Running the application locally

To run the application locally, you need to start a local PosgreSQL instance. For example, you can use Docker as follows:

docker run --name some-postgres -e POSTGRES_USER=user -e POSTGRES_PASSWORD=password -e POSTGRES_DB=my_data -p 5432:5432 -d postgres

By default (for local development) the application uses:

• localhost as host
• 5432 as port
• user as username
• password as password
• my_data as database name

Then run the application using: mvn compile vertx:run. The application runs on: http://localhost:8080.
