Add details on running in Docker Windows containers

[friism]

This is based on work by @PatrickLang done here: https://github.com/PatrickLang/MusicStore/tree/plang-temp-compose

[rs38]

could it be modified to work with FROM microsoft/dotnet:1.0.0-preview2-nanoserver-sdk ?

[friism]

@rs38 Yeah, that works great too. You have to run the windowsservercore-based sql server image though, so it doesn't matter greatly.

[rs38]

isn't therey any SQL based on nanoserver+.NET core image? Still looking for a nice, non-trivial POC for nano+container, which does not get bigger than roughly 1 GB

[friism]

isn't therey any SQL based on nanoserver

@rs38 Microsoft SQL Server does not run on Nano Server, as far as I know.

[rs38]

that's why I mentioned "any". Any in-process SQL would do, as well as not being bound to IIS but may be Kestrel. I need to admit I am not quite sure which prerequisites EF has related to SQL

[friism]

@rs38 if you interested in a pure nanoserver-based sample, can you open a separate PR doing that? There's a list of EF supported databases here: https://docs.efproject.net/en/latest/providers/index.html

[rs38]

I am afraid, I do not have a solution to provide

[PatrickLang]

@rs38 MusicStore does have an in-memory database. Look at startup.cs for _platform.UseInMemoryStore . You can hack up the code to enable it. I did that before I had the SQL connection working in containers.

[PatrickLang]

Thanks for doing this, I've been intending to move my version back to Kestrel and rebase it and issue a PR but this looks cleaner

[friism]

@PatrickLang totally! And this was based on your prepatory work for Ignite btw, adding acknowledgement in the description

@pranavkm @Praburaj I already signed the CLA last year, do I need to sign it again?

[pranavkm]

@troydai do you think this would be a useful scenario for our functionals?

If not, perhaps these instructions might be better suited for the https://github.com/aspnet/Home repo. @danroth27 for thoughts on this.

[dnfclas]

@friism, Thanks for signing the contribution license agreement so quickly! Actual humans will now validate the agreement and then evaluate the PR.
Thanks, DNFBOT;

[friism]

Do you have a chance to tryout the Music Store on Windows Nano Server?

@troydai as I mentioned above, Windows Server core base layer is needed anyway for the SQL Server service. The web part runs fine on nano, and I can change it, but it means that for a user starting on a naked machine, they have to pull both nanoserver and windowsservercore base layers

[rs38]

Nano image is less than a 10th of servercore. Who would hesitate? ☺

[friism]

@rs38 one would hesitate because in this specific case, switching to Nanoserver causes Docker to download more stuff on an empty system (because windowsservercore is required no matter what for SQL Server)

Alright, @taylorb-microsoft convinced me to change to nanoserver because it starts and builds faster. Also pulled in some compose improvements from Patrick. For now, this requires master builds of compose: https://dl.bintray.com/docker-compose/master/

[rs38]

this cannot (completely) run on nanoserver (without hyper-v like as e.g. on Azure) as long as there is a dependency to a windowsservercore based SQL db.

[PatrickLang]

Are there any objections to merging this if the AppVeyor build is fixed?

[friism]

It looks like the Appveyor build has been broken for approximately 5 months...

[glennc]

@muratg Are the guys responsible for build breaks not looking at these?
