All the connection properties are in application.properties and it runs as expected outside when running locally outside the image. My Dockerfile-

FROM openjdk:8-jdk-alpine
ARG JAR_FILE=target/*.jar
COPY ${JAR_FILE} app.jar
ENTRYPOINT ["java","-jar","/app.jar"]

JDBC dependencies-

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ojdbc7</artifactId>
    <version>1.0</version>
</dependency>

Application.properties

#DB Properties
database.datasources[0].jndi-name=jdbc/SubscriptionServicesDataSource
database.datasources[0].username=xxxUnameXXX //fake
database.datasources[0].password=xxxPassxxx //fake

When you say "runs as expected outside when running locally outside the image" - do you run it as java -jar x.jar as well? — fg78nc, Jul 19 '20 at 12:42
@fg78nc - yes, when I run it as jar file it gets a connection. — Itsik Mauyhas, Jul 19 '20 at 17:16
