Docker Read-Only File System

[richardgavel]

I don't see anything that suggests this is something that goes in the Dockerfile, just a container runtime feature. Now it's possible that CoreCLR has code within it that tries to open files in a non-read-only mode...

This could possibly be achieved by specifying volume mounts corresponding to every directory that ASP.NET and your application may write temporary write files to.

@RehanSaeed if you want to give it a shot, we can help you through issues you encounter along the way.

@csharpfritz and @HongGit what are your thoughts on this?

[RehanSaeed]

Typical ASP.NET Core apps don't use any temporary directories that I'm aware of. Volume mounts should work but I don't know which directories .NET Core needs write access to.

[shirhatti]

Ah sorry. This is the repo for ASP.NET, not ASP.NET Core. You're probably looking for https://github.com/aspnet/aspnet-docker
