With weave-kube 2.0.1 and kubernetes 1.6.4, seeing a lot docker error logs

What you expected to happen?

no annoying docker error logs

What happened?

I have a kubernetes 1.6.4 cluster, previously I used weave-kube(and weave-npc) 1.9.7, then I upgraded weave to 2.0.1, with https://git.io/weave-kube, everything seems to keep working, but docker complains a lot:

Anything else we need to know?

I configured kubernetes with kubeadm.

I also installed weave-scope with kubectl apply --namespace kube-system -f "https://cloud.weave.works/k8s/scope.yaml?k8s-version=$(kubectl version | base64 | tr -d '\n')"

Versions:

$ kubectl version

reinstall weave-scope fixed this issue 😄

[inetfuture]

no, still happens...

[inetfuture]

if I uninstall weave-scope, these logs disappear

[bboreham]

Looks like weaveworks/scope#2634

[inetfuture]

ok, closing this
