安装 Docker（Ubuntu/Debian）

1. 卸载旧版本

for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do apt-get remove $pkg; done

旧版本的镜像、容器、卷和网络保存在 /var/lib/docker，不会自动删除，如需清理请手动删除该目录。

2. 添加官方软件源

apt-get update
apt-get install ca-certificates curl gnupg

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

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

3. 安装 Docker

apt-get update
apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
docker -v

安装 Docker Compose（独立版）

按需修改版本号 v2.xx.x：

curl -L https://github.com/docker/compose/releases/download/v2.24.1/docker-compose-$(uname -s)-$(uname -m) \
  -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
docker-compose -v
