Problem using policy configMap mounted as folder

[ralgozino]

Hello Gareth!

I'm having an strange issue with the plugin that is not happening with the conftest cli. When I try to use a policy package mounted from a kubernetes configMap into a folder I get errors saying that a rule definition is duplicated (I don't think the specific error is important), but if I copy the folder from other location to a new folder and point the flag --policy to that folder the plugin works.

If I mount the same confiMap to the same path but I use conftest instead of the helm plugin I don't encounter the problem.

I think that the policy configmap being mounted as a folder that ends up with symbolic links could be the source of the problem. This could be related: open-policy-agent/opa#782

Is the helm plugin using the same backend as the CLI?

Thank you for your work!
