» Argument Reference

The following arguments are supported:

  • name - (Required) Specifies the name of the IotHub resource. Changing this forces a new resource to be created.

  • resource_group_name - (Required) The name of the resource group under which the IotHub resource has to be created. Changing this forces a new resource to be created.

  • location - (Required) Specifies the supported Azure location where the resource has to be createc. Changing this forces a new resource to be created.

  • sku - (Required) A sku block as defined below.

  • endpoint - (Optional) An endpoint block as defined below.

  • route - (Optional) A route block as defined below.

  • tags - (Optional) A mapping of tags to assign to the resource.

A sku block supports the following:

  • name - (Required) The name of the sku. Possible values are B1, B2, B3, F1, S1, S2, and S3.

  • tier - (Required) The billing tier for the IoT Hub. Possible values are Basic, Free or Standard.
