How to install docker image file

Docker is a software platform for containerized applications that allows users to deploy applications in a fast, repeatable and secure manner. After installing Docker, you can build a basic environment for your project by installing the image file. In this article, we will introduce how to install a Docker image file.

Step1: Obtain Docker images for your project

Docker provides a central image warehouse called Docker Hub so that users can easily obtain commonly used containers. When accessing Docker Hub, you need to register for an account.

You can search for the image you want to use by using Docker Hub's graphical user interface. Just enter the name of the desired image and press Enter to view the available versions and other information about the image.

Alternatively, you can use the Docker command line interface (CLI) to search and install the image. In the command line interface, you can search for any web repository that has a docker image using the following command:

docker search

This will search Docker Hub for the repository with the provided All images of the name. You can use the following command to pull (i.e. download) the required image:

docker pull

This command will download a specific image from Docker Hub and add it to Stored in the Docker registry on your local machine.

Step2: Run the image in Docker

After installing the image, you can use the following command to run it in a Docker container:

docker run

This will start the required image in the new container. Once completed, you can use the following command to view the Docker image id:

docker ps

To view the processes running in the container, use the following command:

docker logs

Step3: Manage Docker containers

Users can use Docker CLI to manage running Docker containers. The following are some common container management commands:

• Stop the container: docker stop
• Start the container: docker start
• Delete container: docker rm
• View container: docker ps
• Enter container: docker attach

Summary

In this article, we introduced how to install the Docker image file and run the container. In short, Docker provides a fast, repeatable, and secure way to deploy applications. Using Docker, users can quickly deploy their applications and manage their development and production environments.
