Alauda Container Platform

Creating applications by using Operator Backed

Operator backed applications are collections of resources provided by the Operator. Based on these Operator backed applications, you can quickly deploy a component application and leverage the capabilities of the Operator to automate the entire lifecycle management of the application.

Procedure

  1. Container Platform, navigate to Applications > Applications in the left sidebar.

  2. Click Create.

  3. Choose Create from Catalog as the creation approach.

  4. Select an Operator-Backed Instance and Configure Custom Resource Parameters. Select an Operator-managed application instance and configure its Custom Resource (CR) specifications in the CR manifest, including:

    • spec.resources.limits (container-level resource constraints).
    • spec.resourceQuota (Operator-defined quota policies). Other CR-specific parameters such as spec.replicas, spec.storage.className, etc.

  5. Click Create.

The web console will navigate to Applications > Operator Backed Apps page.

INFO

Note: The Kubernetes resource creation process requires asynchronous reconciliation. Completion may take several minutes depending on cluster conditions.

Troubleshooting

If resource creation fails:

  1. Inspect controller reconciliation errors: 
    kubectl get events --field-selector involvedObject.kind=<Your-Custom-Resource> --sort-by=.metadata.creationTimestamp
  2. Verify API resource availability: 
    kubectl api-resources | grep <Your-Resource-Type>
  3. Retry creation after verifying CRD/Operator readiness: 
    kubectl apply -f your-resource-manifest.yaml
