#bundle build

#SERVER.JS in node-src folder
WORKDIR /sequentialbot/node-src
EXPOSE 3000
ENTRYPOINT ["node", "server.js"]
#run.py inside sequentialbot folder 
WORKDIR /sequentialbot
EXPOSE 9595
ENTRYPOINT [ "python3", "./run.py" ]

我已经写了这个docker文件来构建我的applicatio.my应用程序在python:3.5和node中。

使用以下文件创建使用此文件的docker镜像后，使用以下命令: docker run <image name>未指定端口或其他仅用于检查输出的内容

所以给我这样的错误:

python3: can't open file './run.py': [Errno 2] No such file or directory

我知道一些路径问题，但可以建议一些路径工作方式或可以共享一些引用 docker 文件。

您可以将ENTRYPOINT更改为此:

ENTRYPOINT [ "python3", "/sequentialbot/run.py" ]

据我所知，WORKDIR对于在构建期间运行的命令有效。 ENTRYPOINT命令作为容器启动的一部分运行。
