Chapter 16. ReplicaSet [apps/v1] Description ReplicaSet ensures that a specified number of pod replicas are running at any given time. Type object 16.1. 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 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 object ReplicaSetSpec is the specification of a ReplicaSet. status object ReplicaSetStatus represents the current status of a ReplicaSet. 16.1.1. .spec Description ReplicaSetSpec is the specification of a ReplicaSet. Type object Required selector Property Type Description minReadySeconds integer 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) replicas integer 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 selector LabelSelector 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 16.1.2. .status Description ReplicaSetStatus represents the current status of a ReplicaSet. Type object Required replicas Property Type Description availableReplicas integer The number of available replicas (ready for at least minReadySeconds) for this replica set. conditions array Represents the latest available observations of a replica set's current state. conditions[] object ReplicaSetCondition describes the state of a replica set at a certain point. fullyLabeledReplicas integer The number of pods that have labels matching the labels of the pod template of the replicaset. observedGeneration integer ObservedGeneration reflects the generation of the most recently observed ReplicaSet. readyReplicas integer readyReplicas is the number of pods targeted by this ReplicaSet with a Ready Condition. replicas integer Replicas is the most recently observed number of replicas. More info: https://kubernetes.io/docs/concepts/workloads/controllers/replicationcontroller/#what-is-a-replicationcontroller 16.1.3. .status.conditions Description Represents the latest available observations of a replica set's current state. Type array 16.1.4. .status.conditions[] Description ReplicaSetCondition describes the state of a replica set at a certain point. Type object Required type status Property Type Description lastTransitionTime Time The last time the condition transitioned from one status to another. message string A human readable message indicating details about the transition. reason string The reason for the condition's last transition. status string Status of the condition, one of True, False, Unknown. type string Type of replica set condition. 16.2.

Valid values are: - All: all dry run stages will be processed fieldValidation string fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present.
