The EPEL and CentOS Project relationship

On Saturday 31st Jan, after close of Fosdem day 1 – I am working to bring together a group of people who all care about the EPEL and CentOS Project relationships to try and workout how best to move things forward. Key points to address are how SIG’s and other efforts in CentOS can consume, rely on, feedback to and message around content in EPEL and similarly how can CentOS efforts feedback into EPEL components – the overall aim being to workout a plan and a way for the two buildsystems to talk to each other ( the CentOS Community one and the EPEL one ), and to set some level of expectations across the project efforts.

Everyone is welcome to come along for the conversation, but it would be most productive for people who are CentOS SIG members and EPEL contributors / administrators and users who rely on EPEL content on their CentOS Linux installs.

I’ve started a thread to setup some of the basic topics on the centos-devel list, you can track it here. And there is a list of people who want to make it for the conversation at the bottom of the CentOS Fosdem 2015 planning page. If you are able to make it, let me know and I will add your name to the list. Remember this is a post-fosdem day 1 thing, in the early evening of the 31st Jan 2015.

See you there!

CentOS in OpenShift Commons

Happy to announce that the CentOS Project is now a part of the OpenShift Commons initiative.

In their own words :

The Commons builds connections and collaboration across OpenShift communities, projects and stakeholders. In doing so we’ll enable the success of customers, users, partners, and contributors as we deepen our knowledge and experiences together.

A significant amount of OpenShift development and community delivery work is now done on CentOS Linux, and I am hoping that this new association between the two projects allows us to further build on that platform.

EPEL Orphaned packages and their dependents to be removed Dec 17th

Hi,

The EPEL repository runs from within the Fedora project, sharing resources ( including, importantly their source trees ) with the Fedora ecosystem; over the years its proven to be a large and helpful resource for anyone running CentOS Linux.

One key challenge they have however, much like CentOS Linux, is that the entire effort is run by a few people helped along by a small group of voulenteers. So while the package list they provide is huge, the people putting in the work behind it is small. A fallout from this is that over the years a significant chunk of packages in the EPEL repo are now orphaned. They once had a maintainer but either that maintainer has gone away now, or has other priorities.

A few days back, Steven announced that they were going to start working to drop these orphaned packages unless someone steps up to help maintain them. You can read his announcement here : https://lists.fedoraproject.org/pipermail/epel-devel/2014-November/010430.html

This is a great time for anyone looking to get involved with packages and packaging as a whole and wanting to contribute into the larger CentOS Linux ecosystem to jump in and take ownership of content ( ideally stuff that you care about, hence likely to keep it managed for a period of time ). They have a simple process to get started, document at the Joining EPEL page here : https://fedoraproject.org/wiki/Joining_EPEL and you can see a list of packages being orphaned on the urls from Steven’s post linked above.

Regards,

The CentOS-7 Release Announcement

We would like to announce the general availability of CentOS Linux 7 for 64 bit x86 compatible machines.

This is the first release for CentOS-7 and is version marked as 7.0-1406

First, please read through the release notes at : http://wiki.centos.org/Manuals/ReleaseNotes/CentOS7 – these notes contain important information about the release and details about some of the content inside the release from the CentOS QA team. These notes are updated constantly to include issues and incorporate feedback from the users.

———-
Updates, Sources and DebugInfos

Since the upstream EL7 release, there have been some updates released – these have been built and are being pushed to the CentOS mirror network at the moment. They will be available within the next 24 hrs. From this point on we will aim to deliver all updates within 24 to 48 hrs of upstream releases.

For the first time, this release was built from sources hosted at git.centos.org, however srpms being a byproduct of the build and also considered critical in the code and buildsys process are being published to match every rpm we release. Sources will be available from vault.centos.org in their own dedicated directories to match the
corrosponding binary rpms. Since there is far lesser traffic to the source rpms compared with the binary rpms, we are not putting this content on the main mirror network, however if users wish to mirror this content they can do so using the reposync command available in the yum-utils package. All source rpms are signed with the same key used to sign their binary counterparts.

Debuginfo packages are also being signed and pushed. They should be online by the end of this week, July 11th.

Yum configs for both sources and debuginfo packages are included in the default centos-release package on every install.

For the CentOS-7 build and release process we adopted a very open process. The output of the entire buildsystem is made available, as its built, at http://buildlogs.centos.org/ – we hope to continue with that process for the life of CentOS-7, and attempt bringing CentOS-5 and CentOS-6 builds into the same system.

———-
Numbering

CentOS 7.0-1406 introduces a new numbering scheme that we want to further develop into the life of CentOS-7. The 0 component maps to the upstream realease, whose code this release is built from. The 1406 component indicates the monthstamp of the code included in the release ( in this case, June 2014 ). By using a monthstamp we are able to respin and reissue updated media for things like container and cloud images, that are regularly refreshed, while still retaining a connection to the base distro version.

In order to facilitate Special Interest Groups to further extend the CentOS Linux platform, we are also using component codes. The main distro is, therefore, titled ‘Core’. SIGs would be able to adopt any name they need and deliver that by overriding the base centos-release rpm.

Download

In order to conserve donor bandwidth, and to make it possible to get the mirror content sync’d out as soon as possible, we recommend using torrents to get your initial installer images:

Details on the images is available on the mirrors at http://mirror.centos.org/centos/7/isos/x86_64/0_README.txt – that file clearly highlights the difference in the images, and when one might be more suiteable than the others.

Coming Soon

We are currently working to extend the portfolio of content we deliver for a major release. In the past its only been iso media and install tree’s, but with CentOS-7 we are also going to deliver:

= Docker Images

= Cloud Images in vendor ecosystems ( HPCloud, RackSpace, AWS, Google Compute etc )

= Cloud Images for direct download and consumption in on-premise infra ( RDO/OpenStack, CloudStack, OpenNebula and Eucalyptus )

= Given the popularity of the minimal install ISO in CentOS-6, we are going to try and deliver a minimal install ISO for CentOS-7 as well. One key challenge here is that the installer image has grown to nearly 360MB, and getting enough content into a CD size image is proving hard.

= A community build system is in the works, we hope to have that functional by the end of this month ( July 2014 ), allowing us to set up a contributor base in the Special Interest Groups to extend and further develop layers and variants on CentOS Linux

= Special Interest Groups including Xen on CentOS, CentOS Storage and CentOS Atomic Host are starting to gain traction, expect to see content delivered from those groups in the near future.

= As a part of the expanded Core efforts, we are also going to attempt to deliver a CentOS-7 release for 32bit x86, ARM and PowerPC in the coming months.

If you are interested in joining any of these efforts, signup for the CentOS-devel list at http://lists.centos.org/ and send in a self intro email and what areas you are interested in helping out with.

Dojo

We try and organise Dojo’s in various parts of the world as a one day event, to bring together people who use CentOS and others who are keen to learn about CentOS. The day’s focus is on sharing technical knowledge and success stories. Its also a great place to meet and talk about upcoming technologies and learn how others are using them on CentOS Linux.

04th Aug ’14 Cologne, Germany : http://wiki.centos.org/Events/Dojo/Cologne2014
25th Aug ’14 Paris, France : http://wiki.centos.org/Events/Dojo/Paris2014
29th Oct ’14 Barcelona, Spain: http://wiki.centos.org/Events/Dojo/Barcelona2014

This autumn and winter we also hope to host Dojos in New York City USA, Timisoara Romania and Bangalore, Pune and New Delhi in India. Please keep an eye on the page at http://wiki.centos.org/Events for details on these venues.

Thanks

I would also like to thank our donors and sponsors for their continued support for the project. Its down to their help that we were able to deploy enough resources to run the Public QA process for CentOS-7; as a data point we ran nearly 300 – 350mbps of sustained bandwidth for the last 3 weeks that we?ve had the Public QA running.

And thanks to everyone who contributed with ideas, code, test feedback and promoting CentOS into the ecosystem.

Enjoy!

Can we deliver a PowerPC build for CentOS-7

Hi everyone,

The powerpc platform has always been interesting, but hard to get and while we’ve had some levels of interest in the past, either I struggled to find the hardware to bootstrap the builds, or we were unable to get enough communication going to bring the community of contributors together to kick things off. Now as we work through the mechnics of building and delivering CentOS-7 on x86, we again have the opportunity to try and see if there is a willing, contributor community that can come form up a PPC SIG in CentOS.

We do have some resources ( compute + network + mirror ) to make the backend side of things happen, and the folks at OSUOSL.org have offered us some capacity on their community powerpc builder resources to help as well.

Interested to come help ? Join the conversion on the centos-devel mailing list : http://lists.centos.org/pipermail/centos-devel/2014-June/010625.html

CentOS Community buildsystem bootstraping by the CERN Linux team

Hi Everyone,

We would like to welcome onboard the CERN Linux Distro team ( http://cern.ch/linux ) to the CentOS Core SIG. Thomas Oulevey and Jaroslaw ‘Jarek’ Polok are going to be bootstrapping the CentOS Community Buildsystem around Koji and helping run it going forward. The community buildsystem is going to be the central place for all source to binary builds used by all efforts other than CentOS Core ( for now ).

The initial target is to get a test instance running in the coming weeks, and then work on the git.centos.org integration, with the aim of having the ‘production’ buildsys online soon. This is the build service that all SIG’s and Core SIG builds will consume going forward ( with the exception of CentOS Linux, we have quite a bit of work to do before we can migrate that ).

Communications on this effort will be on the centos-devel mailing list ( http://lists.centos.org/mailman/listinfo/centos-devel ) and on the #centos-devel irc channel on irc.freenode.net. Hardware resources for the effort have been identified, setup and access is being setup so things can start rolling fairly quickly. Mike McLean and Fabian Arrotin are going to be working with them.

You can keep up with Jarek on his google+ page at https://plus.google.com/+JaroslawPolok/ and Thomas tweets at https://twitter.com/thomasnomas ; They both also contribute to the http://linux.web.cern.ch/linux/ blog.

Please join me in welcoming Thomas and Jarek to the CentOS Project.

Helping the larger ecosystem upgrade

As we get ready for CentOS-7 ( hope everyone is keeping their eyes on http://seven.centos.org/ ) I’ve been wondering what we can do from the CentOS Project side of things to help the larger ecosystem adapt, facilitate and grow into CentOS-7 once its released. And what we might be able to do in the interim to help with testing and porting efforts that people might be undertaking right now, as they too get ready for CentOS-7. There are some really cool things coming in CentOS-7, and it would be great if we can, as a community ensure that people are able to use these features in the best possible manner. And also educate people about these new features, so they are able to make the right choices.

So with that in mind, are you someone who is a part of or contributes to an open source community or effort, who rely on CentOS-5 and/or CentOS-6 ? How can we help you get on the CentOS-7 targets ?
