Add Feature to add Sidecar container in Pods

Hello,

Currently, it seems like we are only able to add an initContainer to the deployment but not a sidecar.

We are trying to install a WAF agent that runs as a sidecar container in our pods. We are not able to integrate the sidecar with the current setup and this is blocking us from moving forward.

Could you please let us know when this feature will be added, considering this is a pretty useful feature when you don't want to create a Mutating Webhook Admissions Controller for sidecar injection?

Thanks.
