flanneld binary is quite large

[tomdee]

The flanneld binary got quite large when we added the kube-subnet-mgr (which imports a lot of code to get a k8s client). It would be nice to get the size back down, some options are:

• Start using https://github.com/kubernetes/client-go
• Start using https://github.com/ericchiang/k8s

Even with the move to client-go the binary is still ~52MB

I think to make them smaller we'd need to use upx (and maybe some stripping)

A crazier option would be shipping different binaries for k8s vs etcd backed flanneld.
