In Container deployments I should be able to set my Java Options from the helm chart values file

Currently java options seem to be set in the statefulset.yaml file (this example is for agent relays, but the idea is for agents, relays and servers).

Currently I see this:

- name: JDK_JAVA_OPTIONS
value: "-Dcom.redhat.fips=false -XX:MaxRAMPercentage={{ .Values.javaContainerOptions.maxRAMPercentage | default 70 }} -XX:ActiveProcessorCount={{ .Values.javaContainerOptions.activeProcessorCount | default 2 }}"

- name: JAVA_TOOL_OPTIONS
value: "-Dcom.redhat.fips=false -XX:MaxRAMPercentage={{ .Values.javaContainerOptions.maxRAMPercentage | default 70 }} -XX:ActiveProcessorCount={{ .Values.javaContainerOptions.activeProcessorCount | default 2 }

In addition to the java options, I need to set some values in the environment for Java to help with performance. This is what I have had to change in the yaml file:

env:
{{- range .Values.trav.statefulset.env }}
- name: {{ .name }}
value: {{ .value | quote }}
{{- end }}
- name: JDK_JAVA_OPTIONS
value: {{ concat (list "-Dcom.redhat.fips=false") .Values.trav.statefulset.java.options | join " " | quote }}
- name: JAVA_TOOL_OPTIONS
value: {{ concat (list "-Dcom.redhat.fips=false") .Values.trav.statefulset.java.options | join " " | quote }}

Here is my values file to work with this:


statefulset:
env:
- name: JAVA_HOME
value: "/usr/lib/jvm/java-11-openjdk-11.0.25.0.9-7.el9.x86_64"
- name: LANG
value: "en_US.UTF-8"
- name: LC_ALL
value: "en_US.UTF-8"
java:
options:
- "-XX:-UsePerfData"
- "-Djava.net.preferIPv4Stack=true"
- "-Djava.security.egd=file:/dev/./urandom"
- "-XX:MaxRAMPercentage=70"
- "-XX:ActiveProcessorCount=2"

    We plan to deliver this for you in our 8.2.2.3 release and beyond. Moving this to the 'In development' state.

    My understanding following a conversation with our development team is that you only need to set some JAVA_OPTIONS. Our developer said we should be able to support adding a new helm value where you can specify JAVA_OPTIONS to be added / prepended (not replace) the options we set. I will check with the dev team for the latest information and update you.

    We are going to create a discussion topic for this request for review by our development team next week in our back2design sessions. I am moving this to the 'Under review' state.
