The UPS has a bunch of System properties to tweak and configure some settings.

The are discussed here:
https://github.com/aerogear/aerogear.org/blob/master/docs/unifiedpush/ups_userguide/server-installation_properties.asciidoc#system-properties-for-the-unifiedpush-server

Setting these properties on bare-metal / on-prem. installations is easy, as one appends them when booting the WildFly server, such as:

./bin/standalone.sh -c standalone-full.xml -Dups.realm.name=aerogear -Dups.auth.server.url=http://keycloak.com:80/auth -b 0.0.0.0

In a cloud native world, this is not working. We need to make them work as ENV_VAR as well. So that a cn deployment can be simply altered by defining the actual ENV VAR

*NOTE*

The above two properties are not yet described in the doc:

• ups.realm.name=the realm for ups
• ups.auth.server.url = full-qualified URL of the Keycloak server location
