How to Use the Docker Import Command

The docker import command is used to import a previously exported Docker image as a new image. It allows you to create a new image from a tar archive that contains the exported contents of a container’s filesystem.

To use the docker import command, you can follow these steps:

Make sure you have Docker installed and running on your system.

Open a terminal or command prompt.

To import a Docker image, you need to have a tar archive that contains the exported contents of a container’s filesystem. If you don’t have an exported image, you can create one using the docker export command.

Once you have the tar archive, you can use the docker import command followed by the path to the tar archive and the desired name for the new image:

    docker import {{tar-archive-path}} {{new-image-name}}

    
    
         

Replace {{tar-archive-path}} with the actual path to the tar archive file, and {{new-image-name}} with the desired name for the new image.

After running the docker import command, Docker will import the contents of the tar archive and create a new image with the specified name.

You can verify that the new image has been created by using the docker images command:

    docker images

    
    
         

This will display a list of available images, including the newly imported image.

Please note that the docker import command imports the contents of a container’s filesystem as a new image, but it does not include metadata such as the image’s history or environment variables. To import an image along with its metadata, you can use the docker load command.
