The Docker server is abroad, so it will be very slow to install docker using docker.io, and sometimes it will not be installed successfully due to the timeout. Therefore, I am using the domestic image acceleration of the Network and Educational Technology Center of Northwest University of Agriculture and Forestry Science and Technology, and there are many image acceleration sites in China, such as Aliyun, Tencent Cloud, NetEase, Tsinghua University and so on.
