Kibana 7.0.1 does not work on IPv6

Elastic Stack Kibana
1

Hi,
I am using kibana-oss (version - 7.0.1) in kubernetes environment with IPv6 environment.
My kibana.yaml looks like this:

server.name: kibana
server.host: "[::0]"
server.port: 5601
elasticsearch.hosts: "http://elasticsearch:9200"

Kibana pod fails to come up & shows the below error:

`"{ Error: [server.host]: value is [[::0]] but it must be a valid hostname (see RFC 1123).\n    at ObjectType.validate (/usr/share/kibana/node_modules/@kbn/config-schema/target/out/types/type.js:59:19)\n    at ConfigService.createConfig (/usr/share/kibana/src/core/server/config/config_service.js:97:52)\n    at MapSubscriber.getDistinctConfig.pipe.operators_1.map.config [as project] (/usr/share/kibana/src/core/server/config/config_service.js:51:81)\n    at MapSubscriber._next (/usr/share/kibana/node_modules/rxjs/internal/operators/map.js:46:35)\n    at MapSubscriber.Subscriber.next (/usr/share/kibana/node_modules/rxjs/internal/Subscriber.js:64:18)\n    at DistinctUntilChangedSubscriber._next (/usr/share/kibana

I see same error for server.host configured as "[::]", "[::1]".

Can you please tell me the right configuration for this in an IPv6 environment?
Thanks,

@jbudz/@tylersmalley - Can you please tell me the right configuration for kibana server.host parameter in IPv6 environment?

This issue talks about the server not binding to the IPv6 localhost address , but that's a difference use case, you're setting the host to the IPv6 address.

It may be related to this addressing fix which looks like will be part of v7.0.0 of the stack.

I am using kibana-oss-7.0.1. Not sure if the mentioned fix is available in this rpm.
I was able to proceed by configuring "server.host" with the hostname instead of IP address.
