+#### TLS certificate rotation
+
+If the exporter uses TLS certificates that are mounted as a secret in the container file system like the example
+[above](#tls-authentication-and-encryption), the exporter will not automatically apply them when the TLS certificates
+are rotated. Such a rotation can be for example triggered, when the [cert-manager](https://cert-manager.io/) issues new
+TLS certificates before expiring.
+
+Until the exporter does not support rotating TLS certificate a workaround can be applied. For example stakater's
+[reloader](https://github.com/stakater/Reloader) controller can be used to trigger a rolling update. The following
+annotation must be added to instruct the reloader controller to trigger a rolling update, when the mounted configMaps
+and secrets have been changed.
+
+```yaml
+deployment:
+  annotations:
+    reloader.stakater.com/auto: "true"
+```
+
+Instead of triggering a rolling update for configMap and secret resources, this action can also be defined for
+individual items. For example, when the secret named `prometheus-postgresql-exporter-http` is mounted and the reloader
+controller should only listen for changes of this secret:
+
+```yaml
+deployment:
+  annotations:
+    secret.reloader.stakater.com/reload: "prometheus-postgresql-exporter-http"

+## ArgoCD
+
+### Daily execution of rolling updates
+
+The behavior whereby ArgoCD triggers a rolling update even though nothing appears to have changed often occurs in
+connection with the helm concept `checksum/secret`, `checksum/configmap` or more generally, [Automatically Roll
+Deployments](https://helm.sh/docs/howto/charts_tips_and_tricks/#automatically-roll-deployments).
+
+The problem with combining this concept with ArgoCD is that ArgoCD re-renders the Helm chart every time. Even if the
+content of the config map or secret has not changed, there may be minimal differences (e.g., whitespace, chart version,
+Helm render order, different timestamps).
+
+This changes the SHA256 hash, Argo sees a drift and trigger a rolling update of the deployment. Among other things, this
+can lead to unnecessary notifications from ArgoCD.
