I’m a newbie with Docker and I’m trying to start with NodeJS hosted in asphostportal.com so here is my question..<\/p>\n

I have this Dockerfile inside my project:<\/p>\n

FROM node:argon<\/p>\n

# Create app directory
\nRUN mkdir -p \/home\/Documents\/node-app
\nWORKDIR \/home\/Documents\/node-app<\/p>\n

# Install app dependencies
\nCOPY package.json \/home\/Documents\/node-app
\nRUN npm install<\/p>\n

# Bundle app source
\nCOPY . \/home\/Documents\/node-app<\/p>\n

EXPOSE 8080
\nCMD [“npm”, “start”]<\/p>\n

 <\/p>\n

When I run a container with<\/p>\n

docker run -d -p 49160:8080 node-container<\/p>\n

 <\/p>\n

it works fine..
\nBut when I try to map my host project with the container directory (<\/p>\n

docker run -p 49160:8080 -v ~\/Documentos\/nodeApp:\/home\/Documents\/node-app node-cont<\/p>\n

 <\/p>\n

) it doesn’t work.
\nThe error I get is:<\/p>\n

Code:<\/p>\n

Error: Cannot find module ‘express’<\/p>\n

 <\/p>\n

I’ve tried with other solutions from related questions but nothing seems to work for me (or I know.. I’m just too rookie with this)
