@ -36,15 +36,17 @@ In its default configuration, Petclinic uses an in-memory database (H2) which
gets populated at startup with data. The h2 console is automatically exposed at `http://localhost:8080/h2-console`
and it is possible to inspect the content of the database using the `jdbc:h2:mem:testdb` url.
A similar setup is provided for MySql in case a persistent database configuration is needed. Note that whenever the database type is changed, the app needs to be run with a different profile: `spring.profiles.active=mysql` for MySql.
A similar setup is provided for MySQL and PostgreSQL in case a persistent database configuration is needed. Note that whenever the database type is changed, the app needs to be run with a different profile: `spring.profiles.active=mysql` for MySQL or `spring.profiles.active=postgres` for PostgreSQL.

===============================================================================
=== 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.
