Kubernetes version: 1.11.1
Cloud being used: bare-metal (running on GCE, but installed from scratch)
Host OS: Ubuntu 16.04
CNI and version: Canal 3.8
CRI and version: Docker 18.06.1-ce
I have a following problem:
I have setup a k8s cluster locally using kubeadm. Now I want to join a node from a remote network in that local cluster.
I was able to join the node with the appropriate
kubeadm init ...(with correct public IP addresses of master node for flags
But now, pods on that remote node cannot be reached.
Eg. I try,
kubectl --namespace=kube-system logs canal-b9dhq calico-node where
canal-b9dhq is a pod on a remote node, but I get:
Error from server: Get https://10.128.0.2:10250/containerLogs/kube-system/canal-b9dhq/calico-node: dial tcp 10.128.0.2:10250: i/o timeout
where 10.128.0.2 is an local IP address of a remote node in its own local network.
All ports are open in both networks. I’m using NodePort and Canal (kubectl apply -f https://docs.projectcalico.org/v3.8/manifests/canal.yaml).
Actually, both machines are VMs in GCP, in separate VPCs.
I cannot even debug this since, as can be seen from the error above, I cannot even get the logs of the pods on a remote node …
But, I can manually ssh to a remote node and see the logs using docker logs … For Calico pod, there are a lot of INFO logs which I assume confirms that there is communication between the master and the remote node.
Can anyone help?
