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:
    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.

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.

Dear CentOS enthusiast,

We wish you a happy and prosperous 2019, full of CentOS!

The following releases also happened during December:

 

SIG Updates

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

Cloud SIG

Last month the Cloud SIG produced a detailed quarterly report, which you can read in a separate post. This kind of detailed report is what we'd love to see from other SIGs in the future.

Software Collections SIG

The Software Collections SIG has also published a quarterly report, covering their progress in the last few months.

Other SIG Reports

Due to so many people taking time off in December to spend time with friends and family, several other SIG reports are running a little late. Don't worry, they're on the way, and you can see them here, on blogs.centos.org, in the next week or two. Thanks for your patience!

Events

Upcoming events

Coming up in February, we'll be participating in FOSDEM, with a table in the expo area, as most years. Drop by for all your CentOS sticker needs, or to tell us about what you're doing with CentOS! You can find out more about FOSDEM on their website at https://fosdem.org/2019/.

And, on the day before FOSDEM starts, we'll be holding our annual CentOS Dojo, at the Marriott near Grand Place. We'll have a full day of technical presentations (two tracks!) and, of course, the always valuable hallway track where you can talk with other people in the CentOS community. Attendance is free, but we need you to register, so that we can plan. Details, the schedule, and the registration like, are all on the event website at https://wiki.centos.org/Events/Dojo/Brussels2019

There's a lot of other events around FOSDEM, too, that you might want to check out. These are loosely called the FOSDEM Fringe, and are listed here: https://fosdem.org/2019/fringe/

Contributing to CentOS Pulse

We are always on the look-out for people who are interested in helping to:

  • report on CentOS community activity
  • provide a report from the SIG on which you participate
  • maintain a (sub-)section of the newsletter
  • write an article on an interesting person or topic
  • provide the hint, tip or trick of the month

01 September 2018 - 31 November 2018

Purpose

Packaging and maintaining different FOSS based Private cloud infrastructure applications that one can install and run natively on CentOS.

https://wiki.centos.org/SpecialInterestGroup/Cloud

Membership Update

We are always looking for new members, especially representation from other cloud technologies.

The SIG agreed to replace the inactive SIG Chair, Kushal Das, with new chair Rain Leander, at the recent SIG gathering at CERN, in October.

No SIG members have been added in this quarter. However, the SIG membership list was updated on the SIG wiki page to reflect reality.

Releases and Packages

RDO

Aug 27 - Aug 31 Rocky Release https://blogs.rdoproject.org/2018/09/rdo-rocky-released/

Interesting features in the Rocky release include:

  • New neutron ML2 driver networking-ansible has been included in RDO. This module abstracts management and interaction with switching hardware to Ansible Networking.
  • Swift3 has been moved to swift package as the “s3api” middleware.

Other improvements include:

  • Metalsmith is now included in RDO. This is a simple tool to provision bare metal machines using ironic, glance and neutron.

The full release notes are at https://releases.openstack.org/rocky/highlights.html

Sep 10 - Sep 14 Stein Release Project Team Gathering

Oct 22 - Oct 26 Stein-1 milestone

Health and Activity

The Cloud SIG remains fairly healthy. However, it is still, for the most part, a monoculture containing only OpenStack.

In recent days, CloudStack has indicated an interest in once again participating in the SIG, with an eye towards providing CloudStack 4.11.2.0 rpms, and having more visibility in CentOS 8, in particular, once that is released.

Currently OpenStack group is focusing in preparing CentOS 8 support (E.g: python3, podman) through a fork of Fedora 28. This repository is used in upstream and downstream CI to reduce the gap as much as possible when CentOS 8 will be available.

Issues for the Board

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

We're looking forward to seeing all of you in Brussels next month!

The annual FOSDEM CentOS Dojo will be happening, as usual, on the Friday
before FOSDEM starts - February 1st, 2019 - at the Marriott Grand Place,
just a few minutes walk from Grand Place.

We do ask that you register, so that we can plan for space, budget, and
coffee breaks. We are currently about two thirds full, so don't wait!

More details, including the full schedule of presentations, and the
registration link, are on the event website:

https://wiki.centos.org/Events/Dojo/Brussels2019 

See you in Brussels!

Once upon a time, there was a repository called fasttrack, and it used to get low priority updates before going through all the usual checks.

Eventually, that repo was deprecated, we couldn't delete it without breaking compatibility, so it just stayed there, empty and silent.

A few days ago, a bug appeared in bind, that was giving headaches to many people, we had a fix and wanted to give the users an option without waiting for the official build, so we decided to bring fasttrack back to life.

What will it be for?
Well, exactly for cases like this, simple fixes that the CentOS QA team or community members come up with, and helps users while they wait for the official solution.

How do I enable it?
sudo yum-config-manager --enable fasttrack
Then run yum update as usual.

What are the steps?
1) Submit your bug in https://bugs.centos.org/
2) If you have a patch, or a reference to the program's bug tracking system, add it to the bug.
3) This is the most important step, "Be patient!!!"
4) If all goes well, and we like the patch, we'll create a temporary build and point you to it in the bug entry.
5) You'll have to install and test that this build works.
6) If not done already, submit a bug in https://bugzilla.redhat.com/ and point it to the one created in CentOS.
7) Once all of this is done, we'll sign and push it to the fasttrack repo for everybody to use.

Please keep in mind that this repo is for "temporary" fixes, until Red Hat comes up with the real solution.

If you have any problems, please report back through the usual channels (irc, forums, Bug Tracker, Mailing Lists, etc)

Pablo.

Update: Added steps. all this is WiP at the moment.

2018-12-12: We published new Vagrant images, v1811.02, fixing CentOS bug 15552 (wrong permissions on file /etc/sudoers.d/vagrant cause visudo -c to report an error, which can result in problems with Puppet).

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 November 30th, 2018.

Waiting on CentOS infra for having an appliance shipping ovirt-guest-agent, hopefully with CentOS 7.6 GA.

Why your project should participate in a CentOS SIG

Last week we published an overview of Why your project should participate in a CentOS SIG. If you're involved in any open source project, and want it to have more exposure and better testing on CentOS, the SIGs are designed specifically for you. Join an existing SIG, or propose a new one that better fits your project.

The CentOS Container Pipeline Project

Did you know that CentOS Container Pipeline project offers an automated way of building CetntOS based containers? All you need to do to get started is add details about your open-source project to the container-index repository The service picks things up from there and rebuilds your container image every time you push a commit to the specified branch!

The team recently revamped the service architecture to be based on OpenShift. The service is hosted on CentOS infrastructure but can be easily deployed in your own infrastructure.

The project also scans container images for rpm, pip, npm and gem package updates; capabilities of resulting container; and integrity of RPM data. You can also leverage parent-child relationship to trigger a build of child image(s) whenever its parent image gets updated!

Got questions? Contact the team on 'container-apps' channel on Mattermost.

Events

Recent events

In November, we had a small presence at SuperComputing 18 in Dallas. While there, we talked with a few of the teams participating in the Student Cluster Competition. As usual, student supercomputing is #PoweredByCentOS, with 11 of the 15 participating teams running CentOS. (One Fedora, two Ubuntu, one Debian.)

Our congratulations go out to the team from Tsinghua University, who won this year's competition!

Upcoming events

In December, we'll be at the Red Hat booth at Kubecon in Seattle. Drop by for all of your CentOS sticker needs.

Coming up next year, we have two Dojos in the early part of the year that you'll want to be at.

In Europe, we have our annual Dojo at FOSDEM. It will be held at the Grand Place Marriott on Friday, February 1st, 2019. Registration is free, but we do need you to register, so that we can adequately plan. The schedule, details, and registration, are available on the event web page.

And, in North America, we have just announced our upcoming Dojo at Oak Ridge National Labs, on Tuesday, April 16th, 2019. Initial information, and the call for presentations, is on the event web page.
