TektonCD: A Kubernetes-native pipeline resource

https://kurtmadel.com/posts/cicd-with-kubernetes/tekton-standardizing-native-kubernetes-cd/

• Part of CD foundation https://cd.foundation
• Golang
• Run on Kubernetes, k8s - first class citizen
• Apache-2.0 license
• Concepts:
  • Task - (k8s resource) work to be executed. Individually, or part of Pipeline
    • Runs as a Pod in k8s cluster
    • Each step in a separate container
  • TaskRun - (k8s resource) runs the Task
    • kubectl get taskruns/mytask -o yaml - to get results
  • PipelineResources - to define resources to be passed in/out of a task
    • types: git, image, cluster, storage
    • all the resources are used in tasks
  • Pipeline - list of tasks to execute in order
    • previous results could be used as input for the next task
  • PipelineRun - to execute a Pipeline
    • PipelineRun will create TaskRun for the each Tasks
• More features
  • Rich Auth capabilities
  • DAG (directed acyclic graph) of execution
• Roadmap
  • Notifications to Slack, email, Github PR, …
  • Retries
  • Triggers
• IMHO
  • Good basement for a rich CD systems
  • Can’t be used by itself
  • Jenkins X Pipelines uses Tekton
