+
+Zeby spakowac apke do `jara` wystarcza dwie komendy
+
+```
+cd restservice
+mvn clean package spring-boot:repackage
+
+```
+
+Utworzony zostanie jar w `restservice/target/restservice-1.0-SNAPSHOT.jar`. Oczywiscie zeby jar zadzialal kontenery dockerowe musza byc odpalone (lub baza danych na serwerze jesli zmienialismy propertisy z localhost)
