Hey,
Docker is somewhat a hype these days.
And docker can also be found in the Node land. In two ways actually.
First:
Ryan added some Dockerfiles which you can use to build ovirt-node-iso
within a Docker container. That is great. Because it separates the host
OS from the to-be-build-OS.
Ref: http://gerrit.ovirt.org/#/c/24679/
Very nice. So does this removes livecd-tools from the build process?
or does it run livecd-tools through Docker?
Second:
I just added a (draft) plugin which adds Docker to an existing Node ISO
and runs it in "host mode", that means Docker will be bound to a public
port (4243 in out case) and users can use it from remote using:
$ docker -H $NODEADDR:4243 info
This has the benefit of having the solid nature of Node as a base and
the flexibility of Docker on top.
Ref: http://gerrit.ovirt.org/#/c/25370/
IIUC, this would allow containers to run locally on ovirt-node. Is
there any management interface for this? Is this a roadmap item for
engine to consume? Or is it to make Node an option for another
container-based virtualization management tool?
Both ways need testing, and the latter can not be easily tested yet, as
systemd (aka Fedora image) is required.
