Sadly, the state of things, be it the Docker ecosystem or others, "ready for production" means something much different than it did years ago. For me, the definition of ready for production, Debian is a good example of the opposite end of Docker.

>> Debian is a good example of the opposite end of Docker. It is not fair to compare Docker with Debian. Docker Inc (who backed Docker) is a for-profit corporation and is backed by investors. It is understandable why they need to push their products into production the soonest time possible.

What does it matter how fair it is? It's neither fair to compare a monkey to a fish in terms of being able to climb trees, but that doesn't change that one of the two is most likely already sitting on a branch. And ultimately, if you need something that can climb trees, a fish simply won't do, no matter how fair you try to treat it.

I think by 'production', they mean 'ready for general use on developer laptops'. No one in their right mind is deploying actual production software on Docker, on OS X/Windows. I've been using it on my laptop daily for a month or two now, and it's been great. Certainly much better than the old Virtualbox setup.

Since the whole point of Docker would be to deploy these in production and not just for development, I don't see how the term 'ready for production' can be used. Isn't this just a beta?

I doubt the problems mentioned happen on Linux or CoreOS, which is likely what a production environment will run on.

Can I expect a dockerfile that 100% works on Linux to 100% on Mac and Windows?

Short answer, yes. Medium answer, images your Dockerfile is based on are still run in a Linux environment, even if it's virtualised differently.

Wait now, hold on a minute. I'm very confused and curious how does this work?

Can I run any linux-based container on Windows? Can I run (are there any?) windows-based containers? If so, does it work the other way around: windows container on linux host? Does it somehow use the recently published Linux Subsystem for Windows, or is it completely different compatibility layer? If it is different, doesn't it seem like a waste of effort?

On Windows, Hyper-V doesn't really play nicely with laptops. If you've got it enabled and bridged to your wifi adapter, Windows 10 may think that your connection is Ethernet and turn off all bandwidth saving features. I only found out after Windows Update had exhausted my monthly LTE quota.

No, on windows you still have to run a Linux vm which the containers will run inside. Meaning all containers actually run on a Linux host. The new Docker for Windows app only abstract away some stuff so it feels easier working with.

> does it work the other way around

No
