如何在集群升级之前正确更新清单的 apiVersion？

Question

所以我确实更新了清单并将 apiVersion: extensions/v1beta1 替换为 apiVersion: apps/v1

apiVersion: apps/v1
kind: Deployment
metadata:
  name: secretmanager
  namespace: kube-system
spec:
  selector:
    matchLabels:
      app: secretmanager
  template:
    metadata:
      labels:
        app: secretmanager
    spec:
    ...

然后我应用了更改

k apply -f deployment.yaml

Warning: kubectl apply should be used on resource created by either kubectl create --save-config or kubectl apply
deployment.apps/secretmanager configured

我也试过

k replace --force -f deployment.yaml

这重新创建了 POD（停机时间：（），但如果您尝试输出部署的 yaml 配置，我仍然会看到旧值

k get deployments -n kube-system secretmanager -o yaml 

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  annotations:
    deployment.kubernetes.io/revision: "1"
    kubectl.kubernetes.io/last-applied-configuration: |
      {"apiVersion":"apps/v1","kind":"Deployment",
      "metadata":{"annotations":{},"name":"secretmanager","namespace":"kube-system"}....}
  creationTimestamp: "2020-08-21T21:43:21Z"
  generation: 2
  name: secretmanager
  namespace: kube-system
  resourceVersion: "99352965"
  selfLink: /apis/extensions/v1beta1/namespaces/kube-system/deployments/secretmanager
  uid: 3d49aeb5-08a0-47c8-aac8-78da98d4c342
spec:

所以我仍然看到这个 apiVersion: extensions/v1beta1

我做错了什么？

我正在准备将 eks kubernetes v1.15 迁移到 v1.16

Deploymentexists in multiple apiGroups，所以是模棱两可的。尝试指定例如apps/v1 与：

kubectl get deployments.v1.apps

你应该看到你的Deployment，但是apps/v1 apiGroup。
