Node.js with MongoDB Docker App Demo

Node.js with MongoDB and Docker Demo

Application demo designed to show how Node.js and MongoDB can be run in Docker containers. The app uses Mongoose to create a simple database that stores Docker commands and examples.

Starting the Application with Docker Containers:

1. Install Docker Desktop

2. Open a command prompt.

3. Run the commands listed in node.dockerfile (see the comments at the top of the file).

4. Navigate to http://localhost:3000.

Starting the Application with Docker Compose

1. Install Docker Desktop

2. Open a command prompt at the root of the application's folder.

3. Run docker compose build

4. Run docker compose up

5. Open another command prompt and run docker compose ps -a and note the ID of the Node container

6. Run docker exec -it <nodeContainerID> sh (replace with the proper ID) to sh into the container

7. Run node dbSeeder.js to seed the MongoDB database

8. Type exit to leave the sh session

9. Navigate to http://localhost:3000 (http://192.168.99.100:3000 if using Docker Toolbox) in your browser to view the site. This assumes that's the IP assigned to VirtualBox - change if needed.

10. Run docker-compose down to stop the containers and remove them.

To run the app with Node.js and MongoDB (without Docker):

1. Install and start MongoDB (https://docs.mongodb.com/manual/administration/install-community/).

2. Install the LTS version of Node.js (http://nodejs.org).

3. Open config/config.development.json and adjust the host name to your MongoDB server name (localhost normally works if you're running locally).

4. Run npm install.

5. Run node dbSeeder.js to get the sample data loaded into MongoDB. Exit the command prompt.

6. Run npm start to start the server.

7. Navigate to http://localhost:3000 in your browser.
