Creating an app service plan

To create an app service plan, which is a prerequisite to creating a web app and sets the compute/pricing, use az appservice plan create:

az appservice plan create \
    --resource-group $rg \
    --name $app_plan \
    --sku B1 \
    --is-linux

$rg is the existing resource group’s name, and $app_plan is the new app service’s name.
