pod to pod communication
Hello, I cannot communicate with the worker node from the master node and vice versa? This might be my problem. How should the ip be in the calico file? I have the 192.168.0.0/16 ip address that is how I left it, I had it with my master node ip and it still would not work. I cant communicate between the pods and I am not sure which ip address i should use. The node ip, docker ip, public ip. I cant ping and it crashes when I try to use kubeadm upgrade node
[upgrade] Reading configuration from the cluster... [upgrade] FYI: You can look at this config file with 'kubectl -n kube-system get cm kubeadm-config -oyaml' unable to fetch the kubeadm-config ConfigMap: failed to get config map: Get "https://k8smaster:6443/api/v1/namespaces/kube-system/configmaps/kubeadm-config?timeout=10s": dial tcp 10.2.0.20:6443: connect: no route to host To see the stack trace of this error execute with --v=5 or highe
I think this is the reason certain things cant be found, I can't ping the master or worker. no route to host. I will try 10.2.0.0/16 that is what i have my instances in gce set for.
