Introduction to Docker, December 2014 "Tour de France" EditionJérôme Petazzoni
Docker, the Open Source container Engine, lets you build, ship and run, any app, anywhere.
This is the presentation which was shown in December 2014 for the "Tour de France" in Paris, Lille, Lyon, Nice...
Talk held by Jaime Melis at the CentOS Dojo in Cologne, August 4th (http://wiki.centos.org/Events/Dojo/Cologne2014)
In this talk we talk about OpenNebula from the perspsective of the CentOS, explaining tips and considerations for power users.
OpenNebula Conf 2014: CentOS, QA an OpenNebula - Christoph GaluschkaNETWAYS
CentOS, the Community Enterprise OS, uses Opennebula as virtualization plattform for its automated QA-process. The opennebula setup consists of 3 nodes, all running CentOS-6, who handle the following tasks:
– sunstone as cloud controller
– local mirror/DNS-Server/http-Server for the VMs to pull in packages
– one VM to run a jenkins instance to launch the various tests (ci.de.centos.org)
– nginx on the cloud controller to forward http traffic to the jenkins VM
A public git repository (http://www.gitorious.org/testautomation) is used to allow whoever wants to contribute to pull the current test suite – t_functional, a series of bash scripts used to do funtional tests of various applications, binaries, configuration files and Trademark issues. As new tests are added to the repo via personal clones and merge requests, those tests first need to complete a test run via jenkins. Each test run currently consists of 4 VMs (one for each arch for C5 and C6 – C7 to come), which run the complete test suite. All VMs used for theses tests are instantiated and torn down on demand, whenever the call to testrun a personal clone is issued (via IRC).
Once completed successfully, the request is merged into the main repo. The jenkins node monitors this repository and which automatically triggers another complete test run.
Besides these triggered test runs, the test suite is automatically triggered daily to run. This is used to verify functionality of published updates – a handfull of failty updates have allready been discovered this way.
Besides t_functional, the Linux Test Project Suite of tests is also run on a daily basis, also to verify functionality of the OS and all updates.
The third setup is used to test the available and functional integrity of published docker images for CentOS.
All these tests are later – during the QA-phase of a point release – used to verify functionality of new packages inside the CentOS QA-Setup.
This presentation discusses using the libvirt virtualization API for controlling bhyve virtual machines under FreeBSD.

Talk held by Jaime Melis at the CentOS Dojo in Cologne, August 4th (http://wiki.centos.org/Events/Dojo/Cologne2014)
In this talk we talk about OpenNebula from the perspective of the project, the technology and the community.
The talk is about operating system virtualization technology known as OpenVZ. This is an effective way of partitioning a Linux machine into multiple isolated Linux containers. All containers are running on top of one single Linux kernel, which results in excellent density, performance and manageability. The talk gives an overall description of OpenVZ building blocks, such as namespaces, cgroups and various resource controllers. A few features, notably live migration and virtual swap, are described in greater details. Results of some performance measurements against VMware, Xen and KVM are given. Finally, we will provide a status update on merging bits and pieces of OpenVZ kernel to upstream Linux kernel, and share our plans for the future.
[DockerCon 2019] Hardening Docker daemon with Rootless modeAkihiro Suda
https://dockercon19.smarteventscloud.com/connect/sessionDetail.ww?SESSION_ID=281879
Docker CE 19.03 is going to support "Rootless mode", which allows running the entire Docker daemon and its dependencies as a non-root user on the host, so as to protect the host from malicious containers in a simple but very strong way. Rootless mode is also attractive for users who cannot get `sudo` permission for installing Docker on shared computing machines. e.g. HPC users. In this talk, Akihiro Suda, the author of the Rootless mode (PR: moby#38050), will explain how users can get started with Rootless mode. He will also explain the implementation details of Rootless mode and planned enhancements such as LDAP integration.
(auto)Installing BSD Systems
The auto-installation methods you can use to set BSD operating systems up and running
-----
After more than a decade in touch with systems like FreeBSD, not by just consuming them as an end-user but also by working as a sysadmin or by developing 'BSD Powered' solutions, you might fall into pitfalls by not easily finding a way to fully automate their installations. The good news: it's possible and it's not as complicated as you might think!
Today's needs regarding automating things like an O.S. installation can save you a lot of time; Kickstart or Preseed files are not the only ways of doing it. One can even combine or expand it all to add patching and updating routines into the game.
Here we are not talking about a one-click solution or something like querying an API endpoint to provide you with a shiny virtual machine; no. The main idea behind this talk is to present you with a tool-set and ways of (auto)installing your machines, let's say, using a NetBSD operating system; be it virtual, or not.
Inspired by talks like the ones showing how OpenBSD Amsterdam sets its virtual machines up, we get together and share thoughts, ideas and setups to get DHCP, iPXE and diskless systems in our favor to set our infrastructure up and running.
Concerned about the first boot and keeping up with services' configurations and consistencies, we also talk about getting Puppet to watch it for you. Considering plain text passwords no one wishes to host in a Git repository, EYAML to the rescue!

This is the final in a series of slide shows that follow my UCLA winter 2010 course titled Cradle to Cradle: Closed Loop Systems. This interdisciplinary course contributes to the school's Certificate of Global Sustainability.
Cradle to Cradle® Certification is a multi-attribute eco-label that assesses a product’s safety to humans and the environment and design for future life cycles. The program provides guidelines to help businesses implement the Cradle to Cradle framework, which focuses on using safe materials that can be disassembled and recycled as technical nutrients or composted as biological nutrients. Unlike single-attribute eco-labels, MBDC’s certification program takes a comprehensive approach to evaluating the sustainability of a product and the practices employed in manufacturing the product. The materials and manufacturing practices of each product are assessed in five categories: Material Health, Material Reutilization, Renewable Energy Use, Water Stewardship, and Social Responsibility. Click here for complete description of Certification Criteria .
Tish Tablan will deliver a presentation on the Cradle to Cradle® framework and how building professionals can use it to create more sustainable buildings. This webinar provides 1 GBCI CE for LEED Credential Maintenance.

Gentoo Linux, or Why in the World You Should Compile EverythingDonnie Berkholz
Gentoo Linux is a special flavor of Linux that can be automatically optimized and customized for just about any application or need. Extreme performance, configurability and a top-notch user and developer community are all hallmarks of the Gentoo experience.
As a leader of Gentoo, I will provide an overview of how it works from a developer's and a user's point of view, and why you should be running it especially if you're:
- In need of an awesome development environment;
- Interested in learning what's inside the black box of Linux;
- OCD about having a perfectly configured setup; or
- Building an embedded, minimal system or a high-performance cluster.
If there's interest, I can also talk about future developments on the horizon for Gentoo, package management in general, etc.
This lecture goes into basic info about Linux and the GNU Project.

Running Applications on the NetBSD Rump Kernel by Justin Cormack eurobsdcon
Abstract
The NetBSD rump kernel has been developed for some years now, allowing NetBSD kernel drivers to be used unmodified in many environments, for example as userspace code. However it is only since last year that it has become possible to easily run unmodified applications on the rump kernel, initially with the rump kernel on Xen port, and then with the rumprun tools to run them in userspace on Linux, FreeBSD and NetBSD. This talk will look at how this is achieved, and look at use cases, including kernel driver development, and lightweight process virtualization.
Speaker bio
Justin Cormack has been a Unix user, developer and sysadmin since the early 1990s. He is based in London and works on open source cloud applications, Lua, and the NetBSD rump kernel project. He has been a NetBSD developer since early 2014.

Deployment of WebObjects applications on CentOS LinuxWO Community
With the rise of cloud computing and the death of the Xserve, learn how you can deploy your WebObjects applications on a CentOS server. You will also get tips about how to secure your server so that you don't get hack.
Current experience shows that a lot of developers working on Xen/Linux kernel use mainly only small set of debugging tools. Often they are sufficient for generic work. However, when unusual problem arises which could not be easily debugged using known tools sometimes they are trying to reinvent the wheel. Goal of this session is to present wide range of debugging tools starting from simplest one to most feature reach solutions in context of Xen/Linux kernel debugging. It will describe pros and cons of printk (serial, debug console, etc.), gdb, gdbsx, kgdb, QEMU, kdump and others. Additionally, there will be some information about possible new solutions and current kexec/kdump developments for Xen.
