-The example above shows how an Argo CD Application can be configured so it will ignore the `spec.replicas` field from the desired state (git) during the sync stage. This is achieve by calculating and pre-patching the desired state before applying it in the cluster. Note that the `RespectIgnoreDifferences` sync option is only effective when the resource is already created in the cluster. If the Application is being created and no live state exists, the desired state is applied as-is.
