My main concern is coming across a an issue only to research it and find a "won't fix"[closed] and 100 +1s asking for it. When I have something super important in actual production this scares me way too much to trust.
1000x this. Pretty much sums up my experience with Docker so far.
Great concept, poor execution.
That's where the competition will come in handy. Docker Inc has its own corporate goals. Luckily, they are decoupling the underlying components more and more.
Just curious: Which issue(s) are you talking about?
One that comes to mind is folks asking for relative path support in Dockerfiles (though I understand why the Docker folks don't want to do that).
