Module owners MUST create the defaults, waf-aligned folders within their /tests/e2e/ directory in their resource module source code and SHOULD create a max folder also. Module owners CAN create additional folders as required. Each folder will be used as described for various test cases.

A Pattern Module MAY create Resource Group(s).

A Pattern Module SHOULD be built from AVM Resources Modules to establish a standardized code base and improve maintainability. If a valid reason exists, a pattern module MAY contain native resources (“vanilla” code) where it’s necessary. A Pattern Module MUST NOT contain references to non-AVM modules.

A Pattern Module MAY contain and be built using other AVM Pattern Modules. A Pattern Module MUST NOT contain references to non-AVM modules.

An item MUST be logged onto as an issue on the AVM Central Repo (Azure/Azure-Verified-Modules) if a Resource Module does not exist for resources deployed by the pattern module.

If the Resource Module adds no value, see Resource Module functional requirement ID: RMFR2 .

Parameter/variable input names SHOULD contain the resource to which they pertain. E.g., virtualMachineSku/virtualmachine_sku

A resource module MUST only deploy a single instance of the primary resource, e.g., one virtual machine per instance.

Multiple instances of the module MUST be used to scale out.

A resource module MUST NOT create a Resource Group for resources that require them.

In the case that a Resource Group is required, a module MUST have an input (scope or variable):

• In Bicep the targetScope MUST be set to resourceGroup or not specified (which means default to resourceGroup scope)
• In Terraform the variable MUST be called resource_group_name

Scopes will be covered further in the respective language specific specifications.

Resource modules support the following optional features/extension resources, as specified, if supported by the primary resource. The top-level variable/parameter names MUST be:

Resource modules MUST implement a common interface, e.g. the input’s data structures and properties within them (objects/arrays/dictionaries/maps), for the optional features/extension resources:
