Well I used Docker on top of Mesos so I have quite a bit of experience and the above were all problems I faced. They're not impossible problems obviously but they take time and thought to solve. From your responses, I am not sure you fully appreciate the problem to be honest.

You have to remember that you containers and coming and going all the time, which is one of the biggest challenges. It basically means you have to have everything centralised and that means a lot of additional infrastructure/complexity.

Wouldn't it be fair to say these are all problems faced with any / all deployments? When are logs never going to be a problem or security or state? I appreciate the problems (honestly!), but when it's presented as docker-specific, I get confused. Yes.. all these things need to be managed.. at the end of the day you're changing your stack from running 5 systems to running 5 processes acting like 5 systems. This is going to take some thought, but I genuinely believe there's a greater reward at the end of the tunnel in this realm than there is the old world of puppet master / slave.
