将发布策略从 batch 切换到canary 报错

[542928492]

kruise-rollout（V0.5.0） : v1beta1
我预期从发布策略从 batch 切换到canary 。执行apply报错

这个是batch策略的yaml配置
`[root@k8s 240119]# kubectl get rollouts.rollouts.kruise.io hello0119canary -o yaml

    下面是预期切换的 canary策略yaml。 执行命令为 kubectl apply -f [root@k8s 240119]# cat hello0119canary-rollout.yaml

我貌似只能删除重建？！
kubectl delete rollouts.rollouts.kruise.io hello0119canary

• kubectl delete rollouts.rollouts.kruise.io hello0119canary
  rollout.rollouts.kruise.io "hello0119canary" deleted

[root@k8s 240119]# kubectl apply -f hello0119canary-rollout.yaml

• kubectl apply -f hello0119canary-rollout.yaml
  rollout.rollouts.kruise.io/hello0119canary created
