I need to have Jenkins and Java on a Windows container and I am investigating whether to use Windows Server Core or Windows Nano Server.
So that the assembly of the container is fast and the movement of DEV to PRO is agile. I see better Nano Server because it occupies 300MB instead of Server Core that occupies about 5 GB.
The problem comes when I want to install something in Nano Server. I tried to install Chocolatey but it is only compatible with the Server Core version, which makes me think that it is not advisable to use Nano Server for this functionality.
Is it advisable to use Nano Server to have Jenkins and Java or is it intended for another use?
The first reason (possibly among quite a few) why you should use Windows Server Core is that Nano Server does not support MSI installer files, which makes installing Jenkins more difficult.

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 want to use ucma API on windows container.But I want to know, can I host the API on nano server or windows server core?
I searched ucma documents but I didn't find any information about containers.
According to requirements, it seems to work only with Windows Server 2016 and Windows server 2012.
So I was able to get a UCMA application to start/register and even accept a call running on a server core container, but it took some doing. The runtime needs to be installed in the container image, which needed to be done manually. You also need to provision the app using the container host's details, and get the cert into the container.
The place where it all breaks down though is with media-if your app needs to play/record prompts for calls, you can't do it from server core. Container or not, the OS is missing the runtime for WMA, and from what I've found, it can't be installed.
For what it's worth, the SFB team doesn't even support UCMA on server core, let alone core on a container, so you're dealing with a couple of layers of "not supported" stuff.
UCMA applications will work fine on Windows Server Core as long as your application doesn't have any UI.
Nano Server I'm not sure.
As far as I know, Nano Server only runs 64-bit applications. UCMA application can run in 64 fine but what I don't know is what .net framework is supported on nano server. If it supports the full .net framework, it may work.
I don't think you will know unless you try it yourself and see if it works or not.
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 need to use Docker / Windows containers on Windows 2016 Server and prepare it Windows applications to run on it.
Configuring Windows via Powershell just is not as convenient though as it is on Ubuntu, especially if you never worked with Windows Server really and need to learn all the Powershell commands ;)
Is there a way to access a Windows Container via GUI?
It's possible with Docker, Ubuntu, VNC:
Can you run GUI apps in a docker container?
Wondering if anything similar can be done for Windows Containers?
(I am working on-premise, not using Azure. Found a similar but unanswered question here: https://stackoverflow.com/questions/32721422/windows-server-containers-azure-how-to-create-a-container-with-gui)
Thanks.

RDP is definitely not an option as per February 2016 - not sure if they plan to support it in the final release?!
https://msdn.microsoft.com/en-us/virtualization/windowscontainers/about/work_in_progress#remote-desktop
Remote Desktop
Windows Containers cannot be managed/interacted with through a RDP session in TP4.
So far I managed to have at least a decent file explorer by using Midnight Commander, but still command line on Windows is not much fun.
in this video MS-container-developer Taylor Brown says that they break up with RDP from TP3 to TP4 and will very probably do not support RDP in RTM Version Server 2016:
https://channel9.msdn.com/Events/TechNetVirtualConference/TechNetVC2016/Day-3-Containers-Session-with-QA
Update as of Dez. 2018:
Server 2019 is out and RDP is still not possible / supported for all container images. (of course it does not make any sense for nano images)
check this nice intro to what has changed: https://stefanscherer.github.io/docker-on-windows-server-2019/
to have a somewhat complete overview, it should be mentioned that there are some hacks out in the wild, that may RDP make work in some images and setups, e.g.:

Everytime I run any rails command on my windows vista dev box there is always something like a 30 second delay before the command does anything. I don't have the firewall enabled and the virus protection is disabled. Any thoughts on what could be causing this?
Thanks
I can't comment on this specific issue, but I can say I had nothing but problems trying to run Rails on Windows in the past. That said, after trying Ubuntu and MacOs, I still prefer to use Windows as my primary UI. My solution is to run Ubuntu Server on a VM, and use a Samba file share to access dev files, with putty as my primary console interface. The linux command line is far more powerful, and is where the Rails ecosystem is really geared to be running.
VirtualBox: http://virtualbox.com
Ubuntu: http://ubuntu.com
Samba: http://www.samba.org/
Putty: http://www.chiark.greenend.org.uk/~sgtatham/putty/
With these tools, you can run your Rails stack in a nice linux server environment, and still enjoy the utility and functionality of the Windows GUI. (Although I'd recommend you move from Vista to 7)
