 # Copies the built plugin into the shared PVC so Headlamp picks it up.
-# The PVC must already be mounted on the CI runner at PLUGIN_VOLUME_PATH.
+# Uses a temporary Kubernetes pod to write to the PVC — the CI runner

 # Usage:
-#   scripts/deploy-plugin-via-volume.sh [plugin-volume-path]
+#   scripts/deploy-plugin-via-volume.sh
 #
 # Environment:
-#   PLUGIN_VOLUME_PATH  — mount point of the shared PVC (default: /mnt/headlamp-plugins)
 #   HEADLAMP_NAMESPACE  — namespace where Headlamp runs (default: kube-system)
 #   HEADLAMP_DEPLOY     — Headlamp deployment name (default: headlamp)
