Currently the top of my docker image is this:
FROM tomcat:8-jre8
This docker image is consuming a ton of memory. Could that be because the incorrect version?

tomcat:8-jre8 is a very huge image. You can reduce image size significantly by using the alpine or slim version.
docker pull tomcat:8-jre8-alpine
Check the comparison 8-jre8 and 8-jre8-alpine tags below
Have a look at other available options: https://hub.docker.com/_/tomcat?tab=tags&page=1&name=8-jre8

Do you know where certs would go? /usr/lib/jvm/java-1.8.0-openjdk/jre/lib/security/cacerts – dropkick Jan 31 '20 at 17:12

@dropkick you can pass it in `vm` arguments while running the programming. `java MyClass -Djavax.net.ssl.trustStore="path to cacert file"` – Govinda Sakhare Jan 31 '20 at 17:18

Yea I was able to get this to work. But I guess something with my java/angular must be causing the high memory. Idk if you know much about what it could be? – dropkick Jan 31 '20 at 18:37

Not sure if, in your case, you must use Tommy but, if you just want a web server you may want to try using a jre8 image that uses jetty such as https://hub.docker.com/_/jetty or another good one is undertow. Basically TommyCAT is very big whereas Jetty or Undertow are smaller web servers. See if you can't update your FROM... line and try jetty or undertow and see if you get better memory usage.
