How to pull a Docker image

1. Log in to Docker Hub:
   If you are not logged into Docker Hub, execute the following command: docker login . Enter your Docker ID and password.

2. Pull the mirror:
   To pull the image, use the following command:

    <code>docker pull [镜像名称]</code>

   For example, to pull an Nginx image, execute: docker pull nginx .

3. Specify the mirror version:
   By default, Docker pulls the latest version of the image. You can pull a specific version by specifying a tag, for example: docker pull nginx:1.21 .
4. Check the mirror:
   To view the pulled images, execute the following command: docker images .

Other options:

• Specify the mirror repository:
  You can pull private images by specifying the image repository, for example: docker pull my-registry.example.com/my-image .
• Use alias:
  You can use alias to simplify pull commands, for example: docker pull nginx:latest can be replaced with docker pull nginx .
