Maybe a better question is what needs to be done/what are the outstanding dependencies?

Since last time I looked into this, containerd gained support for Windows 10 1809/Windows Server 2019, so it's possible no MS involvement in buildkit is needed, if it can get...

Ah, thank you. moby/moby#38541 is the PR reference I was looking for earlier. Poking through, containerd doesn't seem to publish Windows binaries in [their releases](https://github.com/containerd/containerd/releases) despite having thew new Windows...

Quick correction: Containerd *does* have nightly builds for Windows, they're at https://github.com/containerd/containerd/actions?query=workflow%3ANightly

With #1314, and some more hacking on things, I've gotten to the point where my next failure is coming from inside containerd, or the connection to it. ``` PS C:\Users\paulh\Documents\BuildKit\supersimpleDocker>...

The failure I hit in my previous run turned out to be a bug in hcsshim, for which I have posted a fix at microsoft/hcsshim#752. So now I am able...

It probably doesn't, but only because all the file-copy APIs in BuildKit fail an assertion on Windows related to permissions support. I really should get back to this, it got...

Now I'm looking at this again, I realise I previously only tested building into the buildkit cache. Outputting also does work: * image, oci, and docker outputs all filed calculating...

I got image, oci, and docker outputs working in containerd in https://github.com/containerd/containerd/pull/4399, so I can now _run_ the (trivial) images I build. So then back to working out how to...
