DataSourceRef allows any non-core object, as well as PersistentVolumeClaim

them), DataSourceRef preserves all values, and generates
an error if a disallowed value is specified. (Beta) Using

pods in an eligible domain or zero if the number of eligible
domains is less than MinDomains. For example, in a 3-zone
cluster, MaxSkew is set to 1, and pods with the same labelSelector
spread as 2/2/1: In this case, the global minimum is 1.
| zone1 | zone2 | zone3 | | P P | P P | P | -
if MaxSkew is 1, incoming pod can only be scheduled to
zone3 to become 2/2/2; scheduling it onto zone1(zone2)
would make the ActualSkew(3-1) on zone1(zone2) violate
MaxSkew(1). - if MaxSkew is 2, incoming pod can be scheduled
onto any zone. When `whenUnsatisfiable=ScheduleAnyway`,
it is used to give higher precedence to topologies that

minDomains:
description: "MinDomains indicates a minimum number of eligible

treats \"global minimum\" as 0, and then the calculation
of Skew is performed. And when the number of eligible
domains with matching topology keys equals or greater
than minDomains, this value has no effect on scheduling.
As a result, when the number of eligible domains is less
than minDomains, scheduler won't schedule more than maxSkew
Pods to those domains. If value is nil, the constraint
behaves as if MinDomains is equal to 1. Valid values are
integers greater than 0. When value is not nil, WhenUnsatisfiable
must be DoNotSchedule. \n For example, in a 3-zone cluster,
MaxSkew is set to 2, MinDomains is set to 5 and pods with
the same labelSelector spread as 2/2/2: | zone1 | zone2
| zone3 | | P P | P P | P P | The number of domains
is less than 5(MinDomains), so \"global minimum\" is treated
as 0. In this situation, new pod with the same labelSelector
cannot be scheduled, because computed skew will be 3(3
- 0) if new Pod is scheduled to any of the three zones,
it will violate MaxSkew. \n This is an alpha field and
requires enabling MinDomainsInPodTopologySpread feature
gate."

topologyKey:
description: TopologyKey is the key of node labels. Nodes
that have a label with this key and identical values are
considered to be in the same topology. We consider each
<key, value> as a "bucket", and try to put balanced number
of pods into each bucket. We define a domain as a particular
instance of a topology. Also, we define an eligible domain
as a domain whose nodes match the node selector. e.g.
If TopologyKey is "kubernetes.io/hostname", each Node
is a domain of that topology. And, if TopologyKey is "topology.kubernetes.io/zone",
each zone is a domain of that topology. It's a required
field.
type: string
whenUnsatisfiable:
description: 'WhenUnsatisfiable indicates how to deal with
a pod if it doesn''t satisfy the spread constraint. -
DoNotSchedule (default) tells the scheduler not to schedule
it. - ScheduleAnyway tells the scheduler to schedule the
pod in any location, but giving higher precedence to topologies
that would help reduce the skew. A constraint is considered
"Unsatisfiable" for an incoming pod if and only if every
possible node assignment for that pod would violate "MaxSkew"
on some topology. For example, in a 3-zone cluster, MaxSkew
is set to 1, and pods with the same labelSelector spread
as 3/1/1: | zone1 | zone2 | zone3 | | P P P | P | P |
If WhenUnsatisfiable is set to DoNotSchedule, incoming
pod can only be scheduled to zone2(zone3) to become 3/2/1(3/1/2)
as ActualSkew(2-1) on zone2(zone3) satisfies MaxSkew(1).
In other words, the cluster can still be imbalanced, but

volume provisioning through a PersistentVolumeClaim (see EphemeralVolumeSource
for more information on the connection between this volume
type and PersistentVolumeClaim). \n Use PersistentVolumeClaim
or one of the vendor-specific APIs for volumes that persist
for longer than the lifecycle of an individual pod. \n Use

An existing PVC with that name that is not owned by the

the unrelated PVC is removed. If such a pre-created PVC
