Hi Roman,

>> https://bugs.launchpad.net/fuel/+bug/1359725 (Docker dies during the
upgrade)

I saw the problem 2 times, including the one which is in the ticket. I ran
upgrade
more than hundred of times and haven't seen the issue.

>> https://bugs.launchpad.net/fuel/+bug/1357357 (Upgrades, sometimes docker
allocates the same IPs for different containers)

Personally I haven't seen it, and believe that the probability to get
the error is very low, lets say 2 to 100, the issue which I see
really often is [1] ports duplication and it has the same symptoms.
We were able to debug it today and Matthew submit patches.

And if this issue will happen really often, we will increase the
priority and will fix it asap, but for now we have really annoying
random problems like [1].
