EndpointSlice [discovery.k8s.io/v1beta1]
Description
EndpointSlice represents a subset of the endpoints that implement a service. For a given service there may be multiple EndpointSlice objects, selected by labels, which must be joined to produce the full set of endpoints.

Required
addressType
endpoints
Specification
Property | Type | Description |
---|---|---|
|
| addressType specifies the type of address carried by this EndpointSlice. All addresses in this slice must be the same type. This field is immutable after creation. The following address types are currently supported: IPv4: Represents an IPv4 Address. IPv6: Represents an IPv6 Address. * FQDN: Represents a Fully Qualified Domain Name. |
|
| 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 |
|
| endpoints is a list of unique endpoints in this slice. Each slice may include a maximum of 1000 endpoints. |
|
| Endpoint represents a single logical “backend” implementing a service. |
|
| 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 |
| Standard object’s metadata. | |
|
| ports specifies the list of network ports exposed by each endpoint in this slice. Each port must have a unique name. When ports is empty, it indicates that there are no defined ports. When a port is defined with a nil port value, it indicates “all ports”. Each slice may include a maximum of 100 ports. |
|
| EndpointPort represents a Port used by an EndpointSlice |

Required
addresses
Property | Type | Description |
---|---|---|
|
| addresses of this endpoint. The contents of this field are interpreted according to the corresponding EndpointSlice addressType field. Consumers must handle different types of addresses in the context of their own capabilities. This must contain at least one address but no more than 100. |
|
| EndpointConditions represents the current condition of an endpoint. |
|
| hostname of this endpoint. This field may be used by consumers of endpoints to distinguish endpoints from each other (e.g. in DNS names). Multiple endpoints which use the same hostname should be considered fungible (e.g. multiple A values in DNS). Must pass DNS Label (RFC 1123) validation. |
| targetRef is a reference to a Kubernetes object that represents this endpoint. | |
|
| topology contains arbitrary topology information associated with the endpoint. These key-value pairs must conform with the label format. https://kubernetes.io/docs/concepts/overview/working-with-objects/labels Topology may include a maximum of 16 key-value pairs. This includes, but is not limited to the following well known keys: kubernetes.io/hostname: the value indicates the hostname of the node where the endpoint is located. This should match the corresponding node label. topology.kubernetes.io/zone: the value indicates the zone where the endpoint is located. This should match the corresponding node label. * topology.kubernetes.io/region: the value indicates the region where the endpoint is located. This should match the corresponding node label. |
.endpoints[].conditions
Description
EndpointConditions represents the current condition of an endpoint.

Property | Type | Description |
---|---|---|
|
| ready indicates that this endpoint is prepared to receive traffic, according to whatever system is managing the endpoint. A nil value indicates an unknown state. In most cases consumers should interpret this unknown state as ready. |
.ports
Description
ports specifies the list of network ports exposed by each endpoint in this slice. Each port must have a unique name. When ports is empty, it indicates that there are no defined ports. When a port is defined with a nil port value, it indicates “all ports”. Each slice may include a maximum of 100 ports.
Type
array
.ports[]
Description
EndpointPort represents a Port used by an EndpointSlice
Type
object
Property | Type | Description |
---|---|---|
|
| The application protocol for this port. This field follows standard Kubernetes label syntax. Un-prefixed names are reserved for IANA standard service names (as per RFC-6335 and http://www.iana.org/assignments/service-names). Non-standard protocols should use prefixed names such as mycompany.com/my-custom-protocol. |
|
| The name of this port. All ports in an EndpointSlice must have a unique name. If the EndpointSlice is dervied from a Kubernetes service, this corresponds to the Service.ports[].name. Name must either be an empty string or pass DNS_LABEL validation: must be no more than 63 characters long. must consist of lower case alphanumeric characters or ‘-‘. * must start and end with an alphanumeric character. Default is empty string. |
|
| The port number of the endpoint. If this is not specified, ports are not restricted and must be interpreted in the context of the specific consumer. |
|
| The IP protocol for this port. Must be UDP, TCP, or SCTP. Default is TCP. |

/apis/discovery.k8s.io/v1beta1/endpointslices
Parameter | Type | Description |
---|---|---|
|
| allowWatchBookmarks requests watch events with type “BOOKMARK”. Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server’s discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored. If the feature gate WatchBookmarks is not enabled in apiserver, this field is ignored. |
|
| The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the “next key”. This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications. |
|
| A selector to restrict the list of returned objects by their fields. Defaults to everything. |
|
| A selector to restrict the list of returned objects by their labels. Defaults to everything. |
|
| limit is a maximum number of responses to return for a list call. If more items exist, the server will set the The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned. |
|
| If ‘true’, then the output is pretty printed. |
|
| resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset |
|
| resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset |
|
| Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity. |
|
| Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion. |
