10. Podネットワークの割り当て

ノード間のPod同士で通信を行うためのルートを作成します。

ルーティングテーブルの作成

KUBE_W01_IP=$(grep kube-w01 machines.txt | cut -d " " -f 1)
KUBE_W01_SUBNET=$(grep kube-w01 machines.txt | cut -d " " -f 4)
KUBE_W02_IP=$(grep kube-w02 machines.txt | cut -d " " -f 1)
KUBE_W02_SUBNET=$(grep kube-w02 machines.txt | cut -d " " -f 4)

ssh nob@kube-c01 "sudo ip route add ${KUBE_W01_SUBNET} via ${KUBE_W01_IP}"
ssh nob@kube-c01 "sudo ip route add ${KUBE_W02_SUBNET} via ${KUBE_W02_IP}"

ssh nob@kube-w01 "sudo ip route add ${KUBE_W02_SUBNET} via ${KUBE_W02_IP}"

ssh nob@kube-w02 "sudo ip route add ${KUBE_W01_SUBNET} via ${KUBE_W01_IP}"
