Question

我正在尝试部署此kubernetes部署；但是，无论何时我做：kubectl apply -f es-deployment.yaml都会引发错误：Error: `selector` does not match template `labels
我已经尝试在specs部分下添加选择器matchLabels，但似乎不起作用。以下是我的yaml文件。

apiVersion: apps/v1
kind: Deployment
metadata:
  annotations:
    kompose.cmd: kompose convert -f docker-compose.yaml --volumes hostPath
    kompose.version: 1.19.0 (f63a961c)

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

然后您需要正确标记豆荚：

  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:

错误：添加选择器后，“选择器”与模板“标签”不匹配
