Kubernetesでpodが起動しない_controllerがおかしい

node2がCrashLoopBackOffするのが治ったと思ったら今度は、controllerがおかしい

[root@master ~]# kubectl get pod -n metallb-system -o wide
NAME                          READY   STATUS              RESTARTS   AGE   IP              NODE     NOMINATED NODE

kubectl describe nodesでcontrollerの確認

failed to set bridge addr: "cni0" already has an IP address

IPをすでに持っていると、、 このエラー内容で検索 qiita.com によると、以下コマンドで削除のflannel削除の必要あり。 ip link delete flannel.1 , ip link delete cni0

うまくいきました。

bootcampできました。

ちょっと感動した。実はダッシュボードの設定とかうまくいってないので、もうちょっと頑張ります。。
