[one-users] CoreOS on opennebula

[Sander Klein]

Hi All,

Well, I've got a CoreOS cluster up and running with some dirty tricks.

AFAICT CoreOS does not support the OpenNebula way of contextualizing the 
image. But it might not be hard to implement. I read the CoreOS 
OpenStack image mounts an ISO which they call config-drive and 
configures the CoreOS machine with that. So, the same should be possible 
with OpenNebula. CoreOS only needs to learn the OpenNebula way of doing 
that.

I just created an empty disk image, attached it to a loop device, 
modified the bare-metal installer script a bit to work with a loop 
device. Then ran the script pointing to the loop device and my 
cloud-config.yaml. Uploaded the image to OpenNebula and started it.

Currently I've got a cluster of 3 machines up and running. But the 
problem is that I now need to create an image and separate config for 
each CoreOS node I want to run. Which is unnecessary since OpenNebula 
can provide the variables needed to only use 1 image with 1 
cloud-config.yaml.

I'll have a look and see if it is easy to teach CoreOS to mount the iso 
and get it's information from it.

Greets,

Sander
