git clone [email protected]:charlesmchan/rainier.git

cd rainier
go build rainier.go

sudo mkdir -p /etc/cni/net.d
sudo mkdir -p /opt/cni/bin
sudo ln -s config /etc/cni/net.d/rainier.conf
sudo ln -s rainier /opt/cni/bin/rainier

sudo kubectl create -f service.yaml

service.yaml will spawn 3 busybox containers. All of them should get an IP address and should be able to ping one another if OVS is set to standalone mode

Kubernetes does not take DNS configuration returned from CNI. We need to configure DNS in the Kubernetes pod configuration

I have a bad sense of naming a project and I was eating rainier cherries while coding
