SIG Updates

SIGs - Special Interest Groups - are where people work on the stuff that runs on top of CentOS.

Several of our SIGs published their quarterly reports this month:

Next month we hope to hear from:

  • Artwork
  • Cloud Instance
  • OpsTools
  • Public CI
  • Virtualization

Events

We started off February with a bang, with our annual CentOS Dojo at FOSDEM.  You can read a summary of that event on the CentOS blog. We will be posting video from the event on the CentOS YouTube channel as soon as possible.

We also had a table at FOSDEM itself. FOSDEM is a gathering of 6000 free/open source software enthusiasts at Brussel's ULB. Topics covered are everything from distributions to licensing to community to storage. Video from almost every session at the event is already available at the event website.

Next month, we expect to have a presence at FOSSAsia in Singapore.

And in April we are planning to hold a Dojo at Oak Ridge National Labs, in Oak Ridge Tennessee.

If you would like to host a Dojo, or have a suggestion for where we should have one, please get in touch with the CentOS Promo mailing list.

Other upcoming events are always listed on the events wiki page.

On Friday of last week, we once again gathered in Brussels for our annual CentOS Dojo at FOSDEM.

14 speakers gave talks on a wide variety of topics, ranging from deeply technical, to community-centered, to a vision of what's coming in CentOS 8. The full schedule is on the event website, and the videos from the event will be posted on YouTube as soon as we can possibly get them up.

We had roughly 90 people in attendance at this event, which was about the same as last year.

At lunch time, we celebrated CentOS's 15th birthday with a lovely birthday cake.

(More pictures here.)

If you missed us in Brussels, don't worry. We have lots of other events coming up.

If you would like to host a Dojo, or have a suggestion of where we should run on, please don't hesitate to get in touch with us on the CentOS-Promo mailing list.

We are pleased to announce new official Vagrant images of CentOS Linux 6.10 and CentOS Linux 7.6.1810 for x86_64. All included packages have been updated to January 28th, 2019.

Known Issues

  1. The VirtualBox Guest Additions are not preinstalled; if you need them for shared folders, please install the vagrant-vbguest plugin and add the following line to your Vagrantfile:
    config.vm.synced_folder ".", "/vagrant", type: "virtualbox"

    We recommend using NFS instead of VirtualBox shared folders if possible; you can also use the vagrant-sshfs plugin, which, unlike NFS, works on all operating systems.

  2. Since the Guest Additions are missing, our images are preconfigured to use rsync for synced folders. Windows users can either use SMB for synced folders, or disable the sync directory by adding the line
    config.vm.synced_folder ".", "/vagrant", disabled: true

    to their Vagrantfile, to prevent errors on "vagrant up".

  3. Installing open-vm-tools is not enough for enabling shared folders with Vagrant’s VMware provider. Please follow the detailed instructions in https://github.com/mvermaes/centos-vmware-tools
  4. Some people reported "could not resolve host" errors when running the centos/7 image for VirtualBox on Windows hosts. We don't have access to any Windows computer, but some people reported that adding the following line to the Vagrantfile fixed the problem:
    vb.customize ["modifyvm", :id, "--natdnshostresolver1", "off"]

Recommended Setup on the Host

Our automatic testing is running on a CentOS Linux 7 host, using Vagrant 1.9.4 with vagrant-libvirt and VirtualBox 5.1.20 (without the Guest Additions) as providers. We strongly recommend using the libvirt provider when stability is required.

Downloads

The official images can be downloaded from Vagrant Cloud. We provide images for HyperV, libvirt-kvm, VirtualBox and VMware.

If you never used our images before:

vagrant box add centos/6 # for CentOS Linux 6, or...
vagrant box add centos/7 # for CentOS Linux 7

Existing users can upgrade their images:

vagrant box update --box centos/6
vagrant box update --box centos/7

Verifying the integrity of the images

The SHA256 checksums of the images are signed with the CentOS 7 Official Signing Key. First, download and verify the checksum file:

$ curl http://cloud.centos.org/centos/7/vagrant/x86_64/images/sha256sum.txt.asc -o sha256sum.txt.asc
$ gpg --verify sha256sum.txt.asc

Once you are sure that the checksums are properly signed by the CentOS Project, you have to include them in your Vagrantfile (Vagrant unfortunately ignores the checksum provided from the command line). Here's the relevant snippet from my own Vagrantfile, using v1803.01 and VirtualBox:

Vagrant.configure(2) do |config|
  config.vm.box = "centos/7"

  config.vm.provider :virtualbox do |virtualbox, override|
    virtualbox.memory = 1024
    override.vm.box_download_checksum_type = "sha256"
    override.vm.box_download_checksum = "b24c912b136d2aa9b7b94fc2689b2001c8d04280cf25983123e45b6a52693fb3"
    override.vm.box_url = "https://cloud.centos.org/centos/7/vagrant/x86_64/images/CentOS-7-x86_64-Vagrant-1803_01.VirtualBox.box"
  end
end

Feedback

If you encounter any unexpected issues with the Vagrant images, feel free to ask on the centos-devel mailing list, or in #centos on Freenode IRC.

Ackowledgements

I would like to warmly thank Brian Stinson, Fabian Arrotin and Thomas Oulevey for their work on the build infrastructure, as well as Patrick Lang from Microsoft for testing and feedback on the Hyper-V images. I would also like to thank the CentOS Project Lead, Karanbir Singh, without whose years of continuous support we wouldn't have had the Vagrant images in their present form.

I would also like to thank the following people (in alphabetical order):

  • Graham Mainwaring, for helping with tests and validations;
  • Michael Vermaes, for testing our official images, as well as for writing the detailed guide to using them with VMware Fusion Pro and VMware Workstation Pro;
  • Kirill Kalachev, for reporting and debugging the host name errors with VirtualBox on Windows hosts.

NFV SIG Quarterly Report through February 1st, 2019

Purpose

The CentOS NFV  SIG exists to support Network Function Virtualization (NFV) in CentOS. Specifically, the idea is to be a vehicle to provide packages for implementers of software networks on the CentOS platform.

Membership Update

In this reporting period, we have had little formal participation. However, there has been continued in NFV on CentOS and interest in deploying our packages on CentOS. We are always looking for additional community participation in all aspects of this SIG, including promoting, building releasing other packages for NFV.

Anyone interested in participating in the NFV SIG should subscribe to the generic CentOS mailing list.

Releases and Packages

fd.io VPP

The past quarter has been a slow one in terms of actual delivered packages. Our main active package, VPP has not been released since 1807. Upstream version 1810 requires dev-toolset 7.

However, recently dev-toolset-7 and all prerequisites have been built and-or cross tagged into the NFV SIG common. We are currently in the process of building vpp 19.01 for release and plan to have these packages ready in February.

To install latest release of VPP,

yum install centos-release-fdio

yum install vpp*

Health and Activity

The health of NFV SIG could be better. It was originally perceived as the sponsor for getting OPNFV project into the CentOS distribution. However, subsequently OPNFV releases its own CD images. Subsequently it was primarily sponsoring building opendaylight packages which are still built as part of the upstream product CI.

Since Q1 2018 the project has been focused on building packages and dependencies for upstream fast data plane project, fd.io

including vpp.

At this point, the project is looking for a renewed focus. Perhaps, packages to facilitate containerization and kubernetes. Other ideas and sponsors are welcome.

Also, we have also been working towards several upcoming events.

On February 1st, we will have a presentation about NFV SIG at  CentOS Dojo at FOSDEM, in Brussels.

Issues for the Board

We have no issues to bring to the board’s attention at this time.

 

As per the SIG reporting guide, the Promo SIG offers its quarterly report for the period from Nov 1, 2018 through Feb 1, 2019

Purpose

The CentOS Promotion SIG exists to provide promotion, and consistent messaging, of CentOS, both at physical events and online.

Membership Update

In the reporting period, we have had participation from a handful of people. We are always looking for additional community participation in all aspects of this SIG, including, but not limited to, helping out at events.

Anyone interested in participating in the Promo SIG should subscribe to the mailing list.

Activity

The past quarter has been a slow one in terms of actual event participation.

We had a presence at the Supercomputing event SC18 in Dallas, Texas, where Rich Bowen interviewed some of the student cluster competition teams. Those videos may be seen on the CentOS YouTube channel.

We have also been working towards several upcoming events.

On February 1st, we will be holding the annual CentOS Dojo at FOSDEM, in Brussels. At the time of this writing, we have 125 people registered for the event. A followup event report will be posted here in the next 2 weeks.

In April, we are planning to hold a Dojo at ORNL, in Oak Ridge, Tennessee, USA. The schedule is coming together and we should be announcing more details immediately after FOSDEM.

Later in 2019, we plan to hold dojos at DevConf.US, and DevConf.IN. No details are available for either of these events, but should be announced in the next month.

Each month we publish the community newsletter. These may be read on this blog, and are listed in the wiki.

We are planning various things around the upcoming 15th anniversary of the CentOS project, including birthday cakes at various of our Dojos, and a series of interviews with people who have been around the project for many years. We hope to record some of these interviews at FOSDEM, and others both online, and at upcoming events during the year. If you would like to be interviewed, please contact Rich on the promo mailing list.

This has been a slow quarter for social media, as November and December often are. However, we continue to post content to Twitter, Facebook, LinkedIn, and Reddit. With the announced retirement of Google+, we have discontinued posting content there.

Purpose

The CentOS PaaS SIG is working on delivering multiple PaaS Stacks that are built, tested and delivered into the CentOS Ecosystem for end user consumption, run as a service and also provided in various formats ( rpms, containers, images etc ) for other efforts in the CentOS Ecosystem, that can derive value from this content.

Releases and Packages

OKD 3.11 has released in this quarter and we keep working on maintaining the packages while the updates are coming from the main repository. We provide also the openshift-ansible package containing all playbooks to deploy OKD on CentOS environments.

To install openshift-ansible package, run the command:

yum install openshift-ansible

Biweekly meetings

The SIG decided to host biweekly meetings due to low traffic of information. We invite everyone to join the meeting and ask for help, improvements, and collaboration. Our meeting is biweeklyWednesdays at 17:00 UTC. You can check your timezone time with the command:

date -d "1700 UTC"

We are pleased to announce new official Vagrant images of CentOS Linux 6.10 and CentOS Linux 7.6.1810 for x86_64. All included packages have been updated to January 1st, 2019.

Important changes

The centos/7 images use the XFS filesystem again (we had to temporarily switch to ext4 due to filesystem corruption involving qemu and XFS in 7.5.1804).

Known Issues

  1. The VirtualBox Guest Additions are not preinstalled; if you need them for shared folders, please install the vagrant-vbguest plugin and add the following line to your Vagrantfile:

CentOS SCLo SIG Quarterly report

Purpose

Packaging and maintaining Software Collections packages,
providing the ability to install several versions of various software side by side.

Releases and packages

Several new software collections were provided:

Some older software collections were retired due to their upstream End-of-Life status.
If a collection you depend on vanished from the repositories,
it is advised to upgrade to a newer variant of that collection as soon as possible.
As a last resort, the retired and unsupported packages can be found at CentOS vault.
