Docker uses the 172.x.x.x ip space and Yale is also using this range for private ip space. If you used the Docker official repo it would have created a docker0 interface with a 172.x.x.x interface. i.e. sudo Ifconfig docker0 docker0: flags=4099<up,broadcast,multicast> mtu 1500 inet 172.x.x.x netmask 255.255.0.0 broadcast 0.0.0.0 This overlaps with Yale networks and causes routing to fail since it tries to route out of the docker0 interface and go’s nowhere. The fix is to just use a 192.x.x.x ip on the docker0 inteface Do the following. </up,broadcast,multicast> - sudo su -
- systemctl stop docker
- sudo su -
- Ifdown ifdown docker0
- ifconfig docker0 down
- cat << EOF >> /etc/sysconfig/network-scripts/ifcfg-docker0
TYPE=Bridge DEVICE=docker0 NETMASK=255.255.252.0 IPADDR=192.168.5.1 ONBOOT=yes BOOTPROTO=none NM_CONTROLLED=no DELAY=0 EOF - Ifup ifup docker0
- systemctl start docker
