Docker Save in Windows - Shell/Bash

Docker is a powerful tool for building, shipping, and running applications in containers. One of the key features of Docker is the ability to save and load images from a registry or from a local file system. In this tutorial, we will explore how to use the docker save command in Windows using the Shell/Bash.

Prerequisites

• Docker must be installed on your Windows machine.
• You should have basic knowledge of using the command line interface in Windows.

Saving Docker Images in Windows

To save a Docker image in Windows, follow these steps:

1. Open a Shell or Bash terminal on your Windows machine.
2. Check the list of available images by running the following command:

   docker images
   

3. Identify the image that you want to save and note the image name and tag.
4. Run the following command in the terminal to save the image:

   docker save <image-name>:<tag> -o <path-to-output-file>
   

   For example:

   docker save my-image:latest -o /path/to/my-image.tar
   

   This will save the my-image image with the latest tag to the file /path/to/my-image.tar.
5. Once the image is saved, you can verify its existence by checking the output file:

   ls /path/to/
   

   You should see the my-image.tar file listed.

Loading Docker Images in Windows

To load a Docker image from a saved file, follow these steps:

1. Open a Shell or Bash terminal on your Windows machine.
2. Run the following command to load the image:

   docker load -i <path-to-input-file>
   

   For example:

   docker load -i /path/to/my-image.tar
   

   This will load the my-image image with the latest tag from the file /path/to/my-image.tar.
3. Once the image is loaded, you can verify its existence by checking the list of available images:

   docker images
   

   You should see the my-image image with the latest tag listed.
