Description

DaemonSet represents the configuration of a daemon set.

Type

object

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 meta/v1

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

.spec

object

DaemonSetSpec is the specification of a daemon set.

.status

object

DaemonSetStatus represents the current status of a daemon set.

.spec
Description

DaemonSetSpec is the specification of a daemon set.

Type

object

Required
  • selector

  • template

Property Type Description

minReadySeconds

integer

The minimum number of seconds for which a newly created DaemonSet pod should be ready without any of its container crashing, for it to be considered available. Defaults to 0 (pod will be considered available as soon as it is ready).

revisionHistoryLimit

integer

The number of old history to retain to allow rollback. This is a pointer to distinguish between explicit zero and not specified. Defaults to 10.

selector

LabelSelector meta/v1

A label query over pods that are managed by the daemon set. Must match in order to be controlled. It must match the pod template’s labels. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors

template

PodTemplateSpec core/v1

An object that describes the pod that will be created. The DaemonSet will create exactly one copy of this pod on every node that matches the template’s node selector (or on every node if no node selector is specified). More info: https://kubernetes.io/docs/concepts/workloads/controllers/replicationcontroller#pod-template

updateStrategy

object

DaemonSetUpdateStrategy is a struct used to control the update strategy for a DaemonSet.

.spec.updateStrategy
Description

DaemonSetUpdateStrategy is a struct used to control the update strategy for a DaemonSet.

Type

object

Property Type Description

rollingUpdate

object

Spec to control the desired behavior of daemon set rolling update.

type

string

Type of daemon set update. Can be "RollingUpdate" or "OnDelete". Default is RollingUpdate.

.spec.updateStrategy.rollingUpdate
Description

Spec to control the desired behavior of daemon set rolling update.

Type

object

Property Type Description

maxUnavailable

IntOrString util/intstr

The maximum number of DaemonSet pods that can be unavailable during the update. Value can be an absolute number (ex: 5) or a percentage of total number of DaemonSet pods at the start of the update (ex: 10%). Absolute number is calculated from percentage by rounding up. This cannot be 0. Default value is 1. Example: when this is set to 30%, at most 30% of the total number of nodes that should be running the daemon pod (i.e. status.desiredNumberScheduled) can have their pods stopped for an update at any given time. The update starts by stopping at most 30% of those DaemonSet pods and then brings up new DaemonSet pods in their place. Once the new pods are available, it then proceeds onto other DaemonSet pods, thus ensuring that at least 70% of original number of DaemonSet pods are available at all times during the update.

.status
Description

DaemonSetStatus represents the current status of a daemon set.

Type

object

Required
  • currentNumberScheduled

  • numberMisscheduled

  • desiredNumberScheduled

  • numberReady

Property Type Description

collisionCount

integer

Count of hash collisions for the DaemonSet. The DaemonSet controller uses this field as a collision avoidance mechanism when it needs to create the name for the newest ControllerRevision.

conditions

array

Represents the latest available observations of a DaemonSet’s current state.

conditions[]

object

DaemonSetCondition describes the state of a DaemonSet at a certain point.

currentNumberScheduled

integer

The number of nodes that are running at least 1 daemon pod and are supposed to run the daemon pod. More info: https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/

desiredNumberScheduled

integer

The total number of nodes that should be running the daemon pod (including nodes correctly running the daemon pod). More info: https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/

numberAvailable

integer

The number of nodes that should be running the daemon pod and have one or more of the daemon pod running and available (ready for at least spec.minReadySeconds)

numberMisscheduled

integer

The number of nodes that are running the daemon pod, but are not supposed to run the daemon pod. More info: https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/

numberReady

integer

The number of nodes that should be running the daemon pod and have one or more of the daemon pod running and ready.

numberUnavailable

integer

The number of nodes that should be running the daemon pod and have none of the daemon pod running and available (ready for at least spec.minReadySeconds)

observedGeneration

integer

The most recent generation observed by the daemon set controller.

updatedNumberScheduled

integer

The total number of nodes that are running updated daemon pod

.status.conditions
