What Is The Difference Between Import And Load In Docker?

Docker is a container orchestration platform that is used for containerizing applications. The service offers both free and premium tiers. The software that hosts the containers is known as Docker Engine. Docker import is a Docker command that creates a Docker image by importing material. Docker load loads an image from a tar archive as STDIN, containing images and tags

Difference Between Import And Load In Docker

Docker import	Docker load
Docker import is a Docker command that creates a Docker image by importing material from an archive or tarball generated after exporting a container.	Docker load loads an image from a tar archive as STDIN, containing images and tags.
Import command is used with tars made using Docker export, it dumps the container to a file and flattens the image by deleting the container’s history.	Load command is used with tar files generated using Docker save.
Docker import also generates a tarball, but without any layer/history.	Docker load will create a tarball including all parent layers, tags, and versions.
Syntax of Docker import is $ docker import [options] file|URL|- [REPOSITORY[:TAG]]	Syntax of Docker load is docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE

Docker Import

Docker import is a Docker command that creates a Docker image by importing material from an archive or tarball generated after exporting a Docker container. An imported container is imported as a Docker image and functions using the file system of the exported container.

Syntax

$ docker import [options] file|URL|- [REPOSITORY[:TAG]]

Step By Step Guidelines To Import Docker Image

Step 1: Using the Dockerfile below, first make a Docker image.

$ docker build -t my-image:v2 .docker 

Step 2: Use the following command to run the container with that image.

$ docker run my-image:v2.21

• Check the container status of the above created one with the following command:

 $ docker ps –a

Step 3: Use the following command to export the container to a tar file called helloworld.tar

$ docker export <container_ID> > <file_name>

( or )

$ docker export <container_name> > <file_name>

• The following practical screenshot illustrates the archiving the container file.
  

Docker Load

Docker load loads an image from a tar archive as STDIN, containing images and tags. Docker loads saves an image to a tar archive stream to STDOUT, including all parent layers, tags, and versions .

Syntax

$ docker load [OPTIONS] < <Archived files>

Step By Step Guidelines To Load Docker Image

Step 1: Checking the Images list with the following docker command:

$ docker image ls

Step 2:To export a container’s filesystem as a tar archive, use the docker export command.To generate a filesystem image, use the docker import command to import the contents of a tarball.Loading Docker image from the Archived file to create busybox.tar.gz.

 $ docker load < busybox.tar.gz

Step 3: Load an repository from a tar archive .It restores both the photos and the tags.Save one or more images to a tar archive using the docker save command (streamed to STDOUT by default).When it is finished, we can use CMD to see that the file has been loaded as a Docker image:

 $ docker load --input fatra.tar

Conclusion

In Conclusion, Docker import is a Docker command that creates a Docker image by importing material from an archive or tarball generated after exporting a container.Docker load loads an image from a tar archive as STDIN, containing images and tags.
