CentOS7 purge leftover ifcfg-x files from docker image #56

Closed fbladilo closed 8 years ago

fbladilo commented 8 years ago

It would be nice to purge leftover ifcfg-x files from the docker image, it causes issues specially with systemd enabled containers using centos7 as a base. Below is an example along with systemd failing to start the network.service because of a bogus ifcfg-ens2 already baked in the centos7 image :

[root@0ea52bb network-scripts]# cat ifcfg-ens2 TYPE=Ethernet BOOTPROTO=dhcp DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no NAME=ens2 UUID=d7d058b5-723e-4776-b332-af376d635b9f DEVICE=ens2 ONBOOT=yes PEERDNS=yes PEERROUTES=yes IPV6_PEERDNS=yes IPV6_PEERROUTES=yes

This is done in the latest and 7 tags. The other tags:

$ docker run --rm -it centos
[root@67e760754286 /]# cd /etc/sysconfig/network-scripts/
[root@67e760754286 network-scripts]# ls
[root@67e760754286 network-scripts]# ll -a

Hi, how to change the default NIC name in centos-7 containers since ifcfg-x files have been purged from the base image?
