Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. It automates the deployment of the desired application states in the specified target environments. By continuously monitoring Git repositories, Argo CD ensures that the live state of applications matches the desired state defined in Git.
When using Argo CD, you might encounter an 'Invalid manifest error'. This error typically occurs when there are issues with the application manifest files, which are crucial for defining the desired state of your Kubernetes applications.
Developers may notice that applications fail to sync or deploy correctly. The Argo CD UI or logs may display error messages indicating invalid manifests, preventing successful application deployment.
The 'Invalid manifest error' is usually caused by syntax errors or invalid configurations within the manifest files. These files are YAML or JSON documents that describe the desired state of your Kubernetes resources.
To resolve this issue, you need to validate and correct the manifest files. Here are the steps you can follow:
Use the following command to validate your manifest files:
kubectl apply --dry-run=client -f <path-to-manifest>
This command checks for syntax errors without applying the changes to the cluster.
Once the errors are corrected, reapply the manifests using:
kubectl apply -f <path-to-manifest>
This command will apply the changes to your Kubernetes cluster.
For more information on writing valid Kubernetes manifests, refer to the Kubernetes Documentation. To learn more about Argo CD, visit the official Argo CD documentation.
By following these steps and utilizing the resources provided, you can effectively resolve the 'Invalid manifest error' and ensure smooth application deployments with Argo CD.
