Getting mongo bson error using Docker on Mongoose/Express - mongodb

Question

I'm working on a small test project and everything was working fine until I added date-logger "service" which uses mongoose.
I get the following error upon running docker-compose up --build:
Error: Cannot find module 'mongodb/node_modules/bson'
Require stack:
- /app/node_modules/mongoose/lib/drivers/node-mongodb-native/objectid.js
...
Everything else gets started and runs correctly, except for this service which immediately fails as soon as require('mongoose') is reached.
Here are some of the important files:
docker-compose.yml:
version: '3'
services:
postgres:
image: 'postgres:latest'
redis:
image: 'redis:latest'
api:
build:
dockerfile: Dockerfile.dev
context: ./server
volumes:
- /app/node_modules
- ./server:/app
environment:
- REDIS_HOST=${REDIS_HOST}
- REDIS_PORT=${REDIS_PORT}
- PG_USER=${PG_USER}
- PG_HOST=${PG_HOST}
- PG_DB=${PG_DB}
- PG_PASSWORD=${PG_PASSWORD}
- PG_PORT=${PG_PORT}
date-logger:
build:
dockerfile: Dockerfile.dev
context: ./date-logger
volumes:
- /app/node_modules
- ./date-logger:/app
environment:
- EXPRESS_PORT=${EXPRESS_PORT}

- "mongo"
client:
build:
dockerfile: Dockerfile.dev

worker:
build:
dockerfile: Dockerfile.dev

volumes:

nginx:

mongo:

container_name: mongo
Dockerfile.dev on date-logger
FROM node:alpine
WORKDIR '/app'
COPY ./package.json .

COPY . .
CMD ["npm", "run", "dev"]
package.json on date-logger:

}
index.js on date-logger:
let express = require('express');
let bodyParser = require('body-parser');
// This console.log works
console.log('date-logger hello ---');
// ****!!!! IT FAILS IMMEDIATELY ON THIS REQUIRE !!!****
let mongoose = require('mongoose');
let app = express();
app.use(
bodyParser.urlencoded({
extended: true
})
);
app.use(bodyParser.json());
mongoose.connect('mongodb://mongo/date-logger');
const ItemSchema = new mongoose.Schema({
value: {
type: String,
required: true
},
date: {
type: Date,
default: Date.now
}
});
Item = mongoose.model('item', ItemSchema);
var port = process.env.EXPRESS_PORT || 8080;
app.get('/', (req, res) => res.send('Hello World with Express'));
app.get('/date', (req, res) => res.send('data'));
app.get('/date/all', (req, res) => {
Item.find({}).exec().then(results => res.send(results))
});
app.post('/date/add', (req, res) => {
const newItem = new Item({
value: req.body.value
});
newItem.save().then(item => res.send('success'));
});
app.listen(port, function() {
console.log('Running RestHub on port ' + port);
});
I'm new to devops world so all/any help is super appreciated! Thanks!

Answer 1

I think your problem is related to mongoose and not docker,
check this issue

Answer 2

This is very old but I came across a similar problem recently (but using only docker, not docker-compose).
I solved the problem by removing package-lock.json from my .dockerignore file (it should have never been there at all).
And of course make sure you can run npm install in your local machine, try removing package-lock and node_modulues and running npm install again if you can't. And update any modules you can.
