How to troubleshoot if restart deployment but nothing happens with no event, not creating replicasets, not creating pods?

I think issue of kube-api-load-balancer → kube-apiserver → etcd, right?

Many thanks.

How Can I know the kubectl command has been reached “kube-apiserver”?

#4

Alex Novik:
if you restarted deployment api-server is working

#5

Alex Novik:
kubectl talking to api-server, any positive output means it is working

#6

K8s_Member:
The problem is when I run restart deploy, nothing happens. Even if when I run kubectl describe deployment... have no Events.

#7

K8s_Member:
No replicasets, no pods

#8

Alex Novik:
check journalctl -xu kube-apiserver

#9

Alex Novik:
kubectl get pods, get nodes the same?

#10

K8s_Member:
Those things have values, so I think that kube-apiserver is working fine.
