MacBook に Docker をインストールした際の備忘録
comapiDocker CLI のインストール
brew install docker
- Docker CLI のインストールのみ
- Docker daemon のインストールはないためこの段階ではまだ Docker を使用はできない
comapiダウンロード時のログを以下に残しておく。

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(arm64v8)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

Docker コマンドのタブ補完ができるようになるまで
以下「Git コマンドのタブ補完ができるようになるまで」を行うと Docker コマンドもタブ補完できるようになる。
comapidocker compose を使えるようになるまで
brew install docker-compose
mkdir -p ~/.docker/cli-plugins
ln -sfn /usr/local/opt/docker-compose/bin/docker-compose ~/.docker/cli-plugins/docker-compose
% docker compose --version
Docker version 28.0.1, build 068a01ea94
よく見ると Docker のバージョンを出力しているだけでまだ docker compose は使えなかった。
comapi/usr/local 下に何もいない。
comapi以下で brew でインストールした docker-compose のパスを確認すると
brew --prefix docker-compose
以下に配置されていることが分かった。
/opt/homebrew/opt/docker-compose
というわけでシンボリックリンクを以下に変更。
ln -s $(brew --prefix docker-compose)/bin/docker-compose ~/.docker/cli-plugins/docker-compose
docker compose コマンドが使えるようになった。
% docker compose version
Docker Compose version 2.34.0
※ docker compose のバージョン確認のコマンドには -- は付けないのね。
comapiコンテナ内からマウントしたホストに書込みができない問題

comapiVSCode の Dev Containers で Docker が認識されていない問題
% docker context ls
NAME DESCRIPTION DOCKER ENDPOINT ERROR
default * Current DOCKER_HOST based configuration unix:///Users/{user name}/.lima/default/sock/docker.sock
Warning: DOCKER_HOST environment variable overrides the active context. To use a context, either set the global --context flag, or unset DOCKER_HOST environment variable.
VSCode の setting.json に以下追記。(user name は適宜書き換え)
{
"docker.host": "unix:///Users/{user name}/.lima/default/sock/docker.sock"
}
メモリの制限を変更
limactl stop default
limactl edit default
# memory: "8Gib" を追記
limactl start default
