I have my Dockerfile and docker-compose.yml configured to start my two services – this is my postgres db and Spring Boot app.
Dockerfile:
FROM openjdk:8-jdk-alpine
ENV JAVA_HOME /usr/lib/jvm/java-8-openjdk-amd64/
RUN export JAVA_HOME
COPY ./init.dump /docker-entrypoint-initdb.d/
RUN chmod 0755 /docker-entrypoint-initdb.d/init.dump
COPY target/endlessblow-server-1.0-SNAPSHOT.jar /
COPY endless-blow-firebase.json /
EXPOSE 8000
CMD ["java", "-jar", "endlessblow-server-1.0-SNAPSHOT.jar"]
docker-compose.yml

Now, the problem is once the containers are starting and db container is started, the container with Spring Boot app still fails to be started due to this exception:
