az iot hub module-twin replace

Replace a module twin definition with target json.

Input json directly or use a file path.

az iot hub module-twin replace --device-id
                               --json
                               --module-id

                               [--hub-name]
                               [--login]
                               [--resource-group]

Examples

Replace a module twin with file contents.

az iot hub module-twin replace -d {device_id} -n {iothub_name} -m {module_name} -j ../mymodtwin.json

Required Parameters

--device-id -d

Target Device Id.

--json -j

Json to replace existing twin with. Provide file path or raw json.

--module-id -m

Target Module Id.

Optional Parameters

--auth-type

Indicates whether the operation should auto-derive a policy key or use the current Azure AD session. If the authentication type is login and the resource hostname is provided, resource lookup will be skipped unless needed.You can configure the default using az configure --defaults iothub-data-auth-type={auth-type-value}.

Accepted values: key, login
Default value: key
--etag -e

Etag or entity tag corresponding to the last state of the resource. If no etag is provided the value '*' is used.

--hub-name -n

IoT Hub name or hostname. Required if --login is not provided.

--login -l

This command supports an entity connection string with rights to perform action. Use to avoid session login via "az login". If both an entity connection string and name are provided the connection string takes priority. Required if --hub-name is not provided.

--resource-group -g

Name of resource group. You can configure the default group using az configure --defaults group=<name>.

Global Parameters
