Using Oracle Database with Docker for Spring Boot Integration Testing
Introduction Testing against the same database you use in production is crucial for catching environment-specific bugs early. However, setting up Oracle locally has traditionally been painful—complex licensing, heavy resource requirements, and tedious configuration. Enter Oracle Free (formerly Oracle XE) with Docker. Oracle now provides lightweight, free Docker images that make local Oracle development surprisingly easy. Combined with Spring Boot’s Docker Compose support, you can spin up a real Oracle database automatically when your application starts.
