Once installed, +Tekton Pipelines becomes available via the Kubernetes CLI (kubectl) and via API calls, just +like pods and other resources. Tekton is open-source and part of the [CD Foundation](https://cd.foundation/), +a [Linux Foundation](https://www.linuxfoundation.org/projects/) project. + +## Tekton Pipelines entities + +Tekton Pipelines defines the following entities: + +
Entity | +Description | +
---|---|
Task |
+ Defines a series of steps which launch specific build or delivery tools that ingest specific inputs and produce specific outputs. | +
TaskRun |
+ Instantiates a Task for execution with specific inputs, outputs, and execution parameters. Can be invoked on its own or as part of a Pipeline . |
+
Pipeline |
+ Defines a series of Tasks that accomplish a specific build or delivery goal. Can be triggered by an event or invoked from a PipelineRun . |
+
PipelineResource |
+ Defines locations for inputs ingested and outputs produced by the steps in Tasks . |
+
PipelineRun |
+ Instantiates a Pipeline for execution with specific inputs, outputs, and execution parameters. |
