How to deploy the opensearch kubernates cluster with different roles individually like master, data & client pods #521

Open ganilmca opened 8 months ago

ganilmca commented 8 months ago

Hi Team,

We want to deploy the opensearch cluster with different roles like master, data & clients pods in opensearch-2.11.0 version, but in the below link "https://github.com/opensearch-project/helm-charts/tree/main/charts/opensearch" we can able to deploy the all roles together in each pod. In my cluster we want to deploy the from 20 to 30 pods in this case all pods are master, data & clients pods roles. Is it recommended for maintain all pods as master+data pods in kubernates cluster? If we want to deploy the cluster with different roles then what are the required changes done from my end in above helm charts.

Please help us to resolve this issue.

Thanks, Anil

You need to do multiple installations of the helm chart into the same namespace. Pods from each install will join a single Opensearch cluster. There's a blog post describing this here, but this info should probably be added to the docs too.

Hi @smlx,

Thank you for updating me, but this link not working as expected even we have tried as mentioned the link. We have updated the master helm charts like below. image

If we used like this the cluster was not forming, have got the below error while trying to get cluster health [opensearch@opensearch-cluster-master-0 tools]$ curl -ku admin:Mwpes@1234 -XGET https://localhost:9200/_cluster/health?pretty OpenSearch Security not initialized.[opensearch@opensearch-cluster-master-0 tools]$

The link which you provide here it was working for opensearch-1.x but here we want to deploy for opensearch-2.12.0 which is the latest version.

Can you please confirm is it work for latest version of OpenSearch or not by testing from your side, if it is possible?.

Thanks, Anil
