I have installed two nodes kubernetes 1.12.1 in cloud VMs, both behind internet proxy. Each VMs have floating IPs associated to connect over SSH, kube-01 is a master and kube-02 is a node. Executed export:
no_proxy=127.0.0.1,localhost,10.157.255.185,192.168.0.153,kube-02,192.168.0.25,kube-01before running kubeadm init, but I am getting the following status for kubectl get nodes:
NAME STATUS ROLES AGE VERSION
kube-01 NotReady master 89m v1.12.1
kube-02 NotReady <none> 29s v1.12.2Am I missing any configuration? Do I need to add 192.168.0.153 and 192.168.0.25 in respective VM's /etc/hosts?
Try with this
Your coredns is in pending state check with the networking plugin you have used and check the proper addons are added
check kubernates troubleshooting guide
https://kubernetes.io/docs/concepts/cluster-administration/addons/
And install the following with those
And check
kubectl get pods -n kube-systemOn the off chance it might be the same for someone else, in my case, I was using the wrong AMI image to create the nodegroup.
Looks like pod network is not installed yet on your cluster . You can install weave for example with below command
kubectl apply -f "https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d '\n')"After a few seconds, a Weave Net pod should be running on each Node and any further pods you create will be automatically attached to the Weave network.
You can install pod networks of your choice . Here is a list
after this check
$ kubectl describe nodescheck all is fine like below
Conditions:

You can also use journalctl on systemd to check kubelet errors.
$ journalctl -u kubelet
