  # Step 2 of the ES 8 → 9 migration: official Elastic image reading the same
  # data volume that Bitnami ES 8.18 wrote. Two compatibility issues are
  # handled here, mirroring the prod k8s manifest:
  #   1. UID: Bitnami runs as 1001, official ES 9 runs as 1000. The init
  #      container chowns the volume once before ES starts.
  #   2. Data path: Bitnami stores at /bitnami/elasticsearch/data; we keep
  #      that path via the path.data env so ES 9 reads existing indexes
  #      without a move/copy.
  # The analysis-phonetic plugin (auto-installed by Bitnami via env) is
  # installed by the official image via the command wrapper at boot.
