Docker /bin/bash: nodemon: command not found

I am trying to mount my working node code from my host into a docker container and run it using nodemon using docker-compose.
But container doesn’t seems to be able to find nodemon.
Note: My host machine does not has node or npm installed on it.

Here are the files in the root folder of my project (test). (This is only a rough draft)

  • How does docker's `net=host` setting work, and how can I do something similar with e.g. VirtualBox?
  • Assign one docker instance to each client
  • ssh key generation using dockerfile
  • docker-sync excludes are not excluded?
  • Docker port binding not working as expected
  • Trouble running UPNP on Docker
  • Dockerfile

    ADD . /test
    WORKDIR /test
    RUN make install
    CMD make run

    PWD:=$(shell pwd)
    export PATH:= $(PWD)/node_modules/.bin:$(PWD)/bin:$(PATH)

    install:
        @echo Running make install......
        @npm config set unsafe-perm true
        @npm install
    
    run:
        @echo Running make run......
    # Check if we are inside docker container
    ifdef DOCKER
        @echo We are dockerized!! :D
        @nodemon index.js
    else
        @nodemon index.js
    endif

      "license": "ISC"
    }
    

    index.js

    'use strict';
    
    var express = require('express');
    

    I build my image using docker-compose build. It finishes successfully.
    But when I try to run it using docker-compose up, I get:

    Creating test_app_1...
    Attaching to test_app_1
    app_1 | Running make run......
    app_1 | We are dockerized!! :D
    app_1 | /bin/bash: nodemon: command not found
    app_1 | make: *** [run] Error 127
    test_app_1 exited with code 2
    Gracefully stopping... (press Ctrl+C again to force)
    

    Can anyone please advice?

    The issue has been resolved. The issue boiled down to me not having node_modules in the mounted volume.

    Basically, while doing docker-compose build the image was build correctly with the actual code being added to the image and creating the node_modules folder by npm install in the project root. But with docker-compose up the code was being mounted in the project root and it was overriding the earlier added code including the newly created node_modules folder.

    So as a solution I compromised to install nodejs on my host and do a npm install on my host. So when the code my being mounted I still got my node_modules folder in my project root because it was also getting mounted from my host.

    Not a very elegant solution but since it is a development setup I am ready for the compromise. On production I would be setting up using docker build and docker run and won’t be using nodemon anyways.

    If anyone can suggest me a better solution I will be greatful.

    Thanks!!

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
