# Worker Dockerfile - 分层缓存优化版
|
|
# 优化：基础依赖 + Worker大包预构建为基础镜像，业务构建仅叠加业务依赖
|
|
# 基础镜像：worker-base-builder / worker-base-runtime
|
|
# ============================================================
|
|
|
|
# ==================== Builder 阶段 ====================
|
|
# 从预构建的builder基础镜像开始，已经包含：
|
|
# - 编译工具 (gcc/g++/python3-dev/binutils)
|
|
# - requirements-base.txt 全部依赖
|
|
# - requirements-worker.txt 全部依赖 (numpy/scipy/opencv)
|
|
# - 预strip的.so文件
