So this happened today after happily using docker & docker compose for the last year without issues.
Shortly after starting a first container on my machine, docker registers an entry in my host machine’s route table for its veth device:
Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 veth359bc16
The entry persists until I kill the container and completely prevents my host machine from networking.
I’m not sure what’s causing it (other than the most recent system update perhaps), has anyone had to deal with something similar? I’m running on the latest Fedora27 docker version 1.13.1.
