RFC: Performance tuning of the Vagrant images
by Laurentiu Pancescu 28 Apr '16

28 Apr '16

Hello everyone, I would like to ask for your feedback about tuning the official CentOS images for Vagrant. The good news: the next release will probably provide Vagrant images for both CentOS 6 and 7, not just 7 as until now. Deltarpm allows yum to download just binary diffs for the already installed packages and rebuild the rpms locally, thus decreasing the used bandwidth. However, this is quite CPU and I/O intensive, and significantly slower than just downloading the full packages (at least for users on any sort of broadband connection). Deltarpm can be useful for users in development countries, which do not always have access to unmetered broadband, while someone hosting many VM instances on the same server, like a VPS provider, might want to avoid the extra I/O load (especially on mechanical hard-disks). Deltarpm is already part of the CentOS 7 images since May 2015 - should we keep it or remove it? Tuned, a daemon that can adjust system parameters based on the workload (it comes with a number of profiles, optimized for different situations), is preinstalled in CentOS 7, and can significantly improve performance and/or reduce load. Tuned can also be installed in CentOS 6, and it would increase the size of the Vagrant image with just 291kB, since its prerequisites are already installed. Should we add it to CentOS 6? If you are not familiar with tuned, the following links might be helpful: http://servicesblog.redhat.com/2012/04/16/tuning-your-system-with-tuned/ http://www.slideshare.net/IamFedora/tuned Thanks in advance, Laurențiu

[Infra] : DevCloud maintenance window notification
by Fabian Arrotin 26 Apr '16

26 Apr '16

Due to recent changes in the racks hosting the DevCloud nodes (https://wiki.centos.org/DevCloud), we'll have to reorganize the physical placement of those nodes. That means that we'll have to shut down/power off the whole DevCloud infra, migrate the nodes in another rack, and slowly restart all the services running on those nodes. Important notice : if you are a CentOS contributor/developer having some Virtual Machines in DevCloud, ensure that everything is correctly setup on your side, as we'll only (from an hypervisor PoV) issue acpi shutdown to the VMs Other impacted services: - http://planet.centos.org - http://seven.centos.org - http://armv7.dev.centos.org (plague-server, so no armhfp build during that maintenance window) Migration is scheduled for """"Tuesday April 26th, 2:30 pm UTC time"""". You can convert to local time with $(date -d '2016-04-26 14:30 UTC') We'll slowly restart services when possible and we expect everything to be back online before 8:00 pm UTC. Thanks for your comprehending and patience. on behalf of the Infra team, -- Fabian Arrotin The CentOS Project | http://www.centos.org gpg key: 56BEC54E | twitter: @arrfab

Getting started with CentOS Community Container Pipeline on Vagrant
by Ratnadeep Debnath 25 Apr '16

25 Apr '16

Hi all, We have come up with scripts[1] to deploy CentOS Community Container Pipeline(CCCP, in short). A typical CCCP setup comprises of 3 nodes: Jenkins master, Jenkins slave, Openshift server. To ease the setup of this multi node environment, we have created a Vagrantfile[2] to get you started with your CCCP setup in no time. Special thanks to Dharmit Shah and Praveen Kumar to help me out with testing and improving these deployment scripts. Below is the set of instructions to get you started with CCCP. You can also find the latest and updated set of instructions here[3]. Setup ===== sudo yum install -y epel-release git # We are installing Ansible from pip because there's a bug in Ansible Docker module in EPEL sudo yum install -y python-pip sudo pip install ansible sudo yum install centos-release-scl qemu-kvm libvirt sudo yum -y install sclo-vagrant1 sudo yum install python2-jenkins-job-builder # start libvirtd sudo systemctl start libvirtd; sudo systemctl enable libvirtd # enable bash on vagrant scl sudo scl enable sclo-vagrant1 bash Deploy ===== git clone https://github.com/rtnpro/centos-cccp-ansible cd centos-cccp-ansible vagrant plugin install vagrant-hostmanager vagrant up --no-provision vagrant provision Configure Jenkins Job Builder ====================== Create file /etc/jenkins_jobs/jenkins_jobs.ini with content similar to: [jenkins] user=admin password=admin url=http://cccp-master.example.com:8080/ Push jobs to jenkins =============== Clone the repos in the same directory: git clone https://github.com/bamachrn/cccp-service.git git clone https://github.com/kbsingh/cccp-index.git Then do: cd cccp-service/jenkinsbuilder python cccp_index_reader.py ../../cccp-index/index.yml And wait for the jobs for the projects in the index to be pushed to Jenkins.

New Mock for testing on CentOS-7
by Johnny Hughes 21 Apr '16

21 Apr '16

There is a new mock rpm for testing here: http://cbs.centos.org/repos/core7-extras-common-testing/x86_64/os/Packages/ mock-*1.2.17-1.el7.centos.noarch.rpm This mock has centos-<ver>-<arch>.cfg files that should work for building against all the released trees for CentOS-7 (x86_64, i686, ppc64, ppc64le,aarch64,armhfp), CentOS-6 (i686,x86_64), and CentOS-5 (i686,x86_64). If these mock configs work, we will try to get them rolled in upstream in EPEL. Please report any issues on this list. Thanks, Johnny Hughes

CentOS SCLo SIG sync-up meeting (2016-04-20)
by Honza Horak 21 Apr '16

21 Apr '16

The meeting will be at 16:00 UTC (12:00 EST, 18:00 Brno, 12:00 Boston, 1:00+1d Tokyo, 2:00+1d Brisbane) in #centos-devel on Freenode. No specific agenda for today, but will be available today for discussion if necessary. Except that, I'd like to look for a new timeslot for the meeting, we moved it one hour late after few conflicts we found with other SIGs and it does not fit to my schedule much any more. Honza
