Running the application locally with Docker

If your system has a different version of Node.js, you can run the application locally in a Docker container.

To run the application locally with Docker, complete the following steps:

1. Export the IoT Hub connection string and the Avatar storage environment variables (located in the configuration of the function app) to the following environment variables:

   • IOT_HUB_CONNECTION_STRING

   • AVATAR_STORAGE_ACCOUNT_NAME

   • AVATAR_STORAGE_ACCESS_KEY

   • FOTA_STORAGE_ACCOUNT_NAME

   • FOTA_STORAGE_ACCESS_KEY

   • HISTORICAL_DATA_COSMOSDB_CONNECTION_STRING

2. Make sure to include the following settings in your local.settings.json file:

   {
       "IsEncrypted": false,
       "Values": {
           "IoTHubEventHubCompatibleConnectionString": "...",
           "AzureWebJobsStorage": "...",
           "IoTHubEventHubName": "...",
           "SignalRConnectionString": "..."
       },
       "Host": {
           "CORS": "*",
           "CORSCredentials": false
       }
   }
   

3. Run the following command to list the environment variables of the function app and export them:

   az functionapp config appsettings list \
       --resource-group ${RESOURCE_GROUP_NAME:-bifravst} \
       --name ${APP_NAME:-bifravst}API | jq -r '.[] | .name + "=\"" + .value + "\""'
   

4. Run the function app by using the following command:

   docker run --rm --net=host -P \
       -e IOT_HUB_CONNECTION_STRING \
       -e AVATAR_STORAGE_ACCOUNT_NAME \
       -e AVATAR_STORAGE_ACCESS_KEY \
       -e FOTA_STORAGE_ACCOUNT_NAME \
       -e FOTA_STORAGE_ACCESS_KEY \
       -e HISTORICAL_DATA_COSMOSDB_CONNECTION_STRING \
       -e UNWIREDLABS_API_KEY \
       -e UNWIREDLABS_API_ENDPOINT \
       -v ${PWD}:/workdir bifravst/azure-dev:latest \
       func start --typescript
   

You can now use http://localhost:7071/ as your REACT_APP_AZURE_API_ENDPOINT for the app.
