The diffing customization can be configured for single or multiple application resources or at a system level. ArgoCD also has a solution for this and this gets explained in their documentation. configuring ignore differences at the system level. For applications containing thousands of objects this takes quite a long time and puts undue pressure on the api server. Fortunately we can do just that using the ignoreDifferences stanza of an Application spec. The example below shows how this can be achieved: apiVersion: argoproj.io . Without this either declared in the Application manifest or passed in the CLI via --sync-option CreateNamespace=true, the Application will fail to sync if the namespace doesn't exist. Unable to ignore differences in metadata annotations, configure kubedb argo application to ignore differences. By default, Argo CD uses the ignoreDifferences config just for computing the diff between the live and desired state which defines if the application is synced or not. However during the sync stage, the desired state is applied as-is. More information about those policies could be found here. By combining ArgoCD and Kyverno, we can declare policies using standard Kubernetes manifests in a git repository and get them applied to Kubernetes clusters automatically. Examples of this are kubernetes types which uses RawExtension, such as ServiceCatalog. In order to make ArgoCD happy, we need to ignore the generated rules. Why typically people don't use biases in attention mechanism?
