Docker Hub vs Docker Desktop Vs Docker Enterprise

Objective of this article is to explain about Docker Desktop which is also known as Docker for Windows or Mac, Docker Enterprise and Docker Hub.

What is Docker Desktop?

Docker Desktop is also known as Docker for Windows/Mac. Docker desktop is the Community Edition(CE) of Docker and it’s designed to run on Windows 10 & Mac OS. Docker desktop provides an Easy-to-use development environment for building, shipping and running Docker containers. For more information about how to setup Docker Desktop, Click Here

Note: Docker desktop or Docker for windows will not compatible on below Windows-10 version. It may cause problems while installing or running containers in prior windows-10 version. So, make sure you are using Windows-10 version.

What is Docker Enterprise?

Docker Enterprise is the Enterprise Edition(EE) of Docker and it’s designed to run on Windows & Linux OS. Docker Enterprise Edition is paid and good to use when we are using multi-OS, multi-Linux or multi-cloud environments.

As per official Docker blog, Docker Enterprise Edition (EE) is the only platform that manages and secures applications on Kubernetes(K8s) in multi-Linux, multi-OS and multi-cloud customer environments. As a complete platform that integrates and scales with your organization, Docker Enterprise Edition gives you the most flexibility and choice over the types of applications supported, general used, and where it’s deployed.

What is Docker hub?

Docker hub is nothing like a app store/market place of docker container images. Docker hub is also known as Cloud-based application registry and development team collaboration services. We can access docker hub by using the below URL.

Docker ToolBox for Windows

Docker Toolbox is for older Mac and Windows systems that do not meet the requirements of Docker Desktop for Mac and Docker Desktop for Windows. Mostly windows Home edition doesn’t support Docker Desktop.

Please follow below link to install docker tool box in windows :

https://docs.docker.com/toolbox/toolbox_install_windows/

After the installation ,following issue might occur in windows .

Issues :

1. When we run Docker QuickStart terminal after the installation, following error pops up in command
2. Unable to start the VM: C:\Program Files\Oracle\VirtualBox\VBoxManage.exe startvm default –type headless failed:
3. VBoxManage.exe: error: Raw-mode is unavailable courtesy of Hyper-V. (VERR_SUPDRV_NO_RAW_MODE_HYPER_V_ROOT)
4. VBoxManage.exe: error: Details: code E_FAIL (0x80004005), component ConsoleWrap, interface IConsole
5. Details: 00:00:01.943299 Power up failed (vrc=VERR_SUPDRV_NO_RAW_MODE_HYPER_V_ROOT, rc=E_FAIL (0X80004005))
6. Looks like something went wrong in step ´Checking status on default´… Press any key to continue…

Resolution :

The above error is because of Hyper Vision . We need to enable HyperVision in windows with the below steps:

->Run a command prompt as administrator and execute:

dism /Online /Disable-Feature:Microsoft-Hyper-V

Note : For some cases ,you will get Feature name Microsoft-Hyper-V is unknown. when you trying to disable Hyper-V from Powershell. Please run below command

DISM /Online /Disable-Feature:HypervisorPlatform

->Reboot windows and type below in command prompt /powershell as admin.

bcdedit /set hypervisorlaunchtype off

If the above issue is not resolved after enabling hypervision then please follow below steps

-> Open C:\Program Files\Docker Toolbox

when docker toolbox was installed it should be as “${DOCKER_MACHINE}” create -d virtualbox $PROXY_ENV “${VM}”

Please edit start file as “${DOCKER_MACHINE}” create -d virtualbox -virtualbox-no-vtx-check $PROXY_ENV “${VM}”

-> Run bcdedit in powershell as admin mode,If hyper vision launcher type status OFF then its fine. If it is AUTO then run bcdedit /set hypervisorlaunchtype off to change status to OFF.

-> Reboot the system and start docker quick start

Docker Kitematic installation

Objective:

The objective of this article to understand Docker Kitematic. Kitematic is a graphical tool that will help to manage docker containers without using Command Line Interface (CLI).

Details:

Docker Kitematic will play major role in Docker administrator work as part of the download, run and administer Docker Containers. Since this tool provides UI to maintain Docker containers, there is no need for using Command Line Interface.

Installation:

Docker Kitematic installation is very easy to do in Windows. Follow the below steps to install Docker Kitematic in your system.

Step 1: Make sure your docker is running. And right-click on the docker icon symbol to choose the Kitematic option. Look at the below image for reference.

Step 2: As on when we click on Kitematic as shown in the above image, it will point to an alert box with the Download button along with the path where do we need to extract Kitematic files into. Look at the below snapshot.

C:\Program Files\Docker\Kitematic

Note: If you have installed your docker other than C:\Program Files, you can place Kitematic unzipped directory under the path of docker installed.

Step 3: Now repeat the first step again, it should take you to the Kitematic login/dashboard page. If you have any problem with starting Kitematic, just restart the docker once and repeat the same.
Note: As shown in the below image, you may get the problem while starting the Kitematic. If you are getting a similar screen, that means you are trying to start Kitematic before Docker getting started. Please wait until Docker is getting started and then try to start Kitematic.

Kitematic Login Page: Kitematic also uses the same Docker login credentials. If you already logged into Docker, this step may not be shown to you and it can take you directly into the Kitematic dashboard which shown in the next image.

Kitematic Dashboard:

Docker Kitematic installation is successfully completed. Thanks for visiting. Happy Learning…. 🙂
