=============================================================================== === Spring PetClinic sample application - PostgreSQL Configuration === =============================================================================== -------------------------------------------------------------------------------- 1) Run the "docker-compose.yml" from the root of the project: $ docker-compose up ... spring-petclinic-postgres-1 | The files belonging to this database system will be owned by user "postgres". ... 2) Run the app with `spring.profiles.active=postgres` (e.g. as a System property via the command line, but any way that sets that property in a Spring Boot app should work). For example use mvn spring-boot:run -Dspring-boot.run.profiles=postgres To activate the profile on the command line.
