Description

This article provides detailed information about how to change the node naming format to allow the Windows node pools in Sitecore Managed Cloud containerized deployment to be scaled out or in without causing the node pool to be recreated.

Limitations and Risks

• Applying this change causes the Windows node pools to be recreated, which results in downtime. This change should be applied during the maintenance period.
• This change only allows the node pool to scale in or out without recreation. Changing the node scale tier still requires recreation.

How to apply

1. Navigate to the infrastructure repository.
2. Edit main.tf in the root folder of the repository.
3. Find the following line:

   primary_windows_nodepool_name = "p${substr(replace(local.config.aks.windows_vm_size, "_", ""), length(local.config.aks.windows_vm_size)-4, -1)}${local.config.aks.windows_node_count}" 

   and replace it with:

   primary_windows_nodepool_name = "p${substr(replace(local.config.aks.windows_vm_size, "_", ""), length(local.config.aks.windows_vm_size)-4, -1)}" 

4. Find the following line:

   scaled_windows_nodepool_name  = "s${try(substr(replace(local.config.aks.windows_scaled_vm_size, "_", ""), length(local.config.aks.windows_scaled_vm_size)-4, -1),"")}${try(local.config.aks.windows_scaled_node_count, 0)}"

   and replace it with:

   scaled_windows_nodepool_name  = "s${try(substr(replace(local.config.aks.windows_scaled_vm_size, "_", ""), length(local.config.aks.windows_scaled_vm_size)-4, -1),"")}"

5. Run the infrastructure pipeline.
