1. Image acceleration

By default, Docker downloads images from the official image address Docker Hub. Because the server is abroad, the download speed is often very slow. In order to improve the download speed of the image, we can manually configure the domestic image accelerator to make the download speed go fast.

There are many options for domestic mirror accelerators, such as Aliyun, DaoCloud and so on.

This article mainly talks about how to configure Aliyun's mirror accelerator.

2.1 Log in to Ali Cloud to get acceleration information

First of all, you need to sign up for an Aliyun account. If not, jump to register via the following link: dev.aliyun.com/

Jump to image acceleration page cr.console.aliyun.com/, to get acceleration configuration information:
