Kibana Error Connecting to ElasticSearch using Docker - Cannot Revive Connection

Question

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"

elasticsearch-products-624-vol:

networks:
elasticsearch-net-624:

Answer 1

ELASTICSEARCH_URL = http：// elasticsearch ：9200应更改为：ELASTICSEARCH_URL = http：// elasticsearch -products-624：9200以引用上面实例化的容器。
