h2. The Roboconf application "Sample PVC"

Our PVC will:
...

To be highly available, all Petals components are duplicated at least twice. The PostgreSQL database should be also highly available, but to simplify the comprehension we will use only one instance of the database.

So at the definition of an empty PVC, we add the following Roboconf models:

PetalsSLPostgreSQL {
extends: PetalsSL;
# As SL are not supported by Roboconf because:
# - a SL export no configuration parameter
# - Roboconf is not able to manage local dependency
# We create a dummy exported variable and work with only one instance of Petals SE Activiti over all Petals containers
exports: present = true;
}

PetalsSEActiviti {
extends: PetalsSE;
# See comment on PetalsSLPostgreSQL
imports: PetalsSLPostgreSQL.present, ActivitiPgSQLDatabase.*;
