The reason we are keeping the beta private is because we don't believe the quality is good enough yet to "open the floodgates". We are sending as many invites as the engineers are comfortable with - currently that's several thousands per day. As we hit more and more edge cases (performance, stability, support for unusual configurations...) we are expanding the pool as fast as we can.

I'll second your ask for patience.
If you've been following along, incredibly smart people have been experimenting with Docker and xhyve for a long time now.
I feel like I've been waiting for close to a year for a solution this good. Testing and trying lots of permutations on a Mac.
I was very excited by the beta announcement and was fine waiting for Docker to send invites at whatever pace makes sense for them.
I'll also still patient while the Docker team works out the countless new bugs they will find as people use this far and wide.
I'll also keep doing my part to help people be very successful developing and deploying with Docker.
Thanks for the hard work.
I'm deep in the weeds with Docker, LXC, containers, hypervisors all the time. Content about those layers very few people care about... These are tools that are supposed to mostly stay out of the way after all.
Interest in Docker packaging their app as a nice mac app, and people understanding how the install process works is not a problem, it's a sign that these tools are finally becoming digestable by all.
What's the technical error?
But note that beta 8 was released a few days after that review and already introduced some changes.
Also, for the Windows beta, it very much is still a beta.
That's why it's a beta.
If it really worked (especially on Windows) Docker would post the binaries instead of treating this like Wonka Golden Tickets. Love Docker, am actually waiting to be approved so I can get to building something, but posts like this are a symptom of a larger problem.
