WildFly s2i V2 pipeline

A pipeline to produce an application image using the WildFly s2i builder and runtime image. Image built using Kaniko. The pipeline optionally creates a deployment.

Using minikube v1.25.1, push image to local registry

• minikube start
• minikube addons enable registry
• minikube addons enable registry-aliases

• kubectl apply --filename https://github.com/tektoncd/dashboard/releases/latest/download/tekton-dashboard-release.yaml

Install tasks from catalog

• kubectl apply --filename https://raw.githubusercontent.com/tektoncd/catalog/main/task/git-clone/0.5/git-clone.yaml
• kubectl apply --filename https://raw.githubusercontent.com/tektoncd/catalog/main/task/kaniko/0.5/kaniko.yaml
• kubectl apply --filename https://raw.githubusercontent.com/tektoncd/catalog/main/task/kubernetes-actions/0.2/kubernetes-actions.yaml

Install WildFly s2i task and pipeline

• kubectl create --filename wildfly-s2i-build-task.yaml
• kubectl create --filename wildfly-s2i-build-pipeline.yaml

Create PVC (Maven cache and shared data between tasks)

• kubectl create --filename pvc-sources-maven.yaml

Grant all access to user (required to create POD, services and pipelines from event listener).

• kubectl create --filename rbac.yaml

Enable proxy to access to the Tekton dashboard

• kubectl proxy &
• Access to http://localhost:8001/api/v1/namespaces/tekton-pipelines/services/tekton-dashboard:http/proxy/#/namespaces/default/pipelines
• You should see the wildfly-s2i-build-pipeline.

Example 1: Build an image, create a POD and service

• V2 build: kubectl create --filename examples/test-app-build.yaml
• In tekton dashboard you can monitor the started pipeline run (from PipelineRuns ).
• When done, you can access the application: minikube service test-app

Example 2: Build an image from an existing quickstart, create a POD and service

• V2 build with legacy quickstart: kubectl create --filename examples/qs-rest-client-server-build.yaml
• In tekton dashboard you can monitor the started pipeline run (from PipelineRuns ).
• When done, you can access the application: minikube service qs-rest-client-server

Event listener example: Start the pipeline from an external event

Install tekton triggers

• kubectl apply --filename https://storage.googleapis.com/tekton-releases/triggers/latest/release.yaml
• kubectl apply --filename https://storage.googleapis.com/tekton-releases/triggers/latest/interceptors.yaml

Create the Event listener (a service named el-my-listener is created)

• kubectl apply --filename listener-demo/event-listener.yaml
• kubectl apply --filename listener-demo/pipeline-template.yaml
• Enable port forwarding to send event to the listener: kubectl port-forward service/el-my-listener 8080 &

Send the event

• curl -X POST --data {} 127.0.0.1:8080
• In the tekton dashboard, a new pipeline run is started, you can monitor its state.
