MicroK8s : インストール2021/05/13 |
Canonical 社発の軽量 Kubernetes 環境 [MicroK8s] をインストールします。
|
[1] | Snappy から MicroK8s をインストールします。 Snappy は Ubuntu サーバー デフォルトでインストールされ、自動起動していますが、起動していない場合は、事前に [systemctl start snapd.socket] で起動しておく必要があります。 |
root@dlp:~# snap install microk8s --classic microk8s (1.20/stable) v1.20.6 from Canonical✓ installed |
[2] | MicroK8s インストール後は、自動的に起動しています。停止や起動等は以下のように実行します。 |
