Create a function in the Azure portal that runs on a schedule

Learn how to use the Azure portal to create a function that runs serverless on Azure based on a schedule that you define.

[!INCLUDE functions-in-portal-editing-note]

Prerequisites

To complete this tutorial:

Ensure that you have an Azure subscription. If you don't have an Azure subscription, create a free account before you begin.

Create a function app

[!INCLUDE Create function app Azure portal]

Your new function app is ready to use. Next, you create a function in the new function app.

Create a timer triggered function

  1. In your function app, select Overview, and then select + Create under Functions.

    :::image type="content" source="./media/functions-create-scheduled-function/function-create-function.png" alt-text="Screenshot of adding a function in the Azure portal." border="true":::

  2. Under Select a template, scroll down and choose the Timer trigger template.

    :::image type="content" source="./media/functions-create-scheduled-function/function-select-timer-trigger-template.png" alt-text="Screenshot of select the timer trigger page in the Azure portal." border="true":::

  3. In Template details, configure the new trigger with the settings as specified in the table below the image, and then select Create.

    :::image type="content" source="./media/functions-create-scheduled-function/function-configure-timer-trigger-new.png" alt-text="Screenshot that shows the New Function page with the Timer Trigger template selected." border="true":::

    Setting Suggested value Description
    Name Default Defines the name of your timer triggered function.
    Schedule 0 */1 * * * * A six field CRON expression that schedules your function to run every minute.

Test the function

  1. In your function, select Code + Test and expand the Logs.

    :::image type="content" source="./media/functions-create-scheduled-function/function-code-test-timer-trigger.png" alt-text="Screenshot of the Test the timer trigger page in the Azure portal." border="true":::

  2. Verify execution by viewing the information written to the logs.

    :::image type="content" source="./media/functions-create-scheduled-function/function-timer-logs-view.png" alt-text="Screenshot showing the View the timer trigger page in the Azure portal." border="true":::

Now, you change the function's schedule so that it runs once every hour instead of every minute.

Update the timer schedule

  1. In your function, select Integration. Here, you define the input and output bindings for your function and also set the schedule.

  2. Select Timer (myTimer).

    :::image type="content" source="./media/functions-create-scheduled-function/function-update-timer-schedule-new.png" alt-text="Screenshot of Update the timer schedule page in the Azure portal." border="true":::

  3. Update the Schedule value to 0 0 */1 * * *, and then select Save.

    :::image type="content" source="./media/functions-create-scheduled-function/function-edit-timer-schedule.png" alt-text="Screenshot of the Update function timer schedule page in the Azure portal." border="true":::

You now have a function that runs once every hour, on the hour.
