Kibana 6.7 cannot connect to elasticsearch

[Mike_H (Mike Hardy)]

Hiya, we're upgrading our elastic stack from 6.6.2 to 6.7.0. The stack is run using the official docker images on Kubernetes.

Elasticsearch upgraded without issue. However, Kibana 6.7.0 cannot connect to Elasticsearch. In fact, it's looking for a totally different url than what we've specified in our yaml.

Request error, retrying HEAD http://elasticsearch:9200/ => getaddrinfo ENOTFOUND elasticsearch elasticsearch:9200

Elasticsearch resides on http://es.default.svc.cluster.local:9200

Per the breaking changes docs, not much has changed.

Aside from the docker image, literally nothing else changed, so I'm not really sure how the URL cannot be found. What could be happening here?

Here's our deployment yaml

Your environment variable should be ELASTICSEARCH_HOSTS.

The elasticsearch.url setting and corresponding ELASTICSEARCH_URL variable was deprecated in 6.6.0.

Huh, guess I missed that. Anyway, that worked - thanks for the assist @nickpeihl!
