+## 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.
+
+To avoid this, the annotation with the shasum must be ignored. Below is a diff that adds the `Application` to ignore all
+annotations with the prefix `checksum`.
+
+```diff
+  apiVersion: argoproj.io/v1alpha1
+  kind: Application
+  spec:
++   ignoreDifferences:
