WSL2:AlmaLinux 8.5にdockerを用意した時の記録
dockerって何？美味いの？((((；ﾟДﾟ))))ｶﾞｸｶﾞｸﾌﾞﾙﾌﾞﾙ
日進月歩ですな、コンテナの知識や理解がないと若者ら失笑されそうなんでとりあえず触っておこっと。
手順
WSL2:AlmaLinux起動
リポジトリ追加
- デフォでは、そのままdnfっても駄目だそうで、dockerのリポジトリが必要
$ sudo dnf config-manager \
add-repo> --add-repo \
> https://download.docker.com/linux/centos/docker-ce.repo
Adding repo from: https://download.docker.com/linux/centos/docker-ce.repo
Dockerのインストール
- 以下３つのパッケージをインスコ
- docker-ce:デーモン本体
- docker-ce-cli:操作するためのコマンド達
- containerd.io:ランタイム（プログラムとかを動かす時に必要な部品）
$ sudo dnf -y install docker-ce docker-ce-cli containerd.io

- おや？エラーですな？docker daemonが起動していないようだ。
- いろいろググって調べた結果、WSL2でdocker使うには、Windows OS側で、Docker desktopをインストールしなさいということが判明
Docker desktopのインストール
- Docker公式にアクセス
- ダウンロードページからDocker Desktop for Windowsをゲット
- Docker Desktop Installer.exeをインストール
- Docker Desktop起動し、Settingsへ、
-
Generalにて、Use the WSL2 Base engineにチェックが付いてることを確認
-
-
Resources-WSL INTEGRATION にて、以下を確認
- Enable integation with my default WSL distroにチェックが付いてる
- AlmaLinux-8が有効になっている
-
Apply & Restartボタンをクリック
-
