6 top-level fields, 1 required · last changed in Cilium 1.20.0
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
Spec is the desired Cilium specific rule specification.
Description is a free form string, it can be used by the creator of the rule to store human readable explanation of the purpose of this rule. Rules cannot be identified by comment.
Egress is a list of EgressRule which are enforced at egress. If omitted or empty, this rule does not apply at egress.
Authentication is the required authentication type for the allowed traffic, if any.

Fields is a list of ICMP fields.
Family is a IP address version. Currently, we support `IPv4` and `IPv6`. `IPv4` is set as default.
Type is a ICMP-type. It should be an 8bit code (0-255), or it's CamelCase name (for example, "EchoReply"). Allowed ICMP types are: Ipv4: EchoReply | DestinationUnreachable | Redirect | Echo | EchoRequest | RouterAdvertisement | RouterSelection | TimeExceeded | ParameterProblem | Timestamp | TimestampReply | Photuris | ExtendedEcho Request | ExtendedEcho Reply Ipv6: DestinationUnreachable | PacketTooBig | TimeExceeded | ParameterProblem | EchoRequest | EchoReply | MulticastListenerQuery| MulticastListenerReport | MulticastListenerDone | RouterSolicitation | RouterAdvertisement | NeighborSolicitation | NeighborAdvertisement | RedirectMessage | RouterRenumbering | ICMPNodeInformationQuery | ICMPNodeInformationResponse | InverseNeighborDiscoverySolicitation | InverseNeighborDiscoveryAdvertisement | HomeAgentAddressDiscoveryRequest | HomeAgentAddressDiscoveryReply | MobilePrefixSolicitation | MobilePrefixAdvertisement | DuplicateAddressRequestCodeSuffix | DuplicateAddressConfirmationCodeSuffix | ExtendedEchoRequest | ExtendedEchoReply
ToCIDR is a list of IP blocks which the endpoint subject to the rule is allowed to initiate connections. Only connections destined for outside of the cluster and not targeting the host will be subject to CIDR rules. This will match on the destination IP address of outgoing connections. Adding a prefix into ToCIDR or into ToCIDRSet with no ExcludeCIDRs is equivalent. Overlaps are allowed between ToCIDR and ToCIDRSet. Example: Any endpoint with the label "app=database-proxy" is allowed to initiate connections to 10.2.3.0/24
ToCIDRSet is a list of IP blocks which the endpoint subject to the rule is allowed to initiate connections to in addition to connections which are allowed via ToEndpoints, along with a list of subnets contained within their corresponding IP block to which traffic should not be allowed. This will match on the destination IP address of outgoing connections. Adding a prefix into ToCIDR or into ToCIDRSet with no ExcludeCIDRs is equivalent. Overlaps are allowed between ToCIDR and ToCIDRSet. Example: Any endpoint with the label "app=database-proxy" is allowed to initiate connections to 10.2.3.0/24 except from IPs in subnet 10.2.3.0/28.
CIDR is a CIDR prefix / IP Block.
CIDRGroupRef is a reference to a CiliumCIDRGroup object. A CiliumCIDRGroup contains a list of CIDRs that the endpoint, subject to the rule, can (Ingress/Egress) or cannot (IngressDeny/EgressDeny) receive connections from.
CIDRGroupSelector selects CiliumCIDRGroups by their labels, rather than by name.
matchExpressions is a list of label selector requirements. The requirements are ANDed.
key is the label key that the selector applies to.
operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.
values 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.
matchLabels 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.
ExceptCIDRs is a list of IP blocks which the endpoint subject to the rule is not allowed to initiate connections to. These CIDR prefixes should be contained within Cidr, using ExceptCIDRs together with CIDRGroupRef is not supported yet. These exceptions are only applied to the Cidr in this CIDRRule, and do not apply to any other CIDR prefixes in any other CIDRRules.
ToEndpoints is a list of endpoints identified by an EndpointSelector to which the endpoints subject to the rule are allowed to communicate. Example: Any endpoint with the label "role=frontend" can communicate with any endpoint carrying the label "role=backend". Note that while an empty non-nil ToEndpoints does not select anything, nil ToEndpoints is implicitly treated as a wildcard selector if ToPorts are also specified. To select everything, use one EndpointSelector without any match requirements.
matchExpressions is a list of label selector requirements. The requirements are ANDed.
key is the label key that the selector applies to.
operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.

ToFQDN allows whitelisting DNS names in place of IPs. The IPs that result from DNS resolution of `ToFQDN.MatchName`s are added to the same EgressRule object as ToCIDRSet entries, and behave accordingly. Any L4 and L7 rules within this EgressRule will also apply to these IPs. The DNS -> IP mapping is re-resolved periodically from within the cilium-agent, and the IPs in the DNS response are effected in the policy for selected pods as-is (i.e. the list of IPs is not modified in any way). Note: An explicit rule to allow for DNS traffic is needed for the pods, as ToFQDN counts as an egress rule and will enforce egress policy when PolicyEnforcment=default. Note: If the resolved IPs are IPs within the kubernetes cluster, the ToFQDN rule will not apply to that IP. Note: ToFQDN cannot occur in the same policy as other To* rules.
MatchName matches literal DNS names. A trailing "." is automatically added when missing.
MatchPattern allows using wildcards to match DNS names. All wildcards are case insensitive. The wildcards are: - "*" matches 0 or more DNS valid characters, and may occur anywhere in the pattern. As a special case a "*" as the leftmost character, without a following "." matches all subdomains as well as the name to the right. A trailing "." is automatically added when missing. - "**." is a special prefix which matches all multilevel subdomains in the prefix. Examples: 1. `*.cilium.io` matches subdomains of cilium at that level www.cilium.io and blog.cilium.io match, cilium.io and google.com do not 2. `*cilium.io` matches cilium.io and all subdomains ends with "cilium.io" except those containing "." separator, subcilium.io and sub-cilium.io match, www.cilium.io and blog.cilium.io does not 3. `sub*.cilium.io` matches subdomains of cilium where the subdomain component begins with "sub". sub.cilium.io and subdomain.cilium.io match while www.cilium.io, blog.cilium.io, cilium.io and google.com do not 4. `**.cilium.io` matches all multilevel subdomains of cilium.io. "app.cilium.io" and "test.app.cilium.io" match but not "cilium.io"
ToGroups allows policies to reference CIDRs provided by external integrations. Currently, only AWS is supported, and the rule can select by multiple sub directives. ToGroups entries are functionally equivalent to toCIDR, and have the same limitiations. They cannot select traffic originating from within the cluster. Example: toGroups: - aws: securityGroupsIds: - 'sg-XXXXXXXXXXXXX'

EnvoyConfig is a reference to the CEC or CCEC resource in which the listener is defined.
Kind is the resource type being referred to. Defaults to CiliumEnvoyConfig or CiliumClusterwideEnvoyConfig for CiliumNetworkPolicy and CiliumClusterwideNetworkPolicy, respectively. The only case this is currently explicitly needed is when referring to a CiliumClusterwideEnvoyConfig from CiliumNetworkPolicy, as using a namespaced listener from a cluster scoped policy is not allowed.
Name is the resource name of the CiliumEnvoyConfig or CiliumClusterwideEnvoyConfig where the listener is defined in.
Name is the name of the listener.
Priority for this Listener that is used when multiple rules would apply different listeners to a policy map entry. Behavior of this is implementation dependent.

Accepted values: "TCP", "UDP", "SCTP", "VRRP", "IGMP", "GRE", "IPIP", "IPV6", "ESP", "AH", "ANY" Tunnel/encapsulation protocols (GRE, IPIP, IPV6, ESP, AH) and other extended IP protocols (VRRP, IGMP) require the --enable-extended-ip-protocols flag to be set. These protocols do not use transport-layer ports. Matching on ICMP is not supported. Named port specified for a container may narrow this down, but may not contradict this.
Rules is a list of additional port level rules which must be met in order for the PortRule to allow the traffic. If omitted or empty, no layer 7 rules are enforced.

Mismatch identifies what to do in case there is no match. The default is to drop the request. Otherwise the overall rule is still considered as matching, but the mismatches are logged in the access log.
Name identifies the header.
Secret refers to a secret that contains the value to be matched against. The secret must only contain one entry. If the referred secret does not exist, and there is no "Value" specified, the match will fail.
Name is the name of the secret.

EnableDefaultDeny determines whether this policy configures the subject endpoint(s) to have a default deny mode. If enabled, this causes all traffic not explicitly allowed by a network policy to be dropped. If not specified, the default is true for each traffic direction that has rules, and false otherwise. For example, if a policy only has Ingress or IngressDeny rules, then the default for ingress is true and egress is false. If multiple policies apply to an endpoint, that endpoint's default deny will be enabled if any policy requests it. This is useful for creating broad-based network policies that will not cause endpoints to enter default-deny mode.

Only connections which do *not* originate from the cluster or from the local host are subject to CIDR rules. In order to allow in-cluster connectivity, use the FromEndpoints field. This will match on the source IP address of incoming connections. Adding a prefix into FromCIDR or into FromCIDRSet with no ExcludeCIDRs is equivalent. Overlaps are allowed between FromCIDR and FromCIDRSet. Example: Any endpoint with the label "app=my-legacy-pet" is allowed to receive connections from 10.3.9.1
FromCIDRSet is a list of IP blocks which the endpoint subject to the rule is allowed to receive connections from in addition to FromEndpoints, along with a list of subnets contained within their corresponding IP block from which traffic should not be allowed. This will match on the source IP address of incoming connections. Adding a prefix into FromCIDR or into FromCIDRSet with no ExcludeCIDRs is equivalent. Overlaps are allowed between FromCIDR and FromCIDRSet.

These protocols do not use transport-layer ports. Matching on ICMP is not supported. Named port specified for a container may narrow this down, but may not contradict this.
Rules is a list of additional port level rules which must be met in order for the PortRule to allow the traffic. If omitted or empty, no layer 7 rules are enforced.
DNS-specific rules.

As a special case a "*" as the leftmost character, without a following "." matches all subdomains as well as the name to the right. A trailing "." is automatically added when missing. - "**." is a special prefix which matches all multilevel subdomains in the prefix. Examples: 1. `*.cilium.io` matches subdomains of cilium at that level www.cilium.io and blog.cilium.io match, cilium.io and google.com do not 2. `*cilium.io` matches cilium.io and all subdomains ends with "cilium.io" except those containing "." separator, subcilium.io and sub-cilium.io match, www.cilium.io and blog.cilium.io does not 3. `sub*.cilium.io` matches subdomains of cilium where the subdomain component begins with "sub". sub.cilium.io and subdomain.cilium.io match while www.cilium.io, blog.cilium.io, cilium.io and google.com do not 4. `**.cilium.io` matches all multilevel subdomains of cilium.io.

Mismatch identifies what to do in case there is no match. The default is to drop the request. Otherwise the overall rule is still considered as matching, but the mismatches are logged in the access log.
Name identifies the header.
Secret refers to a secret that contains the value to be matched against. The secret must only contain one entry. If the referred secret does not exist, and there is no "Value" specified, the match will fail.
Name is the name of the secret.
Namespace is the namespace in which the secret exists. Context of use determines the default value if left out (e.g., "default").
Value matches the exact value of the header. Can be specified either alone or together with "Secret"; will be used as the header value if the secret can not be found in the latter case.
Headers is a list of HTTP headers which must be present in the request. If omitted or empty, requests are allowed regardless of headers present.

TerminatingTLS is the TLS context for the connection terminated by the L7 proxy. For egress policy this specifies the server-side TLS parameters to be applied on the connections originated from the local endpoint and terminated by the L7 proxy. For ingress policy this specifies the server-side TLS parameters to be applied on the connections originated from a remote source and terminated by the L7 proxy.
Certificate is the file name or k8s secret item name for the certificate chain. If omitted, 'tls.crt' is assumed, if it exists. If given, the item must exist.
PrivateKey is the file name or k8s secret item name for the private key matching the certificate chain. If omitted, 'tls.key' is assumed, if it exists. If given, the item must exist.
Secret is the secret that contains the certificates and private key for the TLS context. By default, Cilium will search in this secret for the following items: - 'ca.crt' - Which represents the trusted CA to verify remote source. - 'tls.crt' - Which represents the public key certificate. - 'tls.key' - Which represents the private key matching the public key certificate.
Name is the name of the secret.

Only connections which do *not* originate from the cluster or from the local host are subject to CIDR rules. In order to allow in-cluster connectivity, use the FromEndpoints field. This will match on the source IP address of incoming connections. Adding a prefix into FromCIDR or into FromCIDRSet with no ExcludeCIDRs is equivalent. Overlaps are allowed between FromCIDR and FromCIDRSet. Example: Any endpoint with the label "app=my-legacy-pet" is allowed to receive connections from 10.3.9.1
FromCIDRSet is a list of IP blocks which the endpoint subject to the rule is allowed to receive connections from in addition to FromEndpoints, along with a list of subnets contained within their corresponding IP block from which traffic should not be allowed. This will match on the source IP address of incoming connections. Adding a prefix into FromCIDR or into FromCIDRSet with no ExcludeCIDRs is equivalent. Overlaps are allowed between FromCIDR and FromCIDRSet.

ToFQDN allows whitelisting DNS names in place of IPs. The IPs that result from DNS resolution of `ToFQDN.MatchName`s are added to the same EgressRule object as ToCIDRSet entries, and behave accordingly. Any L4 and L7 rules within this EgressRule will also apply to these IPs. The DNS -> IP mapping is re-resolved periodically from within the cilium-agent, and the IPs in the DNS response are effected in the policy for selected pods as-is (i.e. the list of IPs is not modified in any way). Note: An explicit rule to allow for DNS traffic is needed for the pods, as ToFQDN counts as an egress rule and will enforce egress policy when PolicyEnforcment=default. Note: If the resolved IPs are IPs within the kubernetes cluster, the ToFQDN rule will not apply to that IP. Note: ToFQDN cannot occur in the same policy as other To* rules.
MatchName matches literal DNS names. A trailing "." is automatically added when missing.
MatchPattern allows using wildcards to match DNS names. All wildcards are case insensitive. The wildcards are: - "*" matches 0 or more DNS valid characters, and may occur anywhere in the pattern.

Name is the resource name of the CiliumEnvoyConfig or CiliumClusterwideEnvoyConfig where the listener is defined in.
Name is the name of the listener.
Priority for this Listener that is used when multiple rules would apply different listeners to a policy map entry. Behavior of this is implementation dependent.

EnableDefaultDeny determines whether this policy configures the subject endpoint(s) to have a default deny mode. If enabled, this causes all traffic not explicitly allowed by a network policy to be dropped. If not specified, the default is true for each traffic direction that has rules, and false otherwise. For example, if a policy only has Ingress or IngressDeny rules, then the default for ingress is true and egress is false. If multiple policies apply to an endpoint, that endpoint's default deny will be enabled if any policy requests it. This is useful for creating broad-based network policies that will not cause endpoints to enter default-deny mode.
Whether or not the endpoint should have a default-deny rule applied to egress traffic.

Namespace is the namespace in which the secret exists. Context of use determines the default value if left out (e.g., "default").
Value matches the exact value of the header. Can be specified either alone or together with "Secret"; will be used as the header value if the secret can not be found in the latter case.
Headers is a list of HTTP headers which must be present in the request. If omitted or empty, requests are allowed regardless of headers present.
Host is an extended POSIX regex matched against the host header of a request. Examples: - foo.bar.com will match the host fooXbar.com or foo-bar.com - foo\.bar\.com will only match the host foo.bar.com If omitted or empty, the value of the host header is ignored.
Method is an extended POSIX regex matched against the method of a request, e.g. "GET", "POST", "PUT", "PATCH", "DELETE", ... If omitted or empty, all methods are allowed.
Path is an extended POSIX regex matched against the path of a request. Currently it can contain characters disallowed from the conventional "path" part of a URL as defined by RFC 3986. If omitted or empty, all paths are all allowed.
ServerNames is a list of allowed TLS SNI values. If not empty, then TLS must be present and one of the provided SNIs must be indicated in the TLS handshake.
TerminatingTLS is the TLS context for the connection terminated by the L7 proxy. For egress policy this specifies the server-side TLS parameters to be applied on the connections originated from the local endpoint and terminated by the L7 proxy. For ingress policy this specifies the server-side TLS parameters to be applied on the connections originated from a remote source and terminated by the L7 proxy.
Certificate is the file name or k8s secret item name for the certificate chain. If omitted, 'tls.crt' is assumed, if it exists. If given, the item must exist.
PrivateKey is the file name or k8s secret item name for the private key matching the certificate chain. If omitted, 'tls.key' is assumed, if it exists. If given, the item must exist.
Secret is the secret that contains the certificates and private key for the TLS context. By default, Cilium will search in this secret for the following items: - 'ca.crt' - Which represents the trusted CA to verify remote source. - 'tls.crt' - Which represents the public key certificate. - 'tls.key' - Which represents the private key matching the public key certificate.
Name is the name of the secret.
Namespace is the namespace in which the secret exists. Context of use determines the default value if left out (e.g., "default").
TrustedCA is the file name or k8s secret item name for the trusted CA. If omitted, 'ca.crt' is assumed, if it exists. If given, the item must exist.
IngressDeny is a list of IngressDenyRule which are enforced at ingress. Any rule inserted here will be denied regardless of the allowed ingress rules in the 'ingress' field. If omitted or empty, this rule does not apply at ingress.
FromCIDR is a list of IP blocks which the endpoint subject to the rule is allowed to receive connections from. Only connections which do *not* originate from the cluster or from the local host are subject to CIDR rules. In order to allow in-cluster connectivity, use the FromEndpoints field. This will match on the source IP address of incoming connections. Adding a prefix into FromCIDR or into FromCIDRSet with no ExcludeCIDRs is equivalent. Overlaps are allowed between FromCIDR and FromCIDRSet. Example: Any endpoint with the label "app=my-legacy-pet" is allowed to receive connections from 10.3.9.1
FromCIDRSet is a list of IP blocks which the endpoint subject to the rule is allowed to receive connections from in addition to FromEndpoints, along with a list of subnets contained within their corresponding IP block from which traffic should not be allowed. This will match on the source IP address of incoming connections. Adding a prefix into FromCIDR or into FromCIDRSet with no ExcludeCIDRs is equivalent. Overlaps are allowed between FromCIDR and FromCIDRSet. Example: Any endpoint with the label "app=my-legacy-pet" is allowed to receive connections from 10.0.0.0/8 except from IPs in subnet 10.96.0.0/12.
CIDR is a CIDR prefix / IP Block.
CIDRGroupRef is a reference to a CiliumCIDRGroup object. A CiliumCIDRGroup contains a list of CIDRs that the endpoint, subject to the rule, can (Ingress/Egress) or cannot (IngressDeny/EgressDeny) receive connections from.
CIDRGroupSelector selects CiliumCIDRGroups by their labels, rather than by name.
matchExpressions is a list of label selector requirements. The requirements are ANDed.
key is the label key that the selector applies to.
operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.
values 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.
matchLabels 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.
ExceptCIDRs is a list of IP blocks which the endpoint subject to the rule is not allowed to initiate connections to. These CIDR prefixes should be contained within Cidr, using ExceptCIDRs together with CIDRGroupRef is not supported yet. These exceptions are only applied to the Cidr in this CIDRRule, and do not apply to any other CIDR prefixes in any other CIDRRules.
FromEndpoints is a list of endpoints identified by an EndpointSelector which are allowed to communicate with the endpoint subject to the rule. Example: Any endpoint with the label "role=backend" can be consumed by any endpoint carrying the label "role=frontend". Note that while an empty non-nil FromEndpoints does not select anything, nil FromEndpoints is implicitly treated as a wildcard selector if ToPorts are also specified. To select everything, use one EndpointSelector without any match requirements.
matchExpressions is a list of label selector requirements. The requirements are ANDed.
key is the label key that the selector applies to.
operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.
values 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.
matchLabels 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.
FromEntities is a list of special entities which the endpoint subject to the rule is allowed to receive connections from. Supported entities are `world`, `cluster`, `cluster-mesh`, `host`, `remote-node`, `kube-apiserver`, `ingress`, `init`, `health`, `unmanaged`, `none` and `all`.
FromGroups allows policies to reference CIDRs provided by external integrations. Currently, only AWS is supported, and the rule can select by multiple sub directives. FromGroups entries are functionally equivalent to FromCIDR, and have the same limitiations. They cannot select traffic originating from within the cluster. Example: fromGroups: - aws: securityGroupsIds: - 'sg-XXXXXXXXXXXXX'
AWSGroup is an structure that can be used to whitelisting information from AWS integration
Labels selects AWS ENIs by labels. Multiple labels are AND-ed together.
Deprecated: Region is unused.
SecurityGroupsIds selects VPC SecurityGroups by IDs. If multiple IDs are specified, they are OR-ed together. Note that this may be AND-ed with any Names specified. Specifying both IDs and Names is not recommended.
SecurityGroupsNames selects VPC SecurityGroups by name. If multiple names are specified, they are OR-ed together. Note that this may be AND-ed with any IDs specified. Specifying both IDs and Names is not recommended.
FromNodes is a list of nodes identified by an EndpointSelector which are allowed to communicate with the endpoint subject to the rule.
matchExpressions is a list of label selector requirements. The requirements are ANDed.
key is the label key that the selector applies to.
operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.
values 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.
matchLabels 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.
Deprecated.
ICMPs is a list of ICMP rule identified by type number which the endpoint subject to the rule is not allowed to receive connections on. Example: Any endpoint with the label "app=httpd" can not accept incoming type 8 ICMP connections.
Fields is a list of ICMP fields.
Family is a IP address version. Currently, we support `IPv4` and `IPv6`. `IPv4` is set as default.
Type is a ICMP-type. It should be an 8bit code (0-255), or it's CamelCase name (for example, "EchoReply"). Allowed ICMP types are: Ipv4: EchoReply | DestinationUnreachable | Redirect | Echo | EchoRequest | RouterAdvertisement | RouterSelection | TimeExceeded | ParameterProblem | Timestamp | TimestampReply | Photuris | ExtendedEcho Request | ExtendedEcho Reply Ipv6: DestinationUnreachable | PacketTooBig | TimeExceeded | ParameterProblem | EchoRequest | EchoReply | MulticastListenerQuery| MulticastListenerReport | MulticastListenerDone | RouterSolicitation | RouterAdvertisement | NeighborSolicitation | NeighborAdvertisement | RedirectMessage | RouterRenumbering | ICMPNodeInformationQuery | ICMPNodeInformationResponse | InverseNeighborDiscoverySolicitation | InverseNeighborDiscoveryAdvertisement | HomeAgentAddressDiscoveryRequest | HomeAgentAddressDiscoveryReply | MobilePrefixSolicitation | MobilePrefixAdvertisement | DuplicateAddressRequestCodeSuffix | DuplicateAddressConfirmationCodeSuffix | ExtendedEchoRequest | ExtendedEchoReply
ToPorts is a list of destination ports identified by port number and protocol which the endpoint subject to the rule is not allowed to receive connections on. Example: Any endpoint with the label "app=httpd" can not accept incoming connections on port 80/tcp.
Ports is a list of L4 port/protocol
EndPort can only be an L4 port number.
Port can be an L4 port number, or a name in the form of "http" or "http-8080".
Protocol is the L4 protocol. If "ANY", omitted or empty, any protocols with transport ports (TCP, UDP, SCTP) match. Accepted values: "TCP", "UDP", "SCTP", "VRRP", "IGMP", "GRE", "IPIP", "IPV6", "ESP", "AH", "ANY" Tunnel/encapsulation protocols (GRE, IPIP, IPV6, ESP, AH) and other extended IP protocols (VRRP, IGMP) require the --enable-extended-ip-protocols flag to be set. These protocols do not use transport-layer ports. Matching on ICMP is not supported. Named port specified for a container may narrow this down, but may not contradict this.
Labels is a list of optional strings which can be used to re-identify the rule or to store metadata. It is possible to lookup or delete strings based on labels. Labels are not required to be unique, multiple rules can have overlapping or identical labels.
Source can be one of the above values (e.g.: LabelSourceK8s).
Log specifies custom policy-specific Hubble logging configuration.
Value is a free-form string that is included in Hubble flows that match this policy. The string is limited to 32 printable characters.
NodeSelector selects all nodes which should be subject to this rule. EndpointSelector and NodeSelector cannot be both empty and are mutually exclusive. Can only be used in CiliumClusterwideNetworkPolicies.
matchExpressions is a list of label selector requirements. The requirements are ANDed.
key is the label key that the selector applies to.
operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.
values 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.
matchLabels 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.
Status is the status of the Cilium policy rule
The last time the condition transitioned from one status to another.
A human readable message indicating details about the transition.
The reason for the condition's last transition.
The status of the condition, one of True, False, or Unknown
The type of the policy condition
DerivativePolicies is the status of all policies derived from the Cilium policy
Annotations corresponds to the Annotations in the ObjectMeta of the CNP that have been realized on the node for CNP. That is, if a CNP has been imported and has been assigned annotation X=Y by the user, Annotations in CiliumNetworkPolicyNodeStatus will be X=Y once the CNP that was imported corresponding to Annotation X=Y has been realized on the node.
Enforcing is set to true once all endpoints present at the time the policy has been imported are enforcing this policy.
Error describes any error that occurred when parsing or importing the policy, or realizing the policy for the endpoints to which it applies on the node.
LastUpdated contains the last time this status was updated
Revision is the policy revision of the repository which first implemented this policy.
OK is true when the policy has been parsed and imported successfully into the in-memory policy repository on the node.
