This project provides a method to seed a postgres schema using flyway as part of a circle ci build.

To use, zip up your flyway project into a file named schema.zip, and place it in this directory prior to doing your docker build. The docker build will unzip it into /opt/schema, and the script that invokes flyway assumes the migration directory is in /opt/schema/db.

When running in a Circle CI 2.0 build job, if postgres is run as a container in the build, it will be available from this container on localhost.

You will need to provide the DB_HOST, DB_PORT, USER, PASSWORD, and URL environment variables. DB_HOST and DB_PORT are used as inputs to nc for determining when postgres is available, and the rest are used as flyway inputs.

Below is a snipped from flyway config showing how it fits into a build.
