Hi,

It could be due to https://github.com/flannel-io/flannel/issues/1155. One way to find out is to restart all the flannel pods after the cluster has been created,

kubectl -n kube-system delete pod -l app=flannel

Hope this helps.

Regards, Jake

Hi, I don't have any experience in kubernetes yet, my goal in the present is to test that the auto-sacele of a kubernetes cluster is working properly using magnum.

I followed some tutorials to get the test done. I tried to configure the test but I had problems with magnum-metrics-server not being able to provide metrics, after digging and reading a lot of things on the web, I found out that kubernetes master couldn't connect to the metrics server (curl -k https://ip_metrics_server https://ip_metrics_server didn't work) So I created another template but this time using calico as a network provider, and this time it worked.

How can I find why flannel does not work? where should I look?

Regards.
