make INSTALL4J_ADD_VM_PARAMS available #3

In the official Dockerfile at https://github.com/sonatype/docker-nexus3/blob/master/Dockerfile#L76 the environment variable INSTALL4J_ADD_VM_PARAMS is set to

ENV INSTALL4J_ADD_VM_PARAMS="-Xms2703m -Xmx2703m -XX:MaxDirectMemorySize=2703m -Djava.util.prefs.userRoot=${NEXUS_DATA}/javaprefs"

and can be overwritten. This is not possible to overwrite from the secureimage but is required in our current setup.

Maybe add it? Thank you!

please also see the official image chef ruby (thanks to Carsten) which removes memory options from vmoptions

ruby_block "remove java memory settings from nexus.vmoptions" do
  block do
    file = Chef::Util::FileEdit.new(node['nexus_repository_manager']['nexus_home']['path'] + '/bin/nexus.vmoptions')
    file.search_file_delete_line(/^-Xms/)
    file.search_file_delete_line(/^-Xmx/)
    file.search_file_delete_line(/^-XX:MaxDirectMemorySize/)
    file.write_file
  end
end
