OPA Gatekeeper rules not taking under BB

Emailed from customer

Hi Eric,

We are running into issues when deploying OPA in conjunction with the Big Bang. It seems that there may be something in the Big Bang configs that is conflicting with our OPA config. For example, when applying the "hostpath deny" policy when using Big Bang, the policy does not apply. This is not an issue when applying the policy on a vanilla cluster. Can you (or someone from your team) give us a hand or point us in the right direction?
