Kubernetes NodePortで30000~32767以外のポートも割り当てられるようにする(Microk8s)

背景

KuberentesのNodePortは、デフォルトでは30000~32767以外のポートは割当できない用に設定されている。

それ以外のポート(8080)を割り当てたいときには、設定変更が必要

解決方法

kubernetesのマスターノードを変更できる環境であることが必須

  • GKE などではおそらく不可

kube-apiserver のオプションである--service-node-port-rangeを有効にする

例: Microk8s

/var/snap/microk8s/current/args/kube-apiserver
....(略)...

# 次の1行を追加する                                                                    
# --service-node-port-range <from>-<to>   

--service-node-port-range 2000-32767       

書き換えたら、microk8sを再起動

sudo systemctl restart snap.microk8s.daemon-apiserver.service
