CentOS docker testing image
by Karanbir Singh 04 Apr '14

04 Apr '14

hi, I've just pushed to cloud.centos.org a test build for a CentOS-6-x86_64 docker image. Please test and provide feedback. The image is hosted at http://cloud.centos.org/centos/6/devel/ and is called : CentOS-6.5-x86_64-GA-docker_01.img.tar.bz2 sha256sum for this file: dab02fd8eafa80995830d0bacdf6a7ae6bcad8cd94af6f71c747dc861ebb77d9 ---- Known Issues: * Need to run rpm --rebuilddb inside the container once, otherwise yum is largely non functional. * There seem to be some selinux issues ( afaict, leaving libselinux intact would fix that ) ---- Using this image: (with epel enabled, on your CentOS-6.5/x86_64 host ): # yum install docker-io # /sbin/service docker start # docker import http://cloud.centos.org/centos/6/devel/CentOS-6.5-x86_64-GA-docker_01.img.t… c65_x64 test1 # docker images ( you should see the image listed ) # docker run -t -i <image id> /bin/bash ( you should now be inside the container ) bash-4.1# rpm --rebuilddb ---- Contributing changes: please send pull requests via: https://github.com/CentOS/sig-cloud-instance-build regards, -- Karanbir Singh, Project Lead, The CentOS Project +44-207-0999389 | http://www.centos.org/ | twitter.com/CentOS GnuPG Key : http://www.karan.org/publickey.asc

Recompiling the Kernel for CentOS 6.5
by Saket Sinha 28 Mar '14

28 Mar '14

Hi, I am working on CentOS 6.5 which has 2.6.32-431 kernel. I have a problem with my driver and I need to enable Kernel-Memory leak in the kernel for which I will have to recompile the kernel. I get the kernel source tree from the the source rpm for my running kernel from below link- http://vault.centos.org/6.5/updates/Source/SPackages/kernel-2.6.32-431.11.2… and I try to build the kernel according to the below link on CentOS Wiki - http://www.centos.org/docs/rhel-sag-en-3/s1-custom-kernel-modularized.html according to which it tells me , after make menuconfig( and customizing my configuration), I need to follow the following steps- 1. make bzImage 2. make modules 3. make modules_install 4. make install but I get errors in the first step only-(make bzImage) Kindly suggest me as to what I am doing wrong. Regards, Saket SInha

Fwd: Announcing: Data Liberate, a Storage Hackathon and Mixer - Sunday, April 13, SF
by John Mark Walker 24 Mar '14

24 Mar '14

Forwarding this here - we'd like to get some CentOS storage SIG packaging done. Free lunch and happy hour drinks will be served on-site. -JM ----- Forwarded Message ----- From: "John Mark Walker" <johnmark(a)gluster.org> To: "Gluster Devel" <gluster-devel(a)nongnu.org> Sent: Monday, March 24, 2014 12:01:37 PM Greetings, Red Hat Storage is sponsoring Data Liberate: a Storage Hackathon and Mixer in San Francisco on Sunday, April 13. Would be great to get general participation from people in the area, as well as some hacking on big data, cloud and virtualization management integration. RSVP at http://dataliberate.eventbrite.com/ If you're interested in sponsoring, contact me off-list. Description: Hack all day, stay for the prizes and party! Modern cloud workloads demand storage services that are easily consumable and available to a variety of platforms. We need to liberate our data from the shackles of the big, dumb (proprietary) storage box and move it into the 21st century. So come one, come all storage, cloud and big data developers and devops practitioners. The Data Liberate Hackathon will be a chance for developers in disparate worlds to link their applications, infrastructure and other code with storage services. And did I mention fabulous prizes? And drinks? _______________________________________________ Gluster-devel mailing list Gluster-devel(a)nongnu.org https://lists.nongnu.org/mailman/listinfo/gluster-devel

Re: [CentOS-devel] CentOS Firewall and UTM SIG
by Shafiee Roozbeh 21 Mar '14

21 Mar '14

@eduardo Yes you are right. You are not crazy dreamer ! A midrange UTM and uper should support this features and another... The technical topic will open later, for now we are talking about general subjects ! Are goal is CentOS Security SIG ! A version of CentOS that provide features for network security and my topics to discuss are: - Do we need this SIG in CentOS ecosystem? - Is it any parallel project in CentOS right now? - Is CentOS a suitable base to provide and create this project? - and anything you think... :-) On Mar 22, 2014 3:15 AM, "Eduardo Kaftanski" <ekaftan(a)gmail.com> wrote: Can I elaborate a bit on what I would like this SIG to provide? -An integrated web console for object oriented (objects being servers, pc-workstations and people) network access manager. This console would get installed in a centralized server (maybe a small VM on whatever virtualization system you have) -A small dedicated CentOS server that you can install over comodity hardware. This would be an 'almost zero config' server. You only need to specify the IP for the admin interface and the IP for the central admin-server -This small servers can act as firewalls, mail proxys, antiviruses, web proxies, DNS, etc. -Small network? One small VM for the adminserver + one box doing firewall, proxy, mx, snort, etc. -Growing up? install a second box. Select proxy off for box 1 on the admin console, select proxy on on the second box. Select 'transparent on'. Select antivirus on. Click apply. Box one is no longer your proxy but transparently redirects proxy traffic to box two, now your proxy. yes, I am a crazy dreamer, but its like Asterisk... if you want a very small cheap PBX you can buy a Panasonic for US$500. You need Asterisk when you want the strange and crazy features. you dont install a CentOS firewall for a tiny network. A small WRT box works better is more stable and its way cheaper. You need a CentOS box when you are doing strange things, like balancinh, HA, multiview DNS, multiple ISP links, openvpn servers, ipsec, etc.. Ah... at least down here customers place MUCH more weight on the ability to selectively block access to their own people than protecting from outside attacks and 90% of the configurations I make have no external access at all. All they care is to be able to allow and block youtube and facebook with a mouse click.

how minimal is a minimal too minimal
by Karanbir Singh 20 Mar '14

20 Mar '14

Hi Something that keeps coming up is how far can we minimalise an Instance / Image / Installer before we cant call it CentOS anymore. In the past, what we have generally stuck with is: - CentOS Shipped kernel - Initscripts - functional yum - functional openssh-server - atleast all of @base however, in some cases, openssh-server might not be needed, and initscripts has a fairly long dep tree, similarly making yum work needs a few things. Can we get away with losing yum as an example and replacing it with a script that says 'need yum? I can download and install it for you' and have it hit mirror.centos.org for static yum and yum dep urls ? similarly, should nobase and nocore be acceptable ? the aim being to setup a base image, that is under 150mb to download and deploy. -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

Board Meeting Today
by Karanbir Singh 20 Mar '14

20 Mar '14

hi Guys, I need to get a more elegant way to map time, task and board meetings - but we have made some headway in getting minutes and content from past meetings online on the website. Also, every other meeting is now held publicly on a google hangout with the recorded session being made available immediately after. Todays meeting is going to consider SIG proposals for - Storage SIG http://wiki.centos.org/SpecialInterestGroup/Storage/Proposal - Cloud Instance SIG http://wiki.centos.org/SpecialInterestGroup/CloudInstance/Proposal & http://wiki.centos.org/SpecialInterestGroup/CloudInstance I request everyone who is interested in being a part of this process come join us on #centos-devel irc.freenode.net at 21:00 UTC today, 19th Mar 2014. -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

CentOS Docker images
by Chris St. Pierre 19 Mar '14

19 Mar '14

I've volunteered to help maintain official CentOS Docker ( https://www.docker.io/) images, and Karanbir suggested I email the list to "thrash out what we need at the infra end to achieve these images." Currently, there are 'centos' images available in the top-level Docker registry namespace, but these are maintained by dotcloud. I think we can do better. :) As I see it, there are two ways we can do this: 1. Use ami-creator (https://github.com/katzj/ami-creator) or something derived from it, to build Docker images from a kickstart file. This is how CentOS AMIs are currently built. Pros: Consistent with how AMIs are usually built; Kickstart is a known entity. Cons: ami-creator won't actually work for us as-is; requires a full kickstart config. 2. Use the mkimage-yum.sh script from Docker ( https://github.com/dotcloud/docker/blob/master/contrib/mkimage-yum.sh) customized as necessary to produce a minimal base image. Pros: Consistent with how Docker images are usually built; we can contribute changes to mkimage-yum.sh upstream to help other Yum-based distros; only requires a yum config. Cons: Requires changing a shell script to make changes to the base image, not just a Kickstart. Unfortunately, Docker Trusted Build ( http://blog.docker.io/2013/11/introducing-trusted-builds/) can't be used for base images, AFAICT. In either case, we'll need a git repo to hold the code and configs used to build the images. If we follow the example of the official CentOS AMIs ( http://wiki.centos.org/Cloud/AWS) it should be sufficient to provide a reasonably up-to-date base image ("latest" or "nightly" or similar), and a few recent dot releases. Of course, once CentOS 7 is released we'll need to do that for both 6 and 7, but that shouldn't be difficult if we do this right. Thoughts on process and/or infrastructure? -- Chris St. Pierre
