How to use domestic image warehouse for Docker

1. Problem description

Due to some reasons, the download speed of Docker images in China is particularly slow. So for immersive development. It is best to switch to a domestic source. Here we take the 163 mirror repository as an example. First modify the /etc/docker/daemon.json configuration file.

sudo vi /etc/docker/daemon.json

Replace the content of this file with Alibaba source. The modified /etc/docker/daemon.json file is:

{
  "registry-mirrors": ["http://hub-mirror.c.163.com"]
}

Then systemctl restart docker restart Docker command. Then use the docker info command to view the image warehouse information. The results are as follows:

2. Summary

Most of the code in the book is correct if you run it directly, but there are always some software updates that the author cannot do anything about. It is common that the previous API was correct, but it was later abandoned or modified. So we need to track the source code. This is just a small question. Without the selfless dedication of our predecessors, it is hard to imagine how much we can learn in a day. Thank you to all the seniors for their hard work, which helped us avoid many detours!
