preemption, resource contention, etc. The handler is not called if the
container crashes or exits. The Pod's termination grace period countdown begins before the
PreStop hook is executed. Regardless of the outcome of the handler, the
container will eventually terminate within the Pod's termination grace
period (unless delayed by finalizers). Other management of the container blocks until the hook completes

restartPolicy
string
RestartPolicy defines the restart behavior of individual containers in a pod.
This field may only be set for init containers, and the only allowed value is "Always".
For non-init containers or when this field is not specified,
the restart behavior is defined by the Pod's restart policy and the container type.
Setting the RestartPolicy as "Always" for the init container will have the following effect:
this init container will be continually restarted on
exit until all regular containers have terminated. Once all regular
containers have completed, all init containers with restartPolicy "Always"
will be shut down. This lifecycle differs from normal init containers and
is often referred to as a "sidecar" container. Although this init
container still starts in the init container sequence, it does not wait
for the container to complete before proceeding to the next init
container. Instead, the next init container starts immediately after this
init container is started, or after any startupProbe has successfully
completed.

The grace period is the duration in seconds after the processes running in the pod are sent
a termination signal and the time when the processes are forcibly halted with a kill signal.
Set this value longer than the expected cleanup time for your process.
If this value is nil, the pod's terminationGracePeriodSeconds will be used. Otherwise, this
value overrides the value provided by the pod spec.
Value must be non-negative integer. The value zero indicates stop immediately via
the kill signal (no opportunity to shut down).
This is a beta field and requires enabling ProbeTerminationGracePeriod feature gate.

sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the
first client attaches to stdin, and then remains open and accepts data until the client disconnects,
at which time stdin is closed and remains closed until the container is restarted. If this
flag is false, a container processes that reads from stdin will never receive an EOF.

recursively.
If ReadOnly is false, this field has no meaning and must be unspecified.
If ReadOnly is true, and this field is set to Disabled, the mount is not made
recursively read-only. If this field is set to IfPossible, the mount is made
recursively read-only, if it is supported by the container runtime. If this
field is set to Enabled, the mount is made recursively read-only if it is
supported by the container runtime, otherwise the pod will not be started and
an error will be generated to indicate the reason.
If this field is set to IfPossible or Enabled, MountPropagation must be set to
None (or be unspecified, which defaults to None).
If this field is not specified, it is treated as an equivalent of Disabled.

dataSource field can be used to specify either:
* An existing VolumeSnapshot object (snapshot.storage.k8s.io/VolumeSnapshot)
* An existing PVC (PersistentVolumeClaim)
If the provisioner or an external controller can support the specified data source,
it will create a new volume based on the contents of the specified data source.
When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef,
and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified.
If the namespace is specified, then dataSourceRef will not be copied to dataSource.

dataSourceRef object
dataSourceRef specifies the object from which to populate the volume with data, if a non-empty
volume is desired. This may be any object from a non-empty API group (non
core object) or a PersistentVolumeClaim object.
When this field is specified, volume binding will only succeed if the type of
the specified object matches some installed volume populator or dynamic
provisioner.
This field will replace the functionality of the dataSource field and as such
if both fields are non-empty, they must have the same value. For backwards
compatibility, when namespace isn't specified in dataSourceRef,
both fields (dataSource and dataSourceRef) will be set to the same
value automatically if one of them is empty and the other is non-empty.
When namespace is specified in dataSourceRef,
dataSource isn't set to the same value and must be empty.
There are three important differences between dataSource and dataSourceRef:
* While dataSource only allows two specific types of objects, dataSourceRef
allows any non-core object, as well as PersistentVolumeClaim objects.
* While dataSource ignores disallowed values (dropping them), dataSourceRef
preserves all values, and generates an error if a disallowed value is
specified.
* While dataSource only allows local objects, dataSourceRef allows objects
in any namespaces.
(Beta) Using this field requires the AnyVolumeDataSource feature gate to be enabled.
(Alpha) Using the namespace field of dataSourceRef requires the CrossNamespaceVolumeDataSource feature gate to be enabled.

More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#class-1
volumeAttributesClassName
string
volumeAttributesClassName may be used to set the VolumeAttributesClass used by this claim.
If specified, the CSI driver will create or update the volume with the attributes defined
in the corresponding VolumeAttributesClass. This has a different purpose than storageClassName,
it can be changed after the claim is created. An empty string value means that no VolumeAttributesClass
will be applied to the claim but it's not allowed to reset this field to empty string once it is set.
If unspecified and the PersistentVolumeClaim is unbound, the default VolumeAttributesClass
will be set by the persistentvolume controller if it exists.
If the resource referred to by volumeAttributesClass does not exist, this PersistentVolumeClaim will be
set to a Pending state, as reflected by the modifyVolumeStatus field, until such as a resource
exists.
More info: https://kubernetes.io/docs/concepts/storage/volume-attributes-classes/

If the key is empty, operator must be Exists; this combination means to match all values and all keys.
operator
string
Operator represents a key's relationship to the value.
Valid operators are Exists and Equal. Defaults to Equal.
Exists is equivalent to wildcard for value, so that a pod can
tolerate all taints of a particular category.
tolerationSeconds
integer
TolerationSeconds represents the period of time the toleration (which must be
of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default,
it is not set, which means tolerate the taint forever (do not evict). Zero and
negative values will be treated as 0 (evict immediately) by the system.
format:
int64

spreading will be calculated. The keys are used to lookup values from the
incoming pod labels, those key-value labels are ANDed with labelSelector
to select the group of existing pods over which spreading will be calculated
for the incoming pod. The same key is forbidden to exist in both MatchLabelKeys and LabelSelector.
MatchLabelKeys cannot be set when LabelSelector isn't set.
Keys that don't exist in the incoming pod labels will
be ignored. A null or empty list means only match against labelSelector.
This is a beta field and requires the MatchLabelKeysInPodTopologySpread feature gate to be enabled (enabled by default).
maxSkew
integer required
MaxSkew describes the degree to which pods may be unevenly distributed.
When `whenUnsatisfiable=DoNotSchedule`, it is the maximum permitted difference
between the number of matching pods in the target topology and the global minimum.
The global minimum is the minimum number of matching 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 satisfy it.
It's a required field. Default value is 1 and 0 is not allowed.

int32
minDomains
integer
MinDomains indicates a minimum number of eligible domains.
When the number of eligible domains with matching topology keys is less than minDomains,
Pod Topology Spread 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.
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.

nodeAffinityPolicy
string
NodeAffinityPolicy indicates how we will treat Pod's nodeAffinity/nodeSelector
when calculating pod topology spread skew. Options are:
- Honor: only nodes matching nodeAffinity/nodeSelector are included in the calculations.
- Ignore: nodeAffinity/nodeSelector are ignored. All nodes are included in the calculations.
If this value is nil, the behavior is equivalent to the Honor policy.
This is a beta-level feature default enabled by the NodeInclusionPolicyInPodTopologySpread feature flag.
nodeTaintsPolicy
string
NodeTaintsPolicy indicates how we will treat node taints when calculating
pod topology spread skew. Options are:
- Honor: nodes without taints, along with tainted nodes for which the incoming pod
has a toleration, are included.
- Ignore: node taints are ignored. All nodes are included.
If this value is nil, the behavior is equivalent to the Ignore policy.
This is a beta-level feature default enabled by the NodeInclusionPolicyInPodTopologySpread feature flag.
topologyKey
string required
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 meet the requirements of
nodeAffinityPolicy and nodeTaintsPolicy.
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.
whenUnsatisfiable
string required
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 scheduler
won't make it *more* imbalanced.
It's a required field.
status object
DragonflyStatus defines the observed state of Dragonfly
isRollingUpdate
boolean
IsRollingUpdate is true if the Dragonfly instance is being updated
phase
string
Status of the Dragonfly Instance
It can be one of the following:
- "ready": The Dragonfly instance is ready to serve requests
- "configuring-replication": The controller is updating the master of the Dragonfly instance
- "resources-created": The Dragonfly instance resources were created but not yet configured
