How can I create a Dockerfile that runs both my nodeJS server and also launches mongodb? All in the same container

I need to be able to run within the same container both: my nodejs server.js and mongodb.

I know it is possible to achieve this with docker-compose or with two separate containers but that is not an option here. I need both services running on the same container.

My Dockerfile is something like this:

FROM node:16
WORKDIR /usr/src/app
RUN apt-get update && apt-get install -y mongodb
COPY package.json ./
RUN npm install
COPY server.js public/ ./
EXPOSE 3000
EXPOSE 27017
CMD service mongodb start && node server.js

Then at some point my server.js needs to call the mongodb like this:

const uri = 'mongodb://172.0.0.1:27017';

However when I try to build my container I get:

E: Package 'mongodb' has no installation candidate

    I don’t know why would you want to do this, you can create two different Dockerfiles as well, but anyway.

    FROM node:16

# Install MongoDB
RUN apt-get update && 
    apt-get install -y wget gnupg && 
    wget -qO - https://www.mongodb.org/static/pgp/server-5.0.asc | apt-key add - && 
    echo "deb http://repo.mongodb.org/apt/debian buster/mongodb-org/5.0 main" | tee /etc/apt/sources.list.d/mongodb-org-5.0.list && 
    apt-get update && 
    apt-get install -y mongodb-org

WORKDIR /usr/src/app

COPY package.json ./
RUN npm install

COPY server.js public/ ./

EXPOSE 3000
EXPOSE 27017

CMD service mongod start && node server.js

    const uri = 'mongodb://localhost:27017';

    Not sure why you are trying to run both MongoDB and Application in same container, Anyway you can do it like this;

    FROM node:14

# Install MongoDB
RUN apt-get update 
    && apt-get install -y mongodb 

# Create a directory to hold the application code inside the image
WORKDIR /usr/src/app

# Copy the application code into the container at /usr/src/app
COPY . .

# Install npm packages
RUN npm install

EXPOSE 80

# Run mongod to start MongoDB and server.js with Node.js in the background
CMD mongod --fork --logpath /var/log/mongod.log && node server.js

    I’ve used mongoose NPM Package to connect to MongoDB,

    const mongoose = require('mongoose');

const mongoDBUri = 'mongodb://localhost:27017/mydatabase';

mongoose.connect(mongoDBUri, { useNewUrlParser: true, useUnifiedTopology: true });

const db = mongoose.connection;

db.on('error', console.error.bind(console, 'MongoDB connection error:'));
db.once('open', function() {
  console.log('Connected successfully to MongoDB');
});
