# =============================================================================
# Makefile for confidential-containers build system
# 版本: 1.0
#
# 功能说明:
# - 提供Makefile接口来构建机密容器相关组件
# - 支持模块化构建：kata-agent、initrd镜像、payload镜像、operator部署清单
# - 支持两种initrd构建模式：update（快速更新）和full（完整构建）
#
# 主要构建目标:
# - kata-agent: 构建kata-agent二进制文件
# - initrd: 构建initrd镜像（支持update/full模式）
# - payload-images: 构建payload相关容器镜像
# - coco-operator: 定制化coco-operator部署清单
#
# 使用方法:
# - 完整构建: make all
# - 分步构建: make <target_name>
# - 清理环境: make clean
# - 显示帮助: make help
