Failed to bind Spring Boot port on Heroku

Question

I'm trying to deploy a Spring Boot application on Heroku with Docker. The build is successful both when building the .war file and the Docker image. I'm not entirely sure where the problem exists.

I have tried defining EXPOSE 80, ENV PORT=80 in my Dockerfile and that doesn't work either. I tried defining the port in my config file application-prod.yml, but that didn't work. What else should I look for here, is there something I missed with deploying on Heroku with Spring Boot?

The error message:

Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch

This is my Dockerfile:

FROM tomcat:jdk16-openjdk-slim

# Java options
ENV JAVA_TOOL_OPTIONS="-Xms100M -Xmx100M -Dspring.profiles.active=prod -Dserver.port=80"
ENV PORT=80

# Firebase Config
ENV GOOGLE_APPLICATION_CREDENTIALS=./src/main/resources/firebase.json

# War file for Tomcat
ARG WAR_FILE=/build/libs/mefit-0.0.1-SNAPSHOT.war
RUN rm -rf /usr/local/tomcat/webapps/*
COPY ${WAR_FILE} /usr/local/tomcat/webapps/ROOT.war

ENV CATALINA_OPTS="-Xms100M -Xmx100M"
EXPOSE 80
CMD ["catalina.sh", "run"]

This is the log from Heroku:

Can you show my your Spring boot propertie files? I would like to see if you tell spring boot that its' hosting port is depending on an environment variable.
