Chef is awesome, but it’s also very easy to go overboard. In terms of testing and maintainability, sometimes its better to refactor your long recipe into an LWRP. As your infrastructure evolves, so should you cookbooks. But at some point your bound to have a cookbook 500+ lines of antiquated logic. How do you refactor such a large chunk of code that is critical to your infrastructure? How much logic should me moved into other cookbooks? How much logic should be extracted into LWRPs? How much logic should be moved out of Chef, into Ruby, and packaged as a gem?

Background processing with Resque

Nicolas Blanco

Resque is a background processing library for Ruby that allows processing of jobs asynchronously via a queue using Redis. It uses workers that listen for jobs on queues and process them, and includes plugins like resque-lock to prevent duplicate jobs and resque-loner to relaunch failed jobs. The document discusses setting up Resque with God for monitoring workers, handling signals, and restarting workers gracefully on the bookandgolf.com project which synchronizes golf course data from multiple APIs into Redis.

Brian K. Vagnini

Git is a version control system that allows tracking changes to files. It works by taking snapshots of files and storing reference hashes locally. There are three main stages - modified, staged, and committed. Git recommends following a workflow that involves making changes on a development branch, testing, merging to master, and pushing to a remote repository. Common commands include git add to stage changes, git commit to commit them locally, and git push to push to a remote. Branches allow parallel development, and git merge is used to integrate branches.

Infrastructure = code - 1 year later

Christian Ortner

This document discusses using infrastructure as code to automate server setup and deployment using Ansible. It outlines benefits like reducing human error, allowing developers and operations teams to work seamlessly through continuous integration and testing. Specifics of the infrastructure as code stack used are covered, including Ansible for configuration management, Docker for containers, and Vagrant for local virtual machine provisioning. Challenges and lessons learned around testing, debugging, and migrating existing systems are also presented. The overall message is that infrastructure as code takes time to implement but results in major improvements to deployment speed, reliability, and ability to rapidly iterate.

Background Jobs with Resque

homanj

As more and more web applications integrate with third-party APIs and other external data, processing those external resources in the background more and more important. A simple job runner is a great start, however as your load increases, you very quickly outgrew that simplistic queuing system. We will cover where getting started using Resque and Redis, how to test your jobs, when it makes sense to use Resque, implementations of Resque in other languages, and look how I've used Resque.

Kubernetes: Wie Chefkoch.de mit Containern arbeitet

Per Bernhardt

Container erfreuen sich in letzter Zeit enormer Beliebtheit, da sie Systemadministratoren und Entwicklern eine einfache und gemeinsame Verwaltung Ihrer Infrastruktur ermöglichen. Je nachdem wie die Systemlandschaft aufgebaut ist und wie viel Traffic sie bedienen muss, reicht ein einfaches „docker build + docker run“ aber nicht mehr, um die Container in allen Lebensphasen einer Anwendung verwenden zu können. In diesem Vortrag möchte ich zeigen, weshalb wir uns bei Chefkoch.de deshalb für die Einführung des Orchestrierungs-Tools Kubernetes entschieden haben und wie wir damit Container sowohl in der Entwicklung als auch in allen Testphasen und letztendlich auch in Produktion verwenden.

Chef introduction

FENG Zhichao

Chef is an infrastructure automation tool that allows users to define and maintain server configurations. It uses recipes, resources, cookbooks and roles to provision and configure servers. Chef works by installing a Chef client on nodes that runs recipes to configure the node according to cookbooks. The Chef server stores cookbooks and node data. Users can write recipes in Ruby syntax to define what configuration should be applied to nodes.

Atmosphere 2014: Really large scale systems configuration - Phil Dibowitz

PROIDEA

For many years, Facebook managed its systems with cfengine2. With many individual clusters over 10k nodes in size, a slew of different constantly-changing system configurations, and small teams, this system was showing its age and the complexity was steadily increasing, limiting its effectiveness and usability. It was difficult to integrate with internal systems, testing was often impractical, and it provided no isolation of configurations, among many other problems. After an extensive evaluation of the tools and paradigms in modern systems configuration management – open source, proprietary, and a potential home-grown solution – we built a system based on the open-source project Chef. The evaluation process involved understanding the direction we wanted to take in managing the next many iterations of systems, clusters, and teams. More importantly, we evaluated the various paradigms behind effective configuration management and the different kinds of scale they provide. What we ended up with is an extremely flexible system that allows a tiny team to manage an incredibly large number of systems with a variety of unique configuration needs. In this talk we will look at the paradigms behind the system we built, the software we chose and why, and the system we built using that software. Further, we will look at how the philosophies we followed can apply to anyone wanting to scale their systems infrastructure. Phil Dibowitz - Phil Dibowitz has been working in systems engineering for 12 years and is currently a production engineer at Facebook. Initially, he worked on the traffic infrastructure team, automating load balancer configuration management, as well as designing and building the production IPv6 infrastructure. He now leads the team responsible for rebuilding the configuration management system from the ground up. Prior to Facebook, he worked at Google, where he managed the large Gmail environment, and at Ticketmaster, where he co-authored and open sourced a configuration management tool called Spine. He also contributes to, and maintains, various open source projects and has spoken at conferences and LUG’s on a variety of topics from Path MTU Discovery to X509.

Apps Break Data

Ivo Velitchkov

How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
