Endpoints [v1]
Description
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"}],
Ports: [{"name": "a", "port": 93}, {"name": "b", "port": 76}]
},
]

Specification
Property | Type | Description |
---|---|---|
|
| 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 |
| Standard object’s metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata | |
|
| The set of all endpoints is the union of all subsets. Addresses are placed into subsets according to the IPs they share. A single address with multiple ports, some of which are ready and some of which are not (because they come from different containers) will result in the address being displayed in different subsets for the different ports. No address will appear in both Addresses and NotReadyAddresses in the same subset. Sets of addresses and ports that comprise a service. |
|
| 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 ] |
.subsets
Description
The set of all endpoints is the union of all subsets. Addresses are placed into subsets according to the IPs they share. A single address with multiple ports, some of which are ready and some of which are not (because they come from different containers) will result in the address being displayed in different subsets for the different ports.

.subsets[]
Description
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 ]

| API version of the referent. |
|
| If referring to a piece of an object instead of an entire object, this string should contain a valid JSON/Go field access statement, such as desiredState.manifest.containers[2]. For example, if the object reference is to a container within a pod, this would take on a value like: “spec.containers{name}” (where “name” refers to the name of the container that triggered the event) or if no container name is specified “spec.containers[2]” (container with index 2 in this pod). This syntax is chosen only to have some well-defined way of referencing a part of an object. |

This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered. |
