-### Network policies
-
-Network policies can only take effect, when the used CNI plugin support network policies. The chart supports no custom
-network policy implementation of CNI plugins. It's support only the official API resource of `networking.k8s.io/v1`.
-
-The object networkPolicies can contains multiple networkPolicy definitions. There is currently only one example
-predefined - it's named `default`. Further networkPolicy rules can easy be added by defining additional objects. For example:
-
-> [!NOTE]
-> The structure of each custom network policy must be equal like that of default. For this reason don't forget to define
-> `annotations`, `labels` and the other properties as well.
-
-```yaml
-networkPolicies:
-  enabled: false
-  default: {}
-  my-custom-network-policy: {}
-```
-
-The example below is an excerpt of the `values.yaml` file. The network policy `default` contains ingress rules to allow
-incoming traffic from Prometheus. Additionally two egress rules are defined, to allow the application outgoing access to
-the internal running DNS server `core-dns` and the external running postgres database listen on `10.14.243.12`.
-
-> [!IMPORTANT]
-> Please keep in mind, that the namespace and pod selector labels can be different from environment to environment. For
-> this reason, there is are not default network policy rules defined.
