NetworkPolicyIngressRule

io.k8s.api.networking.v1.NetworkPolicyIngressRule source ↗

NetworkPolicyIngressRule describes a particular set of traffic that is allowed to the pods matched by a NetworkPolicySpec's podSelector. The traffic must match both ports and from.

from[]NetworkPolicyPeerfrom is a list of sources which should be able to access the pods selected for this rule. Items in this list are combined using a logical OR operation. If this field is empty or missing, this rule matches all sources (traffic not restricted by source). If this field is present and contains at least one item, this rule allows traffic only if the traffic matches at least one item in the from list.
ipBlockIPBlockipBlock defines policy on a particular IPBlock. If this field is set then neither of the other fields can be.
cidrstring requiredcidr is a string representing the IPBlock Valid examples are "192.168.1.0/24" or "2001:db8::/64"
except[]stringexcept is a slice of CIDRs that should not be included within an IPBlock Valid examples are "192.168.1.0/24" or "2001:db8::/64" Except values will be rejected if they are outside the cidr range
namespaceSelectorLabelSelectornamespaceSelector selects namespaces using cluster-scoped labels. This field follows standard label selector semantics; if present but empty, it selects all namespaces.If podSelector is also set, then the NetworkPolicyPeer as a whole selects the pods matching podSelector in the namespaces selected by namespaceSelector. Otherwise it selects all pods in the namespaces selected by namespaceSelector.
matchExpressions[]LabelSelectorRequirementmatchExpressions is a list of label selector requirements. The requirements are ANDed.
keystring requiredkey is the label key that the selector applies to.
operatorstring requiredoperator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.
values[]stringvalues is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch.
matchLabelsmap[string]stringmatchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is "key", the operator is "In", and the values array contains only "value". The requirements are ANDed.
podSelectorLabelSelectorpodSelector is a label selector which selects pods. This field follows standard label selector semantics; if present but empty, it selects all pods.If namespaceSelector is also set, then the NetworkPolicyPeer as a whole selects the pods matching podSelector in the Namespaces selected by NamespaceSelector. Otherwise it selects the pods matching podSelector in the policy's own namespace.
matchExpressions[]LabelSelectorRequirementmatchExpressions is a list of label selector requirements. The requirements are ANDed.
keystring requiredkey is the label key that the selector applies to.
operatorstring requiredoperator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.
values[]stringvalues is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch.
matchLabelsmap[string]stringmatchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is "key", the operator is "In", and the values array contains only "value". The requirements are ANDed.
ports[]NetworkPolicyPortports is a list of ports which should be made accessible on the pods selected for this rule. Each item in this list is combined using a logical OR. If this field is empty or missing, this rule matches all ports (traffic not restricted by port). If this field is present and contains at least one item, then this rule allows traffic only if the traffic matches at least one port in the list.
endPortinteger (int32)endPort indicates that the range of ports from port to endPort if set, inclusive, should be allowed by the policy. This field cannot be defined if the port field is not defined or if the port field is defined as a named (string) port. The endPort must be equal or greater than port.
portIntOrStringport represents the port on the given protocol. This can either be a numerical or named port on a pod. If this field is not provided, this matches all port names and numbers. If present, only traffic on the specified protocol AND port will be matched.
protocolstringprotocol represents the protocol (TCP, UDP, or SCTP) which traffic must match. If not specified, this field defaults to TCP.
