Chapter 5. Scale [autoscaling/v1] Description Scale represents a scaling request for a resource. Type object 5.1. 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.

Type object Property Type Description replicas integer replicas is the desired number of instances for the scaled object. 5.1.2. .status Description ScaleStatus represents the current status of a scale subresource. Type object Required replicas Property Type Description replicas integer replicas is the actual number of observed instances of the scaled object. selector string selector is the label query over pods that should match the replicas count. This is same as the label selector but in the string format to avoid introspection by clients. The string will be in the same format as the query-param syntax. More info about label selectors: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/ 5.2. API endpoints The following API endpoints are available: /apis/apps/v1/namespaces/{namespace}/deployments/{name}/scale GET : read scale of the specified Deployment PATCH : partially update scale of the specified Deployment PUT : replace scale of the specified Deployment /apis/apps/v1/namespaces/{namespace}/replicasets/{name}/scale GET : read scale of the specified ReplicaSet PATCH : partially update scale of the specified ReplicaSet PUT : replace scale of the specified ReplicaSet /apis/apps/v1/namespaces/{namespace}/statefulsets/{name}/scale GET : read scale of the specified StatefulSet PATCH : partially update scale of the specified StatefulSet PUT : replace scale of the specified StatefulSet /api/v1/namespaces/{namespace}/replicationcontrollers/{name}/scale GET : read scale of the specified ReplicationController PATCH : partially update scale of the specified ReplicationController PUT : replace scale of the specified ReplicationController 5.2.1. /apis/apps/v1/namespaces/{namespace}/deployments/{name}/scale Table 5.1. Global path parameters Parameter Type Description name string name of the Scale namespace string object name and auth scope, such as for teams and projects Table 5.2. Global query parameters Parameter Type Description pretty string If 'true', then the output is pretty printed. HTTP method GET Description read scale of the specified Deployment Table 5.3. HTTP responses HTTP code Reponse body 200 - OK Scale schema 401 - Unauthorized Empty HTTP method PATCH Description partially update scale of the specified Deployment Table 5.4. Query parameters Parameter Type Description dryRun string When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed fieldManager string fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint . This field is required for apply requests (application/apply-patch) but optional for non-apply patch types (JsonPatch, MergePatch, StrategicMergePatch). 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. The error returned from the server will contain all unknown and duplicate fields encountered. force boolean Force is going to "force" Apply requests. It means user will re-acquire conflicting fields owned by other people. Force flag must be unset for non-apply patch requests. Table 5.5.
