#The sku-name parameter value follows the convention {pricing tier}_{compute generation}_{vCores} as in the examples below:
# --sku-name B_Gen5_2 maps to Basic, Gen 5, and 2 vCores.
# --sku-name GP_Gen5_32 maps to General Purpose, Gen 5, and 32 vCores.
# --sku-name MO_Gen5_2 maps to Memory Optimized, Gen 5, and 2 vCores.
#WARNING - this might error out if your region doesn't support the SKU you set here. If it does, execute:
#az group delete -g [resource group] to drop everything and try again

#The SKU below is good for a Ghost blog, but if you're going to host something more, consider more RAM/Cores
#The nice thing about Ghost is Node - it's quite performant on lesser hardware
SKU=B_Gen5_1 #this is the cheapest one
