Can't access Jolokia HTTP endpoint in Kubernetes

I've got a super simple Java Kubernetes Tomcat application running inside of Kubernetes that I instrumented with the JVM Jolokia agent running on minikube. I'm trying to configure my Kubernetes deployment so I can access the Jolokia endpoint outside of the container. When I try to access the endpoint at http://127.0.0.1/jolokia/version from outside the container on my minikube IP I get a connection refused.

I've set the Jolokia agent via the CATALINA_OPTS variable and set it run on port 8778 and exposed 8778 in my Dockerfile. I've logged into the container and can confirm I can access the Jolokia agent as long as I'm inside the container.

FROM tomcat:8.0-alpine

ADD sample.war /usr/local/tomcat/webapps/
#ADD jolokia.war /usr/local/tomcat/webapps/

RUN mkdir /home/jolokia/
ADD jolokia-jvm-1.7.1.jar /home/jolokia/javaagent.jar
ENV CATALINA_OPTS="$CATALINA_OPTS -javaagent:/home/jolokia/javaagent.jar=port=8778"
RUN apk --no-cache add curl
EXPOSE 8080
EXPOSE 8778
CMD ["catalina.sh", "run"]

Next in my Kube deployment I specify that I set a nodePort to map 8778 to port 30087 however; when I pull my minikube IP and access it via http://minikube-ip:30087/jolokia/version, I keep getting connections refused. Here's my deployment:

        ports:
        - containerPort: 8080
        - containerPort: 8778

Jolokia agent works inside of my container, but how do I access it outside of the container?

I needed to set the Jolokia agent host to 0.0.0.0 as it wasn't using the right IP within the CATALINA_OPTS variable.

ENV CATALINA_OPTS="$CATALINA_OPTS javaagent:/home/jolokia/javaagent.jar=port=8778,host=0.0.0.0"
