Learn-MySQL

A project to get learned on MySQL, now using MariaDB, Flyway for the migrations, Python to access the DB programmitcally, and unittest framework.

Docker

Using docker compose to run a MariaDB server. Initial data data is done via flyway as are subsequent migration

The docker compose file creates a volume for database persistence. It can optionally be deleted when stopping the DB.

Initial Run

Start the database server

$ docker-compose up learn-mysql -d

Start the database client

$ docker run --network learn-mysql_learn-mysql -it --rm --name learn-mysql-client mariadb:10.3 mysql -hlearn-mysql_learn-mysql_1 -uroot -plearn

Create the classicmodels database

MariaDB [(none)]> CREATE DATABASE classicmodels;

Run flyway to create and fill the tables

$ docker-compose up learn-mysql-flyway

Subsequent Runs

Stopping the server

$ docker-compose down

This stops the server but keeps the persistent storage volume. To remove the volume and start fresh do:

$ docker-compose down --volumes

Testing

You can hack around in main.py or add the code to a unit test framework:

$  python tests/tests.py
