--name vm01 \
--image Ubuntu2404 \
--size Standard_B1s \
--admin-username azureuser \
--generate-ssh-keys \
--storage-sku Standard_LRS \
--nics nic01 \
--os-disk-delete-option delete 

 

az vm list \
--resource-group rg9999999 

 

VMインスタンス削除
az vm delete \
--resource-group rg9999999 \

--size Standard_B1ls

 

# Start the VM
az vm start \
