How to change the image in win10docker

Win10Docker is an open source container technology for the Windows 10 operating system. It allows users to quickly build and use Docker containers in the Windows environment. Changing the Docker image is a step that is often required when using Win10 Docker. Next, I will introduce to you how to change the image of Win10 Docker.

First of all, we need to understand the concept of Docker image. The Docker image is the basis of the container. It contains the file system and applications necessary for the container to run, as well as other dependencies. Common Docker images, such as Ubuntu, CentOS, Nginx, etc., can be found on Docker Hub. When we need to run a new container, we need to download the required image file from Docker Hub, and the download speed is often limited by network conditions.

In order to solve this problem, we can change the Docker image and replace the foreign image on Docker Hub with a domestic image. The specific steps are as follows:

Step 1: Open Win10Docker

If you have not installed Win10Docker, you can download and install it from the official website. After the installation is complete, open the Win10 Docker application.

Step 2: Enter the settings page

In the Win10Docker main interface, click the "Settings" button in the menu bar to enter the settings page.

Step 3: Change the Docker configuration file

In the settings page, find the "Docker Engine" submenu and click the "Advanced" button to open the Docker configuration file. In this file, find the following content:

{
  "registry-mirrors": []
}

Add the mirror address you want to use in square brackets, such as Alibaba Cloud Mirror:

{
  "registry-mirrors": ["https://3kidwo9m.mirror.aliyuncs.com"]
}

Note: If there are multiple mirror addresses, add them Separate with commas.

Step 4: Save and restart

After completing the above operations, save the changes and wait for the Docker engine to restart. This process may take some time, just be patient.

If you need to verify whether the Docker image is successfully changed, you can enter the following command in the terminal:

docker info

Check whether the registry-mirrors in the output result correctly displays the changed address.

Here, we have introduced how to change the image of Win10Docker. By changing the Docker image, users can use Docker containers more smoothly in the Windows environment. It should be noted that domestic mirror addresses may not be suitable for all applications and dependent libraries, and you need to consider carefully before changing them.
