普段はDocker DaemonとしてOrbStackを使用しているが、Apple SiliconのMac上でx86_64との互換性の問題が起きやすいので、
互換性の問題が起きた時の代替としてVM(QEMU)でx86_64用Docker Daemonを起動する。


limaをインストール。

```
brew install lima
```

Docker用のtemplateを使ってlimaをVMを起動。

```
limactl start --name=build --arch=x86_64 --tty=false --mount-writable template://docker
```

Mac上でDockerのcontextを設定。

```
docker context create lima-build --docker "host=unix:///Users/tmaki/.lima/build/sock/docker.sock"
docker context use lima-build
```

Mac上でDocker contextを確認。

```
$ docker context ls
NAME           DESCRIPTION                               DOCKER ENDPOINT                                    ERROR
default        Current DOCKER_HOST based configuration   unix:///var/run/docker.sock                        
lima-build *                                             unix:///Users/tmaki/.lima/build/sock/docker.sock   
orbstack       OrbStack                                  unix:///Users/tmaki/.orbstack/run/docker.sock  
```

Mac上で`docker run`を実行。

```
docker run --rm hello-world
```

VMにログイン。

```
limactl shell build 
```

VM上でDocker contextを確認。

```
$ docker context list
NAME         DESCRIPTION                               DOCKER ENDPOINT                    ERROR
default      Current DOCKER_HOST based configuration   unix:///var/run/docker.sock        
rootless *   Rootless mode                             unix:///run/user/503/docker.sock 
```

おまけ1。`kubectl`のインストールメモ。

```
sudo apt-get update
sudo apt-get install -y apt-transport-https ca-certificates curl
curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.30/deb/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/kubernetes-apt-keyring.gpg
sudo chmod 644 /etc/apt/keyrings/kubernetes-apt-keyring.gpg
echo 'deb [signed-by=/etc/apt/keyrings/kubernetes-apt-keyring.gpg] https://pkgs.k8s.io/core:/stable:/v1.30/deb/ /' | sudo tee /etc/apt/sources.list.d/kubernetes.list
sudo chmod 644 /etc/apt/sources.list.d/kubernetes.list
sudo apt-get update
sudo apt-get install -y kubectl 
```

おまけ2。`tanzu`のインストールメモ。

```
curl -fsSL https://packages.vmware.com/tools/keys/VMWARE-PACKAGING-GPG-RSA-KEY.pub | sudo gpg --dearmor -o /etc/apt/keyrings/tanzu-archive-keyring.gpg
echo "deb [signed-by=/etc/apt/keyrings/tanzu-archive-keyring.gpg] https://storage.googleapis.com/tanzu-cli-os-packages/apt tanzu-cli-jessie main" | sudo tee /etc/apt/sources.list.d/tanzu.list
sudo apt update
sudo apt install -y tanzu-cli
```
