Examining the managedFields above, we can see that the rollouts-controller manager owns some fields in the Rollout resource. using PrunePropagationPolicy sync option. respect ignore differences: argocd , . Below you can find details about each available Sync Option: You may wish to prevent an object from being pruned: In the UI, the pod will simply appear as out-of-sync: The sync-status panel shows that pruning was skipped, and why: The app will be out of sync if Argo CD expects a resource to be pruned. Used together with --local allows setting the repository root (default "/"), --refresh Refresh application data when retrieving, --revision string Compare live app to a particular revision, --server-side-generate Used with --local, this will send your manifests to the server for diffing, --auth-token string Authentication token, --client-crt string Client certificate file, --client-crt-key string Client certificate key file, --config string Path to Argo CD config (default "/home/user/.config/argocd/config"), --core If set to true then CLI talks directly to Kubernetes instead of talking to Argo CD API server. argocd app diff APPNAME [flags] Most of the Sync Options are configured in the Application resource spec.syncPolicy.syncOptions attribute. The propagation policy can be controlled The sync was performed (with pruning disabled), and there are resources which need to be deleted. The ultimate solution of this problem is to ignore the whole object-kind (in my case the Tekton PipelineRun) at instance-level of our ArgoCD instance! The diffing customization feature allows users to configure how ArgoCD behaves during the diff stage which is the step that verifies if an Application is synced or not.

This causes a conflict between the desired and live states that can lead to undesirable behavior. For applications containing thousands of objects this takes quite a long time and puts undue pressure on the api server. This overrides the ARGOCD_REPOSERVER_IMAGE environment variable.

This has to do with the fact that secrets often contain sensitive information like passwords or tokens, and these secrets are only encoded. Now it is possible to leverage the managedFields metadata to instruct ArgoCD about trusted managers and automatically ignore any fields owned by them. We can configure the ArgoCD Application so it will ignore all of these fields during the diff stage.

Thanks for contributing an answer to Stack Overflow! you have an application that sets managedNamespaceMetadata, But you also have a k8s manifest with a matching name, The resulting namespace will have its annotations set to, Argo CD - Declarative GitOps CD for Kubernetes, # The labels to set on the application namespace, # The annotations to set on the application namespace, # adding this is informational with SSA; this would be sticking around in any case until we set a new value, How ApplicationSet controller interacts with Argo CD, Skip Dry Run for new custom resources types, Resources Prune Deletion Propagation Policy, Replace Resource Instead Of Applying Changes, Fail the sync if a shared resource is found, Generating Applications with ApplicationSet. ArgoCD also has a solution for this and this gets explained in their documentation. 2) In some cases the CRD is not part of the sync, but it could be created in another way, e.g. If the namespace doesn't already exist, or if it already exists and doesn't text applied state.
