Please support PowerShell core on SDK images

[AceHack]

Please add powershell core on both linux and windows SDK images

[AceHack]

Please also make this the default cmd handler in the image

We would like to hear more requests from the community on this before making a change. Making the Powershell the default SHELL would not be something we would consider as we feel it is not what the Linux community would expect.

[AceHack]

Would it be possible to create an alternative tag/image that has PowerShell as the default? This would make it so I would not have to create my own base image for all my apps that does the same. Thanks.

[MichaelSimons]

If there is a strong demand for such images then it would be something we would consider. In general we try to limit the number of images permutations as deciphering the differences between all of the images can be difficult.

[AceHack]

Just to give a little context, I use PowerShell so I can create one Dockerfile that works on both Windows and Linux containers even though in many cases the builds are complicated and require scripting. Before I had to maintain two different Dockerfiles and script the same actions in two different languages. Thanks.

Assume we did add powershell to our SDK images. Why would you need the default shell to be powershell in the dotnet images to enable your scenario?

[AceHack]

Because on Windows the executable name is powershell and on Linux it’s pwsh. So at a minimum I would have to have two base images that set the default shell accordingly and then the multiarch tag. Then all my services would need to reference the multiarch tag.

I can see how that would be nice, but it's well within your capability to solve. It's not so challenging that it's worth us creating a whole series of additional images to update. We'd have to create ~20 new images to make that work.

[AceHack]

If you add powershell to the base images for the sdk but don't make it the default could you run the following

#!/bin/bash
ln -s /usr/bin/pwsh /usr/bin/powershell

This will alias pwsh as powershell and I should be able to set the default myself in a way that would work on both OSs in a single docker file.

Thanks.

That may be a middle ground.

First, we need more requests to add powershell. This request is the first one I am aware of.

Same request to add powershell :)

I second @AceHack on supporting powershell on Linux. It just enable a lot of possibility for development. It also help us make a stronger business case to adopt container technology in our company.

Same here...this is a much-needed feature for consistency of experiences.
