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

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
