HTTPIngressPath

class lightkube.models.networking_v1.HTTPIngressPath(backend, path=None, pathType=None)

HTTPIngressPath associates a path with a backend. Incoming urls matching the path are forwarded to the backend.

parameters

  • backend IngressBackend - Backend defines the referenced service endpoint to which the traffic will be forwarded to.
  • path str - (optional) Path is matched against the path of an incoming request. Currently it can contain characters disallowed from the conventional "path" part of a URL as defined by RFC 3986. Paths must begin with a '/'. When unspecified, all paths from incoming requests are matched.
  • pathType str - (optional) PathType determines the interpretation of the Path matching. PathType can be one of the following values: * Exact: Matches the URL path exactly. * Prefix: Matches based on a URL path prefix split by '/'. Matching is done on a path element by element basis. A path element refers is the list of labels in the path split by the '/' separator. A request is a match for path p if every p is an element-wise prefix of p of the request path. Note that if the last element of the path is a substring of the last element in request path, it is not a match (e.g. /foo/bar matches /foo/bar/baz, but does not match /foo/barbaz).
  • ImplementationSpecific: Interpretation of the Path matching is up to the IngressClass. Implementations can treat this as a separate PathType or treat it identically to Prefix or Exact path types. Implementations are required to support all path types.

HTTPIngressRuleValue

class lightkube.models.networking_v1.HTTPIngressRuleValue(paths)

HTTPIngressRuleValue is a list of http selectors pointing to backends. In the example: http:///? -> backend where where parts of the url correspond to RFC 3986, this resource will be used to match against everything after the last '/' and before the first '?' or '#'.

parameters

  • paths HTTPIngressPath - A collection of paths that map requests to backends.

IngressClassSpec provides information about the class of an Ingress.

parameters

  • controller str - (optional) Controller refers to the name of the controller that should handle this class. This allows for different "flavors" that are controlled by the same controller. For example, you may have different Parameters for the same implementing controller. This should be specified as a domain-prefixed path no more than 250 characters in length, e.g. "acme.io/ingress-controller". This field is immutable.
  • parameters core_v1.TypedLocalObjectReference - (optional) Parameters is a link to a custom resource containing additional configuration for the controller. This is optional if the controller does not require extra parameters.

IngressList

class lightkube.models.networking_v1.IngressList(items, apiVersion=None, kind=None, metadata=None)

IngressList is a collection of Ingress.

parameters

  • items Ingress - Items is the list of Ingress.

IngressRule

class lightkube.models.networking_v1.IngressRule(host=None, http=None)

IngressRule represents the rules mapping the paths under a specified host to the related backend services. Incoming requests are first evaluated for a host match, then routed to the backend associated with the matching IngressRuleValue.

parameters

  • host str - (optional) Host is the fully qualified domain name of a network host, as defined by RFC
  • Note the following deviations from the "host" part of the URI as defined in RFC 3986: 1. IPs are not allowed. Currently an IngressRuleValue can only apply to the IP in the Spec of the parent Ingress.
  • The : delimiter is not respected because ports are not allowed. Currently the port of an Ingress is implicitly :80 for http and :443 for https. Both these may change in the future. Incoming requests are matched against the host before the IngressRuleValue. If the host is unspecified, the Ingress routes all traffic based on the specified IngressRuleValue. Host can be "precise" which is a domain name without the terminating dot of a network host (e.g. "foo.bar.com") or "wildcard", which is a domain name prefixed with a single wildcard label (e.g. ".foo.com"). The wildcard character '' must appear by itself as the first DNS label and matches only a single label. You cannot have a wildcard label by itself (e.g. Host == "*"). Requests will be matched against the Host field in the following way: 1. If Host is precise, the request matches this rule if the http host header is equal to Host. 2. If Host is a wildcard, then the request matches this rule if the http host header is to equal to the suffix (removing the first label) of the wildcard rule.
  • http HTTPIngressRuleValue - (optional)

IngressServiceBackend

class lightkube.models.networking_v1.IngressServiceBackend(name, port=None)

IngressServiceBackend references a Kubernetes Service as a Backend.

parameters

  • name str - Name is the referenced service. The service must exist in the same namespace as the Ingress object.
  • port ServiceBackendPort - (optional) Port of the referenced service. A port name or port number is required for a IngressServiceBackend.

IngressSpec

class lightkube.models.networking_v1.IngressSpec(defaultBackend=None, ingressClassName=None, rules=None, tls=None)

IngressSpec describes the Ingress the user wishes to exist.

parameters

  • defaultBackend IngressBackend - (optional) DefaultBackend is the backend that should handle requests that don't match any rule. If Rules are not specified, DefaultBackend must be specified. If DefaultBackend is not set, the handling of requests that do not match any of the rules will be up to the Ingress controller.
  • ingressClassName str - (optional) IngressClassName is the name of the IngressClass cluster resource. The associated IngressClass defines which controller will implement the resource. This replaces the deprecated kubernetes.io/ingress.class annotation. For backwards compatibility, when that annotation is set, it must be given precedence over this field. The controller may emit a warning if the field and annotation have different values. Implementations of this API should ignore Ingresses without a class specified. An IngressClass resource may be marked as default, which can be used to set a default value for this field. For more information, refer to the IngressClass documentation.
  • rules IngressRule - (optional) A list of host rules used to configure the Ingress. If unspecified, or no rule matches, all traffic is sent to the default backend.
  • tls IngressTLS - (optional) TLS configuration. Currently the Ingress only supports a single TLS port, 443. If multiple members of this list specify different hosts, they will be multiplexed on the same port according to the hostname specified through the SNI TLS extension, if the ingress controller fulfilling the ingress supports SNI.

IngressStatus

class lightkube.models.networking_v1.IngressStatus(loadBalancer=None)

parameters

  • hosts List[str] - (optional) Hosts are a list of hosts included in the TLS certificate. The values in this list must match the name/s used in the tlsSecret. Defaults to the wildcard host setting for the loadbalancer controller fulfilling this Ingress, if left unspecified.
  • secretName str - (optional) SecretName is the name of the secret used to terminate TLS traffic on port
  • Field is left optional to allow TLS routing based on SNI hostname alone. If the SNI host in a listener conflicts with the "Host" header field used by an IngressRule, the SNI host is used for termination and value of the Host header is used for routing.

NetworkPolicyPeer

class lightkube.models.networking_v1.NetworkPolicyPeer(ipBlock=None, namespaceSelector=None, podSelector=None)

NetworkPolicyPeer describes a peer to allow traffic to/from. Only certain combinations of fields are allowed

parameters

  • ipBlock IPBlock - (optional) IPBlock defines policy on a particular IPBlock. If this field is set then neither of the other fields can be.
  • namespaceSelector meta_v1.LabelSelector - (optional) 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.
  • podSelector meta_v1.LabelSelector - (optional) This 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.

NetworkPolicyPort

class lightkube.models.networking_v1.NetworkPolicyPort(port=None, protocol=None)

NetworkPolicyPort describes a port to allow traffic on

parameters

  • port util_intstr.IntOrString - (optional) 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.

NetworkPolicySpec

class lightkube.models.networking_v1.NetworkPolicySpec(podSelector, egress=None, ingress=None, policyTypes=None)

NetworkPolicySpec provides the specification of a NetworkPolicy

parameters

  • podSelector meta_v1.LabelSelector - Selects the pods to which this NetworkPolicy object applies. The array of ingress rules is applied to any pods selected by this field. Multiple network policies can select the same set of pods. In this case, the ingress rules for each are combined additively. This field is NOT optional and follows standard label selector semantics. An empty podSelector matches all pods in this namespace.
  • egress NetworkPolicyEgressRule - (optional) List of egress rules to be applied to the selected pods. Outgoing traffic is allowed if there are no NetworkPolicies selecting the pod (and cluster policy otherwise allows the traffic), OR if the traffic matches at least one egress rule across all of the NetworkPolicy objects whose podSelector matches the pod. If this field is empty then this NetworkPolicy limits all outgoing traffic (and serves solely to ensure that the pods it selects are isolated by default). This field is beta-level in 1.8
  • ingress NetworkPolicyIngressRule - (optional) List of ingress rules to be applied to the selected pods. Traffic is allowed to a pod if there are no NetworkPolicies selecting the pod (and cluster policy otherwise allows the traffic), OR if the traffic source is the pod's local node, OR if the traffic matches at least one ingress rule across all of the NetworkPolicy objects whose podSelector matches the pod. If this field is empty then this NetworkPolicy does not allow any traffic (and serves solely to ensure that the pods it selects are isolated by default)
  • policyTypes List[str] - (optional) List of rule types that the NetworkPolicy relates to. Valid options are "Ingress", "Egress", or "Ingress,Egress". If this field is not specified, it will default based on the existence of Ingress or Egress rules; policies that contain an Egress section are assumed to affect Egress, and all policies (whether or not they contain an Ingress section) are assumed to affect Ingress. If you want to write an egress-only policy, you must explicitly specify policyTypes [ "Egress" ]. Likewise, if you want to write a policy that specifies that no egress is allowed, you must specify a policyTypes value that include "Egress" (since such a policy would not include an Egress section and would otherwise default to just [ "Ingress" ]). This field is beta-level in 1.8
