Hi Peter, Environment variables should be used for this purpose. Exactly how this is done might vary a bit depending on your preference/practice configuration method.
What are you using now for the database configuration? NetBeans will allow you to set the environment variables which would also be set for the container (via Kubernetes in your case). Albeit a slightly different direction, we tend to do a good bit of Spring Boot which in addition to being Tomcat based and typically includes Hibernate, has, what I believe, is a (nice) opinionated way of doing such configurations. For Spring Boot, an application.properties file (in src/main/resources) might contain something like this: spring.datasource.url = jdbc:mysql://localhost:3306/mydatabase?useSSL=false and the SPRING_DATABASE_URL environment variable would override the above value if provided at runtime (via NetBeans, Docker, Kubernetes, etc.) but this example only scratches the surface with the amount of flexibility you actually have. Environment variables can also be included in the properties file. The concept of profiles is also available. The combination of NetBeans and Spring Boot is, for us, an excellent choice for local (database) development but we also leverage the Kubernetes which is part of Docker for Desktop (Windows and MacOS) to more closely emulate our runtime environment.
