prouser@master:~/yaml$ k apply -f http-go-rc-v2.yaml
Warning: resource replicationcontrollers/http-go is missing the kubectl.kubernetes.io/last-applied-configuration annotation which is required by kubectl apply. kubectl apply should only be used on resources created declaratively by either kubectl create --save-config or kubectl apply. The missing annotation will be patched automatically.
replicationcontroller/http-go configured
이런식으로 Warning 이 발생했는데, 어떤 것 때문에 이런 Warning이 발생하나요?
