@alekc the Helm chart refactor PR (#1145) has added annotations using the idiomatic podAnnotations key (it's also added podLabels), hopefully this chart refactor will be released soon. If you need annotations added before then it might be best to use the the podAnnotations key? I haven't added additionalAnnotations to match the additionalLabels value but I could?

@stevehipwell missed your PR. I am ok with closing this one and waiting for yours, but we should still add a specific annotations for both controllers and webhooks (not on the pod level, but the root). Several operators relies on those (i.e. https://github.com/stakater/Reloader) and I don't think there is a reason not to give this flexibility.

@alekc the pods have been merged but I'll add the top level additionalAnnotations and log level.
