DVD rental database to test purposes

test-db-pg-dvdrental

PostgreSQL DVD Rental database very useful to test purposes and playing with queries.

The idea was to create Docker image containing ready to use database example with sample data. I used sample database from PostgreSQL Tutorial and created Dockerfile to run postgres and restore db from backup.

Building docker image

First of all we have to build docker image. We can do it by execute:

docker build -t pg_dvdrental .

Docker will download all needed dependencies and build image with name "pg_dvdrental". We can check it by execute:

docker images

Running docker container

To run created image we have to execute "docker run" like this:

docker run -p 5433:5432 --name dvdrental -d pg_dvdrental

Docker will run container with name "dvdrental", based on image "pg_dvdrental" and it will expose containers port 5432 on localhost port 5433.

Connect to database

Now we can connect to our database. First we need credentials:

Database name: dvdrental
Database user: dvdrental
Database password: dvdrental

So lets check it using "docker" and "psql":

docker run -it --rm --link dvdrental:postgres postgres psql -h postgres -U dvdrental -d dvdrental

After put password ("dvdrental" to remind) we are connected to database and we can do queries. Let's check actors:

SELECT * FROM actor WHERE first_name ilike 'Kevin';
