Question

kubectl commands trying to use private IPs

Posted April 23, 2019 811 views

Assorted kubectl commands (getting logs, trying to exec a shell on a container), fail with an i/o timeout because they are trying to connect over the private ip.

Ex:

Error from server: Get https://10.136.191.197:10250/containerLogs/kube-system/csi-do-node-ttr6h/csi-do-plugin: dial tcp 10.136.191.197:10250: i/o timeout

Is there some config somewhere I need to change to get kubectl to stop trying to use the private IPs? I haven’t installed any networking plugins but it looks like Cilium comes installed by default, with DO managed k8s.

Hello,

You only need to download the cluster configuration file which you get during the creation of the cluster by clicking Actions and Download Config from the cluster home page. I’ve tried connecting to a pod and it seems to work fine.

Another thing that you might have to keep in mind is that you might have to open the port that you are trying to connect to for outgoing TCP traffic.
