ReplicationController represents the configuration of a replication controller.
| Field | 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: http://releases.k8s.io/HEAD/docs/devel/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: http://releases.k8s.io/HEAD/docs/devel/api-conventions.md#types-kinds |
| metadata ObjectMeta |
If the Labels of a ReplicationController are empty, they are defaulted to be the same as the Pod(s) that the replication controller manages. Standard object's metadata. More info: http://releases.k8s.io/HEAD/docs/devel/api-conventions.md#metadata |
| spec ReplicationControllerSpec |
Spec defines the specification of the desired behavior of the replication controller. More info: http://releases.k8s.io/HEAD/docs/devel/api-conventions.md#spec-and-status |
| status ReplicationControllerStatus |
Status is the most recently observed status of the replication controller. This data may be out of date by some window of time. Populated by the system. Read-only. More info: http://releases.k8s.io/HEAD/docs/devel/api-conventions.md#spec-and-status |
ReplicationControllerSpec v1
| Field | 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: http://kubernetes.io/docs/user-guide/replication-controller#what-is-a-replication-controller |
| selector object |
Selector is a label query over pods that should match the Replicas count. If Selector is empty, it is defaulted to the labels present on the Pod template. Label keys and values that must match in order to be controlled by this replication controller, if empty defaulted to labels on Pod template. More info: http://kubernetes.io/docs/user-guide/labels#label-selectors |
| template PodTemplateSpec |
Template is the object that describes the pod that will be created if insufficient replicas are detected. This takes precedence over a TemplateRef. More info: http://kubernetes.io/docs/user-guide/replication-controller#pod-template |
ReplicationControllerStatus v1
| Field | Description |
|---|---|
| availableReplicas integer |
The number of available replicas (ready for at least minReadySeconds) for this replication controller. |
| conditions ReplicationControllerCondition array |
Represents the latest available observations of a replication controller's current state. |
| fullyLabeledReplicas integer |
The number of pods that have labels matching the labels of the pod template of the replication controller. |
| observedGeneration integer |
ObservedGeneration reflects the generation of the most recently observed replication controller. |
| readyReplicas integer |
The number of ready replicas for this replication controller. |
| replicas integer |
Replicas is the most recently oberved number of replicas. More info: http://kubernetes.io/docs/user-guide/replication-controller#what-is-a-replication-controller |
ReplicationControllerList v1
| Field | Description |
|---|---|

| items ReplicationController array |
List of replication controllers. More info: http://kubernetes.io/docs/user-guide/replication-controller |
| 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: http://releases.k8s.io/HEAD/docs/devel/api-conventions.md#types-kinds |
