Docker for Mac から Lima に切り替える
Docker for Mac から他のツールに切り替えないといけなくなった際に、ドヤ顔出来るようにシュミレーションを行った時のログです。
Lima とは？
Windows 上で Linux を動作させる WSL があるように、MacOS 上でも Linux を動作させる MacOS 版 WSL として開発されたのが Lima です(雑)。
Lima と Docker をインストールする
Docker がインストール済みの場合は、Lima のみをインストールする。
$ brew install lima docker
Lima の設定ファイルを設置する
公式が配布している設定ファイルを参考にlima-hoge.ymlを設置します。

limactl shell lima-hogeでVMにログイン出来るが、export LIMA_INSTANCE=lima-hogeをすれば、limaでログインやコマンドを実行出来る。
$ limactl shell lima-hoge
xxxxx@lima-lima-hoge:/Users/xxxxx/projects/hoge$ exit
logout
$
$ export LIMA_INSTANCE=lima-hoge
$ lima
xxxxx@lima-lima-hoge:/Users/xxxxx/projects/hoge$ exit
logout
$
$ lima docker compose version
Docker Compose version v2.0.0-rc.3
Docker Compose V2 を利用する
Docker Compose V2 は、まだデフォルトでは有効になっていない為、V2を利用出来るようにする。
$ export LIMA_INSTANCE=lima-hoge
$ lima
xxxxx@lima-lima-hoge:/Users/xxxxx/projects/hoge$ mkdir -p ~/.docker/cli-plugins/
xxxxx@lima-lima-hoge:/Users/xxxxx/projects/hoge$ curl -SL https://github.com/docker/compose/releases/download/v2.0.0-rc.3/docker-compose-linux-amd64 -o ~/.docker/cli-plugins/docker-compose
xxxxx@lima-lima-hoge:/Users/xxxxx/projects/hoge$ chmod +x ~/.docker/cli-plugins/docker-compose
xxxxx@lima-lima-hoge:/Users/xxxxx/projects/hoge$ exit
普段と同じようにビルドする
$ lima docker compose build
$ lima docker compose up -d
VMを停止、削除する
