Why Kubernetes Pod Security Standards Still Leak

In this episode of DevOps Daily with Fexingo, Lucas and Luna dig into a subtle but dangerous gap in Kubernetes Pod Security Standards (PSS) — the admission controller that replaced PSPs. They walk through a real-world example: a team running a sidecar container with a privileged profile, bypassing the baseline policy because PSS applies to pods but not to init containers and ephemeral containers at the same granularity. Lucas explains how the 'restricted' profile doesn't block volume mounts that allow host-path writes from a non-root user, and how a compromised workload can pivot to the node without ever triggering a violation. Luna adds the operations perspective — how teams audit for this using Kyverno, and why the default PSS warnings don't fail closed. They close on the broader lesson: policy-as-code needs to cover the full pod lifecycle, not just admission time. #Kubernetes #PodSecurityStandards #DevOps #CloudNative #ContainerSecurity #KubernetesSecurity #Kyverno #AdmissionController #Sidecar #InitContainer #EphemeralContainer #SecurityPolicy #PSS #RBACGap #Technology #FexingoBusiness #BusinessPodcast #DevOpsDaily Keep every episode free: buymeacoffee.com/fexingo
