|
By default, Kubernetes allows communications across all Pods within a cluster.
|
|
The NetworkPolicy resource and a CNI plug-in that supports NetworkPolicy must be used to restrict
|
|
communications. A default NetworkPolicy should be configured for each Namespace to
|
|
default deny all ingress and egress 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. This policy will create a new NetworkPolicy resource
|
|
named `default-deny` which will deny all traffic anytime a new Namespace is created.
