Problem
Kubernetes Addons - weave second/slaves pods are not starting up after executing kubeadm join command in the slave machines. weave pods status is CrashLoopBackOff
Cause
Network interface is not configured with "High" network configuration. eth0 is not enabled due to low/moderate network interface configuration for an instance.
Fix
Provision the aws instances with "High" network interface configuration (In Aws console, specific instance configuration network interface should be eth0). Kubernetes cni (weave) network will use the ethernet to start the cluster(Result: slave node status will be "Ready").
