What will be deployed?

Before we deploy anything, we must provide everything that will be deployed. For this, we will deploy the JAR of our API module. The JAR is a result of application building. The first thing we will do is prepare our application for release. We will change our port from 9000 to 80. Open the application.properties file and make the following changes:

spring.application.name= journaler 
server.port= 80 
logging.level.root=INFO 
logging.level.com.journaler.api=DEBUG 
logging.level.org.springframework.jdbc=ERROR 
 
endpoints.health.enabled=true 
endpoints.trace.enabled=true 
endpoints.info.enabled=true 
endpoints.metrics.enabled=true 
 
spring.datasource.url=jdbc:mysql://localhost/journaler_api?useSSL=false&useUnicode=true&characterEncoding=utf-8 
spring.datasource.username=root 
spring.datasource.password=localInstance2017 
spring.datasource.tomcat.test-on-borrow=true 
spring.datasource.tomcat.validation-interval=30000
