Opa gatekeeper pdb constraint
Use the new PDB rule to make sure that a user can't define a PDB minAvliable bigger then an HPA/deployment number.
I have hit times when OPA admission webhook don't protect against miss configuration: For more info see: https://open-policy-agent.github.io/gatekeeper/website/docs/failing-closed/
It seems like the admisionwebhook isn't perfect, I have created an issue upstream about this: https://github.com/open-policy-agent/gatekeeper-library/issues/279
Lets see if we get any luck
With Azure Policy, we would have to do this in the azure-policy module in a different way.
Closing this as this wasn't solved upstream.
