Configure boot2docker for dns-gen

README.md

Init boot2docker

Create boot2docker instance and start it

$ boot2docker init --dhcp=false --hostip=172.16.0.1
$ boot2docker up

Configure the instance

$ boot2docker ssh
$ sudo cp /opt/bootlocal.sh /Users/{username}/

Edit the bootlocal.sh now in your home to add this line:

ifconfig eth1 172.16.0.11 netmask 255.255.0.0

Now create a profile file with this content:

DOCKER_TLS=no
EXTRA_ARGS="--bip=172.17.42.1/16 --dns=172.17.42.1"

Go back into the boot2docker ssh

$ sudo cp /Users/{username}/bootlocal.sh /var/lib/boot2docker/
$ sudo cp /Users/{usename}/profile /var/lib/boot2docker/profile
$ exit
$ boot2docker restart
$ sudo route -n add 172.17.0.0/16 172.16.0.11

Check that it worked:

$ ping -c1 172.16.0.11
