Docker on Arch Linux - docker0 just doesn't seem to want it's IPv4 address

Recent instability running Docker on Arch -- docker0 just doesn't want to keep it's IPv4 address.

tl;dr - My setup of Docker on Arch Linux is having some issues, around docker0 not properly holding on to it’s IPV4 addresses (listed as inet in ip addr output). I originally though it was a problem with Alpine CDNs, but it was actually docker0 throwing up repeatedly. Short term work around I’ve found is to just create the missing link again, w/ sudo ip addr add dev docker0.
