ubuntu22.04在线安装docker和nvidia-container-toolkit

一、安装docker

1. 安装必要依赖

bash 复制代码

sudo apt-get update
sudo apt-get install -y ca-certificates curl gnupg lsb-release

2. 添加阿里云的 Docker GPG 密钥

bash 复制代码

# 创建存放密钥的目录
sudo install -m 0755 -d /etc/apt/keyrings
# 下载并转换密钥
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
# 设置密钥文件权限
sudo chmod a+r /etc/apt/keyrings/docker.gpg

3. 添加阿里云的 Docker 软件源

bash 复制代码

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

4. 安装 Docker 核心组件

bash 复制代码

sudo apt-get update
sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin

5.验证 Docker

bash 复制代码

docker --version

二、安装nvidia-container-toolkit

1.添加GPG 密钥

bash 复制代码

curl -fsSL https://mirrors.ustc.edu.cn/libnvidia-container/gpgkey | sudo gpg --dearmor -o /usr/share/keyrings/nvidia-container-toolkit-keyring.gpg

2.配置apt国内镜像库

bash 复制代码

curl -s -L https://mirrors.ustc.edu.cn/libnvidia-container/stable/deb/nvidia-container-toolkit.list | \
sed 's#deb https://nvidia.github.io#deb [signed-by=/usr/share/keyrings/nvidia-container-toolkit-keyring.gpg] https://mirrors.ustc.edu.cn#g' | \
sudo tee /etc/apt/sources.list.d/nvidia-container-toolkit.list

3.安装nvidia-container-toolkit

bash 复制代码

sudo apt update && sudo apt install nvidia-container-toolkit

4. 配置 Docker Runtime

bash 复制代码

sudo nvidia-ctk runtime configure --runtime=docker

5. 重启 Docker

bash 复制代码

sudo systemctl restart docker

6. 测试 GPU Docker

bash 复制代码

docker run --rm --gpus all \
nvidia/cuda:13.0.0-base-ubuntu22.04 \
nvidia-smi

三、配置 Docker Hub 镜像源（国外源访问不了或者很慢）

bash 复制代码

sudo mkdir -p /etc/docker
sudo nano /etc/docker/daemon.json

写入：

bash 复制代码

{
  "registry-mirrors": [
    "https://docker.1ms.run",
    "https://dockerproxy.com",
    "https://hub.rat.dev"
  ]
}

重启

bash 复制代码

sudo systemctl daemon-reload
sudo systemctl restart docker
