首先安装依赖

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

然后再信任Docker的公钥

install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

再添加仓库

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

最后安装

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