container real time logging does not work as expected

[rayzhou2017]

Describe the bug
Enable components in cluster configuration, and check the logs using

kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f

Also open the pod ks-installer container log and enable real time to compare the result. At first time, it works perfect fine, but after a while, the container real time logging seems to stop working as you can see from the screenshot below

Versions used(KubeSphere/Kubernetes)
KubeSphere: 3.0.0-dev

Please check if the apiserver is disconnected during the update.

aha, that is true. Changing cluster configuration will restart api server. Let me check the logs in other docker

[rayzhou2017]

It seems the problem does exist. I install a nginx pod, then in another pod to curl the nginx sevice. When enable real time logging the nginx, it does not show the access log. Then I disable the real time logging, the last time access logs pop up as you can see the 10.233.99.99 log.
