Cloud-Native Development - Openshift Pipelines

Transcript

1. Cloud Native Development Getting Started with OpenShift Pipelines Pooja - IBM, Developer Advocate Balaji - Infosys, Principal, Education Training and Assessment
2. https://ibm.biz/cloudnative-gist
3. Cloud native development is about how apps are built and deployed 12 Factor is a methodology for building software Infosys and IBM have world class experience in cloud native development OpenShift is the most ideal platform for application deployment
4. Cloud Native Principles Real-world Use Cases IBM Cloud Native Toolkit Hands-on Lab: Deploy with Tekton Pipelines
5. Cloud native is about how an application is built and deployed, not where it resides.
6. Cloud Native Building Blocks 6 Microservices Automated DevOps Containers Results in a lightweight, modular, highly automated approach
7. Codebase Dependencies Configuration Backing Services Build Release Run Stateless Processes Port Binding Concurrency Disposability Dev Prod Parity Logs Admin Processes 12 Factors

10. • Open source governed by Continuous Delivery Foundation • Contributors from IBM, Google, Red Hat, and more • Cloud-native built upon Kubernetes • Pipelines, Tasks, PipelineRuns, etc. are CRDs • Formerly known as “Knative Build” and “Knative build- pipelines” • Parallel workflows, triggers, every step isolated in a container, etc. • Pipeline-as-code (yaml) • Pipeline portability across clouds and vendors • Trigger on Git commits, pull (merge) requests, webhook, manually, or specific times. • Fostering ecosystem of common pipelines and tasks, e.g. tool integrations, compliance process https://tekton.dev Tekton 10 IBM Cloud / © 2020 IBM Corporation
11. Tekton Concept: Step • The smallest building block • Specify images, commands, arguments • Is a container steps: - name: echo image: ubuntu command: - echo args: - "hello world"
12. Tekton CRD: Task • New CRD • Sequence of Steps • Run in sequential order • Reusable • Perform a specific task • Runs on the same k8s node apiVersion: tekton.dev/v1alpha1 kind: Task metadata: name: echo-hello-world spec: steps: - name: echo image: ubuntu command: - echo args: - "hello world"
13. Tekton CRD: Pipeline • Expresses Tasks • Sequentially • Concurrently • Links input and output • Execute Tasks on different nodes apiVersion: tekton.dev/v1alpha1 kind: Pipeline metadata: name: tutorial-pipeline spec: - name: build-app taskRef: name: build-push resources: outputs: - name: image resource: my-image - name: deploy-app taskRef: name: deploy-kubectl resources: inputs: - name: image resource: my-image from: - build-app
14. Tekton Runtime CRDs • Instances of Pipelines and Tasks: • PipelineRun • TaskRun • Runtime info such as registry information and git repo apiVersion: tekton.dev/v1alpha1 kind: PipelineRun metadata: name: tutorial-pipeline-run-1 spec: serviceAccountName: tutorial-service pipelineRef: name: tutorial-pipeline resources: - name: source-repo resourceRef: name: skaffold-git - name: web-image resourceRef: name: skaffold-image-leeroy-web
15. Putting it all together Linting Unit tests Setup test environment Build images Run integration tests Run end to end tests Publish images Deploy Pipeline Task Task Task Task Task Task Task Step Step Step Step Step Step Step Step Step
