对于无图形界面的 Ubuntu Server，直接安装Dokcer Engine就可以。

1. 安装依赖

sudo apt update
sudo apt install ca-certificates curl gnupg

2. 配置 docker 的 GPG 密钥

sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

3. 添加 Docker 的 apt 仓库

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

4. 安装 Docker Engine

sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
# 验证
docker version
docker compose version
# Hello World
sudo docker run hello-world

5. 配置国内镜像

vi /etc/docker/daemon.json

{
  "registry-mirrors": ["http://hub-mirror.c.163.com","https://registry.docker-cn.com","https://docker.mirrors.ustc.edu.cn"]
}

sudo service docker restart
