禁止：禁止更新“replicas”、“template”和“update strategy”以外的字段的statefulset规范

Question

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<Deployment, DeploymentList, DoneableDeployment, ScalableResource<Deployment, DoneableDeployment>> deployments = client.extensions().deployments().inNamespace(namespace);
  Deployment result = deployments.createOrReplace(deployment);
  logger.info(String.format("Created/Replaced Deployment [%s].", result.getMetadata().getName()));
}

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<StatefulSet, StatefulSetList, DoneableStatefulSet, RollableScalableResource<StatefulSet, DoneableStatefulSet>> statefulSets = client.apps().statefulSets().inNamespace(namespace);
  StatefulSet result = statefulSets.createOrReplace(statefulSet);
  logger.info(String.format("Created/Replaced StatefulSet [%s].", result.getMetadata().getName()));
}

执行失败：PUT在:https://kubernetes.default.svc/apis/apps/v1beta1/namespaces/itsma1/statefulsets/pro-rabbitmq。消息：statefulset.apps“Pro-RabbitMQ”无效：spec：Piopbed：禁止更新“replicas”、“template”和“update strategy”以外的字段的statefulset spec。接收状态：Status(APIVersion=v1,代码=422,details=statusdetails(causes=[statuscause(field=spec,message=biabled：禁止对“replicas”、“template”和“update strategy”以外的字段更新statefulset规范。,reason=fieldvaluebiabled,additionalproperties={}）],group=apps,kind=statefulset,name=pro-rabbitmq,retryafterseconds=null,uid=null,additionalproperties={}）,kind=statefulset。apps“pro-rabbitmq”无效：spec：biabled：对“replicas禁止”replicas“、”template“与”update strategy“以外得字段.,Metadata=ListMeta(ResourceVersion=Null,Selflink=Null,AdditionalProperties={}）,Reason=Invalid,Status=Failure,AdditionalProperties={}）.

我很好奇为什么会发生错误，以及如何修复它。

Answer 1

您可以尝试这样做来更新StatefulSet

client.apps().StateFulSets().WithName（“repl1”）.Rolling（）.WithTimeout(5,TimeUnit.Minutes).UpdateImage（“”）；

如果只想缩放，可以试试这个
