If you can get a working kubernetes cluster on Windows Server and can point us to a blog post or documentation on how to get that set up, maybe one of us can give it a whirl. I don't see the issue if the endpoint is Yet Another Kubernetes Endpoint.
Most I've heard from the field is mixed-node kubernetes clusters, where some nodes are linux VMs and some are Windows. That should work just fine.
@radu-matei Have you spent any time with this. If so I'd love to hear your progress. If not, I may take a stab at this. I'm a member of sig-windows and familiar with Windows Server Container in K8s.
I looked into this a little. The docs state that the local files are shipped up to draftd
, the server side component and the image is built there. Looking briefly at the code, it does look like the server side component (draftd
) does the building of the image.
It might it be possible to get this to run on a windows server and have the windows specific builds be done there? Then there would need to be some updates to make sure the correct files are built on the right node type. Having two server-side components might not be ideal.
Would any one from the Draft team be able to give some guidance on how this might be designed to work for windows (or mixed cluster)? Am I way off in how this works?
Good thoughts @jsturtevant. I'd actually note that the architecture is about to be changed from a client/server architecture to a client-only architecture via #573, so use cases like building containers from a windows machine could be opened up quite easily by supporting Windows, which is currently blocked via #406.
After that, it's just a matter of creating a custom set of packs with Windows node support. That way, users will be able to bootstrap a windows application with draft create
, then publish it to a windows node via Helm.
With the new announcement for Windows Server 1709 you will be able to mount named pipes in containers, which will allow you to build Docker images inside a container by mounting
\\.\pipe\docker_engine
.(See announcements in the Docker blog post and on Windws Insider 16278 blog post)
If I am not missing anything, this should allow the
draft
server to run in a Windows container and create the image, right?I would love to take a look at this - the problem at the moment is that I haven't worked with Windows agents in Kubernetes, and apart from creating a hybrid cluster (Linux + Windows nodes) with
az
andacs-engine
I don't know how to configure the Windows part manually - manually because you need the latest Windows Server preview to have named pipe support.The approach that came in mind is the following: Azure VM with the default Server 2016 on a v3 instance that supports nested virtualization, create there a Linux + a Windows Server Insider build 16278 and configure the cluster there.
(Putting this here because maybe someone will get to try this before me and hopefully document the process 😄 or can point me to a resource for Windows agents in Kubernetes)
Is there any other blocker for Draft on Windows Server that I missed?
Thanks!
