Worked on the CommunityToolkit/Aspire repository to enhance the reliability of Keycloak’s Postgres integration, focusing on backend development and database integration using C#. Addressed a critical issue where the JDBC connection used an incorrect database name by ensuring the JDBC URL construction now references the intended DatabaseName, particularly in environments with renamed or dynamic databases. Expanded test coverage to validate the behavior of environment variables and custom database names, using integration testing to prevent misconfigurations. These changes clarified the expectations for environment-variable mapping and connection setup, resulting in more robust and predictable Keycloak integration with Postgres in varied deployment scenarios.
