» 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.
ip_filter_rule - (Optional) One or more ip_filter_rule blocks as defined below.
route - (Optional) A route block as defined below.
fallback_route - (Optional) A fallback_route block as defined below. If the fallback route is enabled, messages that don't match any of the supplied routes are automatically sent to this route. Defaults to messages/events.
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.

NOTE: Only one IotHub can be on the Free tier per subscription.

capacity - (Required) The number of provisioned IoT Hub units.

An endpoint block supports the following:

type - (Required) The type of the endpoint. Possible values are AzureIotHub.StorageContainer, AzureIotHub.ServiceBusQueue, AzureIotHub.ServiceBusTopic or AzureIotHub.EventHub.
connection_string - (Required) The connection string for the endpoint.
name - (Required) The name of the endpoint. The name must be unique across endpoint types. The following names are reserved: events, operationsMonitoringEvents, fileNotifications and $default.
batch_frequency_in_seconds - (Optional) Time interval at which blobs are written to storage. Value should be between 60 and 720 seconds. Default value is 300 seconds. This attribute is mandatory for endpoint type AzureIotHub.StorageContainer.
max_chunk_size_in_bytes - (Optional) Maximum number of bytes for each blob written to storage. Value should be between 10485760(10MB) and 524288000(500MB). Default value is 314572800(300MB). This attribute is mandatory for endpoint type AzureIotHub.StorageContainer.
container_name - (Optional) The name of storage container in the storage account. This attribute is mandatory for endpoint type AzureIotHub.StorageContainer.
encoding - (Optional) Encoding that is used to serialize messages to blobs. Supported values are 'avro' and 'avrodeflate'. Default value is 'avro'. This attribute is mandatory for endpoint type AzureIotHub.StorageContainer.
file_name_format - (Optional) File name format for the blob. Default format is {iothub}/{partition}/{YYYY}/{MM}/{DD}/{HH}/{mm}. All parameters are mandatory but can be reordered. This attribute is mandatory for endpoint type AzureIotHub.StorageContainer.

An ip_filter_rule block supports the following:

name - (Required) The name of the filter.
ip_mask - (Required) The IP address range in CIDR notation for the rule.
action - (Required) The desired action for requests captured by this rule. Possible values are Accept, Reject

A route block supports the following:

name - (Required) The name of the route.
source - (Required) The source that the routing rule is to be applied to, such as DeviceMessages. Possible values include: RoutingSourceInvalid, RoutingSourceDeviceMessages, RoutingSourceTwinChangeEvents, RoutingSourceDeviceLifecycleEvents, RoutingSourceDeviceJobLifecycleEvents.
condition - (Optional) The condition that is evaluated to apply the routing rule. If no condition is provided, it evaluates to true by default. For grammar, see: https://docs.microsoft.com/azure/iot-hub/iot-hub-devguide-query-language.
endpoint_names - (Required) The list of endpoints to which messages that satisfy the condition are routed.
enabled - (Required) Used to specify whether a route is enabled.

A fallback_route block supports the following:

source - (Optional) The source that the routing rule is to be applied to, such as DeviceMessages. Possible values include: RoutingSourceInvalid, RoutingSourceDeviceMessages, RoutingSourceTwinChangeEvents, RoutingSourceDeviceLifecycleEvents, RoutingSourceDeviceJobLifecycleEvents.
condition - (Optional) The condition that is evaluated to apply the routing rule. If no condition is provided, it evaluates to true by default. For grammar, see: https://docs.microsoft.com/azure/iot-hub/iot-hub-devguide-query-language.
endpoint_names - (Optional) The endpoints to which messages that satisfy the condition are routed. Currently only 1 endpoint is allowed.
enabled - (Optional) Used to specify whether the fallback route is enabled.

» Attributes Reference

The following attributes are exported:

id - The ID of the IoTHub.

event_hub_operations_path - The EventHub compatible path for operational data

NOTE: These fields can be used in conjunction with the shared_access_policy block to build a connection string

hostname - The hostname of the IotHub Resource.
shared_access_policy - One or more shared_access_policy blocks as defined below.

A shared access policy block contains the following:

key_name - The name of the shared access policy.
primary_key - The primary key.
secondary_key - The secondary key.
permissions - The permissions assigned to the shared access policy.

» Import

IoTHubs can be imported using the resource id, e.g.
