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.

I'm still using VirtualBox. Could you elaborate why Docker is better?

Leaving containers vs VMs aside, docker for Mac leverages a custom hypervisor rather than VirtualBox. My overall experience with it is that it is more performant (generally), plays better with the system clock and power management, and is otherwise less cumbersome than VirtualBox. They are just getting started, but getting rid of VirtualBox is the big winner for me.

Fixing the file system is going to be a very hard/impossible task.

They should just go with nfs mounts it is at least 10 times faster than what they have now

I wish they just adopt what dinghy did, xhyce with nfs mounts and dns server

I always thought of production ready to be stable, of all things. Feature complete is not a part of it. Basically, if you can live with the shortcomings a release has (bugs, performance, lack of features) you can use it in production as long as it's stable (and secure).

I wouldn't consider pegging a CPU until restart to be 'stable'.

But this release aside, I was more commenting on the whole concept of production ready.

I'm not completely disagreeing with you but Debian in recent years has taken massive steps backwards as far as production stability. Jessie for example did not ship with SELinux enabled which was a key deliverable for Jessie to be classed as stable / ready for production, what's worse is it doesn't ship with the require SELinux policies - again another requirement before it was to be marked as stable, it's filled wit…

Unfortunately, nobody has stepped for SELinux maintainance. If this is important for you, you should help to maintain those policies. All your remaining points are vague at best.

Oh believe me, we did try to contribute to Debian, in recent years the community has aged poorly and become toxic and hostile, where the Redhat / CentOS community has grown, is more helpful and we have found them to be more accepting of people offering their time than ever.

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.

I use Docker a lot. I also use things like Docker volume plugins and have had to modify code due to API changes/breakages.

"Production ready" in the "container space" for me are Solaris Zones, FreeBSD Jails, and to an extent lxc (it's stable, but I've used it less). I like what Docker/Mesos/etc. bring to the table, but when working with the ecosystem, it takes work to stay on top of what is going on.

It is even harder to consult with a customer or company interested in containers and give the most accurate near/long term option. It becomes a discussion in understanding their application, what approach works now, and guidance for what they should consider down the road.

Networking and Storage are two areas with a lot of churn currently.

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.

Not to mention the lack of host:container socket sharing and the fact that the Moby VM time drifts due to system sleep. I love Docker for Mac, I use it every day, and it's definitely still beta quality.
