一、配置阿里云docker apt源

Ubuntu 放弃了apt-key的GPG 密钥的管理方法，用户可以直接添加gpg密钥到/etc/apt/trusted.gpg.d/目录下。
同时添加删除apt source 直接在/etc/apt/sources.list.d/目录下操作即可。

1、删除旧的镜像源

#旧版操作方法
apt-key list # 列出许可证，在/trusted.gpg.d/中的是列不出来的
sudo apt-key del 0EBFCD88 # 根据编号删除gpg密钥
sudo rm /etc/apt/sources.list.d/docker.list #删除之前的源
sudo apt-get update # 更新apt 目录index#新版方法
ls /etc/apt/trusted.gpg.d/
sudo rm /etc/apt/trusted.gpg.d/docker-archive-keyring.gpg
sudo rm /etc/apt/sources.list.d/docker.list
sudo apt-get update

2、添加阿里云docker apt源

curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/docker-archive-keyring.gpg
echo "deb [arch=amd64 signed-by=/etc/apt/trusted.gpg.d/docker-archive-keyring.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null#将 GPG 密钥存储在 /usr/share/keyrings/ 目录下，而不是 /etc/apt/trusted.gpg.d/ 目录下，这是因为新的推荐方法是使用 signed-by 选项将特定的密钥与特定的存储库关联起来。这种方法比将所有密钥存储在 /etc/apt/trusted.gpg.d/ 目录下更安全，因为它减少了一个密钥对多个存储库的信任范围。
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
