Deploy to Azure

You've developed two Azure functions locally. Let's now get your local functions running in the cloud so that you can call them from Slack.


Make sure you activate the sandbox before you continue.

Create an Azure Function App on Azure

You're going to start by creating the Azure Function App using VS Code, and the Azure Functions extension.

  1. Click on View then Command Palette and select Azure Function: Deploy to Function App.

    Deploy To Function App dialog at the top of VS Code.

  2. Confirm that you want to upload the current project.

    Select the folder that you want to deploy. You can also browse to another folder if it's not open anymore by selecting browse underneath the demo-app folder.

  3. Choose the Concierge Subscription sandbox subscription.

  4. Choose +Create New Function App.

    Create New Function App dialog.

  5. Name your app. Select a globally unique name. We'll use mojifier-slack-function-app.

    Choose App Name dialog with the name described previously being typed in.

  6. Select your resource group. The Azure sandbox has created a resource group into which can place your resources. The resource group name is [sandbox resource group name].

  7. Choose the storage account associated with the sandbox.

  8. Once the upload completes, the output window should show a URL.

    Deployment to "mojifier-slack-function-app" completed.

Try it out

You should expect the RespondToSlackCommand function to work since it doesn't rely on any other dependencies.



You should see some json returned.

  "response_type": "in_channel",
  "text": "You must provide an image to mojify",
  "attachments": [
      "image_url": ""

Upload settings

Remember, you have some settings we put in local.settings.json. These settings were the keys and URL for Cognitive Services. Since local.settings.json is local, it's never copied to production when you deploy.

Usually, you would need to open the Azure portal and manually add the settings in the UI, or use func in the Azure CLI. Since you're using VS Code, you can use the Azure Function extension and the command palette to upload your local settings!

  1. Click on View then Command Palette and select Azure Functions: Upload Local Settings.

    Upload Local Setting dialog in VS Code. It says ">upload local".

  2. Choose local.settings.json.

    Choose local.settings.json from the file list.

  3. Choose the subscription that's associated with your function.

  4. Select the function app that you want to upload settings to. In the example, it's called mojifier-slack-function-app.

If everything is working as expected, the MojifyImage endpoint should be working. Visit:


and you should see the mojified image in the window.
