CentOS Atomic Host 7.1706 Released
by Jason Brooks 18 Jul '17

18 Jul '17

An updated version of CentOS Atomic Host (tree version 7.1706), is now available. [1] CentOS Atomic Host is a lean operating system designed to run Docker containers, built from standard CentOS 7 RPMs, and tracking the component versions included in Red Hat Enterprise Linux Atomic Host. [1] https://wiki.centos.org/SpecialInterestGroup/Atomic/Download CentOS Atomic Host is available as a VirtualBox or libvirt-formatted Vagrant box, or as an installable ISO, qcow2 or Amazon Machine image. These images are available for download at cloud.centos.org. The backing ostree repo is published to mirror.centos.org. CentOS Atomic Host includes these core component versions: - atomic-1.17.2-9.git2760e30.el7.x86_64 - cloud-init-0.7.5-10.el7.centos.1.x86_64 - docker-1.12.6-32.git88a4867.el7.centos.x86_64 - etcd-3.1.9-1.el7.x86_64 - flannel-0.7.1-1.el7.x86_64 - kernel-3.10.0-514.26.2.el7.x86_64 - kubernetes-node-1.5.2-0.7.git269f928.el7.x86_64 - ostree-2017.5-3.el7.x86_64 - rpm-ostree-client-2017.5-1.atomic.el7.x86_64 Containerized kubernetes-master The downstream release of CentOS Atomic Host ships without the kubernetes-master package built into the image. Instead, you can run the master kubernetes components (apiserver, scheduler, and controller-manager) in containers, managed via systemd, using the service files and instructions on the CentOS wiki. The containers referenced in these systemd service files are built in and hosted from the CentOS Community Container Pipeline, based on Dockerfiles from the CentOS-Dockerfiles repository. These containers have been tested with the kubernetes ansible scripts provided in the upstream contrib repository, and they work as expected, provided you first copy the service files onto your master. Alternatively, you can install the kubernetes-master components using rpm-ostree package layering using the command: atomic host install kubernetes-master. Upgrading If you're running a previous version of CentOS Atomic Host, you can upgrade to the current image by running the following command: $ sudo atomic host upgrade Images Vagrant CentOS-Atomic-Host-7-Vagrant-Libvirt.box and CentOS-Atomic-Host-7-Vagrant-Virtualbox.box are Vagrant boxes for Libvirt and Virtualbox providers. The easiest way to consume these images is via the Atlas / Vagrant Cloud setup (see https://atlas.hashicorp.com/centos/boxes/atomic-host) For example, getting the VirtualBox instance up would involve running the following two commands on a machine with vagrant installed: $ vagrant init centos/atomic-host && vagrant up --provider virtualbox ISO The installer ISO can be used via regular install methods (PXE, CD, USB image, etc.) and uses the Anaconda installer to deliver the CentOS Atomic Host. This image allows users to control the install using kickstarts and to define custom storage, networking and user accounts. This is the recommended option for getting CentOS Atomic Host onto bare metal machines, or for generating your own image sets for custom environments. QCOW2 The CentOS-Atomic-Host-7-GenericCloud.qcow2 image is suitable for use in on-premise and local virtualized environments. We test this on OpenStack, AWS and local Libvirt installs. If your virtualization platform does not provide its own cloud-init metadata source, you can create your own NoCloud iso image.

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! The SIG meets weekly on Thursdays at 16:00 UTC in the #centos-devel channel, and 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.

Proposed changes to CentOS Atomic SIG meetings
by Jason Brooks 18 Jul '17

18 Jul '17

The members of the CentOS Atomic SIG have discussed adjusting our meeting schedule to accommodate more time zones, and to consolidate our meetings somewhat with the upstream Project Atomic meetings. We propose moving the CentOS Atomic SIG meeting to occur every two weeks, on Mondays, at 0400 UTC, to alternate with the every-two-week atomic sig meeting that occurs on Mondays at 1600 UTC. The idea is that the 0400 UTC meetings will accommodate community members in Bangalore, the 1600 UTC meeting will accommodate Eastern US and European members, and both times are accessible to the US west coast. The next Project Atomic community meeting is scheduled for July 24th and 1600 UTC, and the first CentOS Atomic SIG meeting on the new schedule would be at 0400 UTC on July 31st. The Project Atomic community meeting takes place on freenode in #atomic. We'd like to start holding the CentOS Atomic SIG meeting in #atomic as well, to promote collaboration with other atomic community members. Questions, concerns, etc? Regards, Jason

Updating golang in CentOS Extras?
by Niels de Vos 17 Jul '17

17 Jul '17

Hi, Currently CentOS Extras contains golang-1.4.2, but newer versions have been released since. Is there a plan for updating golang any time soon? In the CentOS Storage SIG we have a package (heketi) that started to depend on golang-1.6.2 (iirc). For us the older version of Golang in Extrasa results in preventing to update Heketi, and so users will not get the new features that are released upstream. If Extras can not get a newer version of Golang (soonish), what is the preferred approach to make an updated version of Golang available for repositories in a SIG? Thanks! Niels

Introduction to Cloud Programming with GreatFree
by Bing Li 17 Jul '17

17 Jul '17

*GreatFree? Cloud Programming? Why?* *Bing Li* *bing.li(a)asu.edu <bing.li(a)asu.edu>* GreatFree is a cloud programming environment I invented during the past seven years gradually. Using it, developers are able to program any distributed systems in any distributed computing environments rapidly and flexibly. To the best of my knowledge, this ought to be the first tool that attains this goal at this moment. You must not believe? If not, could you please tell me any other ones else? First of all, I need to define the term of programming from my prospective. Programming is the technology that offers developers the way to implement a software system with their knowledge in the specific domain only. According to that, when developers implement a distributed system, especially over the Internet, there is no such a tool, a programming environment or a programming language. Thus, two choices are always employed by them. The first one is to construct their systems over existing frameworks. Each of those frameworks focuses on one specific system only. Most domain-specific issues have already been resolved within the frameworks such that developers do not need to take into account them. Rather, developers work with script languages that are completely independent of the specific distributed environment. In contrast, another choice is to implement the system with a generic programming language. Unfortunately, this is a nightmare since they have to take care of not only domain knowledge of their systems but also thousands of details that have nothing to do with the specific domain. Although developers can implement distributed systems through the two alternative ways, simple or difficult, that is not programming from my perspective. Why is it so important to apply developers’ domain knowledge when implementing a software system? The answer is the freedom of development. Developers have the highest flexibility when programming distributed systems over the Internet with generic programming languages. However, it is too tough to tolerate such that only super guys might choose this way. We just forget about it. On the other hand, although it is convenient to do that with existing frameworks, developers lose almost all of the freedom to construct the system according to their expectations and knowledge since they are even not aware of any distributed issues. For consumers, that is fine. However, for developers, that is unacceptable. Without learning the internal structures, automobile developers are degenerated to drivers. Without grasping distributed knowledge, software developers can be replaced by high school students. Moreover, I believe programming with developers’ skills and knowledge is an activity full of joy. Proficient guys would like to manipulate a tool that provides them with rich options and choices rather than the fully-automatic one. Finally, from the academic point of view, it is weird that a programming tool is not available for the development of distributed system over the Internet. What scares computer scientists? With respect to the above discussions, I propose the tool, GreatFree, a new cloud programming environment, which allows developers to apply their distributed knowledge and skills as well as abandon any other irrelevant issues. Additionally, with its skillful designs, it also achieves the goal of rapid development. The concept of programming is realized in practice in the domain of the Internet distributed systems development. Now its initial version is available online. It is making progresses to push it to be the generic language for any distributed systems development. You are welcome to taste it. I appreciate so much for any suggestions! Finally, I need to indicate the relation between GreatFree and cloud programming. As one important instance of distributed systems over the Internet, no programming tools are available for cloud systems as well. Since it is so popular, I would like to entitle GreatFree together with the technology of cloud programming although GreatFree can also be used to program non-cloud systems. Incidentally, if you search the keyword, cloud programming, over the Web, you can get some results. Unfortunately, GreatFree is different from them in nature. Those stuffs look more like new generic languages with limited distributed features rather than the one to program the Internet-based distributed systems. You can get the presentation slides from the below link: *http://greatfree.lofter.com/post/1d231e0d_1069dcc5 <http://greatfree.lofter.com/post/1d231e0d_1069dcc5>* The APIs of GreatFree is as follows: *http://greatfree.0fees.us <http://greatfree.0fees.us>* The book and source code are downloadable at the link: *https://github.com/greatfree/Programming-Clouds <https://github.com/greatfree/Programming-Clouds>* Thanks so much!

openldap with ndb
by Samuel Bernardo 10 Jul '17

10 Jul '17

Hi, I just joined this mailing list because I compiled with success openldap with --enable-ndb=yes. I'm searching for documentation about package development and versioning, but I didn't find any clue about how to submit a patch for an existing package. I was surprised that CentOS 7 has man pages with support for openldap with ndb backend, but then I realised that openldap package was compiled with ndb module disabled. I pick source rpm of openldap and compiled it with a change in configure.in file to pass the checks. Than with the needed dev packages for MySQL Cluster I obtained a slapd with ndb support. So I ask for help how to submit my patch for review? Cheers, Samuel

Updated CentOS images for Vagrant
by Laurentiu Pancescu 05 Jul '17

05 Jul '17

Hello Vagrant users, we just released updated CentOS images for Vagrant, v1706.01. That's not that interesting in itself, since there are just updated packages (nothing else), but Hashicorp moved the hosting of all Vagrant images away from Atlas, to Vagrant Cloud. To add to the confusion, they didn't move it back to vagrantcloud.com, where it used to be - they host it on app.vagrantup.com. They wrote that they will provide redirects, so the move should be transparent for end users. I didn't try if SCL Vagrant still works, but a small tool I wrote, Endymion, still uses Atlas links and works just as before (except for an extra redirect). On the positive side, "centos/7" is now the fourth most popular image on Vagrant Cloud: https://app.vagrantup.com/boxes/search If you encounter any problems after the move away from Atlas, please post a message to the list. Best regards, Laurențiu https://www.hashicorp.com/blog/vagrant-cloud-migration-announcement/ https://github.com/lpancescu/endymion
