Getting Kibana docker image to connect to ES

[spyderman4g63 (John)]

I have an elasticsearch cluster running in docker using the elastic images. The cluster responds to request from my localhost. I downloaded the kibana docker image and I can't get it to connect to elasticsearch.

I get the following errors:

kibana_1  | {"type":"log","@timestamp":"2020-06-02T15:59:16Z","tags":["warning","elasticsearch","admin"],"pid":7,"message":"Unable to revive connection: http://localhost:9200/"}
kibana_1  | {"type":"log","@timestamp":"2020-06-02T15:59:16Z","tags":["warning","elasticsearch","admin"],"pid":7,"message":"No living connections"}

I've tried http://localhost:9200, http://127.0.0.1:9200, and http://es01:9200 for my elasticsearch_hosts. Here is my yaml:

I tried http://es01:9200 again and it looks like it is working. It looks like that URL is supposed to be a container name.
