I am new learner for Docker.I have a very simple question.
I want my application to work on Linux system but I am writing application in Windows.So do I need to install Docker for Windows or Linux?
If I run using Docker for Linux,i am not getting option to run in windows and it is getting failed(I understand it might be some other unrelated error) but I need to confirm if my approach is correct or not.
Am I right in installing Docker for Linux?
Also,in case I plan to move to AWS, what docker I need in that case.
Thanks
Consider docker as any software. if your OS is windows you install windows version of a software. if your is a linux distro then you install linux version of a software.
So you need to install docker for windows afterwards you can install any docker image/container you want under your operating system. Could be windows, linux or anything else.

I want to ask about cross platform compatibilty of Docker ,means if an application is designed to run in a docker container on windows,then can it run on linux or vice -versa?
Docker was create to run on Linux, so the short answer is yes.
The Windows version isn’t stable or recommend (Docker for windows). At least not by now.
“But, Fischer, I use Docker on Windows!” Yes, with WSL (windows subsystem for linux - Some kind of VM), which you can configure to set a memory limit, using the .wsconfig file, and if you look at your Windows Menu you may found a Ubuntu icon, that connects you to the bash.
Docker is largely used for people that develop software, and today many languanges and frameworks use linux, even Microsoft with .Net runs on Linux.
Docker was created to resolve one simple issue: "But it works on my machine." So, it means that a container should run on every platform. At least "it works on my computer" lol
I think the question is regarding a Windows application. If that's the case, a Windows application cannot simply run on Linux containers. For example, .Net Framework doesn't run on Linux. If an application was targeted for Windows, it needs to run on Windows and in that case only a Windows container can run the application.
Docker Desktop can run both: Windows containers and Linux containers, just not at the same time. You have to switch the context so Docker Desktop can target either WSL (for Linux) or HCS (for Windows).
I installed the latest version of Docker for windows in my windows 10 machine. It seems the new Docker Desktop toolbox doesn't contain the Quick start terminal. Every documentation says to check the quick start terminal option at the time of installation. I dont see any option to check that option with the latest Docker toolbox.
Is there any way we could install Quick start terminal for windows.
Or are there any other alternate to the QS terminal. My objective is to build, tag and push / pull docker images to a gitlab registry. Powershell, command promt doesn't work because its a windows machine.
with the new Docker-for-desktop versions there's no need for the added toolbox as marked here
Legacy desktop solution. Docker Toolbox is for older Mac and Windows
systems that do not meet the requirements of Docker for Mac and
Docker for Windows. We recommend updating to the newer applications,
if possible.
You can just open any typical terminal in your OS of choice and use the docker cli if you can't remember the exact usage try docker --help 😉
it is possible to install docker desktop on virtual machine (vmware) windows 10 on a VMWARE ESXI ?
i am trying to install desktop docker on my vmware virtual machine with windows 10.
I installed the wsl2 support but at the end of the installation docker crashes with the following error:
Docker desktop 4.0.1
Installation failed
Component CommunityIstaller.ServiceAction failed to start services: The service did not respond to the start or control request in a timely fashion
I have done several tests but I cannot avoid this crash in any way.
The Operating System is a build that meets the minimum requirements to install Docker.
However, I noticed that Hyper-V is not enabled in the windows features. can this be a problem?
I think maybe it's a grafted virtualization problem because I install docker inside a VM. it's possible?
How can I solve? (or do you think that i will fix this problem with linux virtual machines?)
Does your host machine have all the advanced flags for 'efficient' nested virtualization? I wouldnt really recommend a third layer install of docker (as the final container is then virtual , on paravirtual (wsl2) on virtual (HyperV), on virtual (Esxi). I heavily assume the performance will be terrible.
And yes: You need Hyper-V, it's a requirement still. I assume, as you say its not available on the features, youre running a windows 10 home? Then sorry, you need at least Windows 10 Pro for Hyper-V support.
But as youre running a ESXI host, go the better performing way: Install any Linux distro of your choise, install docker there - if you wanna use it for Visual Studio etc. , you can still remotely debug etc. - and its performing better than on an a even deeper nested virtualized windows-wsl2. And btw: if its because of GUI, simply install the free Visual Studio Code, it offers Docker Tools which offer you many configiruation and monitoring options in a GUI , without enforcing you to do such a super deep nesting.
Yes, it's definitely possible. I'd probably check the hardware assisted virtualization (if available) is enabled. If so, you might want to make sure you've satisfied the rest of the requirements for the WSL2 backend deployment. If you're still having issues, try an older version and try upgrading from there.
I'm trying to work on a project, and the setup steps begin like this:
Clone the repo
Set up Docker
Run make
Being a Windows user, I installed Docker for Windows, and it installed WSL2 to get all the Linux stuff set up. But when I went to run make from the WSL shell, it couldn't find it. So I tried to get make from apt-get... and that wasn't there either!
It would appear that my WSL2 install is broken. Unfortunately, Googling for it hasn't turned up much of use. So how do I obtain apt for WSL so that I can build my toolchain?
Something similar happened to me: I installed Docker Desktop in Windows some months ago and it configured WSL to run behind it. However, it was WSL version 1 instead of version 2, and it did not install any Linux distro, since both apps run on top of WSL.
So please, go through the tutorial on the manual installation of WSL to check if all the steps are actually configured.
Before that, you can already check what version of WSL you have installed and its state, by running, in CMD or PowerShell:
wsl -l -v
After you set WSL v2 as your default version (Step 5 of the tutorial), you can make sure that Docker Desktop uses it. For that, check this link on the Docker Desktop WSL 2 backend, more specifically the Install section.
Regarding the make part of your setup, I believe that you can do that in a system of your preference. If you want to do that on WSL, I recommend you install Ubuntu running over your WSL (Step 6 of the tutorial).
Once you installed Ubuntu or other distro, you can run it as any other app. There, you can manage your apt, make and other installations right as in Linux :)
I am getting error as Docker needs 64bit configuration, is there any way where i can install docker in 32 bit systems. It's a 32 bit i3 processor having windows 7 machine.
As per the document of docker, it says that you can install it only on 64 bit machine.
But there is another solution if you don't have a 64 bit machine. Just use the below url to play with docker (it's official site) it works like a charm
Docker play
Edit 1: Please note that this is only for practise purpose, Once your session is over your work will be lost.
Edit 2: I have found a very interesting site to practise docker kodekloud
The first step to getting this whole setup to work is installing Oracle’s VirtualBox on the host system. Once the installation is complete, installing docker-machine is as simple as running the following in an Administrative PowerShell session:
choco install docker-machine -y
docker-machine create --driver virtualbox default
docker-machine env | Invoke-Expression
For more details You can follow this blog.
No, this is not possible for current versions of the docker.
This was possible for early versions of docher (boot2docker 32bit iso), but the project is closed and thoroughly killed
