# Wave 9-11 — GPU serving stack on worker-1 (4x Tesla V100 32GB).
#
# Ordering matters: device plugin must expose nvidia.com/gpu and the KServe CRDs
# must exist before any InferenceService is applied, hence three waves.
#
# NOTE the chart versions below are v-PREFIXED (v0.15.2, not 0.15.2) — that is
# how the KServe OCI tags are published; the unprefixed form 404s.
