- Modify VerifyUnmarshalStrict to use serializer/json instead
of sigs.k8s.io/yaml. In strict mode, the serializers
in serializer/json use the new sigs.k8s.io/json library
that also catches case sensitive errors for field names -
e.g. foo vs Foo. Include test case for that in strict/testdata.
- Move the hardcoded schemes to check to the side of the
caller - i.e. accept a slice of runtime.Scheme.
- Move the klog warnings outside of VerifyUnmarshalStrict
and make them the responsibility of the caller.
- Call VerifyUnmarshalStrict when downloading the configuration
from kubeadm-config or the kube-proxy or kubelet-config CMs.
This validation is useful if the user has manually patched the CMs.
