From 570024013a84faa9bcf500f4a10548463ed1026c Mon Sep 17 00:00:00 2001 From: Steven Fitzpatrick Date: Wed, 13 May 2020 16:00:17 -0500 Subject: [PATCH] Fluentd: Attach uuid to fluentd config etc 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 }} # Output Configuration here {{- 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 [0] https://review.opendev.org/#/c/726880/ Change-Id: I3dce9e5c4eaf588569e8cc3e1ea3cf3bebd0c3c5 --- fluentd/templates/configmap-etc.yaml | 2 ++ 1 file changed, 2 insertions(+) diff --git a/fluentd/templates/configmap-etc.yaml b/fluentd/templates/configmap-etc.yaml index 4de7569fb..b297394dc 100644 --- a/fluentd/templates/configmap-etc.yaml +++ b/fluentd/templates/configmap-etc.yaml @@ -19,6 +19,8 @@ apiVersion: v1 kind: Secret metadata: name: {{ printf "%s-%s" $envAll.Release.Name "fluentd-etc" | quote }} + annotations: + {{ tuple $envAll | include "helm-toolkit.snippets.release_uuid" }} type: Opaque data: {{- include "helm-toolkit.snippets.values_template_renderer" (dict "envAll" $envAll "template" .Values.conf.fluentd.template "key" "fluent.conf" "format" "Secret") | indent 2 }}
