I have a Ubuntu 16.04 which is acting as kubernetes master. I have installed kuber v1.13.1 and using weave for networking. I have 2 Raspberry pi devices running the same version of kubernetes. I created a cluster and joined the raspberry pi to Ubuntu kube master. I have started a deployment and everything looks to be working fine.

When I checked the logs of the container, I found out that it was not able to connect to the internet. I tried pinging but got no results. When I run the command to describe the pod, I got following:

Warning FailedCreatePodSandBox 42m (x3 over 42m) kubelet, node02 (combined from similar events): Failed create pod sandbox: rpc error: code = Unknown desc = failed to set up sandbox container "dea99f80488031b84b7b1f934343e54d877adf931071401651628505d52f55f9" network for pod "deployment-cnfc5": NetworkPlugin cni failed to set up pod "deployment-cnfc5_matrix-device" network: unable to allocate IP address: Post http://127.0.0.1:6784/ip/dea99f80488031b84b7b1f934343e54d877adf931071401651628505d52f55f9: dial tcp 127.0.0.1:6784: connect: connection refused

I have checked the directory /etc/cni/net.d and it contains 10-weave.conflist on both master and worker node. I have also checked the directory /opt/cni/bin and found below on master node:

bridge flannel ipvlan macvlan ptp tuning weave-ipam weave-plugin-2.5.1 dhcp host-local loopback portmap sample vlan weave-net

and on worker, I got below:

bridge flannel ipvlan macvlan ptp tuning weave-ipam weave-plugin-2.5.0 dhcp host-local loopback portmap sample vlan weave-net weave-plugin-2.5.1

Please can anyone please let me know what can I do to resolve this issue.? Thanks.

I initiated the kube master by using below commands:

sudo kubeadm init --token-ttl=0 --apiserver-advertise-address=192.168.0.142

and installed weave using:

kubectl apply -f "https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d '\n')"
