    Addressing Challenges in Transitioning from IPI to ABI Installation

    In this post, we share how to deploy an entire Openshift Container Platform (OCP) cluster on a single baremetal server using the Assisted - Agent Based Installer (ABI) in a virtual environment with Libvirt VMs nodes. We highlight the benefits of ABI installation compared to the Installer Provisioner Infrastructure (IPI) installation that was our de-facto method.

    Automating JUnit test result verification for large applications using Ansible filter-plugins

    We are addressing DevOps or QA engineers who run and validate heavy test suites with thousands of tests in every JUnit file. These engineers often feel tired from having to manually create a list of failed tests to send back to the developers. While automated validation can help, it's challenging to implement it for real-world needs, such as making sure all tests are working or that all tests beginning with 'network' are passing. In this post, we will showcase an Ansible role that automates this type of validation.

    Networking Considerations for Distributed Deployment of Libvirt/KVM-Based OCP Clusters

    In previous blog posts, we have learned about the OCP on Libvirt project and the benefits it brings to us, with regards to the flexible deployment of OCP clusters where the nodes are virtual machines deployed on KVM. However, we have only covered the case of one single physical server. Can we use multiple physical servers to set up a lab with multiple, distributed deployment on Libvirt-based OCP clusters? The answer is yes! And we will explain the main requirements and challenges in terms of networking in this blog post.

    Troubleshoot pod traffic with nsenter and tcpdump tools

    When a pod fails to contact another network resource, logs might provide some hints, but sometimes the ultimate evidence of what is happening can be seen from a tcpdump packet capture; however, not all pods have tcpdump tools or even a shell to interact with. This blog post demonstrates how to use certain tools available in OpenShift and GNU/Linux to overcome those challenges and use tcpdump to validate network traffic in pods deployed on top of OpenShift clusters.

    How to build your own DCI dashboard

    Everydays, Red Hat DCI platform runs hundreds of jobs from different teams and partners, with all our products, with different purposes: debugging, certifications, tests, daily activities, etc. You may need to build a dedicated dashboard to follow your own specific activity, display graphical results, study some specific data or identify specific job behaviors. For such requirements, Google spreadsheet can provide you facilities to implement your ideas in a few minutes. In this blog post, you will learn how to quickly build a dashboard with Google spreadsheet by requesting DCI data, getting it dynamically and sending a pdf report by email periodically.

    Running CNF Cert Suite certification with dci-openshift-app-agent

    The dci-openshift-app-agent enables Cloud-Native Applications and Operators in OpenShift using the Red Hat Distributed CI service. It also includes the possibility of running a set of certification tools over the workloads deployed by this agent, including the CNF Cert Suite, which allows CNF Developers to test their CNFs readiness for certification. This blog post summarizes the main points to have in mind when running CNF Cert Suite with the dci-openshift-app-agent, also providing an example.

    Customizable Ansible pipelines for Telco partners using DCI

    Openshift Cloud Platform is meant to be the standard for modern Telco infrastructure. One of the goals of the Telco Partner CI Lab team is to test the installation of Openshift with all the requirements needed for Telco workloads. For one of our main partners, it means installing/upgrading an Openshift platform, some extra operators to handle specific hardware like SRIOV cards, and external products for storage or load balancing needed to handle CNFs to reduce any risk.

    Gerrit for GitHub users

    Most, if not all of the Distributed CI repositories, including this blog, are hosted in softwarefactory-project.io. Gerrit is the tool used to integrate the changes to such repositories. On the other hand, GitHub is the most popular service to host and integrate changes these days, this makes most of the developers familiar with GitHub to a certain extent. As such, this article attempts to explain to developers/contributors how to use Gerrit from the perspective of someone already familiar with GitHub.
