In general, we can divide out-of-sync differences into two groups: differences in an object: That's the case if you have an object defined in a manifest and now some attributes get changed or added without any changes in your gitops repostory, whole objects as differences: This is the case if someone adds new objects in your namespace where your app is located and managed by ArgoCD, With ArgoCD you can solve both cases just by changing a few manifests ;-). kubectl.kubernetes.io/last-applied-configuration annotation that is added by kubectl apply. The example below shows a configuration to ignore a Deployments replicas field from the desired state during the diff and sync stages: This is particularly useful for resources that are incompatible with GitOps because a field value is required during resource creation and is also mutated by controllers after being applied to the cluster. Uses 'diff' to render the difference. It is possible for an application to be OutOfSync even immediately after a successful Sync operation. Is there a way to tell ArgoCD to just completely disregard any child resources created by a resource managed by Argo? case an additional sync option must be provided to skip schema validation. after the other resources have been deployed and become healthy, and after all other waves completed successfully. The ignoreResourceStatusField setting simplifies Argo CD cannot find the CRD in the sync and will fail with the error the server could not find the requested resource. Argo CD shows two items from linkerd (installed by Helm) are being out of sync. 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! We will use a JQ path expression to select the generated rules we want to ignore: Now, all generated rules will be ignored by ArgoCD, and Kyverno policies will be correctly kept in sync in the target cluster . Would you ever say "eat pig" instead of "eat pork"? Argo CD reports and visualizes the differences, while providing facilities to automatically or manually sync the live state back to the desired target state. Examining the managedFields above, we can see that the rollouts-controller manager owns some fields in the Rollout resource. privacy statement. Compare Options - Argo CD - Declarative GitOps CD for Kubernetes Compare Options Ignoring Resources That Are Extraneous v1.1 You may wish to exclude resources from the app's overall sync status under certain circumstances. What is an Argo CD? The diffing customization can be configured for single or multiple application resources or at a system level. If you want to ignore certain differences which may occur in a specific object then you can set an annotation in this object as described in the argocd-documentation: It gets more interesting if you want to ignore certain attributes in all objects or in all objects of a certain kind of your app. Version.

Thanks for contributing an answer to Stack Overflow! ArgoCD doesn't sync correctly to OCI Helm chart? configuring ignore differences at the system level. The ArgoCD resource is a Kubernetes Custom Resource (CRD) that describes the desired state for a given Argo CD cluster and allows for the configuration of the components that make up an Argo CD cluster. Asking for help, clarification, or responding to other answers. I tried the following ways to ignore this code snippet: kind: StatefulSet In some other cases, this approach isnt an option as users are deploying Helm charts that dont provide the proper configuration to remove the replicas field from the generated manifests. Getting Started with ApplicationSets. It can be enabled at the application level like in the example below: To enable ServerSideApply just for an individual resource, the sync-option annotation And none seems to work, and I was wondering if this is a bug into Argo. In this KUBECTL_EXTERNAL_DIFF environment variable can be used to select your own diff tool. argocd-application-controller kube-controller-manager In such cases you Argo CD has the ability to automatically sync an application when it detects differences between the desired manifests in Git, and the live state in the cluster. We can configure the ArgoCD Application so it will ignore all of these fields during the diff stage. --- apiVersion: argoproj.io/v1alpha1 kind: Application metadata: name: elastic-operator labels: argocd.application.type: "system" spec: ignoreDifferences: - group: admissionregistration.k8s.io kind: ValidatingWebhookConfiguration jsonPointers: - /webhooks//clientConfig/caBundle - group: admissionregistration.k8s.io kind: Looking for job perks?
