manifest.yml

kubectl apply -f https://raw.githubusercontent.com/redhat-appstudio/rhtap-backstage-plugins/refs/heads/main/development/configuration/tekton/manifest.yml

Ensure that you have pipelines and pipeline runs listed

# List pipelines
tkn p list -n tekton-pipelines

# List pipeline runs
tkn pr list -n tekton-pipelines

Configuring RHDH

NOTE: This repo already has default configs you can use in RHDH: configs.

App config

Fetch the K8s server URL and Service Account token for your RHDH configuration:

# Server URL
kubectl config view -o jsonpath='{.clusters[0].cluster.server}'

# SA token, decoded
kubectl get secret backstage-tekton-token -n tekton-pipelines -o jsonpath='{.data.token}' | base64 -d

In your plugin's app-config.local.yaml file (create one if it doesn't exist) add the following:

kubernetes:
  # see https://backstage.io/docs/features/kubernetes/configuration for kubernetes configuration options
  serviceLocatorMethod:
    type: 'singleTenant'
  clusterLocatorMethods:
    - type: 'config'
      clusters:
        - name: rhtap
          authProvider: serviceAccount
          # kubectl config view -o jsonpath='{.clusters[0].cluster.server}'
          url: <k8s-server-url>
          # kubectl get secret backstage-tekton-token -n tekton-pipelines -o jsonpath='{.data.token}' | base64 --decode
          serviceAccountToken: <service-account-token>
          skipTLSVerify: true
          skipMetricsLookup: true
          customResources:
            - group: tekton.dev
              apiVersion: v1
              plural: pipelineruns
            - group: tekton.dev
              apiVersion: v1
              plural: taskruns
