Update on CentOS Community Container Pipeline
by Bamacharan Kundu 10 May '17

10 May '17

Hi, Below is an update on recent works for CentOS Community Container Pipeline * Now emails from prod and test are distinguished, by prepending test to subject for emails from test. * Filters are added for scanner rpm verify for centos base image issues. * Changed email notification for the user to address the image name properly. * Issues with linter are fixed now to make sure it does not point registry.centos.org as invalid registry. * Configurable logrotate policy is added to make sure worker logs are handled properly. * For every deployment, fresh images are now pulled for container-pipeline dependency images. Our current focus is on: * Get test_worker and internal registry working with build streamline. * Make Dockerfile lint trigger work with Mail worker to send an email if Dockerfile is not present at git_path. * Fix issues with weekly scan mail to point to proper logs * Fix errors coming for services when they are not able to communicate to beanstalk * Work on email module to be able to receive send email request from all other module * Logging - Storing logs per build and also having shadow rotating logfile where all logs are streamlined We are working to get the below projects in registry.centos.org * sentry * ScyllaDB (https://groups.google.com/forum/#!topic/scylladb-dev/T2rIeqjac14) * MonetDB * Review board Regards Bama Charan Kundu

Vagrant images for Hyper-V

I'm late to joining this discussion but I'm happy to help. I work on the Hyper-V team and have been doing some testing and improvements to Vagrant and Packer on the side. re: sparse files - NTFS doesn't support sparse files, but Hyper-V does have dynamically expanding VHD and VHDX files. VHDX allocations are configurable but the default of 32MB is tuned to NTFS which puts all metadata at the beginning of the disk. Dropping VHDX allocations down to 1MB helps reduce the slack space left after each inode. VHD uses smaller allocations so it’s less of an issue. Both images are just over a gig on disk which is about what I’d expect. If you’re optimizing the template Vagrantfiles in the boxes, it would be very helpful to add differencing_disk = true to avoid copying the full VHD and reduce IO in vagrant up. Here's what I observed on each image Centos 6.1.1 - Vagrant didn't find an IP address upon bootup. I logged in via the console and the Hyper-V virtual NIC was on eth1 which didn't have dhclient configured. I ran dhclient manually, then vagrant ssh was able to find the IP Centos 7.1.1 - Vagrant worked as expected. It found the IP as the VM booted up. I haven't fully tested everything but wanted to share some of the results. Let me know if there's a list of tests run against the other boxes and I can go through them.

We need a newer Vagrant in SCL
by Laurentiu Pancescu 02 May '17

02 May '17

Hello, Our cico test for testing our Vagrant images have support for optionally using vagrant-vbguest. This is now failing with: + scl enable sclo-vagrant1 'vagrant plugin install vagrant-vbguest' Installing the 'vagrant-vbguest' plugin. This can take a few minutes... Bundler, the underlying system Vagrant uses to install plugins, reported an error. The error is shown below. These errors are usually caused by misconfigured plugin installations or transient network issues. The error from Bundler is: Authentication is required for http://gems.hashicorp.com/. Please supply credentials for this source. You can do this by running: bundle config http://gems.hashicorp.com/ username:password Build step 'Execute shell' marked build as failure I think this is caused by the older version we have in SCL - I can install vagrant-vbguest without any issues on Vagrant 1.9.3 (on OS X). I now reverted the test to not use vagrant-vbguest, but it's still failing because SCL Vagrant doesn't support VirtualBox 5.1.x. Oracle already put a warning on the download page for VirtualBox 5.0.x: "VirtualBox 5.0.x runs out of support, switch to VirtualBox 5.1.x!" https://www.virtualbox.org/wiki/Download_Old_Builds_5_0 We risk becoming unable to automatically test our images with VirtualBox - could we get a Vagrant update in SCL, please? Thanks, Laurentiu

SIG Proposal - High performance computing (HPC) SIG
by Ondřej Vašík 01 May '17

01 May '17

Hi, I would like to propose start of High performance computing (HPC) SIG. I see it already mentioned on https://wiki.centos.org/SpecialInterestGroup among Future SIGs. Primary reason for the SIG existence will be to improve the state of High performance computing related packages on CentOS and similar distributions, with special focus on stability of builds, CentOS (and similar distribution) related improvements for OpenHPC project and getting new HPC packages packaged for CentOS and/or Fedora. Initial members would be me (ovasik(a)redhat.com, CentOS FAS account: Reset), Adrian Reber (areber(a)redhat.com, CentOS FAS account: areber), Stanislav Kozina (skozina(a)redhat.com, CentOS FAS account: ersin) and Jan Chaloupka (jchaloup(a)fedoraproject.org, CentOS FAS account: jchaloup). Of course, anyone is welcome to join. Thanks in advance for approving/sponsoring the SIG. Regards, Ondrej Vasik
