I recently downloaded a Debian WSL, and I love it! However, all of the commands I used to be able to use(git, rustc, rustdoc, etc) don't work anymore. I'm guessing this is a problem with not sharing the regular environment variables and PATH? Should I do something to make Debian use my regular one? Thanks!
I really only want Debian for a Bash Shell with the packages, not as a complete separate environment.

I am a developer who is using Ubuntu 20.04 LTS regularly for my development. I never install any packages like, node, PHP, python in the OS and make use of docker for the purpose. VS Code is the editor I use, and the extension of the remote container will help me to develop & debug inside the docker container.
Right now, I am in the process of moving the development to a windows environment and I wanted to follow a similar workflow there too. Unfortunately, I am facing few issues like "file changes are not getting detected" (when npm serve in angular and react projects).
https://github.com/microsoft/WSL/issues/4739
https://www.reddit.com/r/bashonubuntuonwindows/comments/c48yej/wsl_2_react_not_reloading_with_file_changes/
I have tried different methods to solve the issue like
use wsl2 and then docker inside that and then serve from the container
use just docker and serve the code from inside the container
Regardless of the methods, the file changes are not getting detected inside the docker.
Trust me I have gone through many bizarre words like inotify, increasing the watchers, etc... Nothing helped.
Is there a developer out there following a similar practice in a Windows environment? (docker + windows)
Any help is highly appreciated.
I suggest moving the files to the wsl2 file system and not the windows.
Wsl2 'sees' the windows file system from inside a mount image /mnt/c .
Move out of it, like at ~ (cd ~) and i think your files will be normally watched .
I am trying to package an Electron app that relies on several Docker containers into a single executable. I would like to be able to convert Dockerfile's into executables runnable on Windows. Is this possible? Can I pull this off without having Docker installed on the client machine? How can I do this?
It is not possible.
Take into account, that docker images are packaged for certain architecture. Kernel must be compatible. And sure, you need docker engine to work on client machine. I think windows is not ready for this.

We have a large application with several parts running on a Windows VM and I am trying to evaluate Docker containers for our application deployment. Is it possible to create a base docker image from an existing Windows VM already running my application? (I know this can be done using Dockerfile but I am looking for a quick way to create the image)
https://docs.docker.com/engine/userguide/eng-image/baseimages/
Above link describes creating image from working machine for Linux, but I am looking for something similar for Windows.
The only base image for Windows that I know are the ones proposed by Microsoft, for Windows Server 2016 or 1709.
See "PoC: How to build images for 1709 without 1709"
That means you can translate any Widows VM into an image.
You would need:
a Dockerfile
the right Microsoft base image, which would represent a Windows server one.
Typically:
microsoft/nanoserver,
microsoft/windowsservercore
If you application only runs on a Windows VM, you need to make sure it can be installed and run on one of those base Windows images.
EVen though you are using a VM Windows server 2016, you would not be able to quickly "capture its state": you need a Dockerfile to describe what you want your Widows container to run.
No it's not possible. You have some stuff like Vm2Docker etc but all it does the same thing you will do manually that is enumerate features installed and create some artifacts for you.
But it's not possible to do for third party application as you mentioned. You'd have to disassemble it and figure out how to scripts to install it.
I am looking for a way to have a Development environment of Production web server for our Developers/testers created using Docker on windows.
I have windows server 2016 OS installed on a Physical server (not VM), and want to dockerize it so that Dev team can make changes on it first and once they confirm all working fine then same changes will be done on production web server.
Thanks,
RK.
I am a Windows user.
I have looked at the official Docker tutorial "Get Started". The example focus is a python app. I don't know python and I guess a Docker container can have many programs installed as an environment, not just python.
Is Docker good for testing a program I download from the internet in an isolated environment (like a sandbox in firewalls or antivirus) ?
How for example can I make a container that has an environment containing installed programs like Visual Studio, VLC player, Office, etc.?
Thanks,
Abe
Yes; you can have an isolated environment with docker. You can set your desired configurations, download from internet, install, and whatever you do in a Virtual Machine.
Yes, you can. What your container contains depends on the base image you create it FROM and packages you install inside of it.
Tips
You can build your container from an empty OS (e.g. ubuntu), configure the OS, download/install/configure/run whatever you want.
You can create a base image which derives FROM a suitable OS, then install any basic application (e.g. firefox) which you may use in a lot of containers on it. Then you should push it in a registry (e.g. Github). After that, you can use it as a base image for other containers, so your new containers have installed applications by default; no need to install them again. It reduces complexity and repetitions in Dockerfile.
I am currently trying to understand and learn Docker. I have an app, .exe file, and I would like to run it on either Linux or OSX by creating a Docker. I've searched online but I can't find anything allowing one to do that, and I don't know Docker well enough to try and improvise something. Is this possible? Would I have to use Boot2Docker? Could you please point me in the right direction? Thank you in advance any help is appreciated.
Docker allows you to isolate applications running on a host, it does not provide a different OS to run those applications on (with the exception of a the client products that include a Linux VM since Docker was originally a Linux only tool). If the application runs on Linux, it can typically run inside a container. If the application cannot run on Linux, then it will not run inside a Linux container.
An exe is a windows binary format. This binary format incompatible with Linux (unless you run it inside of an emulator or VM). I'm not aware of any easy way to accomplish your goal. If you want to run this binary, then skip Docker on Linux and install a Windows VM on your host.
As other answers have said, Docker doesn't emulate the entire Windows OS that you would need in order to run an executable 'exe' file. However, there's another tool that may do something similar to what you want: "Wine" app from WineHQ. An abbreviated summary from their site:
Wine is a compatibility layer capable of running Windows applications
on several operating systems, such as Linux and macOS.
Instead of simulating internal Windows logic like a virtual
machine or emulator, Wine translates Windows API calls
on-the-fly, eliminating the performance and memory penalties of
other methods and allowing you to cleanly integrate Windows
applications into your desktop.
(I don't work with nor for WineHQ, nor have I actually used it yet. I've only heard of it, and it seems like it might be a solution for running a Windows program inside of a light-weight container.)
