Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. It automates the deployment of the desired application states in Kubernetes clusters, ensuring that the live state matches the desired state defined in Git repositories. Argo CD is widely used for its ability to manage complex deployments and rollbacks efficiently.
One common issue users encounter is the 'Resource not found' error. This error typically manifests when Argo CD cannot locate a specified resource within the Kubernetes cluster. Users may notice this error in the Argo CD UI or logs, indicating a discrepancy between the desired state and the live state of the application.
This error occurs when a resource defined in the application manifest does not exist in the cluster. It could be due to a missing resource, a typo in the resource name, or an incorrect namespace specification. This discrepancy prevents Argo CD from synchronizing the application state.
Some common scenarios leading to this error include:
First, ensure that all resources defined in your application manifest are created in the cluster. Use the following command to list resources:
kubectl get all -n <namespace>
Replace <namespace> with the appropriate namespace. Verify that all expected resources are listed.
Ensure that the resources are in the correct namespace. If your manifest specifies a namespace, verify that the resources are deployed there. You can switch namespaces using:
kubectl config set-context --current --namespace=<namespace>
Review your application manifest for any typographical errors in resource names or kinds. Correct any discrepancies and redeploy the manifest.
