Story

As a user of Cluster Log Forwarding,
I want to rely upon username and password to authenticate against an external Elasticsearch instance.
 

Acceptance Criteria

• Username and passwords are not visible in the configuration as plain text but configured as a Secret
• Integration test that utilizes username and password for the Elasticsearch output
• Username and password is not supported for OpenShift Logging managed Elasticsearch store
• Must work with either HTTP or HTTPs.

Notes

• Modify verification checks to require username and password as a set

Documentation Consideration

• Extend the forwarding to Elasticsearch section with information on how to setup a Secret that contains username and password, and if necessary everything for setting up certificates if HTTPS is being used.
