Edit CATALINA_OPTS for registry.access.redhat.com/jboss-webserver-3/webserver30-tomcat8-openshift:1.2-12



Hi,


We are deploying .war files in a tomcat container on OpenShift.

This is our base image:

registry.access.redhat.com/jboss-webserver-3/webserver30-tomcat8-openshift:1.2-12


Our Dockerfile looks just like this:

+FROM registry.access.redhat.com/jboss-webserver-3/webserver30-tomcat8-openshift:1.2-12
 MAINTAINER xxx
 COPY apps/ /deployments/
 COPY conf/ /toolConfig/

How can we edit + see the CATALINA_OPTS of our Container? (env var or in dockerfile).

echo $CATALINA_OPTS gives me -Djava.security.egd=file:/dev/./urandom which is an unreadable file.


I'm also seeing some Catalina vars when the container (pod) is starting but nothing about the heapsize etc.

We need to do something like export CATALINA_OPTS="-Xms512M -Xmx1024MB"



Thanks!
