Welcome in my Readme file!

1. Deployment requirements:

• Have a Linux OS
• Have Docker and Docker Compose

2. Application overview : This is an app using Flash and it's connected to a PostgreSQL database. The only thing that the app do is show a little text in a web page.

3. Virtual networks and named volumes used

• Virtual network: my app uses a Docker network who makes the communication between web app and the database possible.
• Named volume: I have one persistent volume "postgres_data" for store the database files so I have the data when the cainer is restarted.

4. Container configuration : It uses 2 containers:

• The web container (Flash): the exposes port is 5000, and I use my_app_network as network.
• The database container (PostgreSQL): there are 3 environment variables (user, password and database); a persistent volume (postgres_data) and it uses my_app_network as network.

5. Instructions for the deployment :

• First, you need to clone the repository and go on the project directory

• Second, you need to start the files with Docker-compose (docker-compose up -d --build) It's now running!

• For stopping the app but without losing the data, you need to do (docker-compose down)

• If you want to remove everyhting, add -v at the end (docker-composr down -v)

6. Instructions for accessing the app :

• Go to http://localhost:5000 so see the page
• And we can see that the database is connected if we go to :http://localhost:5000/db-test

Thanks for reading!
