Meet at the Paris Open Source Summit

2016/11/16

Ok, you see, I’m late ! Not only in producing new versions of software but also to make this type of single announce😩 But it’s cloudy these days, that may explain that;-) So after having presented during the DACH OpenStack day in Berlin, I’m today (!) leading again this year the Cloud track at the Paris Open Source Summit with great speakers such as Christophe Sauthier (Objectif Libre) who won a POSS award yesterday, Bruno Gillet (Red Hat) who had already a session last year and Julien Corioland and Pascal Sauliere (Microsoft) whom I’m curious to hear about MS’ FLOSS strategy !

So come in Room GrĂšce at 1:30PM if you want to follow that 2 hour session. Or tomorrow in the main conference room at 11:35AM as I’ll animate a round table around OpenStack Coopetition with again Christophe Sauthier (Objectif Libre) (not just because he won a price, because he has interesting stuff to share about leading CloudKitty !), Patrick Petit (Mirantis), who knows a lot on integration work on OpenStack, and Julien Niedergang (SUSE) who is at the heart of a downstream distribution work with OpenStack.

And last but not least, If you haven’t attended live (you should have!) the keynote of Axelle Lemaire, delegate ministery for Digital in France, sponsor of the event, please do so (as soon as it’s available) as since the creation of all these events in France back in 1998, this is by far the best one. Energizing, visionnary, balanced, with a very dynamic expression, contrary to most years, nobody was sleeping in the room ! Kudos to Benjamin Jean, Jean-Christophe Elineau ad the team for getting her on stage, as I suppose it’s not an easy task, but we need more of such talented speakers. And she contributes to make +1 for women in the men/women balance in that event, which is an additional nice point.

Meet during the upcoming OpenStack Summit in Barcelona

2016/10/12

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 !)

Feeling FLOSS-orphaned

2016/10/01

Bdale has announced today that he was leaving HPE again. 2 years after he came back all of us FLOSSers inside HPE are orphaned again. He didn’t stay longer than Martin Fink and thus we have now lost the best and most influential FLOSS ambassadors inside the company.

I hope we’ll be able to persue their great accomplishements, as HPE is always considered a fair FLOSS player, helping communities, involved on many projects, pushing GPLv3 (“Copyleft is good” said Martin Fink at LinuxCon EMEA in 2015), partnering with important FLOSS vendors, or with important projects like Bdale with Debian, in summary playing its role inside the overall Open Source community.

I wish to both of them to enjoy their retirements, and hope to cross again their paths soon in upcoming events, where I’m sure, they will always be received as the advocates they are deserve. And many thanks for everything you did to make some of our dreams real.

Meet during LinuxCon EMEA

2016/09/23

After having talked on project-builder.org during the latest LinuxCon NA in Toronto, it’s now time to prepare for LinuxCon EMEA in Berlin.

I’l again talk about packaging, this time “Packaging for Linux Distributions with Docker“. And I’ll also replay the now popular (!) “101 Docker training” I’ve also delivered in Toronto, this time trying to deliver it before the one JĂ©rome Patazzoni from Docker is doing on Docker orchestration, in order to allow for a complete overview of the Docker ecosystem.

Of course I’ll enjoy attending many sessions on various topics, and will see if in EMEA as well Docker Orchestration is the new Eldorado this year (In Toronto many talks and booth were dedicated to that theme). At least my colleague Mike Bright will cover it well !

See you around !

Docker 101 tutorial for the masses

2016/09/12

I already mentioned last year that I initiated a tutorial to help discovering Docker. This was based on the work done in the Docker Dojo during a Grenoble Docker Meetup. It has evolved to really become a nice tutorial that you can easily play on your own, with your Linux laptop, using a trial and error approach. We’ve got lots of positive feedback on it, such as the one expressed publicly by Herman Robers.

Of course, the best is when we deliver it, as it creates a lot of interactions between trainers and trainees due to that😉 But it’s still valuable alone. I’ve delivered it during the latest LinuxCon NA, and will replay it for LinuxCon EMEA on the 7th of October.

Now that you are keen to try it yourself, I can give you the URL: https://github.com/bcornec/Labs/tree/master/Docker ! Enjoy and feel free to make pull requests.

Project-Builder 0.14.1 is now out for LinuxConNA !

2016/08/19

Well, in fact I froze that version back in July, but didn’t officially announced it till today (vacations were just in the middle). So that version 0.14.1 is now available, it breaks compatibility with previous ones, so you’ll need to update your VMs/VEs with it as well if you want to use it correctly (that’s why it’s still version 0.x !)

But I’ve been able to build a lot using docker containers with that version, and I’m now more and more happy with these results. Especially because it’s easier to fully automate an environment from absolutely nothing except project-builder.org to working packages. I already described it when I released 0.13.1 last year through a short tutorial, but it’s really working reliably now for a large set of distributions:

But I’ve not really worked yet on the ideas expressed when I issued 0.13.2 in February this year.

Instead I’ve done other improvements such as managing signed deb repositories (was asked for a long time), have a better naming for temporary versions (allowing easier updates between temporary versions and also with stables, but creating the incompatibility with 0.13.x), docker tests for lots of distributions (paving the way for automatic testing here from nothing to package build), adding support for pbr, standardizing temporary directory names, …

That will be the version I’ll use to make demos during my presentation next week at LinuxCon North America in Toronto as already announced. Come to see it live and so that we can discuss continuous packaging !

OpenStack Summit proposals

2016/08/07

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 https://www.openstack.org/summit/barcelona-2016/vote-for-speakers/ 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 !

Network install of Debian 8 on a HPE ProLiant Gen9 server

2016/06/29

There are articles to do this in a pure Debian environment, such as the excellent one I used as a base from Raphaël Hertzog.

But my deployment server in that case is a CentOS 6 one, so I needed some adaptations to make it work.

My target system is a HPE ProLiant BL 460 Gen9, equiped with bnx2x NICs (Broadcom BCM 57840 10/20 Gb/s cards). And during a network boot install, I have had messages indicating that the firmware was missing (failed to load bnx2x/bnx2x-…)

So in order for my system to network boot, I needed to adapt my initrd and add the missing firmware in it (Debian’s policy prevents the distribution of
non-free firmware, which these are). The Firmware in my case is available as a standalone package at http://ftp.fr.debian.org/debian/pool/non-free/f/firmware-nonfree/firmware-bnx2x_0.43_all.deb (hint from this article)

So on your non-debian deployment server, you can do the following:

mkdir /tmp/fw
cd /tmp/fw
# This is the network boot environment required for booting Jessie
wget http://ftp.debian.org/debian/dists/jessie/main/installer-amd64/current/images/netboot/netboot.tar.gz
[...]
tar xvfz netboot.tar.gz
[...]
# Keep the kernel in your deployment infra
mv debian-installer/amd64/linux /where/your/tftpboot/k/debian-8
# Extract the initrd to modify it
wget http://ftp.debian.org/debian/pool/non-free/f/firmware-nonfree/firmware-bnx2x_0.43_all.deb
[...]
mkdir initrd
cd initrd
gzip -cd ../debian-installer/amd64/initrd.gz | cpio -ivdum
[...]
# You need the dpkg commdand to make your life easier (part of CentOS, Fedora or Mageia)
dpkg -x ../firmware-bnx2x_0.43_all.deb  .
ls lib/firmware/
[...]
# Should show you the firmware in the right place
find . -print | cpio -o -H newc | gzip -c9 > /where/your/tftpboot/i/debian-8.img
[...]

Now you can add an entry to your boot loader (grub2 in my case) for the network boot part (more info on Network boot and Debian at https://wiki.debian.org/PXEBootInstall)

menuentry 'Debian 8' {
  insmod gzio
  insmod part_gpt
  insmod ext2
  insmod iso9660
  linux /k/debian-8 ip=dhcp --
  initrd /i/debian-8.img
}

If you have another firmware to deal with, refer to the dedicated Debian page at https://wiki.debian.org/fr/firmware

After that your system should be able to network boot and install your Debian Jessie distribution on it.

The next step is to automate the installation, which consists just in changing the linux line in the grug conf file:

linux /k/debian-8 ip=dhcp auto priority=critical url=http://deploy-server/ks/debian-8 --

where the debian-8 file under the ks directory is just the preseed file you’ll build for your automatic installation.

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

2016/06/19

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, JĂ©rĂŽme 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 !

Microsoft recrute … des RHCT/RHCE

2016/06/12

Si, si ! Et c’est mĂȘme Ă©crit ici

De lĂ  Ă  penser qu’ils vont basculer dans une adoption large et massive des technologies que nous promouvons, il y a un pas que je ne franchirais pas. Pour avoir discutĂ© rĂ©cemment avec certains de leurs reprĂ©sentants d’Azure justement, je pense qu’il y a encore beaucoup de chemin avant qu’ils comprennent et ensuite admettent les vertus de ce que nous prĂŽnons.

Quant au job, dans ces temps difficiles, c’est toujours bon Ă  savoir, mĂȘme si pour un job de “Technology Solutions Professionals” il vaut mieux avoir “Une formation complĂ©mentaire dans la vente, services de livraison, les affaires ou marketing” ! En clair c’est de l’avant vente pour justifier auprĂšs de clients combien Azure est la bonne solution pour hĂ©berger des environnements informatiques basĂ©s sur Linux. Et dire qu’ils ont au moins 25% de leurs clients qui les croient et qui l’ont fait ! J’espĂšre que les autres hĂ©bergent eux-mĂȘmes, ou font appel Ă  des solutions plus ouvertes, ce n’est pas le choix qui manque.

Il est vrai que je ne devrais pas ĂȘtre la cible d’une telle campagne, ayant un job bien plus intĂ©ressant que cela, mais visiblement, ils ratissent large sur LinkedIn, et n’ont sans doute pas compris mon activitĂ©đŸ™‚

Bon, moi je retourne Ă  mes patchs pour Ironic, Biforst et DiskImageBuilder;-)
