我使用io.fabric8.kubernetes-client，版本3.1.8来执行kubernetes资源的RollingUpdate . 它适用于部署 . 但我遇到StatefulSet的例外 . 但是如果我对StatefulSet使用'kubectl apply -f *** . yaml'也没关系 .

RollingUpdate部署代码：

public void createOrReplaceResourceByYaml(String namespace, KubernetesResource resource) {

KubernetesClient client = k8sRestClient.newKubeClient();

Deployment deployment = (Deployment) resource;

logger.info(String.format("Create/Replace Deployment [%s] in namespace [%s].", ((Deployment) resource).getMetadata().getName(), namespace));

NonNamespaceOperation> deployments = client.extensions().deployments().inNamespace(namespace);

Deployment result = deployments.createOrReplace(deployment);

logger.info(String.format("Created/Replaced Deployment [%s].", result.getMetadata().getName()));

}

代码到RollingUpdate StatefulSet

public void createOrReplaceResourceByYaml(String namespace, KubernetesResource resource) {

KubernetesClient client = k8sRestClient.newKubeClient();

StatefulSet statefulSet = (StatefulSet) resource;

logger.info(String.format("Create/Replace StatefulSet [%s] in namespace [%s].", statefulSet.getMetadata().getName(), namespace));

NonNamespaceOperation> statefulSets = client.apps().statefulSets().inNamespace(namespace);

StatefulSet result = statefulSets.createOrReplace(statefulSet);

logger.info(String.format("Created/Replaced StatefulSet [%s].", result.getMetadata().getName()));

}

执行StatefulSet的RollingUpdate时出现异常

执行失败：PUT at：https：//kubernetes.default.svc/apis/apps/v1beta1/namespaces/itsma1/statefulsets/pro-rabbitmq . 消息：StatefulSet.apps“pro-rabbitmq”无效：spec：Forbidden：禁止对'replicas'，'template'和'updateStrategy'以外的字段更新statefulset规范 . 收到状态：状态(apiVersion = v1， code = 422，details = StatusDetails(cause = [StatusCause(field = spec，message = Forbidden：禁止对'replicas'，'template'和'updateStrategy'以外的字段更新statefulset规范 . ，reason = FieldValueForbidden，additionalProperties = {})]，group = apps，kind = StatefulSet，name = pro-rabbitmq，retryAfterSeconds = null，uid = null，additionalProperties = {})，kind = Status，message = StatefulSet.apps“pro-rabbitmq”无效：spec：Forbidden：禁止对'replicas'，'template'和'updateStrategy'以外的字段更新statefulset规范 . ，metadata = ListMeta(resourceVersion = null，selfLink = null，additionalProperties = {})，reason = Invalid ，status = Failure，additionalProperties = {}) .

I am curious why the error happened and how to fix it.
