DCI Analytics empowers teams to query CI data with an intuitive DSL and visualize results dynamically. Its fast, dual-store architecture and guided autocomplete make it easy to spot trends, diagnose issues, and continuously improve your pipelines.

OpenShift deployments offer multiple options to define IP addresses for servers. IPv4 configuration is well-known, and most services and appliances provide the means to define IPv4 addresses. However, when it comes to IPv6, new concepts are introduced, and standard services do not provide the same configuration capabilities as they do for IPv4. Besides, embracing IPv6 is crucial for scalability today. In this blog post, we will highlight the components that require IPv6 in OpenShift and demonstrate how to configure static IPv6 addressing during installation using NMState through DCI. This will be the first in a series of blog posts discussing the options available for setting up IPv6.

We have already presented some particular deployments where you have seen the benefits of leveraging DCI to deploy your OpenShift clusters by following the ZTP approach. In this blog post, we want to emphasize what are the kind of use cases that are currently covered by DCI, and what’s coming next in the support of ZTP deployments. You will see how DCI can help you to configure the cluster you need with a wide variety of cases.

An introduction to the DCI RHEL Agent's architecture, installation, and usage

This blog post showcases the steps needed (with automated examples) to get an Agent-Based Installer (ABI) cluster in a Virtual Lab up and running

This blog post will show you how you can deploy a fully virtualized ZTP environment, where both the hub and spoke cluster will be placed in virtual machines managed with KVM. For this purpose, DCI will be used as key continuous integration tool to support the installation of both the hub and spoke cluster. This is useful for quickly troubleshooting of issues, not depending on a full baremetal infrastructure for that. The differences between the deployment on baremetal and virtualized scenarios (even though DCI works seamlessly in both cases) will be presented, also highlighting the key aspects you need to have in mind when deploying this pipeline with virtual machines. Best practices and lessons learned will be also shared.

One of the OCP deployment use cases getting more attention lately is the GitOps-ZTP. This article describes how to use DCI to deploy an OCP cluster following this methodology.

As Kubernetes continues to evolve, new features are introduced while older, deprecated APIs are phased out. This cycle ensures the platform remains cutting-edge, but it also presents a significant challenge during upgrades, especially for applications relying on deprecated APIs. In this post, we'll discuss Kubernetes upgrade readiness, the complexities of API deprecation, and how we can detect soon-to-be-removed APIs—both statically and dynamically invoked—using Red Hat Best Practices Certification for k8s.

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.

This blog post aims to guide DCI users on locating the resources provided by our DCI agents (dci-openshift-agent, dci-openshift-app-agent, and dci-pipeline) on the server used to launch these agents. It also includes an explanation of each piece of installed code. Having this information clearly described is crucial for troubleshooting, as it helps users know where to look in the DCI agents' code.

The DCI openshift agents bring transparent support to use the newly added Image Digest Mirror Sets (IDMS) in OpenShift. The main use of IDMS is in disconnected clusters. The IDMS provides the registry mirroring functionality for images that are not reachable due to network constraints.

An introduction to DCI labs implementation of disconnected environments.

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.

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.

One of the main challenges during the workload migration to OCP-4.12 is the massive deprecation of beta APIs. In this post, we will discuss how to identify the APIs that are going to be deprecated and how DCI could simplify this task for you.

The storage tester role, shipped in the DCI OpenShift Agent, allows the user to test a storage class behavior during an upgrade. It can be seen as an example of resilience testing that can be done with DCI on a cluster.

This post will describe what is a pipeline in the DCI world and how to use it step by step to create workflows in our testing environment.

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.

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.

Red Hat provides mainly infrastructure software like RHEL, OpenShift or OpenStack. These are established technologies for our customers but also for our partners.
