Below is my dockerfile: When this is running in openshift it uses 8 gigs and maxes out the openshift server. Is the dockerfile my issue. This is running a multi module project with two jar servers and a war file project. So I am running this with the war file on a tomcat server as we do locally.

  • I guess this could be related to the Java 8 issue related to "RAM quotas" using Docker on a PaaS, so the following reference would be useful in this case: https://developers.redhat.com/blog/2017/03/14/java-inside-docker – ErikMD Jan 25 '20 at 00:14
  • Also you should merge all your consecutive `RUN` commands in a single one to reduce the number of layers and thereby the size of the image (see also: [Purpose of specifying several UNIX commands in a single RUN instruction in Dockerfile](https://stackoverflow.com/q/59535609/9164010)) – ErikMD Jan 25 '20 at 00:25
  • I have another java program running just a jar and it barely needs a gig. Does this have something to do with Tomcat? @ErikMD – dropkick Jan 25 '20 at 02:26
