Pipeline Microservices

Use the CDAP Pipeline Microservices to manage data pipelines and connections.

All methods or endpoints described in this API have a base URL (typically http://<host>:11015 or https://<host>:10443) that precedes the resource identifier, as described in the Microservices Conventions. These methods return a status code, as listed in the Microservices Status Codes.

Create or Update a Draft Pipeline

To create or update a pipeline in Draft mode in a namespace, submit an HTTP PUT request:

PUT /v3/namespaces/system/apps/pipeline/services/studio/methods/v1/contexts/<context>/drafts/<draft>

Parameter	Description

Parameter	Description
`context`	The namespace for the Draft pipelines.
`draft`	The Draft ID of the pipeline. The Draft ID can be any alphanumeric string. It must be unique in the namespace.

The request body is a JSON object specifying the name, description, and artifact for the pipeline. There are two supported artifacts for connections: cdap-data-pipeline and cdap-data-streams.

    "artifact": {
      "name": "cdap-data-pipeline",
      "version": "6.3.0-SNAPSHOT",
      "scope": "SYSTEM"
    },
    "config": {<pipeline-config>}
  }
