Elasticsearch Installation 8.4

Ankita_Pachauri · September 3, 2022, 1:05pm

Hi Team,
I am trying to install elasticsearch-8.4 version on a centos vm. The steps i followed are:

Java Installation
Creating a repo file
Install Elasticsearch
Start ES

Note: i have not made any changes in yml file. It is a single node.
However after running the below command, I am getting error. Please suggest.

curl --cacert /etc/elasticsearch/certs/http_ca.crt -u elastic https://localhost:9200

Please don't post pictures of text, logs or code. They are difficult to read, impossible to search and replicate (if it's code), and some people may not be even able to see them

Ankita_Pachauri · September 12, 2022, 10:20am

Hi Warkolm,
Apologies for the same.
I am attaching a new issue.
I am installing elk 8.4 on kubernetes and getting a error. Can you please support?

I can't see that anywhere in your config, which is odd?

Ankita_Pachauri · September 12, 2022, 11:10am

Hi Warkolm,
I have used the link helm-charts/values.yaml at main · elastic/helm-charts · GitHub

Can please guide how to fix this?

//Ankita

vincenbr · September 12, 2022, 2:39pm

Hi, apparently you're using an older version (7.x) of the roles specification (with boolean values instead of a list of roles) in your file, and possibly an old version of the Helm chart. Anyway, I am not sure that the helm chart officially supports versions 8.x.
If you are not forced to use helm chart, I really encourage you to look at Kubernetes operator GitHub - elastic/cloud-on-k8s: Elastic Cloud on Kubernetes which works very well.

Ankita_Pachauri · September 12, 2022, 6:05pm

Hi Team,
Can somebody from elastic confirm on the same?

//Ankita

leandrojmp · September 12, 2022, 8:41pm

I'm not sure that the helm charts works with version 8, there is an open issue about it.

The helm charts won't be updated anymore by Elastic, they will focus on the Kubernet Operator, the ECK, but it I'm not sure if they will release a working version for 8.X or not.

Unless someone from the community steps up to maintain the helm charts, the project will not be updated.

warkolm · September 13, 2022, 9:32am

If it's not starting then the logs will give you more information why.
