what is docker load

Docker is an open-source platform that allows developers to automate the deployment of applications inside containers. These containers are portable and lightweight, allowing developers to run applications anywhere, anytime, on any platform. Docker load is a command in the Docker platform that is used to load images into Docker. It is an essential command, and every Docker user should have a good understanding of how it works and how it can be used.

What is Docker Load?

Docker Load is a command in the Docker platform used to load Docker images. It is used to transfer an image from one machine to another. The command is mainly used when there is no registry available, and images need to be saved and loaded manually. The images can be loaded into Docker in two ways:
1. From a saved tar file
2. From a Docker Image Stream

How to Load Docker Images

Loading Docker images using the Docker Load command is a simple process that consists of a few steps, as outlined below:
1. Save the Docker image. This can be done using the Docker save command.
2. Transfer the saved image to the desired machine.
3. Load the transferred image onto the desired machine using the Docker load command.
The first step to loading a Docker image is saving it. This step is only necessary if the image is not already saved. The command used to save an image is “docker save -o .tar”. This command saves the Docker image to a tar file. Once the image has been saved, it can be transferred to the desired machine using any file transfer protocol. Once the image has been transferred to the desired machine, it can be loaded into Docker using the “docker load -i .tar” command.

Docker Load Examples

Let’s look at some examples of how the Docker Load command can be used:
Example 1: Loading a Docker image from a tar file.
If we have a tar file called myapp.tar that contains a Docker image, we can load the image onto Docker using the following command:
docker load -i myapp.tar Example 2: Loading a Docker image stream.
If we want to load a Docker Image Stream, we can use the following command:
docker load < myapp.tar In both examples, the Docker Load command is used to load the Docker Image onto the system.

Conclusion

In conclusion, Docker load is an essential command in the Docker platform that is used to load Docker images onto a system. Whether we are transferring images from one machine to another or trying to save images without the use of a registry, Docker Load is essential for the process. The command is easy to use and offers developers a simple way of transferring and loading Docker images in a fast and efficient manner. As more developers continue to use the Docker platform, it is essential to understand the various commands and their functions in the platform.
