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

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

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

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). The only allowed template.spec.restartPolicy value is "Always". 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.

Possible enum values: - "OnDelete" Replace the old daemons only when it’s killed - "RollingUpdate" Replace the old daemons by new ones using rolling update i.e replace them on each node one after the other.

.spec.updateStrategy.rollingUpdate

Description

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

Type

object

Property Type Description

maxSurge

IntOrString

The maximum number of nodes with an existing available DaemonSet pod that can have an updated DaemonSet pod during during an update. Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%). This can not be 0 if MaxUnavailable is 0. Absolute number is calculated from percentage by rounding up to a minimum of 1. Default value is 0. 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 a new pod created before the old pod is marked as deleted. The update starts by launching new pods on 30% of nodes. Once an updated pod is available (Ready for at least minReadySeconds) the old DaemonSet pod on that node is marked deleted. If the old pod becomes unavailable for any reason (Ready transitions to false, is evicted, or is drained) an updated pod is immediatedly created on that node without considering surge limits. Allowing surge implies the possibility that the resources consumed by the daemonset on any given node can double if the readiness check fails, and so resource intensive daemonsets should take into account that they may cause evictions during disruption.

maxUnavailable

IntOrString

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 if MaxSurge is 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.

desiredNumberScheduled

integer
