coreos-install and networking

[simon.l...@blablacar.com]

Hello,

I'm using coreos on baremetal servers but I have some difficulties to set advanced network configurations like bonding.

Currently, the installer puts the cloud-config file on disk and this one is loaded on first boot, after the network interfaces.

The consequence is that you have to reboot in order to have a working bonding config or to set up the interfaces manually the first time. 

( https://github.com/coreos/bugs/issues/36 )

I don't know if the problem is with systemd-networkd but anyway, I think the files creation part of the cloud-config should be done during the install (before the reboot on disk) if we want a really consistent node even at the first boot.

What do you think about that ?

We are in the process of designing a replacement for cloud-init/cloud-config that will be able to run prior to boot. On many systems this will be during the initrd but could conceivably be run even earlier during coreos-install. This is a ways out still I promise we are working on it. :)

As a workaround until we have a new configuration system you can mount LABEL=ROOT after coreos-install runs and drop any configs you need into etc/systemd/network and similar. If you need to provision a number of machines this could easily be scripted.

Thanks for the answer Michael.

I'm glad to hear that this part will be improved and actually I'm already using the workaround you're talking about ;)
