  bash deploy.sh [--load-images] [--push-images] [--image-registry-prefix PREFIX] [--config|--defaults] k8s [K8s 部署选项]

USAGE
    if [ "$DEPLOY_WRAPPER_DEFAULT_CONFIG_MODE" = "defaults" ]; then
      cat <<'USAGE'
此离线包入口默认复用保存配置或内置默认值部署，不进入交互界面。
添加 --config 可进入交互式部署配置界面。
实现：deploy/deploy.sh

USAGE
    else
      cat <<'USAGE'
此根入口只转发到目标专用部署脚本。
实现：deploy/deploy.sh

USAGE
    fi
    cat <<'USAGE'
选项：
  --load-images    部署前从 ./images 加载 Docker 镜像 tar 文件。
                   默认关闭。
  --push-images    部署前调用 push-images.sh 推送镜像。
  --image-registry-prefix PREFIX
                   镜像仓库前缀，例如 registry.example.com/nexent。
                   使用 --push-images 且未传入时会交互询问。
  --config         进入交互式部署配置界面。
  --defaults       复用保存配置或内置默认值，跳过交互界面。

Usage:
  bash deploy.sh [--load-images] [--push-images] [--image-registry-prefix PREFIX] [--config|--defaults] docker [docker deploy options]
  bash deploy.sh [--load-images] [--push-images] [--image-registry-prefix PREFIX] [--config|--defaults] k8s [k8s deploy options]

USAGE
  if [ "$DEPLOY_WRAPPER_DEFAULT_CONFIG_MODE" = "defaults" ]; then
    cat <<'USAGE'
This offline entrypoint deploys with saved configuration or built-in defaults by default.
Add --config to open the interactive deployment configuration.
Implementation: deploy/deploy.sh

USAGE
  else
    cat <<'USAGE'
This root entrypoint only forwards to the target-specific deploy script.
Implementation: deploy/deploy.sh

USAGE
  fi
  cat <<'USAGE'
Options:
  --load-images    Load Docker image tar files from ./images before deploying.
                   Defaults to off.
  --push-images    Run push-images.sh before deploying.
  --image-registry-prefix PREFIX
                   Image registry prefix, e.g. registry.example.com/nexent.
                   Prompts when --push-images is used and no prefix is provided.
  --config         Open the interactive deployment configuration.
  --defaults       Use saved configuration or built-in defaults and skip TUI.
