This app shows a simple user profile app set up using

• index.html with pure js and css styles
• nodejs backend with express module
• mongodb for data storage

All components are docker-based

//NOTE: Works on temporary container storage as volume not attached.

Part 1: With Docker

To start the application

Step 1: Create docker network

$ docker network create mongo-network

Step 2: start mongodb

$ docker run -d -p 27017:27017 -e MONGO_INITDB_ROOT_USERNAME=admin -e MONGO_INITDB_ROOT_PASSWORD=password --name mongodb --net mongo-network mongo

Step 3: start mongo-express

$ docker run -d -p 8081:8081 -e ME_CONFIG_MONGODB_ADMINUSERNAME=admin -e ME_CONFIG_MONGODB_ADMINPASSWORD=password --net mongo-network --name mongo-express -e ME_CONFIG_MONGODB_SERVER=mongodb mongo-express  

NOTE: creating docker-network in optional. You can start both containers in a default network. In this case, just emit --net flag in docker run command

Step 4: open mongo-express from browser

Link: http://localhost:8081

Step 5: create my-db database and users collection using mongo-express (mongo-db UI)

Step 6: Start your nodejs application locally - go to app directory of project

$ npm install 
$ node server.js

Step 7: NodeJS application is now running. View UI in browser at port 3000.

Link: http://localhost:3000

Part 2: With Docker Compose: part of Infrastructure as a Code (IaaC), provisioning and running containers over a default network using docker compose file.

To start the application

Step 1: start mongodb and mongo-express

$ docker-compose -f docker-compose.yaml up

You can access the mongo-express under localhost:8080 from your browser

Step 2: in mongo-express UI - create a new database "my-db"

Step 3: in mongo-express UI - create a new collection "users" in the database "my-db"

Step 4: start node server

$ npm install 
$ node server.js

Step 5: access the nodejs application from browser

http://localhost:3000

Using Dockerfile to build a docker image from the application:

$ docker build -t my-app:1.0 .

The dot "." at the end of the command denotes location of the Dockerfile.
