Node [core/v1]

    Node is a worker node in Kubernetes. Each node will have a unique identifier in the cache (i.e. in etcd).

    Type

    .spec

    Description

    NodeSpec describes the attributes that a node is created with.

    Type

    object

    PropertyTypeDescription

    configSource

    NodeConfigSource core/v1

    If specified, the source to get node configuration from The DynamicKubeletConfig feature gate must be enabled for the Kubelet to use this field

    externalID

    string

    Deprecated. Not all kubelets will set this field. Remove field after 1.13. see:

    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 (Taint core/v1)

    If specified, the node’s taints.

    Type

    object

    PropertyTypeDescription

    addresses

    array (NodeAddress core/v1)

    List of addresses reachable to the node. Queried from cloud provider, if available. More info: 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.

    allocatable

    Allocatable represents the resources of a node that are available for scheduling. Defaults to Capacity.

    capacity

    object (Quantity api/resource)

    .status.config

    Description

    NodeConfigStatus describes the status of the config assigned by Node.Spec.ConfigSource.

    Type

    object

    PropertyTypeDescription

    active

    NodeConfigSource core/v1

    Active reports the checkpointed config the node is actively using. Active will represent either the current version of the Assigned config, or the current LastKnownGood config, depending on whether attempting to use the Assigned config results in an error.

    assigned

    Assigned reports the checkpointed config the node will try to use. When Node.Spec.ConfigSource is updated, the node checkpoints the associated config payload to local disk, along with a record indicating intended config. The node refers to this record to choose its config checkpoint, and reports this record in Assigned. Assigned only updates in the status after the record has been checkpointed to disk. When the Kubelet is restarted, it tries to make the Assigned config the Active config by loading and validating the checkpointed payload identified by Assigned.

    error

    string

    Error describes any problems reconciling the Spec.ConfigSource to the Active config. Errors may occur, for example, attempting to checkpoint Spec.ConfigSource to the local Assigned record, attempting to checkpoint the payload associated with Spec.ConfigSource, attempting to load or validate the Assigned config, etc. Errors may occur at different points while syncing config. Earlier errors (e.g. download or checkpointing errors) will not result in a rollback to LastKnownGood, and may resolve across Kubelet retries. Later errors (e.g. loading or validating a checkpointed config) will result in a rollback to LastKnownGood. In the latter case, it is usually possible to resolve the error by fixing the config assigned in Spec.ConfigSource. You can find additional information for debugging by searching the error message in the Kubelet log. Error is a human-readable description of the error state; machines can check whether or not Error is empty, but should not rely on the stability of the Error text across Kubelet versions.

    lastKnownGood

    NodeConfigSource core/v1

    LastKnownGood reports the checkpointed config the node will fall back to when it encounters an error attempting to use the Assigned config. The Assigned config becomes the LastKnownGood config when the node determines that the Assigned config is stable and correct. This is currently implemented as a 10-minute soak period starting when the local record of Assigned config is updated. If the Assigned config is Active at the end of this period, it becomes the LastKnownGood. Note that if Spec.ConfigSource is reset to nil (use local defaults), the LastKnownGood is also immediately reset to nil, because the local default config is always assumed good. You should not make assumptions about the node’s method of determining config stability and correctness, as this may change or become configurable in the future.

    Table 1. Global guery parameters
    ParameterTypeDescription

    pretty

    string

    If ‘true’, then the output is pretty printed.

    HTTP method

    DELETE

    Description

    delete collection of Node

    Table 2. Query parameters
    ParameterTypeDescription

    continue

    string

    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.

    dryRun

    string

    When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed

    fieldSelector

    string

    A selector to restrict the list of returned objects by their fields. Defaults to everything.

    gracePeriodSeconds

    integer

    The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.

    labelSelector

    string

    A selector to restrict the list of returned objects by their labels. Defaults to everything.

    limit

    integer

    limit is a maximum number of responses to return for a list call. If more items exist, the server will set the continue field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true.

    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.

    orphanDependents

    boolean

    Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the “orphan” finalizer will be added to/removed from the object’s finalizers list. Either this field or PropagationPolicy may be set, but not both.

    propagationPolicy

    string

    Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: ‘Orphan’ - orphan the dependents; ‘Background’ - allow the garbage collector to delete the dependents in the background; ‘Foreground’ - a cascading policy that deletes all dependents in the foreground.

    resourceVersion

    string

    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.

    resourceVersionMatch

    string

    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 for details.

    Defaults to unset

    timeoutSeconds

    integer

    Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.

    allowWatchBookmarks

    boolean

    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.

    continue

    string

    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.
