Docker：错误：找不到模块/app/src/myapp.js

Question

When I build my container it seems to compile without any issues using:

docker build -t mycompany:1.0.0 .

When I check docker images the container displays.

When I try to host it locally using

docker run -p 8081:8081 -it mycompany:1.0.0

it returns an error saying:

Error: Cannot find module '/app/src/myapp.js

I feel like it shouldn't be this complicated. Here is my docker file:

FROM node:10
WORKDIR /app/src
COPY package.json /app
RUN npm install
COPY . /app
CMD node myapp.js
EXPOSE 8081

What is off?

Answer 1

You can see from the error itself , you are not copying anything inside /app/src. Your both COPY command's destination is /app. You need to place myapp.js inside /app/src.
