policies.kyverno.io/description: By default, Kubernetes allows communications across
|
|
all pods within a cluster. Network policies and, a CNI that supports network policies,
|
|
must be used to restrict communinications. A default NetworkPolicy should be configured
|
|
for each namespace to default deny all ingress traffic to the pods in the namespace.
|
|
Application teams can then configure additional NetworkPolicy resources to allow
|
|
desired traffic to application pods from select sources.
