this is my policy.yaml file

apiVersion: policy/v1beta1
kind: policy
metadata:
  name: default-deny-egress
  namespace: edna
spec:
  order: 999
  egress:
  - action: deny
    destination:
      net: 35.162.205.100
    source: {}

When I try to apply it I get the following:

error: unable to recognize "app/base/backend/policies/deny-policy.yaml": no matches for kind "policy" in version "v1beta1"

From what I understand you are trying to define a network policy.

In k8s documentation you can find several examples regarding networking policies and every one of these examples is using:

apiVersion: networking.k8s.io/v1
kind: NetworkPolicy

I have also noticed that the yaml file content you provided is not valid. Please refer to the networking policies documentation mentioned earlier or k8s api referece guide for more detailed description of k8s yaml fields.

You should use api/v1beta1 when defining network policies , Also the kind in that case would be NetworkPolicy. I think this is what you should use.

The version policy/v1beta1 is for defining poddisruptionbudget.

The kind Policy is used for defining audit policy and version audit.k8s.io/v1 and since this is not available in your output you cannot use this and hence the error.

Heres a document that might help you.
