Here I briefly discuss how to deploy cxy-sdn along with Kubernetes, tested on Kubernetes 1.1.2
First, cxy-sdn has two parts: client side(cxy_sdn, bash script) and a server side(advanced network management and configuration tool wrapped in a docker image which name is registry.aliyuncs.com/wizardcxy/cxy-sdn)
Deploy procedure on every Kubernetes minion node:
1 $ sudo mkdir -p /usr/libexec/kubernetes/kubelet-plugins/net/exec/cxy~cxy_sdn/ && sudo cp cxy_sdn /usr/libexec/kubernetes/kubelet-plugins/net/exec/cxy~cxy_sdn/.
2 $ sudo ./cxy_sdn agent start (you may first meet all the dependencies by run $ sudo ./cxy_sdn deps). If it is the first node, hit 'y' and continue, else hit 'n' and use '$ sudo ./cxy_sdn cluster join $THE_FIRST_NODE_IP
3 Add cmd option '--network-plugin=cxy/cxy_sdn' for kubelet and restart kubelet.
4 Check kubelet log to see if the plugin is correctly loaded.
5 $ sudo ./cxy_sdn agent logs to see if cxy_sdn works well.
