The first workflow, `build-and-push.yml`, builds and stores a container image from the `/db` directory which will load data from a GCS bucket at startup. The second worklow, `test-migration.yml`, detects when migration changes in pull requests exist and runs the database container with a full copy of production data against which migrations can be tested.

The success or failure of the migration is added as a comment to the pull request. ## Assumptions -* This app assumes there is a `pg_dump` from PostgreSQL stored in a Google Cloud Storage (GCS) bucket. * This is a Node app and uses [Sequelize](https://sequelize.org/) to run the database migration. * The workflow variable `DB_BACKUP_URL` needs to be pointed at the bucket containing the backup. * You must have [Docker](https://www.docker.com/) installed to run the app locally. -* This app loads the database backup into a PostgreSQL container when the workflow `test-migration` runs.
