sudo apt update
sudo apt install apt-transport-https ca-certificates curl gnupg-agent software-properties-common

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io

sudo systemctl status docker

sudo usermod -aG docker $USER
sudo chmod 777 /var/run/docker.sock

## Install the NVIDIA-container package to enable GPU in docker
You can check the page from [here](https://nvidia.github.io/nvidia-docker/).

For Debian-based distributions:

curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | \
  sudo apt-key add -
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | \
  sudo tee /etc/apt/sources.list.d/nvidia-docker.list
sudo apt-get update

Install `nvidia-container-toolkit`:

sudo apt-get update && sudo apt-get install -y nvidia-container-toolkit 
sudo systemctl restart docker

Please dont forget to restart docker!

Also, need to install

sudo apt-get install -y nvidia-container-runtime

## Daemon.json file

$ cat /etc/docker/daemon.json

{
    "runtimes": {
        "nvidia": {
            "path": "nvidia-container-runtime",
            "runtimeArgs": []
         }
    },
    "graph": "/home/user/472GB/Docker",
    "storage-driver": "overlay2",
    "insecure-registries":["ip:5568"]
}

**Important**

測試如果是 `19.03`版本儲存的位置key是`graph`
但是測試 `23.0.06`版本儲存的位置key改為 `data-root`

{
    "data-root": "/home/chieh/472GB/Docker"
}

# Install docker-compose

Reference: [compose-install](https://docs.docker.com/compose/install/)

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

# Release Docker Space

檢查未使用的 Docker 資源：
使用以下指令列出未使用的容器、網路和暫存卷：

docker system prune

這個指令會提示你是否要刪除這些未使用的資源，確認後即可清理。

清除 Docker 快取資源：
Docker 會快取下載的映像檔和建構過程的中間檔案，這些資源可能佔用著磁碟空間。你可以使用以下指令清除這些快取資源：

docker builder prune
