How to change resolv.conf for existing docker containers

I recently upgraded docker version on my Ubuntu to latest 1.9 version. During the upgrade docker network bridge gateway has changed from 172.17.42.1 to 172.17.0.1. I had some existing containers where the resolv.conf still points to 172.17.42.1 so whenever I restart my container the resolv.conf is resetting to 172.17.42.1. I tried to modify the /var/lib/docker/containers/<containerid>/resolv.conf […]
