禁止:禁止更新除“副本"，“模板"和"updateStrategy"以外的字段的有状态集规范 [英] Forbidden: updates to statefulset spec for fields other than 'replicas', 'template', and 'updateStrategy' are forbidden

问题描述

我使用io.fabric8.kubernetes-client版本3.1.8进行kubernetes资源的RollingUpdate.适合部署.但是我遇到了StatefulSet的例外.但是如果我对StatefulSet使用'kubectl apply -f ***.yaml'也很好.

I use io.fabric8.kubernetes-client, version 3.1.8 to do RollingUpdate of kubernetes resource. It is fine for Deployment. But I meet an exception for StatefulSet. But it is also fine if I use 'kubectl apply -f ***.yaml' for the StatefulSet.

RollingUpdate部署的代码:

Code to RollingUpdate Deployment:

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()));
}

RollingUpdate StatefulSet的代码

Code to 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<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()));
}

RollingUpdate of StatefulSet时发生异常

Exception when do RollingUpdate of StatefulSet

我很好奇为什么会发生错误以及如何解决该错误.

推荐答案

您可以尝试使用此方法来更新StatefulSet

You can try this to update the StatefulSet

client.apps().statefulSets().withName("repl1").rolling().withTimeout(5, TimeUnit.MINUTES).updateImage("");

client.apps().statefulSets().withName("repl1").rolling().withTimeout(5, TimeUnit.MINUTES).updateImage("");

如果只想缩放，可以尝试一下

If you want to only scale, you can try this

client.apps().statefulSets().withName("repl1").scale(5, true);

client.apps().statefulSets().withName("repl1").scale(5, true);
