I've been already using the "ip" command but I didn't know about the "bridge" one. Hey, but the developers could have done it better: one more character to type now vs the previous "brctl" one; I will create an alias named "brdg"... ;-) At the end, "less" is better than "more".... Thanks for the notice Gianluca

Atomic Download page
by Karanbir Singh 11 Mar '15

11 Mar '15

hi, I've put together a rough wiki page with all the Atomic image download resources that I've pushed for this last build. It also includes Ian's Vagrant images. http://wiki.centos.org/SpecialInterestGroup/Atomic/Download Could this become the generic download url to point people at when looking for CentOS Atomic images ? - KB -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

brctl command in Atomic host
by Gianluca Cecchi 11 Mar '15

11 Mar '15

Hello, I'm testing the latest CentOS Atomic host rolling build (20150228_01). Apparently the brctl command, as normally provided inside bridge-utils rpm package, is not present. I can query /sys/class/net/docker0 and /sys/class/net/veth*/ subtrees, but it would be nice to have it, unless superseded by another docker/atomic command... Thanks in advance, Gianluca PS: I posted here because I'm not subscribed to atomic-devel too atm.. let me know if it's a problem

SIG repo layout and conflicts between projects within a SIG
by George Dunlap 10 Mar '15

10 Mar '15

At the moment, we're essentially using yum repos as the "patch" mechanism to CentOS Base: SIGs populate a repo with packages they want to add / override, and all other packages default to Base. The current setup is that every sig has exactly one production repo per CentOS version. Also, we seem to be wanting to see SIGs not as individual projects, but to make the 'G' an actual "group": so, for instance, the Virt SIG has both Xen and Docker, and we've recently approved oVirt. But there's a bit of a conflict here: what if one project in the SIG wants to use the package from Base, and another project in the SIG wants to use a custom-built package? Or what if both projects want to customize their packages in different ways? In particular: the Docker project in the Virt SIG wants to supply updated versions of Docker; but at the moment uses the kernel package from Base. The Xen project, on the other hand, needs to supply a different kernel package that has dom0 support enabled. Up until this point, this hasn't been an issue because I've been doing Xen development in virt6-testing, and Lokesh has been doing Docker development in virt7-testing. But I'm hoping to get Xen for CentOS 7 out soon, and I was just about to upload the Xen kernel to the CBS, when it occurred to me that if I did so, then everyone using the virt7-testing repo for Docker would suddenly get my updated kernel as well. So it seems we have a couple of ways to approach it. 1. Keep it one repo per SIG, and make all projects in a SIG sort out shared dependencies. 2. Allow one repo per *project* within a SIG (e.g., virt6-xen, virt7-docker) 3. Have some alternate way of doing a "patch", instead of repos. In the case of xen / docker, I haven't talked with Lokesh about this at all; it may be that he's fine with sharing a kernel with Xen. But it does increase the workload: now Lokesh needs to maintain the Docker side of the kernel, whereas before they could just rely on our upstream to do a lot of that testing. Furthermore, it increases the complexity of development and testing: before when doing kernel work, I could just test Xen; now the kernel needs to be tested by both Xen and Docker. And finally, now users of both projects get a kernel update whenever either one does. Which, of course, is pretty much the same as any other distro; but as a whole, at the moment at least, we have a lot less resources than any other distro our size and popularity. On the whole I'm inclined to prefer #2. Thoughts? -George

making distro evolving content available to CBS
by Karanbir Singh 10 Mar '15

10 Mar '15

hi, I'd like to see how we can get pre-release distro content into the cbs so that SIG's are able to start doing their thing and looking at / building / CI / release prep while the distro is shaping up. this content will need to come with the assumption that the rpms might need to be rebuilt, and none of them will be signed, and some of them will not see an EVR change as they are rebuilt. Within those constraints - what sort of a mechanism would work for : - the CBS team , to bring this content in - the SIGs - who want to consume some of this - the testing / CI team - to make sure these dont get - the CentOS QA team - who likely dont want to see bug reports filed against unreleased content ( in some cases, they actually might want to see problem reports, so they can help fix before release! ) and we just need to make sure we dont release anything built against this unsigned content. -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

Release for Atomic Host Feb 2015 rolling builds
by Karanbir Singh 10 Mar '15

10 Mar '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 We are pleased to announce CentOS Atomic host rolling builds for CentOS Linux. This release is tagged 20150228_01 : It represents content from Feb 2015 CentOS Linux 7 + Atomic SIG and Virtualisation SIG. A major change in this release is that all images are now built via anaconda and no longer consume the ostree-toolbox chain. This includes the generic cloud image ( qcow2 file ) and the Vagrant-VirtualBox and Vagrant-LibVirt ( .box ) files. The upstream ostree repo remains unchanged, including centos-release-atomic. Note that the Generic Cloud image ( qcow2 file ) still requires a NoCloud cloud-init configuration iso to enable access. The Vagrant images, do not. They will just work with the vagrant default access policy. - ----------- File: CentOS-7-x86_64-AtomicHost-20150228_01.qcow2 Sha256: ec94554d92558328e2ce7627996ce21faf76105be125d7f711615c1850956e0a File: CentOS-7-x86_64-AtomicHost-20150228_01.qcow2.xz Sha256: b366f73e4445e139a2df2bef935be863a377960714bdad22d5b47593d7ccec93 File: CentOS-7-x86_64-AtomicHost-Vagrant-LibVirt-20150228_01.box Sha256: fbf23af105258df88a85393dff2104348c7f4004562502a2b5711309eeaac473 File: CentOS-7-x86_64-AtomicHost-Vagrant-VirtualBox-20150228_01.box Sha256: 4dbeeba41dbf4d8f07047494399c7b0997bfde9fe049aba34f8f199e65c9e862 Symlinks are provided that will always map to the latest released builds, as follows ( including their current mapping ) http://buildlogs.centos.org/rolling/7/isos/x86_64/CentOS-7-x86_64-AtomicHos… - -> CentOS-7-x86_64-AtomicHost-20150228_01.qcow2 http://buildlogs.centos.org/rolling/7/isos/x86_64/CentOS-7-x86_64-AtomicHos… - -> CentOS-7-x86_64-AtomicHost-20150228_01.qcow2.xz http://buildlogs.centos.org/rolling/7/isos/x86_64/CentOS-7-x86_64-AtomicHos… - -> CentOS-7-x86_64-AtomicHost-Vagrant-LibVirt-20150228_01.box http://buildlogs.centos.org/rolling/7/isos/x86_64/CentOS-7-x86_64-AtomicHos… - -> CentOS-7-x86_64-AtomicHost-Vagrant-VirtualBox-20150228_01.box These symlinks will be updated to point at the latest tested and released media and make for a good target in automation that requires CentOS Linux media. - ---------- For more information and comments please join us on the centos-devel mailing list ( http://lists.centos.org/ ) Thanks to Colin Walters, Ian McLeod, Fabian Arrotin, Thomas Oulevey, Jason Brooks and Joe Brockmeier for their help in building up this process and their contributions to the Atomic SIG efforts.

Re: [CentOS-devel] ABRT in 7.1
by Matej Habrnal 10 Mar '15

10 Mar '15

Hi, I have created the upstream patches for abrt and libreport for ABRT in CentOS 7.1. Patch '0001-fix-patch-libreport-centos-branding-changes.patch-fo.patch' fot libreport fixes a patch 'libreport-centos-branding-changes.patch'. Libreport cannot be compiled with the old version of this patch. Patch '0002-reporter-mantisbt-introduce-reporter-mantisbt.patch' for libreport ships the mantis reporter, required library and workflows. Patch '0001-reporter-mantisbt-changes-related-to-reporter-mantis.patch' for abrt sets URL to retrace server. Also ships some minor fixes.

GSoC 2015 status, mentors, and a call for extra help
by Karsten Wade 09 Mar '15

09 Mar '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi: As many of you know, the CentOS Project was chosen as a mentoring organization for this year's Google Summer of Code. Yay! Some of you have been asked already to be mentors around specific projects, and Karanbir (mainly) and myself are talking 1:1 with those people to confirm you want to do it, answer concerns, etc. You can contact me directly with any questions you have. I want to open this discussion for a public chat about what mentoring entails, etc. We'll be populating the mentor/admin mailing list soon, and that's when we'll really dig in to the fundamentals of being a mentor as well as the administriva of the project. In addition, the student proposal creation and review process benefits from more mentors than will just work directly with students. If you have any interest in being involved in the GSoC but cannot or do not want to mentor a specific project, there are several ways we'd love your help: * Join the proposal review process, helping students craft good and sane proposals.[1] * Help vote on the final selection of students and projects. * Be a leader within the community especially during the students' initial "getting to know the community" phase (it lasts a few months before coding starts.) Regards, - - Karsten [1] Create a profile here, then make a connection to the project: https://www.google-melange.com/gsoc/homepage/google/gsoc2015 If you have any problems getting connected, email me your username in that system and I'll make the connection from the admin side. - -- Karsten 'quaid' Wade .^\ CentOS Doer of Stuff http://TheOpenSourceWay.org \ http://community.redhat.com @quaid (identi.ca/twitter/IRC) \v' gpg: AD0E0C41 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iEYEARECAAYFAlT+AyAACgkQ2ZIOBq0ODEEqwgCgkbDeZ9K5bh7HFpKYdN1JVKj7 OC8An1zmtfUI6LGB+J4M3whgiPq5FMvW =Wpyk -----END PGP SIGNATURE-----

4 week Atomic Releases?
by Michael P. McGrath 09 Mar '15

09 Mar '15

In conjunction with this Fedora Atomic thread: https://lists.fedoraproject.org/pipermail/cloud/2015-March/004976.html I'd like to continue discussion about CentOS Atomic and a move to a 4 week release cycle. I'm specifically targeting CentOS Atomic here, and as it turns out we are very close to doing this today with a new Atomic build being targeted roughly every Month by Ian. In the larger ecosystem, the development versions released in Fedora would be tested there for a bit and then drawn down to the CentOS Atomic image and released. We think we can move a bit faster in Atomic because of it's simple rollback function. Since the CentOS Atomic images are already so close to what is being proposed, this is likely to be a formalization of what is being done and better highlighting of the CentOS Atomic image on the projectatomic.io website. Any thoughts or comments? -- Mike McGrath | mmcgrath(a)redhat.com | (312) 660-3547 Atomic | Red Hat Chicago | http://projectatomic.io/
