DevNation 2015 - Arun Gupta, Thomas Qvarnström - DevOps with java ee

Red Hat Developer Program

Techniques such as automated builds and testing, continuous integration and continuous deployment allow software to be developed to a high standard and easily packaged and deployed to test environments, resulting in the ability to rapidly, reliably and repeatedly push out enhancements and bug fixes to customers at low risk and with minimal manual overhead. What container-agnostic tools are available for testing, continuous integration and deployment of a Java EE application ? This talk will start with how to package Java EE application “operating environment” such as Operating System, JVM, Database, dependencies, and other configuration in a reusable format, such as Docker. It explains how to replicate the environment for development, testing, staging, and production minimizing the impedance mismatch between them. A quick overview of Arquillian and how it helps in a automated testing across multiple Java EE containers is shown. How functional testing, code coverage, performance and other aspects for going in to production will be discussed. Using Arquillian against Docker containers will be explained as well. Finally, configuring Jenkins for Continuous Integration and setting up deployment pipelines will show how to take an application from push-to-production and achieve almost 100% automation.

DevNation 2015 - Paulus Bakker & Sander Mak - Provisioning the Internet of Things

Red Hat Developer Program

How do we get our software out on the Internet of Things (IoT)? Many current deployment practices won’t work. Devices can be occasionally connected, through low-bandwidth networks, but are generally outside of direct control. Manually shuffling around binaries is not an option. Apache ACE is an open source Java provisioning tool that tackles such challenges. This software distribution framework allows you to centrally manage and distribute software components, configuration data, and other artifacts to target systems. In this session, learn how Apache ACE enables you to push out incremental updates and manage numerous devices. We’ll show how to update and extend a fictional car entertainment system using Apache ACE.

DevNation 2015 - Paul Bakker - Kubernetes: Beyond the basics

Red Hat Developer Program

Kubernetes has answers to many questions related to clustering and the required low-level networking. When using Kubernetes for real live deployments we need more than those lower-level solutions however. We need things like automated deployments, load balancing for web applications, blue/green deployments and monitoring. This is all possible with Kubernetes when we start to look at Kubernetes as an API. In this talk you will learn to embrace the Kuberentes API and some of the patterns, tools and mechanisms we developed and use around Kubernetes to prepare for production grade deployments.

DevNation 2015- Michael Hrivnak - Docker for developers

Red Hat Developer Program

Docker is not just for deployment. As a developer, there are many ways Docker can make you more productive, regardless of how your app gets deployed. In this session, you'll learn practical strategies for using Docker, including how to: Run unit tests locally in multiple environments with almost no overhead. Make your integration tests easy for anyone to run by distributing them in a Docker image. Simulate advanced network topologies, especially for a service-oriented architecture. Make a Docker image in 5 minutes or less that produces builds from a consistent environment. Isolate database state changes in your test suite by using a pool of disposable containers.

Docker and JBoss - the perfect combination

Red Hat Developer Program

For this session we have Marek Goldmann who leads Docker related initiatives at Red Hat.  Abstract Docker is a tool for building portable Linux containers around an application. If you are unfamiliar with Docker, or have heard of it but never used it, then you should definitely come to this session because containers are the new virtualization. Docker is a revolution in thinking about software distribution. It makes the process of creating images with the whole application stack (OS + application server + application itself) easy and extremely fast. You can share them easily too, and images behave the same way on different machines. Differences between development and production environments are a thing of the past. But that's not everything - Docker helps you run images too by providing an easy to use interface. Sounds like magic, huh? In this session, right after introduction to Docker, Marek will dive into examples showing how you can leverage this tool to create a deployment environment for your applications. You will see how to cluster JBoss EAP and deploy an application to it. Marek will share some tips and tricks too: for example how to manage logs or customize the configuration of JBoss EAP to be able to deploy your applications. About Marek Marek joined Red Hat in January 2009 and started hacking on Cloud-related JBoss projects. Currently Marek leads the WildFly integration effort with the Fedora operating system, and makes sure that JBoss' projects run well on Docker.

Managing Windows Updates with Ansible in Red Hat Enterprise Linux

Jose Angel Munoz

Introduction When looking for installation instructions of Ansible under RHEL, I have always have found two ways: With epel-release (Which I don't like just because I want to keep my system clean). From source code (Which I don't like either for the same reason). Packages Installation For me, the right approach for the installation is installing from the Official Red Hat Repository and following the instructions below: Select the server-extras-beta repository (Here we will find the ansible packages) subscription-manager repos...

Achieving Deployment Excellence with Red Hat OpenShift.io

Rob Terzi

Recently, the focus on the continuous delivery of value has created a lot of interest in microservices, CI/CD, and containers. The idea is that microservices are small and well defined enough to enable rapid innovation, automated testing, and frequent deployments with minimal risk. This is made possible by adopting continuous integration and continuous delivery pipelines. CI/CD requires the ability to quickly, easily, reliably, and automatically create and tear down complete execution environments. Linux containers address this need by creating lightweight...

Benchmarking nftables

Phil Sutter

Since I've learned about nftables, I heard numerous times that it would provide better performance than its designated predecessor, iptables. Yet, I have never seen actual figures of performance comparisons between the two and so I decided to do a little side-by-side comparison. Basically, my idea was to find out how much certain firewall setups affect performance. In order to do that, I simply did a TCP stream test between two network namespaces on the same system and then added...
