How to setup

Installing node_modules

1. Assuming you have already installed npm, in the folder where package.json is located, do npm install

Building the app image

1. In the folder with Dockerfile do sudo docker build -t my-app:1.0 .

2. Make sure there were no errors and you have both images(node and my-app), do sudo docker images

Launching containers

1. In the folder with docker-compose.yaml do sudo docker-compose -f docker-compose.yaml up

2. Wait for everything to download

3. Try to access both the app and the database - open a browser and type localhost:8080 and localhost:3000

4. Try editing and saving any info at localhost:3000 and then check if MongoDB created new volume and saved edited info

Troubleshooting

1. If you don't see MongoDB create a new volume, try sudo docker-compose -f docker-compose.yaml restart

2. This site can’t be reached when connecting to localhost:3000, make sure you did npm install and have node_modules folder within the app folder
