 ## Sandbox
 
 In the context of `az bake`, a _sandbox_ is a collection of resources in a resource group that are used to create (or _"bake"_) custom VM images. It's a secure, self-contained environment where [Packer][packer-docs] will be executed from [Azure Container Instance][azure-aci] in a private virtual network. A sandbox is required to use `az bake`. You can be create a new sandbox using the [`az bake sandbox create`](bake/azext_bake/_arm.py#az-bake-sandbox-create) command.
