Dear CentOS enthusiast,

Another month into 2019, and we have a lot to tell you about.

#CentOS15

Yes, we've mentioned this before, but we're still pretty stoked about it. On the 15th, we celebrated our 15th birthday with a small group of friends in Oak Ridge, Tennessee, before our Dojo at Oak Ridge National Laboratories. You can see some of the videos from that event beginning to appear on our YouTube channel.

If you would like to talk about your involvement in CentOS, please get in touch with Rich at rbowen@centosproject.org  You don't need to be one of the founders - just to have something interesting to say about your involvement, past, present, and future.

git.centos.org changes

As we mentioned last month, there have been some significant changes to git.centos.org. The service was upgraded/migrated to Pagure. You can read details about the change, and instructions on using the new service on the mailing list archive. And further documentation is now in the wiki, at https://wiki.centos.org/Sources

If you have any questions or difficulties using the new service, please drop by either the centos-devel mailing list, or the #centos-devel IRC channel on Freenode.

 

Releases and updates

We had another moderately busy month for update and releases.

Errata and Enhancements Advisories

We issued the following CEEA (CentOS Errata and Enhancements Advisories) during April:

Errata and Security Advisories

We issued the following CESA (CentOS Errata and Security Advisories) during April:

Errata and Bugfix Advisories

We issued the following CEBA (CentOS Errata and Bugfix Advisories) during April:

SIG Updates

SIGs - Special Interest Groups - are where people work on the stuff that runs on top of CentOS. We have recently started having SIGs report quarterly, so we have just a few of them each month, getting through the entire list every 3 months.

We have the following SIG reports this month:

NFV SIG

The NFV SIG posted their report to the CentOS blog.

Storage SIG

This is by no means a complete report but here are a few "juicy" notes
hopefully worth sharing!

Starting in May we'll have a new member in the Storage SIG: Francesco
Pantano, he'll start helping us with the maintenance of the
Ceph/ceph-ansible builds (and their deps).

We have in fact finally populated our Ceph Nautilus repo with a initial
Ceph Nautilus build and we also included RC builds of ceph-ansible;
please help us test both Ceph and the deployment tool itself enabling
the SIG repos by installing the new centos-release-ceph-nautilus package.

We're looking for help with the new builds test automation; ideally we'd
like to have automatic promotion into -release repos of the new builds
when these pass testing; if you can or are interested in helping us with
this effort please get in touch!

See you online.

Cloud SIG

Purpose
Packaging and maintaining different FOSS based Private cloud infrastructure applications that one can install and run natively on CentOS.
Membership Update
We are always looking for new members, especially representation from cloud technologies other than RDO.
Releases and PackagesRDO
April 8 - 12 OpenStack Stein Released https://blogs.rdoproject.org/2019/04/rdo-stein-released/
Interesting things in the Stein release include:
- Ceph Nautilus is the default version of Ceph, a free-software storage platform, implements object storage on a single distributed computer cluster, and provides interfaces for object-, block- and file-level storage, within RDO (or is it the default without OpenStack?).  Within Nautilus, the Ceph Dashboard has gained a lot of new functionality like support for multiple users / roles, SSO (SAMLv2) for user authentication, auditing support, a new landing page showing more metrics and health info, I18N support, and REST API documentation with Swagger API.
- The extracted Placement service, used to track cloud resource inventories and usages to help other services effectively manage and allocate their resources, is now packaged as part of RDO. Placement has added the ability to target a candidate resource provider, easing specifying a host for workload migration, increased API performance by 50% for common scheduling operations, and simplified the code by removing unneeded complexity, easing future maintenance.
Other improvements include:
- The TripleO deployment service, used to develop and maintain tooling and infrastructure able to deploy OpenStack in production, using OpenStack itself wherever possible, added support for podman and buildah for containers and container images. Open Virtual Network (OVN) is now the default network configuration and TripleO now has improved composable network support for creating L3 routed networks and IPV6 network support.
  •  April 28 - May 1 OpenInfrastructure Summit Denver Colorado USA
  • May 2 - 4 Train Release Project Team Gathering Denver Colorado USA
  • June 3 - 7 Train Milestone 1
  • June 13 - 14 RDO Test Days Train Milestone 1
Health and Activity
The Cloud SIG remains fairly healthy. However, it is still, for the most part, a monoculture containing only OpenStack.
Issues for the Board
We have no issues to bring to the board’s attention at this time.

As always, a big thank you to our SIGs, for the work that they do, and for the time taken to check back in with these status reports!

Events

In April, as mentioned above, we ran a CentOS Dojo at ORNL - Oak Ridge National Labs. The presentation slides are starting to get added to  the event website. We expect to have the full video from the event within the next week or two.

I'm writing this newsletter from the  Open Infrastructure Summit (formerly known as OpenStack Summit), in Denver. We joined our friends from RDO and Ceph, as well as our colleagues from Red Hat, to discuss all aspects of open infrastructure, especially OpenStack.

A high point included the gathering of some of the largest open science clusters on the planet, running their OpenStack/RDO clouds on CentOS

And, coming up, we're planning to run a CentOS Dojo in Boston, on the day before DevConf.US. The call for presentations is open, and we want to hear from you! Talks about anything you're doing in, on, or around CentOS is fair game. Submit your talks HERE.

NFV SIG Quarterly Report through May 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 somewhat slow one in terms of actual delivered packages.

However, we did release vpp 19.01.

The outlook for vpp 19.04 and 19.08 is TBD at this point.

DPDK

There has been some renewed interest in dpdk packaging. At this point, there is no immediate plans to release recent DPDK in NFV SIG.

We would welcome a sponsor to work with the NFV SIG upstream community to bring recent dpdk packages into CentOS NFV SIG.

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

In April, vpp 1901 has been released to mirrors and is currently available in build-logs.

At this point, the NFV SIG is continuing to look for a renewed focus. In particular, we are looking for packages to facilitate containerization and kubernetes. Other ideas and sponsors are welcome.

Issues for the Board

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

Today, CentOS turns 15 years old. It’s had hard times and good times, and gone through a number of big changes over those years. We feel that we’ve landed in a really great place, over the last 5 years, as part of the Red Hat family of projects, and we’re very excited about what’s coming with CentOS 8, and the years to come.

Right now, we want to look back at how we got where we are now. We did that by going back and talking with some of the people that were involved in those early years, as well as some that joined the project later on.

We started by talking with Greg Kurtzer, who was the original founder of the project. In this interview, he told us about the motivations for starting the project, as well as some of the community challenges that were faced in those first years.

Along the way, Greg had an opportunity to very intentionally set the tone of the community to be welcoming and tolerant. This was primarily because Greg had has some very negative experiences with some of the very hostile communities in those early years. We talked a little bit about those intentional changes in the second half of our interview.

Our next interview was with Manuel “Wolfy” Wolfshant, who was also involved almost from the beginning. He began as a user, and quickly moved to building packages, which he needed for work, but decided to share with the world. He also was then, and is now, very involved in user support in the forums.

That interview can be read on the CentOS blog at https://blog.centos.org/2019/04/centos15-wolfy/

While at FOSDEM, in Brussels, in February, I talked with two members of the community. Mike McLean, a contributor to the project, and the author of the Koji tool that is used extensively in CentOS and Fedora, talked about his contributions:

And Brian Stinson, a more recent addition to the community, talked about his work in the CI and infrastructure of the project:

Our community is very dependent on people that actually use CentOS in production, because they are the people who find the problems, and who have insight into changes that should be made. They also are our most valuable contributors to user support, because they’ve been there, and know how to fix things when they break. Jeff Sheltren is one of those people, and has been using CentOS since the very beginning. Over time, he’s become part of the centos-qa group that helps test and package new versions of the distribution.

And finally, we have an interview with Karsten Wade, who was very instrumental in bringing CentOS into the Red Hat family, and continues to act as the liaison between the CentOS board, and Red Hat, although his position has changed over the years as I (Rich Bowen) have moved full time into that community manager role.

In the coming months, we’ll continue to do these interviews. If you’re part of the CentOS community, we’d like to hear from you - how you got involved, and how your role has changed as you’ve gotten more involved over the years. Get in touch with Rich - rbowen@centosproject.org - and we’ll talk.

Happy Birthday, CentOS. And here’s hoping that the next 15 years are even better. Come see us at Red Hat Summit next month to hear about what’s coming in CentOS 8, and what’s next for our community!

Dear CentOS enthusiast,

Another month into 2019, and we have a lot to tell you about.

#CentOS15

CentOS turns 15 this month!

We've been talking with some of the people who have been around since the beginning, and a few that joined us a little later on. And we'll be doing more of these interviews in the coming weeks and months. Here's a few of the interviews about how things have changed over the years.

Greg Kurtzer, who originally founded the project, talks about those early days.

Mike McLean talks a little about the transition over the years after that, and about CentOS joining the Red Hat family.

Brian Stinson talks about his responsibilities in the CentOS infrastructure and CI.

Manuel "Wolfy" Wolfshant talks about the path for someone to get involved in the project by jumping in and doing things that you see need doing.

If you would like to talk about your involvement in CentOS, please get in touch with Rich at rbowen@centosproject.org  You don't need to be one of the founders - just to have something interesting to say about your involvement, past, present, and future.

Changes coming to git.centos.org

If you contribute to the CentOS project, you need to be aware of changes that are coming to git.centos.org. To summarize, we're migrating from Gitblit to Pagure, effective April 8th. For the full details, please see this thread on centos-devel, and this new page in the wiki.

Releases and updates

While not as busy as February, we had a number of significant updates released in March.

Errata and Enhancements Advisories

We issued the following CEEA (CentOS Errata and Enhancements Advisories) during March:

SIG Updates

SIGs - Special Interest Groups - are where people work on the stuff that runs on top of CentOS. We have recently started having SIGs report quarterly, so we have just a few of them each month, getting through the entire list every 3 months.

Software Collections SIG

The Software Collections SIG reports a slow quarter, which is expected. Red Hat collections, from which this SIG builds, are released twice a year. This naturally leads to every other quarter being fairly silent.

Platform as a Service SIG

The PaaS SIG also reports a slow quarter. The main citizen of this SIG, OpenShift, is moving many of their components to containers, leaving less for the SIG to do.

However, there are some potential projects coming up. And, as always, there's lots of room for new contributors to come in and work on areas that interest them. Please do show up on the mailing list, or the IRC channel, to discuss what you'd like to work on.

Events

In two weeks, we'll be running a CentOS Dojo at Oak Ridge National Labs (ORNL), where we'll be featuring talks focused on the kind of scientific research computing that goes on there. You can see the schedule of speakers and sessions on the event website.

However, we have sold out all of the space at this event, and so registration is now closed.

At the end of the month, CentOS will be at the Open Infrastructure Summit (formerly known as OpenStack Summit), in Denver, in the community pod of the Red Hat booth. Come see us!

And we're ramping up towards Red Hat Summit, where we will be in the Community Central portion of the expo hall! This is one of our biggest events of the year, and we'd love to see you there, in Boston!

And, coming up, we're planning to run a CentOS Dojo in Boston, on the day before DevConf.US. The call for presentations is open, and we want to hear from you! Talks about anything you're doing in, on, or around CentOS is fair game. Submit your talks HERE.

For our next #CentOS15 profile, I spoke with Manuel "Wolfy" Wolfshant, who has been an active member of our community since the very beginning, shortly after we started working with the WhiteBox Linux community.

(You can see some of the other #CentOS15 interviews on YouTube.)

When Red Hat moved the business model from selling CDs to selling support, his company had a need to provide a Linux desktop operating system, and packages for it.

Wolfy says that his eye was caught by a news article about Johnny Hughes and the Mayor of Tuttle, Oklahoma, Jerry Taylor.

If you weren't around back then, I'll recap. Due to a failed server upgrade, the Mayor of Tuttle woke to find the generic Apache httpd welcome page, and the CentOS logo, on his city's website. He promptly emailed the CentOS project, threatening to turn them over to the FBI if they didn't undo their malicious hack of the site.

Johnny, being Johnny, responded calmly and respectfully, encouraging the Mayor to contact his IT department, and pointing him to resources to help get his site running again. Given this response, Mr. Taylor
got even angrier, and the conversation went downhill from there. But Johnny remained calm, polite, and professional, and helped guide the city IT department to a solution.

You can read more in the article from the Register at the time.

Impressed with Johnny's calm and helpful response, Wolfy went with CentOS, and has been a happy user for many years since that time.

His involvement in the project began with packaging drivers that were needed for machines in the office. It swiftly moved to other areas, including user support, translation, and starting the very active Romanian Linux user group, RLUG, which remains active today.

Over the years, he has worked on the release notes (for a time providing them in Romanian), packaging for Fedora, and the creation and maintenance of the minimal install kickstart during the CentOS 6 days.

He remains active in the IRC channel, on the mailing lists, and in the CentOS Forum, helping new users (and some experienced ones!) navigate their problems with the CentOS operating system. You can find him #centos-devel channel on Freenode IRC under the name 'wolfy', and on the centos-devel mailing list, answering user questions.

It's not a secret that the CentOS project has always been running on sponsored infra since the beginning of the journey. While over the years we sometimes lost some "sponsors", we are always happy to see new ones joigning us . That's especially true for the infra used to "seed" the CentOS distro and SIGs content to external mirrors, and even more in regions that are less covered.

While we have some nodes in North America and Europe, some other regions are less covered (if not at all). That's why we'd like to say thank you to Packet to have recently sponsored some bare-metal nodes that are now members of our msync network, including (but not limited) to regions like Asia (with one node in Japan !), Europe and America. Welcome !

The CentOS Atomic SIG has released an updated version of CentOS Atomic Host (7.1902), an operating system designed to run Linux containers, built from standard CentOS 7 RPMs, and tracking the component versions included in Red Hat Enterprise Linux Atomic Host.

CentOS Atomic Host includes these core component versions:

  • atomic-1.22.1-26.gitb507039.el7.centos.x86_64
  • rpm-ostree-client-2018.5-2.atomic.el7.x86_64
  • ostree-2018.5-1.el7.x86_64
  • cloud-init-18.2-1.el7.centos.1.x86_64
  • docker-1.13.1-91.git07f3374.el7.centos.x86_64
  • kernel-3.10.0-957.5.1.el7.x86_64
  • podman-0.12.1.2-2.git9551f6b.el7.centos.x86_64
  • flannel-0.7.1-4.el7.x86_64
  • etcd-3.3.11-2.el7.centos.x86_64

Download CentOS Atomic Host

CentOS Atomic Host is available as a VirtualBox or libvirt-formatted Vagrant box, or as an installable ISO, qcow2 or Amazon Machine image. For links to media, see the CentOS wiki.

Upgrading

If you’re running a previous version of CentOS Atomic Host, you can upgrade to the current image by running the following command:

# atomic host upgrade

Release Cycle

The CentOS Atomic Host image follows the upstream Red Hat Enterprise Linux Atomic Host cadence. After sources are released, they’re rebuilt and included in new images. After the images are tested by the SIG and deemed ready, we announce them.

Getting Involved

CentOS Atomic Host is produced by the CentOS Atomic SIG, based on upstream work from Project Atomic. If you’d like to work on testing images, help with packaging, documentation – join us!

You’ll often find us in #atomic and/or #centos-devel if you have questions. You can also join the atomic-devel mailing list if you’d like to discuss the direction of Project Atomic, its components, or have other questions.

Getting Help

If you run into any problems with the images or components, feel free to ask on the centos-devel mailing list.

Have questions about using Atomic? See the atomic mailing list or find us in the #atomic channel on Freenode.

A substantial number of released/updates were announced on Tuesday, March 19th, and are listed below. For timely announcements of these updates, subscribe to the centos-announce mailing list, at https://lists.centos.org/mailman/listinfo/centos-announce .

Errata and Enhancements Advisories

We issued the following CEEA (CentOS Errata and Enhancements Advisories) during March:

Errata and Security Advisories

We issued the following CESA (CentOS Errata and Security Advisories) during March:

Errata and Bugfix Advisories

We issued the following CEBA (CentOS Errata and Bugfix Advisories) during March:

 

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 February 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.

Dear CentOS enthusiast,

Another month into 2019, and we have a lot to tell you about.

CentOS is 15!

As you may have seen either at recent events, or on social media, we're getting ready to celebrate our 15th birthday! As part of that, Rich has been interviewing various people who were around in those early years, to get some of the back-story on how it all happened. You'll start seeing these interviews on the blog in the month of March.

This week, we have published an interview with Greg Kurtzer, who founded the project in the first place.

Later, we'll be publishing interviews with Karsten Wade, Manuel "wolfy" Wolfshant, and Mike McLean, with others to come.

If you would like to talk about your involvement in CentOS, please get in touch with Rich at rbowen@centosproject.org  You don't need to be one of the founders - just to have something interesting to say about your involvement, past, present, and future.
