Restarting Docker Daemon Fixes Network Problem Inside Containers
Hi,
We are building docker containers on CentOS 7 based machines. Sometimes the docker being built cannot install packages because of some kind of network failure. I just found that restarting the docker container fixes the problems and the builds are successful.
Does anyone have a clue what the root cause of this might be?
Ta,
Andrew

I’ve had trouble before when settings in /etc/sysctl.d were disabling ip_forwarding, which will break Docker’s networking in some configurations.
You may also want to check firewall rules if you have some configuration management tool controlling them.
