Adding Cache Server(s) in AKS at Runtime

To add cache servers at runtime in your Azure Kubernetes cluster, you need to add nodes in NCache deployment and then manually add servers using NCache management tools.

Adding cache server(s) to deployment

You can add cache servers at runtime through the following ways.

• Manual Deployment
• Operator Deployment

1. Execute the following command on the Azure Cloud Shell to increase the number of cache replicas in your deployment.

   kubectl scale --replicas=number_of_total_pods deployment/ncache
   

2. Replica count can also be increased manually by modifying ncache.yaml file.

   • Access ncache.yaml file in a notepad and modify the replicas number under the spec tag according to your requirement.

   • After the YAML file has been modified, run the following command in Azure Cloud Shell to apply the changes made to the deployment.

     kubectl apply -f [dir]/ncache.yaml 
     

Adding cache server(s) to the NCache cluster

Cache servers can be added to an NCache cluster through the following ways:

1. Follow these steps to add cache servers through NCache Management Center.

   • Access NCache Management Center from [gatewayIPAddress]:9801
   • Follow the steps provided in Add Server Nodes once you have accessed the manager.

2. To add cache servers through PowerShell, follow the steps mentioned in Adding Cache Servers through PowerShell.

After the required cache servers have been added to the cache cluster, you can view these changes from the NCache Management Center. You can also monitor the cluster and check its stats. See Monitor NCache Cluster and Clients
