    Fully virtualized ZTP deployments with DCI

    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.

    Directory structure built on OCP DCI agents

    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.

    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.
