Using the Cloud Hosted Elasticsearch with Content Manager

Hey Friends,

I'm just playing around and was wondering if anyone has any quick tips/guides for setting up Content Manager to use the cloud based Elastic Search for indexing.

I have my Elasticsearch Cloud Endpoint setup, I can place that in the Elasticsearch Server URL however I get an error about authentication. 




Which isn't that unexpected as we wouldn't want it unsecure but I'm not sure of what the next steps are. I've had a look a the Elasticsearch Cloud interface and I can create API keys etc. but I'm not sure if that's what I need because there is no where in Enterprise Studio to enter those anyway. 

I know there is X-Pack authentication, is that what I need? 

If you have any tips for me reach out and I can typically figure out any missing pieces. 

Thanks
Peter
