Deploy a Payara Micro Web App to Azure App Service with Maven

In this quickstart, you'll use the Maven Plugin for Azure App Service Web Apps to deploy a Payara Micro application to Azure App Service on Linux. You'll want to choose Java SE deployment over Tomcat and WAR files when you want to consolidate your app's dependencies, runtime, and configuration into a single deployable artifact.

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


Sign in to Azure CLI

The simplest and easiest way to get the Maven Plugin deploying your PayaraMicro application is by using Azure CLI.

Sign into your Azure account by using the Azure CLI:

az login

Follow the instructions to complete the sign-in process.

Create sample app from MicroProfile Starter

In this section, you'll create a PayaraMicro application and test it locally.

  1. Open a web browser and navigate to the MicroProfile Starter site.

  2. Input or Select the field like follows.

    Field Value
    artifactId payaramicro-hello-azure
    MicroProfile Version MP 3.2
    Java SE Version Java 11
    MicroProfile Runtime PayaraMicro
    Examples for Specifications Metrics, OpenAPI
  3. Select DOWNLOAD to download the project.

  4. Unzip the archive file; for example:


Run the application in Local environment

  1. Change directory to the completed project; for example:

    cd payaramicro-hello-azure/
  2. Build the project using Maven; for example:

    mvn clean package
  3. Run the project; for example:

    java -jar target/payaramicro-hello-azure-microbundle.jar
  4. Test the web app by browsing to it locally using a web browser. For example, you could use the following command if you have curl available:

    curl http://localhost:8080/data/hello
  5. You should see the following message displayed: Hello World

Configure Maven Plugin for Azure App Service

In this section, you'll configure the PayaraMicro project pom.xml file so that Maven can deploy the app to Azure App Service on Linux.

  1. Open the pom.xml file in a code editor.

  2. In the <build> section of the pom.xml file, insert the following <plugin> entry inside the <plugins> tag.

  3. Then you can configure the deployment by running the following Maven command:

    mvn azure-webapp:config

    Select the following options when prompted:

    Input Field Input/Select Value
    Define value for OS(Default: Linux): 1. linux
    Define value for javaVersion(Default: Java 8): 1. Java 11
    Define value for runtimeStack(Default: TOMCAT 8.5): TOMCAT 8.5
    Confirm (Y/N) y

    [!NOTE] Even though we don't use Tomcat, select TOMCAT 8.5 at this time. During the detailed configuration, you'll modify the value from TOMCAT 8.5 to Java11.

    This command produces output similar to the following example:

  4. Modify the runtime entry from TOMCAT 8.5 to java11 and the deployment entry from *.war to *.jar. Then add the <appSettings> section to the <configuration> section of PORT, WEBSITES_PORT, and WEBSITES_CONTAINER_START_TIME_LIMIT. Your XML entry for azure-webapp-maven-plugin should look similar to the following example:


Deploy the app to Azure

After you've configured all of the settings in the preceding sections of this article, you're ready to deploy your web app to Azure. To do so, use the following steps:

  1. From the command prompt or terminal window that you were using earlier, rebuild the JAR file using Maven if you made any changes to the pom.xml file; for example:

    mvn clean package
  2. Deploy your web app to Azure by using Maven; for example:

    mvn azure-webapp:deploy

If you succeeded the deployment, you'll see the following output.

[INFO] Successfully deployed the artifact to

Maven will deploy your web app to Azure. If the web app or web app plan doesn't already exist, it will be created for you. It might take a few minutes before the web app is visible at the URL shown in the output. Navigate to the URL in a Web browser. You should see the following screen.

When your web has been deployed, you can manage it through the Azure portal.

Your web app will be listed in the microprofile resource group, as shown in the following screenshot:

Screenshot of Azure portal showing resource group contents.

You can access to your web app by selecting Browse on the Overview page for your web app. Verify that the deployment was successful and Running. You should see the following screen displayed:

Confirm the log stream from the running App Service

You can see (or "tail") the logs from the running App Service. Any calls to console.log in the site code are displayed in the terminal.

az webapp log tail \
    --resource-group microprofile \
    --name payaramicro-hello-azure-1601009217863

Screenshot of terminal window showing log stream.

Clean up resources

When the Azure resources are no longer needed, clean up the resources you deployed by deleting the resource group.

  • From the Azure portal, select Resource group from the left menu.
  • Enter microprofile in the Filter by name field, the resource group created in this tutorial should have this prefix.
  • Select the resource group created in this tutorial.
  • Select Delete resource group from the top menu.

Next steps

To learn more about MicroProfile and Azure, continue to the MicroProfile on Azure documentation center.
