Add support for Windows Server 2019 about aspnet-docker

[Mozanrath]

Where can we see a list of images on mcr? Is there a web UI like docker hub?

[sanguedemonstro]

I'm with you @sixeyed , actually I'm waiting, and ready to test my apps on it.
Please put it at Docker Hub too!

We have the PR staged at https://github.com/Microsoft/aspnet-docker/tree/RS5update and are working on bootstrapping new infrastructure to publish to Windows Server 2019

[radyz]

Any ETA on this?

Thanks

[radyz]

Excellent, looking forward to download it once it's ready

[shirhatti]

Windows has pulled the 1809 base images. We're waiting for them to republish with new base images before we can publish.

[radyz]

Thanks a lot!! I've been refreshing docker hub everyday checking for it to be available 😄

Any ETA on this?

Thanks

it's here: docker image pull mcr.microsoft.com/dotnet/framework/aspnet:4.7.2-windowsservercore-ltsc2019

[Mozanrath]

Still not on docker hub yet

[shirhatti]

@Mozanrath The images are already live.

As you may have noticed in the docker pull command, the image is now being served from the Microsoft Container Registry (MCR). Starting with Windows Server 2019 and going forwards, all new tags will be published exclusively to MCR. All existing tags have been syndicated from DockerHub to MCR.

If your existing Dockerfile begins by specifying microsoft/iis as the base layer as shown below-

FROM microsoft/aspnet:4.7.2-windowsservercore-ltsc2016
…

Our guidance is to move to adopting MCR as your base layer. You should change your Dockerfile to what’s shown below-

FROM mcr.microsoft.com/dotnet/framework/aspnet:4.7.2-windowsservercore-ltsc2016
…

As part of this transition, we are only changing the source from where you download your images to MCR. DockerHub continues to be the preferred medium for container image discovery.
Take a look this blog post for the motivation behind this change.

@rotata Could you help answer with that question?

Starting with Windows Server 2019 and going forwards, all new tags will be published exclusively to MCR. All existing tags have been syndicated from DockerHub to MCR.

Hey @shirhatti, or @rotata, how can I list or explore all images and tags from mcr.microsoft.com?

[biiiipy]

@sanguedemonstro as I've read elsewhere, Docker Hub is still the place to explore/search images and mcr is just a place where they get pulled from. It's kind of weird and unexpected, but makes sense in a way

[sanguedemonstro]

@biiiipy from ltsc2019 on, tags are no longer in the docker hub. So now it is hard to know if there is any variant of ltsc2019, like other languages as pt-BR... Maybe there is but who knows?!
