On Kubernetes 1.7, I am trying to create an ExternalAdmissionHookConfiguration. I have tried to set the failurePolicy: Fail, however, I get the following error:
The ExternalAdmissionHookConfiguration "policy-agent" is invalid: externalAdmissionHooks[0].failurePolicy: Unsupported value: "Fail": supported values: IgnoreThe documentation suggests that Fail is a valid option. https://kubernetes.io/docs/admin/extensible-admission-controllers/
It is valid as of 1.9
I'd recommend building on 1.9 admission webhooks. The pre-1.9 versions were discontinued at alpha level and redone as validating and mutating versions in 1.9
