Kubernetes : Minikube : インストール2018/10/22 |
|
Docker コンテナ オーケストレーションシステム Kubernetes のインストールと設定です。
当例では、Minikube をインストールして、シングルノード上の仮想マシン内で Kubernetes クラスターを構成します。
|
| [1] | 仮想マシンを利用するため、Minikube でサポートするハイパーバイザーをインストールしておきます。 当例では KVM をインストールして進めます。 その他、VirtualBox, VMware Fusion, HyperKit が利用可能です。 |
|
root@dlp:~# apt -y install qemu-kvm libvirt-bin virtinst bridge-utils
|
| [2] | Kubernetes リポジトリを設定して必要なツールをインストールし、Minikube を起動します。 |
