python-redfish reaches 0.4


But this is only an intermediate step !

It has been a long time since I talked about Redfish and our python-redfish library.

Slowly, but surely we have made progresses to make it more usable. Of course, still not enough to have the Ironic community happy with it, but at least we’re back on track to integrate patches that we have started to receive from community members.

So we’ve published today our version 0.4 of python redfish, and made it available on pypi with its doc as well as packages for CentOS 7, Fedora 25, OpenSUSE 42.2 and Mageia 5 (.deb packages are for the next release). And of course the sources also on github.

And as you can see, it has become an OpenStack project, using then all the tools they set up for software development (git, gerrit, jenkins, …), which explains why it took us some time to migrate everything from our original github env to this one.

Not everything is done yet, we still need to migrate some bug reports, to review and improve some patches, provide our test infrastructure and start, as said, fixing some of the bugs reported by the community. This is what is in front of us for 0.5.

Hopefully, when reaching 0.6 we should be able to come back to the Ironic team to let them evaluate our progresses and see whether we”ll then be good enough to be used by them. Still work to do, but we do that on our free time, so progresses are as they can be (and with the help of contributors, are much quicker than I could have thought !)

Continue to help us help you 😉

Pretty busy week no ?! And you should be able to replay the labs/tutorials on Wednesday afternoon during the OpenLab session in Lab 1.

A lot of sessions are covering Docker related topics this year, and I’m happy with thatas it’s a great techno, even more with the recently announced 1.13 bringing service support to docker-compose !

For those of you wondering why and MondoRescue versions are not published more regularly, that gives you again a hint 😉 Not speaking of the travel for 2 weeks starting the week after this one, and the next event in March in Grenoble, TES, where I’m part of the Event team and that we’ll organize for the 8th time.

See you there to talk of these subjects or something else as you see fit. I’m around the whole week.

Meet during the upcoming OpenStack Summit in Barcelona


For the first time, I’ll be speaking at the OpenStack Summit during the main conference.

I’ll talk about the possibility to add Redfish support to Ironic.

I’ve already talked about Redfish, either the standard, or through our python-redfish module, even during a vBrownBag session of a previous Summit in Vancouver.

This time I’d like to detail the latest news around the standard itself, how it can be used in an Ironic context and what we’ll have to do to make it work, up to its usage for Alexandria, a CMDB as a service solution we’re also developing in conjunction with these components.

I’ll also attend most of the Ironic dev round table to organize that work, and understand better what the community is expecting from us with regards to the development, and answer to the questions around the specification. Should be a very interesting week in Barcelona (on top of the fact Barcelona is a great city I encourage you to visit !)

OpenStack Summit proposals


While I’m in vacation around Barcelone, I’ve made before leaving proposals for the upcoming OpenStack Summit which will be … in Barcelona !

If you think they are valuable for the OpenStack community, let them know by voting for them 😉 Here are they:

  • The nightmare of Ironic Standalone
  • Empowering Ironic with Redfish support
  • From Bare Metal to CMDB: ITIL as Code

The easiest way to vote is to go to and search for cornec in the search area on the top left. You’ll just get these 3 ones. But of course there are tons of other interesting presentations proposed and as usual it will be difficult for these one to be selected. And you should really vote for the ones which are the most interesting.

Hopefully even if not selected I’ll be able to come back in this great place and meet again with peers after Paris and Vancouver but of course, it will be much more difficult without being a presenter. Let’s see !

Meet again next week in Paris and at LinuxCon NA 2016 in Toronto


I’m just back from an HPE Event (the ETSS in Gothenburg, Sweden) and will soon have to start the next ones.

First, I’ll be this week in Paris to talk during a MySQL Meetup to cover automatic deployment, in particular with Redfish, images of reference (and a bit of MondoRescue) and automation (ansible e.g.) for DBA.

Then I’m again lucky this year to be retained as a speaker for the upcoming LinuxCon North America which will be in Toronto, Canada from the 22nd of August to the 27th. I’ll have a session on Continuous Packaging, mandatory for DevOps and a 3 hour Initiation Lab on Docker. Interestingly enough at the same time, Jérôme Petazzoni, Docker, will do one on Swarm !! Maybe we should coordinate and make them one after the other (I’d like to attend his Lab BTW !!)

I have now put all my lab material that I do for HPE on GitHub, to make it easier for attendees to report errors, and for others to use them and learn. I have content for Docker (Done with René Ribaud, Yann Allandit, Michael Bright), Git (Done with Clément Poulain), Redfish (Originally written by François Donzé and done with René Ribaud) and soon for Ironic.

Hope to be able to meet with you here or there !

python-redfish reached 0.3, first interesting version for others


Back in 2015, during our internal TES event in Grenoble, a group of people gathered to talk about the new Redfish DMTF standard and how we could add its support into Ironic.

Since that, we have worked first on a new Open Source python library to interact programmatically with Redfish 1.0 based systems.

We tried to promote it during OpenStack Summits but except in Vancouver when I did a short video explaining that, not enough interest from the community. Of course we had very few to show at that time.

One year after, we have now reached version 0.3 of the project. And while that doesn’t sound a lot, in fact the libray is now usable by others to interact with Redfish based systems.

What it provides:

Our next steps are in multiple directions:

Hopefully, as you’re reading this, you’re interested by the topic, and we’d be happy to get your feedback, and more over your patches in order to improve our work, and speed up the development !

And don’t forget the HPE Open Source project available as well on github which provides much more capabilities, due to its support of the iLO and iLOCM extensions to the Redfish standard.

In order to meet at the OpenStack Summit in Austin, vote for us !


We’ve made 3 different but related proposals for the upcoming OpenStack Summit, and as everybody, we would like to be retained in order to disclose what we’re working on and think could improve the ecossytem.

Our first proposal is “Empowering Ironic with Redfish support” which aims at describing our plans to add Redfish support to Ironic.

The second, which would benefit greatly from the work of the first, is “Alexandria: The librarian bridging OpenStack and CMDBs” which is a nascent new component to allow easily with a plugin based architecture to bridge CMDBs (starting with the great Open Source iTop one) and OpenStack features such as bare-metal deployment with Ironic, managing also automatic inventory. Amitious but pretty useful in our opinion, of course to help manage our Datacenter, but the one of any OpenStack customer as well.

Finally, We’d like to present our overall view on how OpenSTack is at the heart of a Software Defined Infrastructure with our last presentation. This one targets more architects and decision makers, while the 2 others will be more technical and cover implementation details. All will have demos.

Hopefully, you’ll agree with me to find that these topics deserve being elected !! And thus vite for them 😉

In that case, I can just wish we’ll meet over there 🙂 !

Redfish 1.0 is now out and soon used by our projects


Recently the DMTF announced that the Redfish standard had reached version 1.0, the first usable for production.

If you don’t know Redfish yet, and don’t want to read the full spec, I can summarize it very roughly as a cross-manufacturer RESTful API to configure Hardware systems and recover info from them. Pretty cool in fact as this was a missing brick for a full Open Source based multi-platform Software Defined Infrasctrucute.

Now remains for us to update our python-redfish with it, and start supporting more features now it’s stable. That the first step will allow Ironic, the bare metal component of OpenStack, to have Redfish support, which is IMHO a very highly desirable feature. Not for Liberty, hopefully the spec will be ready for M and code sufficiently developed to allow us to win a slot in the Summit !

Then it will also allow us to advance on the other project we’d like to promote: Alexandria, which is a clever (of course, I’m part of the design team ;-)) way to interface CMDBs (well the one who are themselves clever enough to have a parametrized data model such as iTop) and Hardware information providers such as Redfish.

Imagine that you rack a new Refish compliant server (HP ProLiant Gen9 are among the first to provide already a subset of it), cable power and management board, integrate some info on that machine in your CMDB (iLO credntial and IP address e.g.), and ask through Alexandria that the rest is filled by Redfish calls. And kept updated as time passes. Well, that’s exactly what we try to achieve, as this is one of the need we have to maintain our Solution Center CMDB up to date as easily as possible.

Lots of good ideas, but not enough code to show for now. Hopefully, we should be able to have an Alexandria demo with somple drivers ready for the upcoming OpenStack Summit… and be able to travel to exchange our views with other OpenStacker around all this.

Some personal news around OpenStack


I’m trying to be more and more involved around OpenStack, as much as my time allows me of course.

So some recent news about that:

1/ I’m now a member of the Franch OpenStack Association Board and really proud to be listed alongside real long time contributors and advocates of the project.

2/ I’ve become an ATC during the Liberty cycle due to a modest contribution on Ironic. But it gives me the possibility to attend the Tokyo Summit !

3/ I’ve contributed to 3 proposals of talks for the upcoming Tokyo OpenStack Summit: the first one on the work we do to add support for Redfish in Ironic. The second is on a new project called Alexandria which we would like to see becoming an OpenStack project in the future and which is a CMDBaaS solution. Early stage but pretty neat ! And finally, we want to expose our view around a Software Defined Infrastructure with OpenStack.

If you think that any of these 3 presentations is worth listening during the upcoming Tokyo Summit, then vote for us before the 30th of July !!

I’d like to share other thoughts on the big tent and the community, but that will be for a next article.

Software Defined Compute: Redfish and Ironic at the next OpenStack Summit


The future is already here !

In fact here ! This is a new specification which is gaining traction to allow hardware configuration of systems through a RESTful interface. All new HP ProLiant Gen9 servers from HP are providing a first version of what is not yet the standard, but looks very near to it, and provide already a rich interface.

This is pretty exciting, as it will allow people like me working on Disaster Recovery e.g., or people like Devananda van der Veen who is the Ironic PTL (OpenSTack bare metal deployment component) or many others to have, when it’s ready, a single interface to configure the servers from different manufacturers following the Redfish Specification (as of now HP, Dell, Emerson, Intel). And it’s much more feature rich than IPMI, so you would be able to go well farer with it and reach a real Software Defined Compute node.

In order to make it usable for Ironic we’ve started to work on a low level python library (python-redfish) on which we’ll be able to build the Ironic driver for Redfish later on. This is work for Liberty and after of course. And as Ironic can be also use alone, I’m more and more thinking of using it as a way to provide MondoRescue images for bare metal deployment as an additional feature over media boot. Especially if there are plans to have a standalone web interface for Ironic !

If you want to learn more on the HP implementation of the RESTful API, there is a webinar organized Wednesday, April 29, 2015 from 10:00 am CDT to 11:00 am CDT. Register from

And if you want to learn a bit more of where we are on this, read the code (easy for now) or come at Vancouver for the upcoming OpenStack Summit to discover it.
