I see the issue here, once i change the server.host, dev config automatically changes to production. how can i put it back to dev settings?

If this is for testing purpose and running as a single node, you can set `discovery.type: single-node` in elasticsearch.yml file while binding to a non-loopback interface. See details at [https://www.elastic.co/guide/en/elasticsearch/reference/current/bootstrap-checks.html#single-node-discovery](https://www.elastic.co/guide/en/elasticsearch/reference/current/bootstrap-checks.html#single-node-discovery)

Please note this is only useful for developement and testing purposes and **not** suitable for production.
