Kibana Error Connecting to ES on Docker - Cannot Revive Connection

[chrisruel (CR)]

I am getting an error attempting to connect Kibana to ES using Docker containers:

kibana-products-624 | {"type":"log","@timestamp":"2018-05-25T14:56:36Z","tags":["warning","elasticsearch","admin"],"pid":1,"message":"Unable to revive connection: http://elasticsearch:9200/"}
kibana-products-624 | {"type":"log","@timestamp":"2018-05-25T14:56:36Z","tags":["warning","elasticsearch","admin"],"pid":1,"message":"No living connections"}

I have tried a number of variations in the environment settings and other configuration for the yml, but continue to get this error.

I have verified that ElasticSearch is running and available at port 9200 using CURL and a browser.

What is wrong with this configuration?

Here is the docker-compose.yml:

version: "3"

volumes:
elasticsearch-products-624-vol:

networks:
elasticsearch-net-624:

services:

elasticsearch-products-624-service:

Your Elasticsearch container name is elasticsearch-products-624. Kibana's Elasticsearch URL should match - change to http://elasticsearch-products-624:9200.

Kibana docker image doesn't connect to elasticsearch image

Hi. This one is all about Docker Networking. There are some steps involved in getting Docker to establish network links and name resolution between containers. It's one of the reasons I tend to recommend getting started with Docker Compose, since it takes care of some of these details. The Kibana image tries, by default, to connect to a host/container called elasticsearch. However, the Docker operator must arrange for that name to make sense, and for there to be a network connection between th…

jen-huang - That did fix the connection problem and thanks for the reference. I am working through this to understand exactly this type of connectivity configuration and what each element in the yml actually refers. Too many of the examples just name everything "elasticsearch" and "kibana" and so when I need to build more complex configurations that require different names for different instances, the examples do not make clear what names they actually refer.
Thanks for your help!
