A PostgreSQL database running in a Docker container. If you have an older version of Docker that does not have Compose V2, substitute the docker compose commands with docker-compose.
See the init.sql file for the data structure and content.
To create and run the database container, run in this folder:
docker compose up -d
This will build the image (if it does not exist) and run a container named population_db in the background.
The database can be then accessed at postgres://postgres@127.0.0.1/population.
If you want to access the database from another Docker container, you need to create a network (docker network create <networkName>) and attach both containers to it (docker network connect <networkName> <containerName>). Then the database can be accessed at postgres://postgres@population_db/population.
(To stop the container, run: docker compose stop)
