多个资源内容的修改、删除、新增

参数：JSON数组

疑惑：

kubectl patch pod valid-pod -p '{"spec":{"containers":[{"name":"kubernetes-serve-hostname","image":"new image"}]}}'

在K8s版本为1.13上，使用这种方式修改更新资源，却提示unpatch

kubernetes-client/java操作Patch

CoreV1Api apiInstance = new CoreV1Api();
String name = "主机名称"; // String | name of the Node
// 新增
V1Patch body = new V1Patch("[{\"op\": \"add\", \"path\": \"/metadata/labels/MixedDeploy_Status\", \"value\":\"true\"}]");
// 替换更新
V1Patch body = new V1Patch("[{\"op\": \"replace\", \"path\": \"/metadata/labels/MixedDeploy_Status\", \"value\":\"false\"}]");
String pretty = "true";
String dryRun = null;
Boolean force = true; // 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.
try {
    V1Node result = apiInstance.patchNode(name, body, pretty, dryRun, null, force);
    System.out.println(result);
} catch (ApiException e) {
    System.err.println("Exception when calling CoreV1Api#patchNode");
    e.printStackTrace();
