docker 出错（找不到我导出的模块），运行 npm 启动时没有问题

Question

Error: Cannot find module '../controllers/thermostatLogic'

Here is my dockerfile

FROM node:10-alpine
LABEL version="1.02"
RUN mkdir -p /app/node_modules && chown -R node:node /app
USER node
WORKDIR /app
COPY . /app
RUN npm install
RUN npm audit fix
RUN ls
RUN cd ./controllers && ls
RUN mkdir uploads &&\
cd uploads &&\
touch uploadedFile.csv
RUN cd ..
RUN ls
CMD npm start
EXPOSE 1000

I run the docker build -t hvacdoctor. command and then. When it runs the ls command it returns:

This all works with npm install & npm start without an error OUT of docker but why is this an issue within it?

I've tried a few different methods (git clone is out though because i need SSO for that etc)

These are the install instructions
1) download bash / node
2) create a folder called uploads and a file called uploadedFile.csv -make sure the file is in the folder.
3) npm install 
4) npm start

Edit - here is a screenshot of the current folder structure.

Thoughts?

Edit - it was suggested I run the program with the following docker-compose.yml

node-app:
  container_name: node-app
  image: node:latest
  restart: always
  volumes:
   - ./:/home/node/app
  working_dir: /home/node/app
  ports:
   - 4000:4000
  networks:
   - main-network
  command: "tail -f /dev/null && npm start"


Changed package.json

"main": "index.js",
"scripts": {
  "preinstall": "npm i nodemon -g",
  "start": "nodemon index.js",
}

^^ WITH this suggested start script nodemon starts index.js recursively - if I remove nodemon from the command it cannot find index.js. - I will likely edit this as it is in the routes folder to start as routes/index.js

ALSO to add clarity - previously I did not work with nodemon - I was running NPM start to start my project if that makes a difference (ie I can git clone and run npm install && npm start and it will work.

Try the below docker configuration for a node application. It will work for you.

 node-app:
  container_name: node-app
  image: node:latest
  restart: always
  volumes:
   - ./:/home/node/app
  working_dir: /home/node/app
  ports:
   - 4000:4000
  networks:
   - main-network
  command: "tail -f /dev/null && npm start"

Here below is package.json

"main": "index.js",
"scripts": {
  "preinstall": "npm i nodemon -g",
  "start": "nodemon index.js",
}

Turned out it could not find it as my mac is not type sensitive but ubuntu is. Standardizing my file names fixed it.

This dockerfile worked fine

FROM node:12.14.0-alpine
LABEL version="1.02"

#create working directories etc.
RUN mkdir -p /app

# Create a /App Directory to install the application in
WORKDIR /app

# Copy all files from the main project to the container
COPY . /app/

RUN npm install
# COPY package*.json ./app/
# RUN npm install
# Standard npm commands
## DELETE THE FOLLOWING WHEN DOCKER CONTAINER IS FIXED
RUN cd node_modules

# create an uploads directory , go into it and add a placeholder file to avoid bug.
RUN mkdir uploads
RUN touch uploads/uploadedFile.csv
#go back into root folder
# RUN cd ..
# RUN ls

# start project and expose port 3000 as localhost
CMD node ./bin/www
EXPOSE 3000
