错误：添加选择器后，`selector` 与模板`labels` 不匹配

Question

我正在尝试部署这个 kubernetes 部署；但是，当我这样做时：kubectl apply -f es-deployment.yaml它会抛出错误：Error: `selector` does not match template `labels
我已经尝试在规范部分下添加选择器，matchLabels，但似乎这不起作用。下面是我的 yaml 文件。

您的标签和选择器放错了位置。

首先，您需要指定部署将控制哪些 Pod：

spec:
  replicas: 1
  selector: 
    matchLabels:
      app: elasticsearchconnector

然后你需要正确标记 pod：

  template:
    metadata:
      annotations:
        kompose.cmd: kompose convert -f docker-compose.yaml --volumes hostPath
        kompose.version: 1.19.0 (f63a961c)
      creationTimestamp: null
      labels:
        io.kompose.service: elasticsearchconnector
        app: elasticsearchconnector
    spec:
      containers:
