PowerShell and CLI to manage App Service Plan sizing

Manage-App-Service-Plan.md

Manage App Service Plan count and SKU

Get the number of worker nodes serving the app service plan

(Get-AzAppServicePlan -ResourceGroupName "<resource group name>" -Name "<app service plan name>").Sku.Capacity

az appservice plan show --resource-group "<resource group name>" --name "<app service plan name>" --output jsonc --query "sku.capacity"

Update the number of worker nodes

Since you are leveraging PremiumV2, the allowed values are 1-30

Set-AzAppServicePlan -ResourceGroupName "<resource group name>" -Name "<app service plan name>" -NumberOfWorkers <1 - 30>

az appservice plan update --resource-group "<resource group name>" --name "<app service plan name>" --number-of-workers <1 - 30>

Gets the SKU (pricing tier) for the app service plan

(Get-AzAppServicePlan -ResourceGroupName "<resource group name>" -Name "<app service plan name>").Sku.Size

az appservice plan show --resource-group "<resource group name>" --name "<app service plan name>" --output jsonc --query "sku.size"

Updates the SKU (pricing tier) for the app service plan

Set-AzAppServicePlan -ResourceGroupName "<resource group name>" -Name "<app service plan name>" -WorkerSize "<Small | Medium | Large>"

az appservice plan update --resource-group "<resource group name>" --name "<app service plan name>" --sku "<P1v2 | P2v2 | P3v2>"

Getting the available Skus, sizes and worker count for a plan

Unfortunately, there isn't a PowerShell to get the available SKUs. Instead, you can get this via a REST call. The documentation for this can be found here:
