An extension of the Kotlin ktor starter sample that fetches data from a REST API and stores it in a DB.

1. Run docker-compose. This would start a postgres database in docker that can be connected to using the url localhost and port 555

   ./docker-compose up

2. If you are using a separate database from that provided with docker, run the create-database.sh script to create the necessary databases.

   ./databases/init-scripts/create-database.sh

3. You may need to make the script executable first

   chmod +x ./databases/init-scripts/create-database.sh

4. Set the environment variables. These values are typical if using the docker database

   export DB_USER=weather5028
   export DB_PASS=weather5028
   export DB_URL=localhost
   export DB_PORT=5555

5. Run the data-collector-server. This connects to the Weather Api, fetches the current weather info for London and stores it in the database

   ./gradlew a:data-collector-server:run

6. Connect to the database using pgAdmin and observe the new entry in the weather_snapshot table

   ./gradlew a:data-collector-server:run
