After installing kubernetes cluster following this guide I decided to check logs of system pod kube-scheduler to ensure that all works fine:

 kubectl logs --namespace kube-system kube-scheduler-user223225-pc

but I got next error message:

Error from server: Get https://10.2.2.131:10250/containerLogs/kube-system/kube-scheduler-user-pc/kube-scheduler: dial tcp 10.2.2.131:10250: getsockopt: no route to host

I try to get logs from other pods and got the same error.

I run the cluster on Ubuntu 16.04 and chose flannel network installed using the next commands:

kubectl taint nodes --all node-role.kubernetes.io/master-
kubectl create -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel-rbac.yml
kubectl create --namespace kube-system -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

Maybe, I missed something, also I see people suggest to configure firewall but it didn't help me:

sudo systemctl stop kubelet
sudo systemctl stop docker
sudo ifconfig cni0 down
sudo ifconfig flannel.1 down
sudo ifconfig docker0 down

sudo service docker start
sudo service kubelet start

sudo iptables -A FORWARD -i cni0 -j ACCEPT
sudo iptables -A FORWARD -o cni0 -j ACCEPT

Does someone know how to fix the issue with getting logs? Thank you in advance.
