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"
