[14:41] <sde> I need to override the search domain set through DHCP, but of course resolv.conf is generated by NetworkManager from /etc/sysconfig/network-scripts/ifcfg-eth0, which in turn is generated by cloud-init. Been digging, but can't get cloud-init to alter ifcfg-eth0.
[14:41] <sde> This on a Redhat image in AWS
[14:47] <rharper> I don't think the RedHat AWS image has cloud-init new enough to generate networking config; it's likely the ifcfg-eth0 is baked into the image as-is (dhcp on eth0 was a common default in cloud-images).    It may be possible to have a dhcp hook script which can append/prepend DNS settings
[14:49] <sde> The image I'm working on is using cloud-init 0.7.9, which seems to tie with the docs I was looking at that suggested this was possible, and at the top of the ifcfg-eth0 it states it was generated by cloud-init.
[14:50] <sde> I've tried putting in cloud.cfg -
[14:50] <sde> manage_resolv_conf: true  resolv_conf:   searchdomains:     - vpc01.grn.poc.tbaws.com   domain: vpc01.grn.poc.tbaws.com
[14:50] <sde> (mangled format in cut-n-paste, sorry)
[14:50] <rharper> Ah, 0.7.9 is new enough
[14:52] <rharper> it maybe that the fallback network configuration doesn't look at those cloud-configs;  would you be able to file a bug against cloud-init on launchpad with details? https://bugs.launchpad.net/cloud-init/+filebug
[14:54] <sde> Sure, I can do that. Have I got the settings in the right location and format through? I've never looked at cloud-init before today, and I got confused reading the docs about exactly where I should be putting things
[14:58] <rharper> sde: w.r.t format, not quite sure since your paste didn't have newlines.  but I suspect you want it to look something like: http://paste.ubuntu.com/25376871/
[15:00] <sde> Yes, that's exactly what I've got. Directly in cloud.cfg is the correct/acceptable location for that, rather than as a separate file under cloud.cfg.d/ ?
[15:11] <sde> Need to step away, but thanks for your assist, appreciate the time. I'll get that bug raised later. Thanks
[15:11] <smoser> rharper, wrt "what image for development release on ec2"

[15:14] <rharper> ah, search by ami number
[16:03] <smoser> image status is https://github.com/smoser/talk-simplestreams/blob/master/bin/image-status
[16:45] <smoser> rharper, blackboxsw fyi, the instance-data roadmap entry

[19:54] <blackboxsw> rharper: /smoser trial run  ipv6 from AWS metadata :) https://us-east-2.console.aws.amazon.com/ec2/v2/home?region=us-east-2#Instances:sort=desc:statusChecks
[19:54] <blackboxsw> oops
[19:54] <blackboxsw> http://paste.ubuntu.com/25378444/
[19:55] <blackboxsw> looks like generating the network V1 worked
[19:55] <blackboxsw> I'm throwing together some unit test coverage
[19:55] <blackboxsw> ehem, I mean I'm all TDD and must already have the unit tests around some place
