Specification

Property Type Description

apiVersion

string

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

string

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

metadata

ObjectMeta

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

spec

object

NodeSpec describes the attributes that a node is created with.

status

object

NodeStatus is information about the current status of a node.

.spec

Description

NodeSpec describes the attributes that a node is created with.

Type

object

Property Type Description

configSource

object

NodeConfigSource specifies a source of node configuration. Exactly one subfield (excluding metadata) must be non-nil. This API is deprecated since 1.22

externalID

string

Deprecated. Not all kubelets will set this field. Remove field after 1.13. see: https://issues.k8s.io/61966

podCIDR

string

PodCIDR represents the pod IP range assigned to the node.

podCIDRs

array (string)

podCIDRs represents the IP ranges assigned to the node for usage by Pods on that node. If this field is specified, the 0th entry must match the podCIDR field. It may contain at most 1 value for each of IPv4 and IPv6.

providerID

string

ID of the node assigned by the cloud provider in the format: <ProviderName>://<ProviderSpecificNodeID>

taints

array

If specified, the node’s taints.

taints[]

object

The node this Taint is attached to has the "effect" on any pod that does not tolerate the Taint.

unschedulable

boolean

Unschedulable controls node schedulability of new pods. By default, node is schedulable. More info: https://kubernetes.io/docs/concepts/nodes/node/#manual-node-administration

.spec.configSource

Description

NodeConfigSource specifies a source of node configuration. Exactly one subfield (excluding metadata) must be non-nil. This API is deprecated since 1.22

Type

object

Property Type Description

configMap

object

ConfigMapNodeConfigSource contains the information to reference a ConfigMap as a config source for the Node. This API is deprecated since 1.22: https://git.k8s.io/enhancements/keps/sig-node/281-dynamic-kubelet-configuration

.spec.configSource.configMap

Description

ConfigMapNodeConfigSource contains the information to reference a ConfigMap as a config source for the Node. This API is deprecated since 1.22: https://git.k8s.io/enhancements/keps/sig-node/281-dynamic-kubelet-configuration

Type

object

Required

  • namespace

  • name

  • kubeletConfigKey

Property Type Description

kubeletConfigKey

string

KubeletConfigKey declares which key of the referenced ConfigMap corresponds to the KubeletConfiguration structure This field is required in all cases.

name

string

Name is the metadata.name of the referenced ConfigMap. This field is required in all cases.

namespace

string

Namespace is the metadata.namespace of the referenced ConfigMap. This field is required in all cases.

resourceVersion

string

ResourceVersion is the metadata.ResourceVersion of the referenced ConfigMap. This field is forbidden in Node.Spec, and required in Node.Status.

uid

string

UID is the metadata.UID of the referenced ConfigMap. This field is forbidden in Node.Spec, and required in Node.Status.

.spec.taints

Description

If specified, the node’s taints.

Type

array

.spec.taints[]

Description

The node this Taint is attached to has the "effect" on any pod that does not tolerate the Taint.

Type

object

Required

  • key

  • effect

Property Type Description

effect

string

Required. The effect of the taint on pods that do not tolerate the taint. Valid effects are NoSchedule, PreferNoSchedule and NoExecute.

Possible enum values: - "NoExecute" Evict any already-running pods that do not tolerate the taint. Currently enforced by NodeController. - "NoSchedule" Do not allow new pods to schedule onto the node unless they tolerate the taint, but allow all pods submitted to Kubelet without going through the scheduler to start, and allow all already-running pods to continue running. Enforced by the scheduler. - "PreferNoSchedule" Like TaintEffectNoSchedule, but the scheduler tries not to schedule new pods onto the node, rather than prohibiting new pods from scheduling onto the node entirely. Enforced by the scheduler.

key

string

Required. The taint key to be applied to a node.

timeAdded

Time

TimeAdded represents the time at which the taint was added. It is only written for NoExecute taints.

value

string

The taint value corresponding to the taint key.

.status

Description

NodeStatus is information about the current status of a node.

Type

object

Property Type Description

addresses

array

List of addresses reachable to the node. Queried from cloud provider, if available. More info: https://kubernetes.io/docs/concepts/nodes/node/#addresses Note: This field is declared as mergeable, but the merge key is not sufficiently unique, which can cause data corruption when it is merged. Callers should instead use a full-replacement patch. See http://pr.k8s.io/79391 for an example.

NodeAddress contains information for the node’s address.

allocatable

object (Quantity)
