Support for starting sidecar container with opensearch cluster PODs

[ervikrant06]

Hello,

Can anyone pls confirm whether we provide the option of adding sidecar container into the opensearch cluster deployment using operator?

If yes, how can we do it. I checked the CRD couldn't find the option to do it.

Use case:

Want to access the cloud bucket from opensearch deployment in on-prem but it requires dnsmasq hack which we usually do with sidecar container.

Hey :) sidecar is not supported yet, you can declare your own init pod and run additional logic from it. but no, sidecar is still not an option today.

You are more than welcome to raise a PR on it, should be pretty simple. Thanks !

I also need this feature to supply for instance a otel-collector as sidecar for the otel-telemetry plugin using the otel metric exporter.
