Kubernetes:错误kubectl编辑部署

我试图通过以下方式编辑kubernetes中的部署：

kubectl -n <namespace> edit deployment <depolyment_name>.

有人能帮忙吗

已附加apiserver的编辑部署文件：

kubectl-n联合系统编辑部署apiserver

（****之间的代码是我添加的行）

我正在尝试在联合API中配置准入控制器

谢谢

  dnsPolicy: ClusterFirst
  # DELETE imagePullSecrets:
  # DELETE - {}
  restartPolicy: Always

---

我强烈建议删除

imagePullSecrets

块。由于这些对象的mergeKey为

名称

，但该对象没有

名称

，因此很容易导致您遇到的错误。如果YAML是在这种情况下提供给您的编辑器的，那么我几乎可以肯定这是一个kubernetes错误：它应该总是（？）允许通过

kubectl edit

往返YAML，如果没有其他原因的话，就是在这种情况下。

编辑它之后，它有一个语法错误。您需要为任何人粘贴部署内容以帮助IDK，configmap看起来不错，可能是额外的

volumeMounts

键，而不是它下面的项目？我尝试了这两种方法。我不确定是语法错误，因为这个问题也是当我试图改变名称或端口或其他东西。你设法解决你的问题？在这种情况下，请考虑把这个答案标记为正确的，因为它会帮助别人知道（a）你的问题得到解决（b）看看这里，如果他们有类似的问题，在这种情况下，kubectl是否编辑了YAML文件？我想知道我们是否需要查找或打开kubernetes发送“非法”YAMLW的bug在那种情况下是什么意思？包含错误内容

imagePullSecrets:\n-{}\n

删除imagePullSecrets后：\n-{}\n通过联盟控制平面连接到群集的连接已断开。可能与这一变化有关？类似于kubectl get namespace/get cluster的命令返回未找到资源，并且控制器管理器容器上存在错误：
