From dcca9b82c6778e166f7b86c6012435e998d6f8d3 Mon Sep 17 00:00:00 2001 From: Pierluigi Lenoci Date: Tue, 9 Jun 2026 20:49:47 +0200 Subject: [PATCH 1/3] feat: add tpl support for sessionStorage.redis.existingSecret Wrap the existingSecret field with tpl() in deployment.yaml so that Helm template expressions (e.g. '{{ .Release.Name }}-redis-secret') are evaluated at render time. This allows users to derive the secret name dynamically when oauth2-proxy is deployed as a subchart alongside operators that generate Redis secrets with structured names. Applied to both the standalone/cluster password secretKeyRef and the sentinel password secretKeyRef (which falls back to the base existingSecret when no sentinel-specific one is set).
