This will allow docker to be used to build consistent deployment WIMs and WinPE images

Currently, we only know the existence of mcr.microsoft.com from documentation, we need a portal for search images with different tags.
Oracle just have a simple one.

Need Edge in a container for automated UI testing

All container network interfaces ("vEthernet (Ethernet)") use MTU 1500 by default. There is no way to configure a default MTU other than 1500, despite Docker and Microsoft documentation which indicates that this should be possible: https://docs.microsoft.com/en-us/virtualization/windowscontainers/manage-docker/configure-docker-daemon, https://docs.docker.com/engine/reference/commandline/dockerd/#description.

This is a huge pain point for users running on platforms that require an MTU less than 1500. The only solution at this time is to set the container interface's MTU first thing every time one runs a container, for every container.

I would like to gather performance metrics from a windows container. Something like this project. https://github.com/google/cadvisor

Many Business Application are dependent on Office to edit files or import/export of ppt or word formats. So adding office support for Containers would be a good idea.

We would like to run selenium tests in isolated displays as is currently possible for Chrome and Firefox in docker-selenium or dosel.

Also, it would be great to video record the entire desktop to troubleshoot failing tests.

HCSShim errors in Docker is very uninformative. The only thing we get is an error code which is mostly unhelpful. Writing additional error information would be very good for debugging. For example I get The parameter is incorrect error from HCS but no idea what that parameter is. You can find complaints similar to this one in Docker GitHub repository.

We have legacy .NET based business applications making extensive use of MSDTC. It will be good to have support for this role in containers to enable Lift & Shift scenarios.

I would like to have support for the --privileged command on windows containers. I would be nice to have this feature on a build server.

Currently with OS upgrade, customers need to update Dockerfile to use the new base image and rebuild docker image.

It will be a painful process for enterprise rebuild & redeploy containers with existing customers on it.

The new OS should be backward compatible especially considering the semi-annual release cadence.

Docker is unable to mount VHD or other block devices inside of a container. This would be useful for isolating several disk related tasks that can cause issues. (This does not require device pass-thru like DDA)

This would allow for Windows Full Flash Update (FFU) image creation to be performed inside of a container.

The MSMQ-Server role is a prerequisite for Particular NServiceBus installation. As NServiceBus handlers are potentially a good fit for containerization, it was disappointing to find that it is not possible to install MSMQ-Server in a container. Please create a base image with this support!

Please enable "Server" service so container file system can be accessed from host and this is also prerequisite for other UI management tools which are disabled due to that like EventViewer for example

At the Moment Containers have a single file size limit, which is somewhere between 7 and 8GB. When you have Files bigger then that, you won't be able to create Images. This way all Database usage won't be possible, because Databases are rarely less then 7-8GB in size. Also when you want to use media it might have more then 7-8GB. So it would be great to have no single File size limit in Containers
