title: weave cni is not assigning ip address to weave bridge with in the node cidr in k8s
body: <p>I'm trying to bootstrap the k8s cluster using weave as cni plugin which was originally configured without --pod-cidr and weave plugin</p>
  
  <pre><code>root@kube1:/etc/systemd/system/kubelet.service.d# kubectl get no
  NAME    STATUS   ROLES    AGE   VERSION
  kube1   Ready    master   31m   v1.18.2
  kube2   Ready    &lt;none&gt;   30m   v1.18.2
  kube3   Ready    &lt;none&gt;   31m   v1.18.2
  root@kube1:/etc/systemd/system/kubelet.service.d# 
  </code></pre>
  
  <p>So i have done the cleanup using the below commands</p>
  
  <pre><code> kubectl drain kube2 --delete-local-data --force --ignore-daemonsets
   kubectl drain kube3 --delete-local-data --force --ignore-daemonsets
   kubectl drain kube1 --delete-local-data --force --ignore-daemonsets
  
   kubectl delete no kube1 kube2 kube3
  
   kubeadm reset
  
   curl -L git.io/weave -o /usr/local/bin/weave
   chmod a+x /usr/local/bin/weave
   kubeadm reset
   weave reset --force
  
   rm /opt/cni/bin/weave-*
  
   iptables -P INPUT ACCEPT
   iptables -P FORWARD ACCEPT
   iptables -P OUTPUT ACCEPT
   iptables -t nat -F
   iptables -t mangle -F
   iptables -F
   iptables -X
   systemctl restart docker
  </code></pre>
  
  <p>i have ensured the weave bridge interface was deleted on all 3 nodes and re initiated the cluster   </p>
  
  <pre><code>  kubeadm init --apiserver-advertise-address=192.168.56.101 --pod-network-cidr=10.244.0.0/16 --service-cidr=10.100.0.0/16
  </code></pre>
  
  <p>I have ensured  the node-cidr was allocated to worker nodes(pod-cidr - 10.244.0.0./16) as below</p>
  
  <pre><code>root@kube1:/etc/systemd/system/kubelet.service.d# kubectl get no kube2 -o yaml|grep -i podCIDR|grep -i 24
    podCIDR: 10.244.2.0/24
  
  root@kube1:/etc/systemd/system/kubelet.service.d# kubectl get no kube3 -o yaml|grep -i podCIDR|grep -i 24
    podCIDR: 10.244.1.0/24
  </code></pre>
  
  <p>After i have created the weave pod's ,i was expecting to see the weave bridge interface ip in 10.244.* but it created with default weave configuration (10.32.0.1) it seems</p>
  
  <pre><code>root@kube2:/etc/kubernetes# ifconfig weave
  weave: flags=4163&lt;UP,BROADCAST,RUNNING,MULTICAST&gt;  mtu 1376
          inet 10.32.0.1  netmask 255.240.0.0  broadcast 10.47.255.255
          inet6 fe80::187b:63ff:fe5c:a2ae  prefixlen 64  scopeid 0x20&lt;link&gt;
          ether 1a:7b:63:5c:a2:ae  txqueuelen 1000  (Ethernet)
  </code></pre>
  
  <p>Is there anything i have missed to clean up? or is it weave plugins default behaviour? </p>
