Connecting Kibana to multiple Coordinating Nodes in docker-compose setup

[apt-get_install_skil]

Hey,

I am running an Elasticsearch 7.3.0 cluster via docker-compose with 3 machines that host one MDI and one Coordinating-only node each. On one machine I host Kibana as well. I want Kibana to connect to all three coordinating-nodes due to loadbalancing purposes. Therefore I specify in the environment section of the kibana service the following setting:

ELASTICSEARCH_HOSTS: "https://192.168.2.120:9201,https://192.168.2.121:9201,https://192.168.2.122:9201"

However on the startup I get following error message:

FATAL  Error: [elasticsearch.hosts]: types that failed validation:
[elasticsearch.hosts.0]: expected URI with scheme [http|https] but but got [https://192.168.2.120:9201,https://192.168.2.121:9201,https://192.168.2.122:9201].
[elasticsearch.hosts.1]: expected value of type [array] but got [string]

Removing the quotes doesn't solve the issue.

What's the correct way to specify multiple elasticsearch hosts for kibana in a docker-compose file?

Hey @apt-get_install_skil, you'll want to use the following:

ELASTICSEARCH_HOSTS: '["https://192.168.2.120:9201","https://192.168.2.121:9201","https://192.168.2.122:9201"]'

[apt-get_install_skil]

Thanks a lot @Brandon_Kobel! That solved the issue!
