By tying the fluent condfiguration to the release, it will be re-rendered
if the release is upgraded. This is useful in combination with [0], allowing
powerful configuration updates using helm upgrade. For example
Values:
.Values.pod.env.fluentd.vars.OUTPUT_ENABLED: true
fluent.conf:
...
{{- if .Values.pod.env.fluentd.vars.OUTPUT_ENABLED }}
<match **>
# Output Configuration here
</match>
{{- end }}
To disable this output section, issue a helm upgrade command and set the
apprpriate value to false.
helm upgrade fluentd ./fluentd --set pod.env.fluentd.vars.OUTPUT_ENABLED=false
