gem-hunterNorthwind sample database for postgres
A simple sql script that will populate a database with the famous northwind example, adapted for postgres.
Use the provided sql file nortwhind.sql in order to populate your database.
https://www.docker.com/get-started
https://docs.docker.com/compose/install/
> docker-compose up ... ... Lots of messages... ... Creating network "northwind_psql_db" with driver "bridge" Creating volume "northwind_psql_db" with default driver Creating volume "northwind_psql_pgadmin" with default driver Creating pgadmin ... done Creating db ... done
Open another terminal window, and type:
> docker-compose exec db psql -U postgres -d northwind psql (13.2 (Debian 13.2-1.pgdg100+1)) Type "help" for help. northwind=# select * from us_states; state_id | state_name | state_abbr | state_region ----------+----------------------+------------+-------------- 1 | Alabama | AL | south 2 | Alaska | AK | north ...
Alternatively, you can launch bash, then psql:
docker-compose exec db /bin/bash # You are now inside the "db" docker container psql -U postgres northwind
The "db" docker exposes postgres on the port 55432. If you have psql on your path, you may connect to it via:
# Run this directly from your computer (this will connect to the docker db)
psql -U postgres northwind -p 55432Access to PgAdmin at the url: http://localhost:5050
Add a new server in PgAdmin:
Then, select database "northwind".
Stop the server that was launched by docker compose up via Ctrl-C, then remove the containers via:
docker-compose down
Your modifications to the postgres database(s)will be persisted in the postgresql_data docker volume, and can be retrieved once you restart docker compose up.
If you need to delete the database data, run docker-compose down -v (the database will then be repopulated from scratch when running docker-compose up).
If you need to upload any files into your db container, just copy and paste them to the files local folder. They will be available at the /files path inside the db container.
