What happened?

I am looking into the possibility of replacing Flannel with Weave Net. I assumed it would be fairly straight forward, but I am running into some issues...

I made the following changes:

• edited the security groups (Weave Net uses ports 6783 & 6784)
• in modules/bootkube/resources/manifests/ I replaced the kube-flannel.yml (DaemonSet) with kube-weave.yml
• some minor changes in kubelet.service (for example: that /etc/cni/net.d/ is used instead of /etc/kubernetes/cni/net.d/)

At first everything seemed to be working (kubectl get nodes showed that all nodes were "Ready"), unfortunately all of the api, controller and dns pods remain in the "ContainerCreating" state...

When describing one of those pods in "ContainerCreating" state I get:

  48m	1s	2086	kubelet, ip-10-0-38-214.us-east-2.compute.internal		Warning	FailedSync	Error syncing pod, skipping: failed to "CreatePodSandbox" for "kube-controller-manager-3857991999-llxmh_kube-system(077bb534-670e-11e7-98e9-0295e4ade107)" with CreatePodSandboxError: "CreatePodSandbox for pod \"kube-controller-manager-3857991999-llxmh_kube-system(077bb534-670e-11e7-98e9-0295e4ade107)\" failed: rpc error: code = 2 desc = NetworkPlugin cni failed to set up pod \"kube-controller-manager-3857991999-llxmh_kube-system\" network: open /run/flannel/subnet.env: no such file or directory"

Although I have not installed/configured flannel it show up in the logs... Anybody an idea what I am missing? Or what I can try? I want to do all legwork to get this implemented, just needs a gentle push into the right direction.

Thanks for the request. Closing b/c duplicate.

We may look into supporting other CNI implementations in the future, but that is not currently supported.
