Solution to the problem of slow docker pull image speed

Currently, Docker has an official mirror for China. For details, please visit https://www.docker-cn.com/registry-mirror

When in use, Docker China's official image acceleration can be accessed through registry.docker-cn.com. This image library only contains popular public images. Private images still need to be pulled from the US image library.

You can use the following command to pull directly from the image acceleration address:

$ docker pull registry.docker-cn.com/myname/myrepo:mytag

For example:

$ docker pull registry.docker-cn.com/library/ubuntu:16.04

Note: Unless you have modified the `--registry-mirror` parameter to the Docker daemon (see below), you will need to specify the full name of the official image. For example, library/ubuntu, library/redis, library/nginx.

Configure the Docker daemon with --registry-mirror

You can configure the Docker daemon to use the Docker official image acceleration by default. This way you can accelerate image pulling through official images by default without having to specify registry.docker-cn.com every time you pull.

You can pass the --registry-mirror parameter when starting the Docker daemon:

$ docker --registry-mirror=https://registry.docker-cn.com daemon

To make the changes permanent, you can modify the /etc/docker/daemon.json file and add the registry-mirrors key.

{
 "registry-mirrors": ["https://registry.docker-cn.com"]
}

After saving the changes, restart Docker for the configuration to take effect.

service docker restart

Note: You can also set this up using Docker for Mac and Docker for Windows.
