Where I can find configuration documentation for docker images for:  
[docker.elastic.co/app-search/app-search:7.5.1](http://docker.elastic.co/app-search/app-search:7.5.1) ? I am not sure how to configure app search docker image to connect to ES within Kubernetes cluster.

I am getting following error on startup:

> Blockquote  
> Error: App Search is unable to connect to Elasticsearch. Ensure a healthy Elasticsearch cluster is running at [http://quickstart-es-default:9200](http://quickstart-es-default:9200) for user elastic.  
> Blockquote

The [http://quickstart-es-default:9200](http://quickstart-es-default:9200) is correct address and I can successfully do following:  
curl -u "elastic:somepassword" -k "[https://quickstart-es-default:9200](https://quickstart-es-default:9200)" from any node in the cluster.

thanks

Solved! Had to configure app search to use ssl (ca, ce, and key).
