Docker is a container platform that allows you to build, test and deploy applications quickly. A developer defines all the dependencies in a "docker file" which is used to build a Docker image that defines a docker container. Doing this ensures that your application will run in any environment. The Docker toolbox is a kind of older version of the Docker desktop.
Why Docker?
Docker is open source containerization platform tool that allows devlopers to package an application with all its dependencies including libraries, softwares, application code, configuration as single entity. It manages the life cycle of the containers such as container creation, container execution, container termination etc..
Docker toolbox is a software tool that is used in older windows and macOS computer which doesn't support directly using docker. Docker toolbox bundles Docker and all the related tools into one package making it easier to setup Docker on these systems. It uses a small virtual machine to run docker containers letting users to work with containers even if their operating system doesn't support it directly. While Docker desktop can be used in the newer systems, still toolbox is handy for older computers that need Docker features.
The following are major features comparisons between Docker Desktop and Docker Toolbox.
Features | Docker Desktop | Docker Toolbox |
|---|
Operating Systems | It is supported in Windows 10 Pro and In Enterprise Edtions | It is supported in older Windows(7,8,10) |
|---|
Requirements | It requires Hyper-V for Windows or Apple's Hypervisor | No Hypervisor-V required for windows |
|---|
Integration | It provides seamless integraiton with host OS | Its integration depends on Virtual Machine for operations |
|---|
Resource Usuage | It utilizes more system resources due to tighter integration with the host OS | It uses a light weight virtual machine, due to this it consumes lesser resources. |
|---|
Features | It offers additional features like Kubernetes | It provides limited features on compared to Docker Desktop. |

Before installing Docker Toolbox on your Windows system, Make sure that your system meets the following minimum requirements:
- 64-bit Windows 7 (or higher)
- Virtualization enabled
Check System Configuration
The initial step involves checking whether your system configuration aligns with the necessary prerequisites for the successful installation of Docker Toolbox.
1. Check Windows Version
- Check your windows version by folowing below steps:
- Click on Windows start and enter the "Settings" text on it.
- On entering the settings you will see the navigation options, on click enter you will direct to that settings page.
- In that settings window page, go through Systems page by clicking on it and then go through About section that is visible on left-hand side.
- Under "Windows specifications," you'll find the version and edition of Windows installed on your system as shown in below screenshot.
- If your system has 64bit version and OS edition above windows 7 then your system supports the installation of docker toolbox.
2. Hardware-Assisted Virtualization in Windows
Enable Hardware assited virtualization for installing Docker toolbox. We can enable this hardware assited virtualization in 2 ways, one is GUI mode and other one is CLI mode using commands.
i) Using Windows Task Manager
- Enter Task Manager in Windows search box and navigate to that page.
- After that go through performance section. Under CPU graph, we can see out whether the virutalization is enabled or not as shown in the below screenshot.
ii) Using Windows Commnad Prompt
- Open Command prompt in your system.
- Navigate to C: drive and run the following command to known the status of virualization:
systeminfo
- The following screenshot illustrate it clearly, on running you will get detailed information regarding in the system, In that check whether hypervisor is enabled or not. If it is not enable make sure to enable it.
Step 1: Downlod Docker ToolBox
- Go to the site https://www.docker.com/products/docker-toolbox in your browser and download the Docker toolbox software
Step 2: Launch The Docker Toolbox Setup Wizard
- After you have downloaded the installer, let's start the installer and go through it, So the first page that's going to show up is a welcome screen and you have the option of helping docker to improve the toolbox this is entirely your wish to check you uncheck the box, click on the next button,
- Then here you're going to want to pick based on your preference, and create a desktop shortcut it's up to you, to add docker binaries to the path, that's a good idea to have an upgrade boot 2 docker VM.
- Click on the Install button, then the docker toolbox is keep on installing, the following screenshot illustrates clearly.
Step 3: Verify Docker Toolbox Software Installation
- Now you have installed the docker, let's verify the installation, to docker the QuickStart terminal application we'll open that application.
Step 4: Initializing Docker Toolbox
- And it is going to run through the initialization process that it needs to get docker up and running on your machine for the first time, you might have to verify a few interfaces depending on your Windows security settings, once docker is initially set you are going to be given a docker shell.
Step 5: Verifying Docker Installation
- This is one of the options that you to interact with docker can now go and type `docker --version` and it's going to verify that you have docker installed in your system, you can use this command in your CMD and PowerShell as well.
- In my opinion, PowerShell and command prompt make it a little bit harder to interact with the docker commands but that's all based on preference.
- Try on the following command to check whether the docker is successfully installed through docker toolbox or not.
docker --version
