Hello -

I've been trying to build a custom CentOS packer image for a few weeks, and 
can get just about everything to work, except for the initial 
/etc/resolv.conf requires a network restart to pickup the DHCP .

I'm using latest Packer with Virtualbox OVA... uploading to S3, and 
importing the ova into and amazon AMI ... when I create the instance, the 
networking doesn't work because there are no DNS resolvers set. However, 
after restarting networking, my DHCP Option Sets from Amazon are picked up, 
and all is good.

It was my impression that including cloud-init was all that was required, 
and that networking should "just work", so clearly I'm doing something 
wrong.... not sure if it's the way I'm using packer, or if it's an AWS 
config setting ... 

Any assistance on what I'm doing wrong would be greatly appreciated.

Below is exactly what I see upon starting up a new instance with my AMI ... 


[centos@ip-10-0-0-7 ~]$ cat /etc/resolv.conf 

# Generated by NetworkManager
search ec2.internal

# No nameservers found; try putting DNS servers into your
# ifcfg files in /etc/sysconfig/network-scripts like so:
#
# DNS1=xxx.xxx.xxx.xxx
# DNS2=xxx.xxx.xxx.xxx
# DOMAIN=lab.foo.com bar.foo.com

[centos@ip-10-0-0-7 ~]$ sudo systemctl restart network

[centos@ip-10-0-0-7 ~]$ cat /etc/resolv.conf 

; generated by /usr/sbin/dhclient-script
search ec2.internal
nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 4.2.2.1





Thanks -

Matt
