Chapter 2. AdminNetworkPolicy [policy.networking.k8s.io/v1alpha1]

egress

array

Egress is the list of Egress rules to be applied to the selected pods. A total of 100 rules will be allowed in each ANP instance. The relative precedence of egress rules within a single ANP object (all of which share the priority) will be determined by the order in which the rule is written. Thus, a rule that appears at the top of the egress rules would take the highest precedence. ANPs with no egress rules do not affect egress traffic.

Support: Core

egress[]

object

AdminNetworkPolicyEgressRule describes an action to take on a particular set of traffic originating from pods selected by a AdminNetworkPolicy’s Subject field. <network-policy-api:experimental:validation>

ingress

array

Ingress is the list of Ingress rules to be applied to the selected pods. A total of 100 rules will be allowed in each ANP instance. The relative precedence of ingress rules within a single ANP object (all of which share the priority) will be determined by the order in which the rule is written. Thus, a rule that appears at the top of the ingress rules would take the highest precedence. ANPs with no ingress rules do not affect ingress traffic.

Support: Core

ingress[]

object

AdminNetworkPolicyIngressRule describes an action to take on a particular set of traffic destined for pods selected by an AdminNetworkPolicy’s Subject field.

priority

integer

Priority is a value from 0 to 1000. Rules with lower priority values have higher precedence, and are checked before rules with higher priority values. All AdminNetworkPolicy rules have higher precedence than NetworkPolicy or BaselineAdminNetworkPolicy rules The behavior is undefined if two ANP objects have same priority.

Support: Core

subject

object

Subject defines the pods to which this AdminNetworkPolicy applies. Note that host-networked pods are not included in subject selection.

Support: Core

action

string

Action specifies the effect this rule will have on matching traffic. Currently the following actions are supported: Allow: allows the selected traffic (even if it would otherwise have been denied by NetworkPolicy) Deny: denies the selected traffic Pass: instructs the selected traffic to skip any remaining ANP rules, and then pass execution to any NetworkPolicies that select the pod. If the pod is not selected by any NetworkPolicies then execution is passed to any BaselineAdminNetworkPolicies that select the pod.

Support: Core

name

string

Name is an identifier for this rule, that may be no more than 100 characters in length. This field should be used by the implementation to help improve observability, readability and error-reporting for any applied AdminNetworkPolicies.

Support: Core

ports

array

Ports allows for matching traffic based on port and protocols. This field is a list of destination ports for the outgoing egress traffic. If Ports is not set then the rule does not filter traffic via port.

Support: Core

ports[]

object

AdminNetworkPolicyPort describes how to select network ports on pod(s). Exactly one field must be set.

to

array

To is the List of destinations whose traffic this rule applies to. If any AdminNetworkPolicyEgressPeer matches the destination of outgoing traffic then the specified action is applied. This field must be defined and contain at least one item.

Support: Core

to[]

object

AdminNetworkPolicyEgressPeer defines a peer to allow traffic to. Exactly one of the selector pointers must be set for a given peer. If a consumer observes none of its fields are set, they must assume an unknown option has been specified and fail closed.

namedPort

NamedPort selects a port on a pod(s) based on name.

Support: Extended

<network-policy-api:experimental>

portNumber

object

Port selects a port on a pod(s) based on number.

Support: Core

protocol

string

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

Support: Core

end

integer

Support: Core

protocol

string

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

Support: Core

namespaces

object

Namespaces defines a way to select all pods within a set of Namespaces. Note that host-networked pods are not included in this type of peer.

Support: Core

networks

array (string)

Networks defines a way to select peers via CIDR blocks. This is intended for representing entities that live outside the cluster, which can’t be selected by pods, namespaces and nodes peers, but note that cluster-internal traffic will be checked against the rule as well. So if you Allow or Deny traffic to "0.0.0.0/0", that will allow or deny all IPv4 pod-to-pod traffic as well. If you don’t want that, add a rule that Passes all pod traffic before the Networks rule.

Each item in Networks should be provided in the CIDR format and should be IPv4 or IPv6, for example "10.0.0.0/8" or "fd00::/8".

Networks can have upto 25 CIDRs specified.

Support: Extended

Condition contains details for one aspect of the current state of this API Resource. --- This struct is intended for direct use as an array at the field path .status.conditions. For example,

// other fields }

lastTransitionTime is the last time the condition transitioned from one status to another. This should be when the underlying condition changed. If that is not known, then using the time when the API field changed is acceptable.

message

string

message is a human readable message indicating details about the transition. This may be an empty string.

observedGeneration

integer

observedGeneration represents the .metadata.generation that the condition was set based upon. For instance, if .metadata.generation is currently 12, but the .status.conditions[x].observedGeneration is 9, the condition is out of date with respect to the current state of the instance.

reason

reason contains a programmatic identifier indicating the reason for the condition’s last transition. Producers of specific condition types may define expected values and meanings for this field, and whether the values are considered a guaranteed API. The value should be a CamelCase string. This field may not be empty.

status

string

status of the condition, one of True, False, Unknown.

type

string

type of condition in CamelCase or in foo.example.com/CamelCase. --- Many .condition.type values are consistent across resources like Available, but because arbitrary conditions can be useful (see .node.status.conditions), the ability to deconflict is important. The regex it matches is (dns1123SubdomainFmt/)?(qualifiedNameFmt)

dryRun

string

When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed

fieldValidation

string

fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
