docker-ce安装

docker-ce是linux装机必备。

自动安装

curl -fsSL https://get.docker.com -o get-docker.sh
sh ./get-docker.sh

手动安装

如果过去安装过 docker，先删掉：
for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do sudo apt remove $pkg; done

首先安装依赖：
apt-get update
sudo apt install ca-certificates curl gnupg
信任 Docker 的 GPG 公钥并添加仓库：

install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/debian \
  "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

最后安装
sudo update
sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
