Description

For support ability to register and index Yarnfile, we need a set of REST API to register, search, and recommend applications from application catalog. The proposed API are:

POST /ws/v1/app/register

Register an Application.

GET /ws/v1/app/search?q=[text]

Find application base on search text.

GET /ws/v1/app/recommend

The default list of recommended applications.

The data structure for YARN application looks like this:

{
  "org": "jenkins.org",
  "name": "jenkins",
  "description": "The most popular open source automation server.",
  "icon": "/ws/v1/app/icon/jenkins.png",
  "downloads": 123,
  "likes": 123,
  "services": {
    ...
  }
}

Where services is the Yarn native services object.
