Modernizing CI/CD with Openshift Pipelines

There are a lot of technologies addressing the needs of CI/CD solutions. However, traditional solutions tend to be rigid and resource hungry. Tekton is a flexible Kubernetes-native open-source CI/CD framework that enables automating deployments across multiple platforms (Kubernetes, serverless, VMs, etc). Tekton aspires to be the common denominator in CI/CD, modeling what Kubernetes has become in Cloud-Native Application development. In this talk, we’ll discuss how it works in practice and why it’s becoming the default CI/CD tool at Openshift Container Platform

8. pen4education Implementation
9. pen4education Pre Reqs 1. Have Tekton or Openshift Pipelines Operator installed 2. What is the platform of your application? Tekton has an Image Builders Catalog- https://cloud.google.com/cloud-build/docs/cloud-builders 3. Tekton CLI: https://github.com/tektoncd/cli
10. pen4education First Step: Secrets Define how to access resources: Source Code and Container registry. apiVersion: v1 kind: Secret metadata: name: basic-user-registry annotations: tekton.dev/docker-0: index.docker.io type: kubernetes.io/basic-auth stringData: username: myuser password: mypassword apiVersion: v1 kind: Secret metadata: name: basic-user-git annotations: tekton.dev/git-0: https://github.com type: kubernetes.io/basic-auth stringData: username: myuser password: mypassword
11. pen4education Second Step: Service Account Define a service account to link previously created secrets. apiVersion: v1 kind: ServiceAccount metadata: name: pipeline namespace: tekton-pipelines secrets: - name: basic-user-registry - name: basic-user-git
12. pen4education Third Step: Pipeline Resource Define resource locations: Source Code and Container registry. apiVersion: tekton.dev/v1alpha1 kind: PipelineResource metadata: name: git-source spec: type: git params: - name: revision value: master - name: url value: https://github.com/myuser/awesome-java-app.git
13. pen4education Third Step: Pipeline Resource apiVersion: tekton.dev/v1alpha1 kind: PipelineResource metadata: name: java-image spec: type: image params: - name: url value: registry.hub.docker.com/myuser/awesome-java-app:1.0
14. pen4education Fourth Step: Tasks Define the parameters, steps and how the pipeline will be executed. apiVersion: tekton.dev/v1alpha1 kind: Task spec: inputs: params: [...] input parameters [...] outputs: [...] output parameters [...] steps: - name: build-and-push image: gcr.io/cloud-builders/mvn command: - mvn - compile
15. pen4education Fifth Step: Pipeline Set of tasks that will be performed in Pipeline apiVersion: tekton.dev/v1alpha1 kind: Pipeline metadata: name: tdc-pipeline spec: resources: [... PipelineResources ...] tasks:[... PipelineResources ...] resources: inputs: [...] input parameters [...] outputs: [...] output parameters [...]
16. pen4education Sixth Step: Pipeline Run apiVersion: tekton.dev/v1alpha1 kind: PipelineRun metadata: name: tdc-pipeline-run spec: pipelineRef: name: tdc-pipeline serviceAccount: pipeline resources: - name: src resourceRef: name: git-source - name: java-image resourceRef: name: java-image-res
