Delivering a host platform at the speed of light
Limited Capacity filling up

"When implementing true CI/CD you can deliver a host platform at a quicker cadence and high quality. This session walks through using Red Hat Opensource products such as Openshift, Jenkins, and Ansible to deliver a faster moving host completely containerized and gates developers/packagers. Every change gets validated and prevents bugs in code to be identified sooner by the person making changes. I will explore how Openshift + Jenkins Pipelines is a simpler comprehensive solution to enable CI/CD in any project based on lessons learned by delivering a host platform.

Container CI with Jenkins and Openshift
Limited Capacity full

"Containers are everywhere. Most applications today make use of multiple containers in their architecture. Very often, you need to test changes to one or more of your containers prior to moving them into production. Using Openshift as the platform and using Jenkins pipelines and the Jenkins Kubernetes plugin, I will present how to setup your workflow and help guide you on how to achieve efficient container CI.

Minishift: CI/CD in the palm of your hand
Limited Capacity filling up

"Developing a modern CI/CD workflow involves the integration of multiple technologies and applications/services. Openshift helps to simplify the provisioning, management and scaling of applications and, thanks to its tight integration with Jenkins, is a perfect choice for your CI/CD pipeline. This talk will provide an introduction to minishift[1] as a way for developers to have their own easy to implement, manage, and customize Openshift instance on their local development system, and how to use this minishift-based Openshift environment in conjunction with Jenkins to implement a full local CI-Pipeline.

Lessons Learned Implementing Builder Containers
Limited Capacity filling up

"Building, Composing and testing an Atomic release

In this session I'll show how we migrated our workflow from using Jenkins Job Builder on bare metal to running everything inside openshift with Jenkins pipeline and containers. We took an iterative approach of containerizing each piece of the pipeline and then moving those containers into openshift itself. I'll share lessons learned and what we found to be best practices.

CentOS CI: Shared Upstream CI Infra
Limited Capacity seats available

"The CentOS CI Infrastructure provides infrastructure resources for groups like the Fedora Atomic Pipeline (upstream), CentOS Linux (downstream), Openshift Origin (sorta-upstream in the CentOS PaaS SIG) and systemd (way-upstream). In this session, we'll go over some of the latest happenings in CentOS CI, talk about new features in the infrastructure, and describe the upstream - midstream - downstream community that we'd like to build together with you."

Distributed-CI: Fast Alone, Far Together.
Limited Capacity seats available

"Building an open source product includes a lot of testing. Being able to test in every possible hardware is unrealistic, given all the possibilities. Instead on focusing on acquiring more hardware to test, we propose that you focus on a smarter and more open way of validating that your product works on different environments. Enters Distributed-CI (DCI).

DCI is a platform where product teams constantly push the latest version of their product onto and partners constantly pull those bits and run their deployment on their own lab with their own configuration submitting back the test results. All that continuously and in an automated fashion.

Come discover how DCI has been used for projects like OpenStack, and learn how we are working on expanding this to Fedora."

Dogfooding Openshift with our CI infrastructure
Limited Capacity seats available

"In order to adapt in a demanding and fast-paced release cadence that Openshift follows as a productized distribution of Kubernetes, one of the things we had to rethink as members of the Openshift Continuous Delivery team over the past months was how to scale our CI infrastructure to quickly and efficiently verify, test, and merge developer changes across multiple Github repositories, that eventually get delivered to our customers while boosting developer productivity at the same time. Moving our CI infrastructure and testing workloads to run on top of Openshift has been a monumental effort. I am going to walk through our CI infrastructure architecture and how we are moving workloads from Jenkins to Openshift."

Gating Rawhide in Fedora
Limited Capacity seats available

"Features and stability are often mutually exclusive for early adopters. With Fedora, this means using "rawhide". One of the major complaints of rawhide users is that it is often broken, untested and hard to use with a lot of issues. There is an ongoing initiative to gate rawhide, with the aim of making it always at least Alpha quality. We are working to gate the nigthtly rawhide release, with the help of tools like OpenQA, ResultsDB, Greenwave, fedmsg and others. These tools will help decide whether or not the compose is ready for publication. This new process simplifies the life of early adopters and enables them to focus on helping us find real bugs. Come find out how the Fedora developers are bringing this to life and how you can implement it in your projects."

Kernel CI - How Red Hat can help
Limited Capacity seats available

"The upstream linux kernel code base is large and complex. The changes are voluminous. Testing these changes is challenging because of the speed and the diversity of the changes. Many companies are attempting tackle this problem through the use of automation and CI (continuous integration).

However, just throwing bots at the source code and building it can only solve so many problems. Upstream folks have said that kernel drivers account for the bulk of the churn in the code. Therefore any automated and CI solution needs to handle the diversity of hardware required to verify all the changes.

This talk will discuss what Red Hat is doing in this space and how we will contribute to stabilizing the upstream linux kernel using our Enterprise class hardware."
