Docker Configuration Domestic Mirror Source Does Not Work

  docker, question

refer toDocker China Official Mirror Speeds UpIt is equipped with a domestic mirror image source, but it has not been effective all the time. Using docker pull, you still visit foreign warehouses.

Not even direct pull:

Why didn’t I use my mirror source? How to solve it?

This image has never been used. It is recommended to directly use the docker image on Aliyun’s cloud service.https://www.aliyun.com/produc …(Free, can also be used locally after opening), or at HKUST:https://mirrors.ustc.edu.cn/h …
