@systemcraftsman What is this anyway?

@systemcraftsman Tekton is an open source project that provides a framework to create cloud-native CI/CD pipelines quickly. As a Kubernetes-native framework, Tekton makes it easier to deploy across multiple cloud providers or hybrid environments. By leveraging the Custom Resource Definitions (CRDs) in Kubernetes, Tekton uses the Kubernetes control plane to run pipeline tasks. Tekton is one of the initial projects in Continuous Delivery Foundation (CDF) with 25+ members which serves as a governing body for fast-growing CI/CD projects to encourage and sustain vendor-neutral collaboration and participation.

@systemcraftsman Kubernetes-style Pipelines Runs serverless Integrated CI/CD experience (on OpenShift) Use CRDs to define pipelines that run as containers and scale on-demand. Full control over team’s delivery pipelines, plugins and access control with no central CI/CD server to manage. A streamlined user experience through the OpenShift Console developer perspective, CLIs, and IDEs.

@systemcraftsman An application used to create, configure and manage other complex applications Contains domain-specific domain knowledge Operator works based on input from Custom Resource Definitions (CRDs) User describes the desired state Controller applies this state to the application It watches the *desired* state and the *actual* state and makes forward progress to reconcile OperatorHub.io Observe Analyze Act The Operator Pattern

@systemcraftsman Tekton Concepts

@systemcraftsman Tekton Concepts ➔ Task ➔ Pipeline ➔ PipelineRun ➔ TaskRun ➔ PipelineResource

@systemcraftsman Tasks A Task is a collection of sequential steps that run as part of a continuous integration flow. A Task runs in the pod on your cluster. A Task declares: ➔ Inputs ➔ Outputs ➔ Steps

@systemcraftsman Pipeline Resources ➔ Git Resource ➔ Pull Request Resource ➔ Image Resource ➔ Cluster Resource ➔ Storage Resource ➔ Cloud Event Resource
