如何在 Ubuntu 上安装国内源的 Docker

# 更新软件包索引
sudo apt-get update
# 安装需要的软件包以使apt能够通过HTTPS使用仓库
sudo apt-get install ca-certificates curl gnupg lsb-release

# 添加Docker官方的GPG密钥
curl -fsSL https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
# 设置稳定版仓库
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

# 添加阿里云官方GPG密钥
curl -fsSL http://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
# 写入阿里云Docker仓库地址
sudo sh -c 'echo "deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" > /etc/apt/sources.list.d/docker.list'

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

sudo systemctl status docker
docker --version

{
    "registry-mirrors": [
        "https://cr.console.aliyun.com",
        "https://ccr.ccs.tencentyun.com",
        "https://github.com/ustclug/mirrorrequest"
    ]
}

sudo systemctl daemon-reload
sudo systemctl restart docker

sudo docker info 

sudo groupadd docker

sudo gpasswd -a ${USER} docker
