[BUG] Unable to configure tls, Pods not created

[sfisli]

What is the bug?

i'am trying to configure tls for opensearch operator, i followed the steps mentioned on the docs but the pods are not created ! and when i see controller logs there's nothing ( if i delete security:http section it works normally)

What is the expected behavior?

Cluster up and running with tls

Do you have any screenshots?

Hi @sfisli Can you please check the logs of the operator if it is reporting anything (make sure to check the operator-controller-manager container)? There will likely be a log line about an error or something the operator is waiting for. I tried applying your config on a local cluster, and aside from the secret having an illegal value (illegal base64 data at input byte 9) pods are being started.

@swoehrl-mw now i got new error when i tried to configure certif with cert-manager and let'sencrypt: opensearch-node-0: [2024-04-22T15:17:51,121][ERROR][o.o.s.c.ConfigurationLoaderSecurity7] [adeiz-opensearch-cluster-nodes-0] Failure no such index [.opendistro_security] retrieving configuration for [INTERNALUSERS, ACTIONGROUPS, CONFIG, ROLES, ROLESMAPPING, TENANTS, NODESDN, WHITELIST, ALLOWLIST, AUDIT] (index=.opendistro_security)

did u fix it ?

[sfisli]

the second issue ? not yet.

@sfisli From the little information you've provided its impossible to tell what is happening. You'll need to check the logs of the securityconfig-update job if it has successfully run. And if not, check the operator logs if it is reporting any problems.

Also: You will need a cluster with at least 3 replicas, anything less is not supported by the operator and can lead to non-functioning clusters.
