This is a Python Flask application that greets users with a simple message.

The main objectives of this project were:

• To "dockerize" the application by providing an image and a configuration for running locally with Docker Compose.
• To provide a script that retrieves data from an API and performs basic parsing.
• To provide a reverse proxy configuration.

To achieve the above objectives, the following steps were taken:

• A Dockerfile was created to build and run the application.
• The application was modified to replace Hello, World! with an optional string set using an environment variable, and defaulting to Hello, World!.
• A docker-compose.yml file was provided to run the application and set a custom string using an environment variable.

This should result in the ability to navigate to http://localhost:5000/ and see the custom greeting.

A script was provided to parse the data returned from http://localhost:5000/data and create a file in a files/ sub-directory named <id>.txt with the name as the contents of the file. E.g. files/3fc4ccfe745870e2c0d99f71f30ff0656c8dedd41cc1d7d3d376b0dbe685e2f3.txt

Note: The SHA256 sum of each file's contents (<name>) should match the <id>.

A minimal reverse proxy configuration was provided for the application using Nginx. The nginx.conf file was used and ran from the same Docker Compose file as the application.

Here's a list of the files in this project:

• app.py: the Flask application code
• docker-compose.yml: the Docker Compose configuration file
• Dockerfile: the Dockerfile used to build the Docker image for the application
• files/: a directory where the parsed files are stored
• nginx.conf: the Nginx reverse proxy configuration file
• parse_and_create_files.py: the script to parse the data and create the files
• parse_data.py: the script to retrieve the data from the API
• README.md: the file you're reading right now
• requirements.txt: the Python packages required for the application to run
