Hi ,  
I am trying to create SAML SSO authentication and secure elk with TLS/SSL on kubernetes . Following the [post](https://blogs.msdn.microsoft.com/atverma/2018/10/09/azure-kubernetes-service-aks-azure-ad-saml-based-single-sign-on-to-secure-elasticsearch-and-kibana-and-securing-communications-in-elk/).

Kibana is unable to connect to elasticsearch. I could successfully deploy elasticsearch with x-pack tls/ssl . Querying the [https://localhost:9200](https://localhost:9200) gives me

```
{

```

"cluster\_name" : "sample-elasticsearch-cluster",  
"cluster\_uuid" : "Ec7pRhtkQKCHOFFBwp5H\_w",

},  
"tagline" : "You Know, for Search"  
}

When i try to query [https://locahost:5601](https://locahost:5601) for kibana i get "kibana server is not ready". Part of the logs shows as below

Thanks very much for your interest in Elasticsearch.

Please be patient in waiting for responses to your question and refrain from pinging multiple times asking for a response or opening multiple topics for the same question. This is a community forum, it may take time for someone to reply to your question and only 16hrs had passed when you asked for an update. For more information please refer to the [Community Code of Conduct](https://www.elastic.co/community/codeofconduct) specifically the section "Be patient".

If you are in need of a service with an SLA that covers response times for questions then you may want to consider talking to us about a [subscription](https://www.elastic.co/subscriptions).

Also, please don't post unformatted code, logs, or configuration as it's very hard to read.

Instead, paste the text and format it with \</\> icon or pairs of triple backticks (```), and check the preview window to make sure it's properly formatted before posting it. This makes it more likely that your question will receive a useful answer.

It would be great if you could update your post to solve this.

</div>

You connect to `https://localhost:9200` but you configure kibana to connect to `https://sample-elasticsearch:9200`, so the fact that you can access the former doesn't help much in this case.

- Is `sample-elasticsearch` on port 9200 resolvable and reachable from within the kibana container ?
- Any errors shown in the elasticsearch logs ?

Elasticsearch has no error logs . I can help you with any logs if required

We have a old ELK setup which is in production . The kibana.yaml has entry for elasticsearch as "[http://elasticsearch-svc.elasticsearch.svc.cluster.local:9200](http://elasticsearch-svc.elasticsearch.svc.cluster.local:9200)" . Strangely kibana.yml is not mounted to the kibana container but still kibana has no issue talking to elasticsearch

Ok, so the problem is that you have configured Kibana to connect to `https://sample-elasticsearch:9200` but this hostname can't be resolved from within the Kibana container.

I unfortunately cannot help you much with your kubernetes setup, but you need to figure out as which host is elasticsearch available from the kibana container and use that hostname in

```auto
elasticsearch.url: https://<the_hostname_here>:9200

```

As an aside, have you looked into [ECK](https://www.elastic.co/products/elastic-cloud-kubernetes), instead of managing your k8s yourself ?
