#Validation

Validate Core and the required Aligned Extensions after the installer completes and before you continue with post-install tasks.

#Prerequisites

• The installation completed.
• You can access the platform Web UI address shown by the installer.
• You can run kubectl from the installation node.

#Validate Web UI Access

After the installation is complete, the installer displays the platform access URL. Click Access to open the platform Web UI and verify that the platform login page is reachable.

#Validate Core Applications, Extensions, and Pods

Run the following commands on a control plane node of the new global cluster to confirm the installed state:

# All nodes are Ready
kubectl get nodes

# ClusterModule/global reports the base module as healthy
kubectl get clustermodule global -o jsonpath='{.status.phase}'

# No AppRelease is in a failed state
kubectl get apprelease -A

# Core and Aligned modules report their current phase and version
kubectl get moduleinfo -l cpaas.io/cluster-name=global

# No Pod is stuck outside Running or Completed
kubectl get pod --all-namespaces | awk '{if ($4 != "Running" && $4 != "Completed")print}' | awk -F'[/ ]+' '{if ($3 != $4)print}'

The installation is healthy when:

• All global cluster nodes are Ready.
• ClusterModule/global reports a healthy phase.
• Every AppRelease is in a non-failed state.
• The following applications are installed, and their corresponding ModuleInfo resources report Running at the target version:
  • Alauda Container Platform Web Console
  • Alauda Container Platform Web Console Central
  • Alauda Container Platform Marketplace Web Console
  • Alauda Container Platform Helm Application Catalog
  • Alauda Container Platform Observability Essentials
  • Alauda Container Platform Essentials
  • Alauda Container Platform Cluster Essentials
  • Alauda Container Platform GatewayAPI Plugin
• Critical Pods in cpaas-system are Running or Completed.

In the Web Console, open Administrator > Marketplace > Cluster Plugins and confirm that the required applications are available without an installation failure.
