Example 25 with V1Node

use of io.kubernetes.client.openapi.models.V1Node in project java by kubernetes-client.

the class CoreV1Api method patchNodeWithHttpInfo.

/**
 * partially update the specified Node
 *
 * @param name name of the Node (required)
 * @param body (required)
 * @param pretty If 'true', then the output is pretty printed. (optional)
 * @param dryRun 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 (optional)
 * @param fieldManager 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). (optional)
 * @param fieldValidation fieldValidation determines how the server should respond to
 *     unknown/duplicate fields in the object in the request. Introduced as alpha in 1.23, older
 *     servers or servers with the `ServerSideFieldValidation` feature disabled will
 *     discard valid values specified in this param and not perform any server side field
 *     validation. Valid values are: - Ignore: ignores unknown/duplicate fields. - Warn: responds
 *     with a warning for each unknown/duplicate field, but successfully serves the request. -
 *     Strict: fails the request on unknown/duplicate fields. (optional)
 * @param force 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. (optional)
 * @return ApiResponse<V1Node>
 * @throws ApiException If fail to call the API, e.g. server error or cannot deserialize the
 *     response body
 * @http.response.details
 *     <table summary="Response Details" border="1">
 * <tr><td> Status Code </td><td> Description </td><td> Response Headers </td></tr>
 * <tr><td> 200 </td><td> OK </td><td>  -  </td></tr>
 * <tr><td> 201 </td><td> Created </td><td>  -  </td></tr>
 * <tr><td> 401 </td><td> Unauthorized </td><td>  -  </td></tr>
