Re: [openstack-dev] [Fuel][Bareon][Ironic] The future of integration module

[Oleksandr Berezovskyi]

Hello,

At the beginning of the work, we've taken fuel-agent driver from Ironic
team and customized it.
Here is main features, which were created during development for Cray (all
of them are now part of bareon-ironic):

   1. deploy-config could be stored in multiple places (image meta,
   instance meta and node meta) and top-level attributes are being merged
   according to priorities in ironic.conf;
   2. default deploy-config support;
   3. support for both two-image (kernel+ramdisk) and three-image
   (kernel+ramdisk+squashfs) agents boot;
   4. rsync deployment support (insecure and secure);
   5. kernel parameters for tenant image and pxe boot could be appended
   with info from ironic.conf;
   6. pulling of agent log in case of unsuccessful deployment;
   7. on-fail script support (list of actions, which are being executed in
   case of unsuccessful deployment);
   8. actions support (set of actions being executed):
  1. actions at deployment time (after deployment);
  2. actions during node lifetime via vendor-passthru interface;
   9. compatibility check between agent version and driver version;
   10. deployment timeout mechanism;
   11. deployment termination mechanism (requires patches to nova and
   ironic);
   12. multi-boot feature (multiple OSes could be deployed to implement
   quick switch).

In case of any questions feel free to ask.

Best regards,
Oleksandr

[openstack-dev] [Fuel][Bareon][Ironic] The future of integration module

[Evgeniy L]

Hi,

I would like to bring up discussion on Bareon [0] and Ironic integration
and plans for the future.

But first let me provide background information on the topic. Bareon is
partitioning/provisioning system [1] which is based on Fuel-agent [2],
currently it's in active development and will be used in Fuel 10.0 instead
of Fuel-agent (as partitioning/provisioning system).

There is integration module for Bareon and Ironic [3], based on this module
Cray team implemented another version [4], which is going to be merged in
separate repository.

Ideally there should be a single module which is used for Bareon and Ironic
integration.
In order to do that, the differences has to be identified and based on that
decisions are made (on deprecation and/or backports).

I would like to ask for help from Cray and Ironic (Ironic -
Bareon/Fuel-agent maintainers) teams to identify the differences and help
with future plans on integration.

Thanks,
