service

Service is a named abstraction of software service (for example, mysql) consisting of local port (for example 3306) that the proxy listens on, and the selector that determines which pods will answer requests sent through the proxy.

    new(name="", selector="", ports="")


Mixins
  • metadata

    Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/api-conventions.md#metadata


    Functions
    • mixinInstance

      mixinInstance(metadata)


    • withAnnotations

      withAnnotations(annotations)

      Annotations is an unstructured key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata. They are not queryable and should be preserved when modifying objects. More info: http://kubernetes.io/docs/user-guide/annotations


    • withAnnotationsMixin

      withAnnotationsMixin(annotations)

      Annotations is an unstructured key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata. They are not queryable and should be preserved when modifying objects. More info: http://kubernetes.io/docs/user-guide/annotations


    • withClusterName

      withClusterName(clusterName)

      The name of the cluster which the object belongs to. This is used to distinguish resources with same name and namespace in different clusters. This field is not set anywhere right now and apiserver is going to ignore it if set in create or update request.


    • withFinalizers

      withFinalizers(finalizers)

      Must be empty before the object is deleted from the registry. Each entry is an identifier for the responsible component that will remove the entry from the list. If the deletionTimestamp of the object is non-nil, entries in this list can only be removed.


    • withFinalizersMixin

      withFinalizersMixin(finalizers)

      Must be empty before the object is deleted from the registry. Each entry is an identifier for the responsible component that will remove the entry from the list. If the deletionTimestamp of the object is non-nil, entries in this list can only be removed.


    • withGenerateName

      withGenerateName(generateName)

      GenerateName is an optional prefix, used by the server, to generate a unique name ONLY IF the Name field has not been provided. If this field is used, the name returned to the client will be different than the name passed. This value will also be combined with a unique suffix. The provided value has the same validation rules as the Name field, and may be truncated by the length of the suffix required to make the value unique on the server.

      If this field is specified and the generated name exists, the server will NOT return a 409 - instead, it will either return 201 Created or 500 with Reason ServerTimeout indicating a unique name could not be found in the time allotted, and the client should retry (optionally after the time indicated in the Retry-After header).

      Applied only if Name is not specified. More info: https://git.k8s.io/community/contributors/devel/api-conventions.md#idempotency


    • withLabels

      withLabels(labels)

      Map of string keys and values that can be used to organize and categorize (scope and select) objects. May match selectors of replication controllers and services. More info: http://kubernetes.io/docs/user-guide/labels


    • withLabelsMixin

      withLabelsMixin(labels)

      Map of string keys and values that can be used to organize and categorize (scope and select) objects. May match selectors of replication controllers and services. More info: http://kubernetes.io/docs/user-guide/labels


    • withName

      withName(name)

      Name must be unique within a namespace. Is required when creating resources, although some resources may allow a client to request the generation of an appropriate name automatically. Name is primarily intended for creation idempotence and configuration definition. Cannot be updated. More info: http://kubernetes.io/docs/user-guide/identifiers#names


    • withNamespace

      withNamespace(namespace)

      Namespace defines the space within each name must be unique. An empty namespace is equivalent to the “default” namespace, but “default” is the canonical representation. Not all objects are required to be scoped to a namespace - the value of this field for those objects will be empty.

      Must be a DNS_LABEL. Cannot be updated. More info: http://kubernetes.io/docs/user-guide/namespaces


    • withOwnerReferences

      withOwnerReferences(ownerReferences)

      List of objects depended by this object. If ALL objects in the list have been deleted, this object will be garbage collected. If this object is managed by a controller, then an entry in this list will point to this controller, with the controller field set to true. There cannot be more than one managing controller.

      withOwnerReferences takes an array of type ownerReferencesType. You can create an instance of ownerReferencesType with hidden.meta.v1.ownerReference.new().

      see hidden.meta.v1.ownerReference


    • withOwnerReferencesMixin

      withOwnerReferencesMixin(ownerReferences)

      List of objects depended by this object. If ALL objects in the list have been deleted, this object will be garbage collected. If this object is managed by a controller, then an entry in this list will point to this controller, with the controller field set to true. There cannot be more than one managing controller.

    Mixins
    • initializers

      An initializer is a controller which enforces some system invariant at object creation time. This field is a list of initializers that have not yet acted on this object. If nil or empty, this object has been completely initialized. Otherwise, the object is considered uninitialized and is hidden (in list/watch and get calls) from clients that haven't explicitly asked to observe uninitialized objects.

      When an object is created, the system will populate this list with the current set of initializers. Only privileged users may set or modify this list. Once it is empty, it may not be modified further by any user.


      Functions
      • mixinInstance

        mixinInstance(initializers)


      • withPending

        withPending(pending)

        Pending is a list of initializers that must execute in order before this object is visible. When the last pending initializer is removed, and no failing result is set, the initializers struct will be set to nil and the object is considered as initialized and visible to all clients.

        withPending takes an array of type pendingType. You can create an instance of pendingType with hidden.meta.v1.initializer.new().

        see hidden.meta.v1.initializer


      • withPendingMixin

        withPendingMixin(pending)

  • spec

    Spec defines the behavior of a service. https://git.k8s.io/community/contributors/devel/api-conventions.md#spec-and-status


    Functions
    • mixinInstance

      mixinInstance(spec)


    • withClusterIp

      withClusterIp(clusterIp)

      clusterIP is the IP address of the service and is usually assigned randomly by the master. If an address is specified manually and is not in use by others, it will be allocated to the service; otherwise, creation of the service will fail. This field can not be changed through updates. Valid values are “None”, empty string (“”), or a valid IP address. “None” can be specified for headless services when proxying is not required. Only applies to types ClusterIP, NodePort, and LoadBalancer. Ignored if type is ExternalName. More info: https://kubernetes.io/docs/concepts/services-networking/service/#virtual-ips-and-service-proxies


    • withExternalIps

      withExternalIps(externalIps)

      externalIPs is a list of IP addresses for which nodes in the cluster will also accept traffic for this service. These IPs are not managed by Kubernetes. The user is responsible for ensuring that traffic arrives at a node with this IP. A common example is external load-balancers that are not part of the Kubernetes system.


    • withExternalIpsMixin

      withExternalIpsMixin(externalIps)

      externalIPs is a list of IP addresses for which nodes in the cluster will also accept traffic for this service. These IPs are not managed by Kubernetes. The user is responsible for ensuring that traffic arrives at a node with this IP. A common example is external load-balancers that are not part of the Kubernetes system.


    • withExternalName

      withExternalName(externalName)

      externalName is the external reference that kubedns or equivalent will return as a CNAME record for this service. No proxying will be involved. Must be a valid DNS name and requires Type to be ExternalName.


    • withExternalTrafficPolicy

      withExternalTrafficPolicy(externalTrafficPolicy)

      externalTrafficPolicy denotes if this Service desires to route external traffic to node-local or cluster-wide endpoints. “Local” preserves the client source IP and avoids a second hop for LoadBalancer and Nodeport type services, but risks potentially imbalanced traffic spreading. “Cluster” obscures the client source IP and may cause a second hop to another node, but should have good overall load-spreading.


    • withHealthCheckNodePort

      withHealthCheckNodePort(healthCheckNodePort)

      healthCheckNodePort specifies the healthcheck nodePort for the service. If not specified, HealthCheckNodePort is created by the service api backend with the allocated nodePort. Will use user-specified nodePort value if specified by the client. Only effects when Type is set to LoadBalancer and ExternalTrafficPolicy is set to Local.


    • withLoadBalancerIp

      withLoadBalancerIp(loadBalancerIp)

      Only applies to Service Type: LoadBalancer LoadBalancer will get created with the IP specified in this field. This feature depends on whether the underlying cloud-provider supports specifying the loadBalancerIP when a load balancer is created. This field will be ignored if the cloud-provider does not support the feature.


    • withLoadBalancerSourceRanges

      withLoadBalancerSourceRanges(loadBalancerSourceRanges)

      If specified and supported by the platform, this will restrict traffic through the cloud-provider load-balancer will be restricted to the specified client IPs. This field will be ignored if the cloud-provider does not support the feature.” More info: https://kubernetes.io/docs/tasks/access-application-cluster/configure-cloud-provider-firewall/


    • withLoadBalancerSourceRangesMixin

      withLoadBalancerSourceRangesMixin(loadBalancerSourceRanges)

      If specified and supported by the platform, this will restrict traffic through the cloud-provider load-balancer will be restricted to the specified client IPs. This field will be ignored if the cloud-provider does not support the feature.” More info: https://kubernetes.io/docs/tasks/access-application-cluster/configure-cloud-provider-firewall/


    • withPorts

      withPorts(ports)

      The list of ports that are exposed by this service. More info: https://kubernetes.io/docs/concepts/services-networking/service/#virtual-ips-and-service-proxies

      withPorts takes an array of type portsType. You can create an instance of portsType with hidden.core.v1.servicePort.new().

      see hidden.core.v1.servicePort


    • withPortsMixin

      withPortsMixin(ports)

      The list of ports that are exposed by this service. More info: https://kubernetes.io/docs/concepts/services-networking/service/#virtual-ips-and-service-proxies

      withPortsMixin takes an array of type portsType. You can create an instance of portsType with hidden.core.v1.servicePort.new().

      see hidden.core.v1.servicePort


    • withPublishNotReadyAddresses

      withPublishNotReadyAddresses(publishNotReadyAddresses)

      publishNotReadyAddresses, when set to true, indicates that DNS implementations must publish the notReadyAddresses of subsets for the Endpoints associated with the Service. The default value is false. The primary use case for setting this field is to use a StatefulSet’s Headless Service to propagate SRV records for its Pods without respect to their readiness for purpose of peer discovery. This field will replace the service.alpha.kubernetes.io/tolerate-unready-endpoints when that annotation is deprecated and all clients have been converted to use this field.


    • withSelector

      withSelector(selector)

      Route service traffic to pods with label keys and values matching this selector. If empty or not present, the service is assumed to have an external process managing its endpoints, which Kubernetes will not modify. Only applies to types ClusterIP, NodePort, and LoadBalancer. Ignored if type is ExternalName. More info: https://kubernetes.io/docs/concepts/services-networking/service/


    • withSelectorMixin

      withSelectorMixin(selector)

      Route service traffic to pods with label keys and values matching this selector. If empty or not present, the service is assumed to have an external process managing its endpoints, which Kubernetes will not modify. Only applies to types ClusterIP, NodePort, and LoadBalancer. Ignored if type is ExternalName. More info: https://kubernetes.io/docs/concepts/services-networking/service/


    • withSessionAffinity

      withSessionAffinity(sessionAffinity)

      Supports “ClientIP” and “None”. Used to maintain session affinity. Enable client IP based session affinity. Must be ClientIP or None. Defaults to None. More info: https://kubernetes.io/docs/concepts/services-networking/service/#virtual-ips-and-service-proxies


    • withType

      withType(type)

      type determines how the Service is exposed. Defaults to ClusterIP. Valid options are ExternalName, ClusterIP, NodePort, and LoadBalancer. “ExternalName” maps to the specified externalName. “ClusterIP” allocates a cluster-internal IP address for load-balancing to endpoints. Endpoints are determined by the selector or if that is not specified, by manual construction of an Endpoints object. If clusterIP is “None”, no virtual IP is allocated and the endpoints are published as a set of endpoints rather than a stable IP. “NodePort” builds on ClusterIP and allocates a port on every node which routes to the clusterIP. “LoadBalancer” builds on NodePort and creates an external load-balancer (if supported in the current cloud) which routes to the clusterIP. More info: https://kubernetes.io/docs/concepts/services-networking/service/#publishing-services---service-types
