Azure-docs: 'device-identity' is not in the 'az iot hub' command group.

[sethderrick]

When attempting to follow along with this quickstart I am blocked because 'device-identity' is not in the 'az iot hub' command group according to the cli. I've tried the cli on Windows, Mac and the built-in web-based cli you link to. All show the same error.

Seems like a step was missed. The iot extension is needed for this command set to work:

"Run the following command to add the Microsoft Azure IoT Extension for Azure CLI to your Cloud Shell instance. The IOT Extension adds IoT Hub, IoT Edge, and IoT Device Provisioning Service (DPS) specific commands to Azure CLI.

az extension add --name azure-cli-iot-ext
"

reassign JimacoMS3

As this step already does exist in the Prerequisites section, I'm closing this issue.

az iot hub: 'device-identity' is not in the 'az iot hub' command group. See 'az iot hub --help'.i am getting this error

[JimacoMS3]

@nupur0308 Have you added the Azure IoT Extension for Azure CLI (azure-cli-iot-ext) to your environment as specified in the Prerequisites?

If so, you should be able to run the following command and see similar results:

az extension list

[
  {
    "extensionType": "whl",
    "name": "azure-cli-iot-ext",
    "version": "0.7.1"
  }
]

[nupur0308]

its working now.

thanks

@JimacoMS3 I have been experiencing this problem for a while now (and avoiding Azure CLI for that reason). It seems that it's still not fixed. Here's what I see when using the Cloud Shell from portal.azure.com

@JimacoMS3 My bad (leaving the comment above in case someone else trips like I did). I completely lost track of the fact that users must maintain Azure environment (!?). My problem was due to an old extension in my Azure Cloud environment.

Hi @radoye

Glad you were able to get it figured out, and thanks for leaving the comment :)

HI All,

Question about az iot hub device-identity create ....

when I executed code via PHP's exec() syntax

exec("/usr/bin/az iot hub device-identity create -n {IOT HUB NAME} -d {DEVICE ID} 2>&1")

it gives me an output like this

{
    "message": "az iot hub: 'device-identity' is not in the 'az iot hub' command group. See 'az iot hub --help'. If the command is from an extension, please make sure the corresponding extension is installed. To learn more about extensions, please visit https://docs.microsoft.com/en-us/cli/azure/azure-cli-extensions-overview"
}

But when i execute the az iot hub device-identity create through console, it works as expected.

Can anyone inspect code where I do wrong.

Thanks

[JimacoMS3]

Hi @slamgundam,

So I don't really know much - read that as anything :) - about PHP. If the command works in a (local) console window on your computer, but doesn't work from inside the exec command in PHP, then the issue is that whatever environment the exec command is running in can't access the azure-iot extension.

You might try running the command using the shell_exec() PHP command. Alternatively, you can check out the Azure CLI documentation here: https://docs.microsoft.com/cli/azure/azure-cli-extensions-overview?view=azure-cli-latest#install-extension. The last two sentences of that section explain how the Azure CLI finds extensions. One thing to note is that it looks like the extensions live in your user profile and Azure CLI defaults there if the environment variable isn't set -- so that could be why exec() isn't finding them. Again, I don't know much here.

If the above doesn't help, I would suggest that you search stack overflow or post there. I'd suggest using tags like azure-cli and/or php. This thread has an extremely limited audience (me :)), and is really focused on IoT Hub documentation issues. You'll probably get a much more helpful response on stack overflow.

Hope this helps,

Jimaco
