Azure IoT EdgeHub Dev Tool

Project description

Azure IoT EdgeHub Dev Tool Build Status


The Azure IoT EdgeHub Dev Tool is in a maintenance mode. Please see this announcement for more details. We recommend using VM, Physical devices or EFLOW.


The Azure IoT EdgeHub Dev Tool provides a local development experience with a simulator for creating, developing, testing, running, and debugging Azure IoT Edge modules and solutions.

The simulator allows you to run, test and debug your own custom IoT Edge modules locally, without the IoT Edge Runtime, and with the following benefits:

  • Your custom Edge module code is the same whether running on the simulator or the full IoT Edge Runtime.
  • Your Edge solution can be run locally without the need to push new images or create IoT Edge deployment manifests.
  • The only credential required to run your Edge solution on the simulator is the IoT Edge Device Connection String. The IoT Hub Connection String is not needed.
  • It helps you debug your custom Edge modules on the host and not just in the container.

The following table compares the requirements to run your solution on the IoT Edge Runtime and iotedgehubdev tool:

IoT Edge Runtime iotedgehubdev
Device Credential Needed YES YES
IoT Hub Credential Needed YES NO
Build Image YES YES
Push Image YES NO
Create Deployment YES NO
Support native debug scenario NO YES


  1. Install Docker CE (18.02.0+) on Windows, macOS or Linux

  2. Install Docker Compose (1.20.0+) (Linux only. Compose has already been included in Windows/macOS Docker CE installation)

  3. Install Python (3.5/3.6/3.7/3.8/3.9) and Pip

  4. Install iotedgehubdev by running the following command in your terminal:

    pip install --upgrade iotedgehubdev
  5. Ensure the user is a member of docker user group (Linux / MacOS only):

    sudo usermod -aG docker $USER

Please make sure there is no Azure IoT Edge runtime running on the same machine as iotedgehubdev since they require the same ports.


1. Setup

iotedgehubdev setup -c "<edge-device-connection-string>"

2. Start/Stop an IoT Edge solution in simulator

iotedgehubdev start -d <path/to/deployment-manifest>
iotedgehubdev stop

3. Start and debug a single module natively

  1. Start the module with specific input(s) and/or environment variable(s)

    iotedgehubdev start -i "<module-inputs>"
    // OR
    iotedgehubdev start -i "<module-inputs>" -e "<environment-variable>"

    For example:
    iotedgehubdev start -i "input1,input2" -e "TestEnv1=Value1" -e "TestEnv2=Value2"

  2. Output the module credential environment variables

    iotedgehubdev modulecred
  3. Start your module natively with the environment variables from the previous step

  4. Send a message to your module through the RESTful API

    For example:
    curl --header "Content-Type: application/json" --request POST --data '{"inputName": "input1","data": "hello world"}' http://localhost:53000/api/v1/messages

  5. Stop the simulator

    iotedgehubdev stop
