K3S for raspberry pi

◻️master&node側でk3sのインストールを行う。

wget https://github.com/rancher/k3s/releases/download/v0.3.0/k3s-armhf && \

chmod +x k3s-armhf && \

sudo mv k3s-armhf /usr/local/bin/k3s

◻️master側で実施

root@rasp01:~# sudo cat /var/lib/rancher/k3s/server/node-token

K10f6b6658c57b3746e62e66cf97d5d44357f9a552da862204e1c7d22fb75f6ee12::node:8fa426db4b28657934d8be98eb023345

◻️node側で実施

export NODE_TOKEN="K10f6b6658c57b3746e62e66cf97d5d44357f9a552da862204e1c7d22fb75f6ee12::node:8fa426db4b28657934d8be98eb023345"

$ export SERVER_IP="https://192.168.13.2:6443"

$ sudo -E k3s agent -s ${SERVER_IP} -t ${NODE_TOKEN}

<master側のIP>

https://192.168.13.2:6443

◻️master側で以下のコマンドを実施してみると、node側と同期できていることが分かる。

root@rasp01:~# sudo k3s kubectl get node -o wide
