Technical guides for OKD and Kubernetes environment setups

Technical documentation outlines procedures for customizing and setting up container orchestration environments.

One guide details the process of building a custom OKD Machine OS image. Because OKD uses a custom version of Fedora CoreOS (FCOS) with an immutable filesystem managed by rpm-ostree, modifying the kernel can be complex. The process involves cloning the okd-machine-os repository with all Git submodules and utilizing tools such as podman and buildah to navigate the layered build environment.

Another guide provides a workflow for a rapid Kubernetes development environment setup using Minikube. The recommended stack includes Jaeger for tracing, Prometheus for instrumentation and metrics, and Grafana for metric visualization. The setup utilizes Traefik as an Ingress controller and demonstrates how to use Helm to generate deployment templates for these tools.
