How to install docker in win7

Before going to discuss how to install Docker in win7, let’s briefly introduce Docker. Docker is an open source application container engine that allows developers to package their applications and their dependencies into a complete container, which can be easily deployed and run in any environment that supports Docker. Docker containers are similar to virtual machines, but they are more lightweight, easier to migrate and deploy, and easier to manage. As a result, Docker has become standard for modern application development and deployment.

Although Docker has gradually become the standard for modern development, it is not easy to install Docker on some old operating systems, such as Windows 7. The kernel of the Widows7 operating system does not support the operation of Docker. Therefore, if you want to run Docker containers on Windows7, you must use third-party tools.

Let’s discuss how to install Docker on the Win7 operating system.

Step 1: Download and install Docker Toolbox
Docker Toolbox is an old but reliable solution for running Docker containers on Windows 7. First, you need to go to the Docker official website, find the appropriate version of Docker Toolbox and download it.

Step 2: Run Docker Quickstart Terminal
After the installation is complete, double-click on the desktop to run Docker Quickstart Terminal. This tool automatically configures VirtualBox to install Docker on Windows. Please note that on first run it may error. This is due to incompatibility issues that may arise during the configuration of VirtualBox. If this happens, please restart your computer and try again.

Step 3: Test the Docker container
After completing the above steps, you can test whether the Docker container is successfully installed by running the command docker version. If the installation is successful, you should see an output similar to the following:

Client:
Version: 17.05.0-ce
API version: 1.29
Go version: go1.7.5
Git commit: 89658be
Built: Thu May 4 22:10:54 2017
OS/Arch: windows/amd64

Server:
Version: 17.05.0-ce
API version: 1.29 (minimum version 1.12)
Go version: go1.7.5
Git commit: 89658be
Built: Thu May 4 22:10:54 2017
OS/Arch: linux/amd64
Experimental: false

Step 4: Run the container
If the above tests pass, then you can happily run the Docker container on Win7. A simple example: you can run the docker run -it ubuntu /bin/bash command to start an Ubuntu container. If all goes well, you will see a command line prompt indicating that you are running an Ubuntu container.

Summary
Installing Docker on Windows 7 may be a bit troublesome, but through the tool Docker Toolbox, we can still happily run Docker containers on the old operating system. Finally, it should be noted that Win7 has become a thing of the past, and Microsoft has stopped supporting it. If conditions permit, it is recommended to upgrade to Windows 10 to better support the latest technology.
