In this guided lab you’ll deploy a generic nginx Helm chart step by step — from its default values (which fail) to an OpenShift-compatible configuration (which succeeds) — diagnosing each failure along the way with oc/kubectl. You’ll learn: Why OpenShift’s Security Context Constraints (SCC) prevent containers from running as root How OpenShift assigns a non-root UID per namespace, and why that breaks images that assume root How to adapt a chart (here, the official nginx image) to run under restricted-v2 Complete this lab in 20-30 minutes.
