库伯内特斯吊舱部署没有更新

Question

我有一个由makefile通过命令make deploy IMG=my_azure_repo/egress-operator:v0.1创建的pod make deploy IMG=my_azure_repo/egress-operator:v0.1。

​

这个豆荚在描述中显示了unexpected status: 401 Unauthorized错误，所以我创建了imagePullSecrets，并试图通过创建pod的deployment.yaml egress-operator-manager.yaml文件来用秘密更新这个pod。

但是，当我应用这个yaml文件时，它给出了以下错误：

root@Ubuntu18-VM:~/egress-operator# kubectl apply -f /home/user/egress-operator-manager.yaml
The Deployment "egress-operator-controller-manager" is invalid: spec.selector: Invalid value:
 v1.LabelSelector{MatchLabels:map[string]string{"moduleId":"egress-operator"}, 
MatchExpressions:[]v1.LabelSelectorRequirement(nil)}: field is immutable

egress-operator-manager.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: egress-operator-controller-manager
  namespace: egress-operator-system
  labels:
    moduleId: egress-operator
spec:
  replicas: 1
  selector:
    matchLabels:
      moduleId: egress-operator
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
        moduleId: egress-operator
    spec:
      containers:
        - image: my_azure_repo/egress-operator:v0.1
          name: egress-operator
      imagePullSecrets:
        - name: mysecret

可以让我知道如何更新这个吊舱的deployment.yaml吗？

删除部署一次，并尝试应用YAML。

这可能是由于K8s服务不允许滚动更新一旦部署，标签选择器 of K8s服务无法更新，直到您决定删除现有的部署

Changing selectors leads to undefined behaviors - users are not expected to change the selectors
