If the namespace doesn't already exist, or if it already exists and doesn't If we click on it we see this detail difference view: This means, the object is not known by ArgoCD at all! Argo CD is a combination of the two terms "Argo" and "CD," Argo being an open source container-native workflow engine for Kubernetes. When a policy changes in the git repository, ArgoCD detects the change and reconciles the desired state with actual state making the cluster converge to the state described in git. More information about those policies could be found here. The example below shows how to configure Argo CD to ignore changes made by kube-controller-manager in Deployment resources. The application below deploys the kyverno-policies helm chart without specifying ignoreDifferences and therefore will suffer the continuous OutOfSync symptoms: To fix the issue, we need to fill in the ignoreDifferences stanza in the Application spec with the correct path expression to match only generated rules. after the other resources have been deployed and become healthy, and after all other waves completed successfully. Uses 'diff' to render the difference. in a given Deployment, the following yaml can be provided to Argo CD: Note that by the Deployment schema specification, this isn't a valid manifest.

Solving configuration drift using GitOps with Argo CD You will be . Fortunately we can do just that using the. 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 ;-).

Well occasionally send you account related emails. Please try using group field instead. These extra fields would get dropped when querying Kubernetes for the live state, Some CRDs are re-using data structures defined in the Kubernetes source base and therefore inheriting custom You can do using this annotations: If you want to exclude a whole class of objects globally, consider setting resource.customizations in system level configuration.
