PYTHONPATH ENV 原在 Step2 前置,致其后所有层 cache miss,TA-Lib 步骤重编译触发
wget sourceforge 国内卡死(build_v3 卡 29min load0.04)。移到 COPY 代码后:Step1-19
(apt/TA-Lib/pip)与旧 build 相同→缓存命中跳过 wget,只 ENV+COPY 重跑(秒级)。
功能等价(PYTHONPATH 在镜像 env,spawn 子进程继承),仅层缓存优化。

build_v4 实证:Step5 TA-Lib Using cache(跳 wget)+镜像 ENV PYTHONPATH 固化
(docker exec 探针可见 /app:/app/vnpy_v4.4.0,修复前空)。
