Download DB dump from https://github.com/dhis2/dhis2-demo-db/blob/master/sierra-leone/2.32/dhis2-db-sierra-leone.sql.gz Unzip and place under db directory

Then you can docker-compose up and visit http://localhost:8085/ (admin / district)

docker-compose down and docker-compose up if something went wrong.

Yo probably want to include an environment in your webapp so it waits for the DB to be prepopulated. And also a dependency.

        environment:
            - WAIT_FOR_DB_CONTAINER=db:5432 -t 0

            - db
