I am getting error for this one . @ylasri, above mentioned command is regarding to remote clusters. I am asking the command to disable http on master or data-ingest nodes . Can anyone please answer this one.

Will HTTP enabled by default on all nodes?

5

Why do you want to do this?

This is not possible. The HTTP interface is required on all nodes.

Thanks for replying @DavidTurner. But in the documentation, it has mentioned like, we can disable http . I am refering this document.

The docs you link are for a pretty old version in which the HTTP interface could be disabled. This feature was removed in https://github.com/elastic/elasticsearch/pull/29601.

@DavidTurner, Will it work for 6.8.8 and 6.8.7 versions? . I am not getting any error. But, the pod is not running. I tried disabled it in master pod. When I checked the logs

Yes it works fine in 6.8.x versions.

If you are looking to implement access control, the Security functionality has been free since 6.8/7.1 - https://www.elastic.co/blog/security-for-elasticsearch-is-now-free

Yes, I tried with 6.8.8 for master one , but my pod is not running. I am not getting any error.
elastic-operator-0 1/1 Running 0 19h
elasticsearch-config-es-data-ingest-0 1/1 Running 0 19h
elasticsearch-config-es-master-0 0/1 Running 0 19h

When I described the pod , I am getting as shown below:

Warning Unhealthy 2m51s (x13844 over 19h) kubelet, gke-gtso-enter-gke-g-gtso-enter-gke-g-f4873fba-bexw (combined from similar events): Readiness probe failed: {"timestamp": "2020-09-16T05:20:46+0000", "message": "readiness probe failed", "curl_rc": "7"}
I already pasted logs in above comment. Any one has any idea, why it is like that

Ohh you didn't say you were running in containers. Http is required on all nodes there.
