Specification of the desired behavior of Tier.

Tier specifies the tier to which this ClusterNetworkPolicy belongs to. The ClusterNetworkPolicy order will be determined based on the combination of the Tier’s Priority and the ClusterNetworkPolicy’s own Priority. If not specified, this policy will be created in the Application Tier right above the K8s NetworkPolicy which resides at the bottom.

Priority specfies the order of the ClusterNetworkPolicy relative to other AntreaClusterNetworkPolicies.

Select workloads on which the rules will be applied to. Cannot be set in conjunction with AppliedTo in each rule.

Set of ingress rules evaluated based on the order in which they are set. Currently Ingress rule supports setting the From field but not the To field within a Rule.

Set of egress rules evaluated based on the order in which they are set. Currently Egress rule supports setting the To field but not the From field within a Rule.

CIDR is a string representing the IP Block Valid examples are “192.168.1.¹⁄₂₄”.

IPBlock describes the IPAddresses/IPBlocks that is matched in to/from. IPBlock cannot be set as part of the AppliedTo field. Cannot be set with any other selector.

Select Pods from NetworkPolicy’s Namespace as workloads in AppliedTo/To/From fields. If set with NamespaceSelector, Pods are matched from Namespaces matched by the NamespaceSelector. Cannot be set with any other selector except NamespaceSelector.

Select all Pods from Namespaces matched by this selector, as workloads in To/From fields. If set with PodSelector, Pods are matched from Namespaces matched by the NamespaceSelector. Cannot be set with any other selector except PodSelector or ExternalEntitySelector.

Select ExternalEntities from NetworkPolicy’s Namespace as workloads in AppliedTo/To/From fields. If set with NamespaceSelector, ExternalEntities are matched from Namespaces matched by the NamespaceSelector. Cannot be set with any other selector except NamespaceSelector.

Group is the name of the ClusterGroup which can be set as an AppliedTo or within an Ingress or Egress rule in place of a stand-alone selector. A Group cannot be set with any other selector.

The protocol (TCP, UDP, or SCTP) which traffic must match. If not specified, this field defaults to TCP.

The port on the given protocol. This can be either a numerical or named port on a Pod. If this field is not provided, this matches all port names and numbers.

EndPort defines the end of the port range, being the end included within the range. It can only be specified when a numerical port is specified.

Tier specifies the tier to which this NetworkPolicy belongs to. The NetworkPolicy order will be determined based on the combination of the Tier’s Priority and the NetworkPolicy’s own Priority. If not specified, this policy will be created in the Application Tier right above the K8s NetworkPolicy which resides at the bottom.

Priority specfies the order of the NetworkPolicy relative to other NetworkPolicies.

Select workloads on which the rules will be applied to. Cannot be set in conjunction with AppliedTo in each rule.

Set of ingress rules evaluated based on the order in which they are set. Currently Ingress rule supports setting the From field but not the To field within a Rule.

Set of egress rules evaluated based on the order in which they are set. Currently Egress rule supports setting the To field but not the From field within a Rule.
