    Detecting To-Be-Removed APIs for Kubernetes Upgrade Readiness with Red Hat Best Practices Certification for k8s

    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.

    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.

    Running Red Hat Best Practices for Kubernetes test suite 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 Red Hat Best Practices for Kubernetes test suite (former 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 the certsuite with the dci-openshift-app-agent, also providing an example.
