Introduction 

Currently CDAP has Authentication feature for Standalone and Distributed deployments. Up until now there was no such functionality in CDAP running on Kubernetes. This feature is about bringing this capability in so that all deployments have Authentication feature available for the users.

Goals

Enable Authentication capability for CDAP on Kubernetes deployment.

User Stories 

  • As an engineer I want to be able to configure CDAP on Kubernetes with enabled Authentication so that I can make my deployment secure.

Design

Cover details on assumptions made, design alternatives considered, high level design

Description

Changes on CDAP repository

Introduce a new class similar to one of the *ServiceMain classes (any class that extends from the AbstractServiceMain class) for starting the Authentication server. The code is very similar to the AuthenticationServerMain class, except the differences in Guice bindings and added dependency on Zookeeper for secret key propagation. Update RouterServiceMain class to depend on Zookeeper for access to the secret key and use distributed Security module when security is enabled.

Changes on CDAP Operator repository

An update to the CDAP operator https://github.com/cdapio/cdap-operator to introduce a new optional Authentication service, similar to the "Runtime" service.
