spandhe | Hi everyone! | 22:03 |

spandhe | qq.. does cloud-init support IPv6? | 22:05 |
smoser | spandhe, "sort of". | 22:19 |
smoser | if you're not feeding networking in via confdig-drive or something then really thats just a matter of the image config. | 22:19 |
spandhe | I am using config drive | 22:20 |
smoser | and inserting a /etc/network/interfaces ? | 22:20 |
smoser | it could work. there might be some issues with ubuntu images. | 22:20 |
smoser | but largely if /etc/network/interfaces is going to come up fine, then that should work. | 22:20 |
smoser | MAAS is using cloud-init in ipv6 only scenarios. | 22:20 |
spandhe | one odd thing I observed is, inside the disk. cat /etc/sysconfig/network doesnt say networking_ipv6=yes | 22:21 |
smoser | so it is possible. | 22:21 |
smoser | then that (sysconfig) probably needs some work for it. | 22:21 |
smoser | it is work that needs to be done "really soon now". | 22:21 |
spandhe | I see that /sysconfig/network-scripts/ifcfg-eth0 has the right info.. but probably because ipv6 is disab;ed in network file, network config is not happening correctly.. | 22:22 |
spandhe | smoser: is that something to be done on cloudinit side or nova side? | 22:22 |
smoser | spandhe, well, that is probably cloud-init reading a /etc/network/interfaces style file provided to it by nova/neutron | 22:23 |
smoser | and rendering it. | 22:23 |
smoser | to sysconfig style | 22:23 |
smoser | the going-forward plan for this is to have a better declaration format for netwroking | 22:23 |
smoser | than "/etc/network/interfaces". | 22:23 |
smoser | https://review.openstack.org/#/c/85673/13/specs/juno/metadata-service-network-info.rst | 22:24 |
spandhe | smoser: can u point me to the code where this rendoring happens? | 22:24 |
smoser | probably in cloudinit/distros/rhel.py | 22:25 |
spandhe | smoser: thanks! :) I found https://github.com/number5/cloud-init/blob/master/cloudinit/distros/rhel.py#L94-L98 | 22:27 |
spandhe | doesnt seem to do NETWORKING_IPV6=Yes | 22:28 |
spandhe | smoser: adding NETWORKING_IPV6=yes seems to help.. should I open a bug? | 23:03 |
smoser | spandhe, sure. | 23:04 |
