K3S新增節點報錯

iXiAo9發表於2024-03-07

解決辦法：
在主節點/etc/systemd/system/k3s.service配置檔案中指定網路卡
ExecStart 之前：

ExecStart=/usr/local/bin/k3s \
    server \

ExecStart 之後：

ExecStart=/usr/local/bin/k3s \
    server --node-external-ip <這裡填寫對外的IP> \

使用以下命令在 master 上重新啟動 k3s，然後再次嘗試從節點加入主節點。

sudo systemctl daemon-reload
sudo systemctl restart k3s
