- **apiVersion**: apps/v1 - **kind**: ReplicaSet - **metadata** (}}">ObjectMeta) If the Labels of a ReplicaSet are empty, they are defaulted to be the same as the Pod(s) that the ReplicaSet manages. Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata - **spec** (}}">ReplicaSetSpec) Spec defines the specification of the desired behavior of the ReplicaSet. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status - **status** (}}">ReplicaSetStatus) Status is the most recently observed status of the ReplicaSet. This data may be out of date by some window of time. Populated by the system. Read-only. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status ## ReplicaSetSpec {#ReplicaSetSpec} ReplicaSetSpec is the specification of a ReplicaSet.

- **selector** (}}">LabelSelector), required Selector is a label query over pods that should match the replica count. Label keys and values that must match in order to be controlled by this replica set. It must match the pod template's labels. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors - **template** (}}">PodTemplateSpec) Template is the object that describes the pod that will be created if insufficient replicas are detected. More info: https://kubernetes.io/docs/concepts/workloads/controllers/replicationcontroller#pod-template - **replicas** (int32) Replicas is the number of desired replicas. This is a pointer to distinguish between explicit zero and unspecified. Defaults to 1. More info: https://kubernetes.io/docs/concepts/workloads/controllers/replicationcontroller/#what-is-a-replicationcontroller - **minReadySeconds** (int32) Minimum number of seconds for which a newly created 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) ## ReplicaSetStatus {#ReplicaSetStatus} ReplicaSetStatus represents the current status of a ReplicaSet.

- **replicas** (int32), required Replicas is the most recently oberved number of replicas. More info: https://kubernetes.io/docs/concepts/workloads/controllers/replicationcontroller/#what-is-a-replicationcontroller - **availableReplicas** (int32) The number of available replicas (ready for at least minReadySeconds) for this replica set. - **readyReplicas** (int32) readyReplicas is the number of pods targeted by this ReplicaSet with a Ready Condition. - **fullyLabeledReplicas** (int32) The number of pods that have labels matching the labels of the pod template of the replicaset. - **conditions** ([]ReplicaSetCondition) *Patch strategy: merge on key `type`* Represents the latest available observations of a replica set's current state. *ReplicaSetCondition describes the state of a replica set at a certain point.* - **conditions.status** (string), required Status of the condition, one of True, False, Unknown. - **conditions.type** (string), required Type of replica set condition. - **conditions.lastTransitionTime** (Time) The last time the condition transitioned from one status to another. *Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.* - **conditions.message** (string) A human readable message indicating details about the transition. - **conditions.reason** (string) The reason for the condition's last transition. - **observedGeneration** (int64) ObservedGeneration reflects the generation of the most recently observed ReplicaSet. ## ReplicaSetList {#ReplicaSetList} ReplicaSetList is a collection of ReplicaSets.

- **apiVersion**: apps/v1 - **kind**: ReplicaSetList - **metadata** (}}">ListMeta) Standard list metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds - **items** ([]}}">ReplicaSet), required List of ReplicaSets. More info: https://kubernetes.io/docs/concepts/workloads/controllers/replicationcontroller ## Operations {#Operations}
