+## Лабораторная работа №3, ПИбд-42 Тепечин Кирилл
+
+### Сервисы
+* `opop-service`
+* `document-service`
+
+### Синхронный обмен между микросервисами
+Синхронное взаимодействие осуществляется через `RestTemplate`
+
+Пример взаимодействия:
+
+````java
+restTemplate.getForObject(URL+ opopDto.getDocumentId(), DocumentInfo.class)
+````
+
+### Докерфайлы
+
+````dockerfile
+FROM eclipse-temurin:17-jdk-alpine
+VOLUME /tmp
+ARG JAR_FILE
+COPY ${JAR_FILE} app.jar
+ENTRYPOINT ["java","-jar","/app.jar"]
