type Container 

type Container struct {
	// Required: This must be a DNS_LABEL.  Each container in a pod must
	// have a unique name.
	Name string `json:"name" description:"name of the container; must be a DNS_LABEL and unique within the pod; cannot be updated"`
	// Optional.

	Ports []ContainerPort `json:"ports"`
}

Container represents a single container that is expected to be run on the host.

type ContainerPort 

type ContainerPort struct {
	Name          string `json:"name"`
	ContainerPort int32  `json:"containerPort"`
	Protocol      string `json:"protocol"`
}

type DaemonEndpoint 

type DaemonEndpoint struct {

	// Port number of the given endpoint.
	Port int32 `json:"Port"`
}

DaemonEndpoint contains information about a single Daemon endpoint.

type Discovery 

type Discovery struct {
	Conf *config.KubernetesSDConfig
	// contains filtered or unexported fields
}

Discovery implements a TargetProvider for Kubernetes services.

func (*Discovery) Initialize 

func (kd *Discovery) Initialize() error

Initialize sets up the discovery for usage.

func (*Discovery) Run 

func (kd *Discovery) Run(ctx context.Context, ch chan<- []*config.TargetGroup)

Run implements the TargetProvider interface.

type EndpointAddress 

type EndpointAddress struct {
	// The IP of this endpoint.
	// TODO: This should allow hostname or IP, see #4447.
	IP string `json:"ip" description:"IP address of the endpoint"`
}

EndpointAddress is a tuple that describes single IP address.

type EndpointPort 

type EndpointPort struct {
	// The port number.
	Port int `json:"port" description:"port number of the endpoint"`

	// The IP protocol for this port.
	Protocol Protocol `json:"protocol,omitempty" description:"protocol for this port; must be UDP or TCP; TCP if unspecified"`
}

type EndpointSubset 

type EndpointSubset struct {
	Addresses []EndpointAddress `json:"addresses,omitempty" description:"IP addresses which offer the related ports"`
	Ports     []EndpointPort    `json:"ports,omitempty" description:"port numbers available on the related IP addresses"`
}

EndpointSubset is a group of addresses with a common set of ports. The expanded set of endpoints is the Cartesian product of Addresses x Ports. For example, given: 

{
  Addresses: [{"ip": "10.10.1.1"}, {"ip": "10.10.2.2"}],
  Ports:     [{"name": "a", "port": 8675}, {"name": "b", "port": 309}]
}

The resulting set of endpoints can be viewed as: 

a: [ 10.10.1.1:8675, 10.10.2.2:8675 ],
b: [ 10.10.1.1:309, 10.10.2.2:309 ]

type Endpoints 

type Endpoints struct {
	ObjectMeta `` /* 136-byte string literal not displayed */

	// The set of all endpoints is the union of all subsets.
	Subsets []EndpointSubset `json:"subsets" description:"sets of addresses and ports that comprise a service"`
}

Endpoints is a collection of endpoints that implement the actual service. Example: 

 Name: "mysvc",
 Subsets: [
   {
     Addresses: [{"ip": "10.10.1.1"}, {"ip": "10.10.2.2"}],
     Ports: [{"name": "a", "port": 8675}, {"name": "b", "port": 309}]
   },
   {
     Addresses: [{"ip": "10.10.3.3"}],

	Deleted  EventType = "DELETED"
)

Possible values for EventType.

type ListMeta 

type ListMeta struct {
	// An opaque value that represents the version of this response for use with optimistic
	// concurrency and change monitoring endpoints.  Clients must treat these values as opaque
	// and values may only be valid for a particular resource or set of resources. Only servers
	// will generate resource versions.
	ResourceVersion string `` /* 388-byte string literal not displayed */
}

ListMeta describes metadata that synthetic resources must have, including lists and various status objects.

type Node 

type Node struct {
	ObjectMeta `` /* 136-byte string literal not displayed */

	// Status describes the current status of a Node
	Status NodeStatus `` /* 190-byte string literal not displayed */

type NodeAddress 

type NodeAddress struct {
	Type    NodeAddressType `json:"type" description:"node address type, one of Hostname, ExternalIP or InternalIP"`
	Address string          `json:"address" description:"the node address"`
}

NodeAddress defines the address of a node.

type NodeAddressType 

type NodeAddressType string

NodeAddressType can legally only have the values defined as constants below. 

const (
	NodeLegacyHostIP NodeAddressType = "LegacyHostIP"
	NodeHostName     NodeAddressType = "Hostname"
	NodeExternalIP   NodeAddressType = "ExternalIP"
	NodeInternalIP   NodeAddressType = "InternalIP"
)

These are valid address types of node. NodeLegacyHostIP is used to transit from out-dated HostIP field to NodeAddress.

type NodeDaemonEndpoints 

type NodeDaemonEndpoints struct {

	DaemonEndpoints NodeDaemonEndpoints `json:"daemonEndpoints,omitempty"`
}

NodeStatus is information about the current status of a node.

type ObjectMeta 

type ObjectMeta struct {
	// Name is unique within a namespace.  Name 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.
	Name string `` /* 192-byte string literal not displayed */

	// Namespace defines the space within which 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.
	Namespace string `` /* 167-byte string literal not displayed */

	ResourceVersion string `` /* 388-byte string literal not displayed */

	// TODO: replace map[string]string with labels.LabelSet type
	Labels map[string]string `` /* 239-byte string literal not displayed */

	// external tooling. They are not queryable and should be preserved when modifying
	// objects.

	// ProtocolUDP is the UDP protocol.
	ProtocolUDP Protocol = "UDP"
)
