Custom domain option - cristianoag/microsoft-teams-apps-company-communicator GitHub Wiki

As an alternative to using Azure Front Door, you can register a custom domain for your app.

Fresh deployment

Follow the steps in the Deployment guide, modified as follows:

  1. Follow Step 1: Register Azure AD application unchanged.
  2. When filling in the template parameters in Step 2: Deploy to your Azure subscription, set
    • Custom domain option = "Custom domain name (recommended)"
  3. Pause after Step 2.
  4. Assign a custom domain name to the Azure App Service that was created by the template. You have several options:
  5. Bind an SSL certificate to your Azure App Service: https://docs.microsoft.com/en-us/azure/app-service/app-service-web-tutorial-custom-ssl
  6. Test the custom domain before proceeding. Ensure that you can access https://<your_custom_domain>/health without any errors. (This is a blank page that returns HTTP 200 OK.)
  7. Go to the Azure App Service page in the Azure Portal, click on "Configuration", then set
    • AzureAd:ApplicationIdURI = api://<your_domain_name> (for example, api://companycommunicator.contoso.com)
  8. Continue with the rest of the deployment guide, substituting your domain name for %appDomain%.
    • For example, if your custom domain is companycommunicator.contoso.com, you would set the Redirect URI of your Azure AD application to https://companycommunicator.contoso.com/signin-simple-end, and its Application URI would be api://companycommunicator.contoso.com.
