randianb / db-migration

Platform agnostic database migration

Requirements

Docker

First time setup

Run docker-compose up oracle to start the oracle container. Warning: the container itself is more than 3Gb in size, and requires 6Gb of free space. Also, currently the init script is broken on Windows. You have to spin it up first on Mac, or Linux to initialise the DB. Then you can use those files to run the DB on Windows.

Migration

Once your DB is up and running, run docker-compose up flyway to immediately run the migration process. The container will look for SQL files in the sql/migration folder.

Kill oracle

Run docker kill oraclein your terminal.

Helpers
