are there scenarios where customer may want to set a single per-pod override that will apply to all containers?

Possibly, but I don't have a specific use-case for that right now. I was looking to just build the simplest thing for now; we can always add functionality later if it's desired.

thank you! If there will be a scenario with some global setting for a Pod that will require all containers to adjust limits, it will make sense to have a single override. I am also not aware of scenarios that would need this.

lgtm +1 to add support for rlimits in NRI, it will be helpful for folks who need to configure rlimits in k8s environments where rlimits are not natively supported in pod specs. |
This PR adds support for adjusting rlimits and provides a sample plugin. I was able to test this using a patched version of containerd.
