Using JSON Output to Track and Log Flyway Migration Activity

There are many occasions when a developer needs to know the current version of a Flyway database, such as when generating a build script, creating a backup, or notifying a team of version changes. Flyway's JSON output now makes it easier to retrieve this and any other data needed for running post-migration tasks. This article demonstrates how to use this output to send simple, human-readable notifications of Flyway activity, helping developers stay informed about changes that could impact their work.

Using Bash with Flyway

If you're using a Linux-based operating system, Bash is the obvious choice of scripting language for Flyway. This article demos the basics of dealing with credentials in team-based database development, when using 'traditional' flyway.conf files, and how to save and parse the JSON output of Flyway commands, for example to retrieve the current schema version. It provides a full automation example that will allow a team to maintain several copies of a database, one per development branch, from a Flyway project. Read more

Using Flyway as a Multi-Database Migration System

Flyway can scale easily to enterprise-scale database systems, even if they involve a mix of relational database systems, are cloud-based, containerized or involve complex authentication. This article demonstrates how we can use Flyway Teams to do a single-batch, multi-database migration, comprising SQL Server, Oracle Cloud, PostgreSQL, MySQL and SQLite databases. Read more

This article demonstrates how to use PowerShell to fetch your login credentials from Windows Credential Manager and pipe them securely to Flyway without ever saving them in any form, such as in a file or environment variable. Read more

Pipelining Configuration Information Securely to Flyway

This article demonstrates two techniques for allowing Flyway to read extra configuration information from a secure location, possibly encrypted. The first technique pipes the contents of the config file to flyway via STDIN, and the second uses PowerShell splatting. This makes it much simpler to use Flyway to manage multiple development copies of a database using role-base security. Read more

Using Windows Security and Encryption with Flyway

This article describes a simple technique that will allow you to use Flyway securely, even in cases where more than just the login credentials need to be protected. It uses a PowerShell technique that converts an encrypted Flyway configuration file into an array of parameters that Flyway can read just as if you were typing them in. Read more

A Simple Example of Flyway Development using GitHub Branching

This article demonstrates one way to do branch-based database development with Flyway, using GitHub to manage the branches and Flyway configuration files to allow Flyway to switch smoothly between databases, when we move between branches in GitHub. Read more
