How to use docker on windows

With the development of cloud computing and containerization technology, Docker has become one of the most popular container solutions. It packages applications in easily portable containers and provides the ability to quickly deploy and run applications. Installing and configuring Docker on Windows operating systems is becoming easier and easier. This article will explain how to install and configure Docker on Windows, and how to use it to run and manage containers.

Installing Docker

Before installing Docker, you need to ensure that your Windows operating system is a 64-bit version and supports Hyper-V virtualization technology. If your system does not support Hyper-V, you cannot install Docker.

Before installing Docker, you need to uninstall any previously installed versions. Then, go to the download page of the Docker official website, download Docker Desktop for Windows and install it.

After the installation is complete, find the Docker icon on the desktop and double-click it to open it. You will see the Docker Daemon running. Now you have successfully installed Docker.

Configuring Docker

In the default configuration, Docker uses Linux containers on Windows. If you want to run Windows containers on Windows, change the container type to Windows containers in Docker settings.

To change the container type, click the Docker icon, select Settings > Docker Engine tab, and add the following:

{
    "exec-opts": ["isolation=hyperv"],
    "experimental": true,
    "windows": true
}

Next, you need to restart Docker , to read the new configuration. Now you have successfully configured Docker to run Windows containers on Windows.

Run and manage containers

Docker provides many commands and options to help you run and manage containers. The following are some commonly used commands:

• docker run: Run a command in a new container using the specified image.
• docker ps: List all currently running containers.
• docker stop : Stop a running container.
• docker rm : Delete a stopped container.
• docker images: List all images on the current system.
• docker pull : Get the image from the Docker image warehouse.

When using these commands, please pay attention to filling in the correct container ID and image name.

When running a container, you can specify its name to facilitate management. For example, the following command will run a container named "web" using the nginx image.

docker run --name web nginx

If you want to view the container log, you can use the following command:

docker logs 

If you want to enter a running container and execute a command, you can use the following command:

docker exec -it  bash

This will open a default bash shell inside the container where you can execute all commands.

Summary

Docker is a popular container solution that allows you to easily package and run applications and provides fast application deployment and management. Installing and configuring Docker on Windows is also getting easier. Through the introduction of this article, you have learned how to install and configure Docker on Windows, and use it to run and manage containers.
