Pulumi & Java

    Pulumi supports writing your infrastructure as code using the Java language running on any supported version of Java 11 or later.

    We support running Maven Pulumi programs, Gradle Pulumi programs, and Pulumi programs packaged as JAR files.

    Java is currently in preview. Feedback is greatly appreciated!

    Please post any Bug Reports or Feature Requests in GitHub Issues.


    Install Java 11 or later and Apache Maven 3.6.1 or later.

    Pulumi will need the java, javac, and mvn executables in order to build and run your Pulumi Java application. Ensure that these executables can be found on your path after installation.


    This section describes starting a basic project that you can start to explore with.

    From an empty directory, create a new project:

    $ mkdir myproject && cd myproject
    $ pulumi new java

    To write a Pulumi Java program using Gradle

    $ mkdir myproject && cd myproject
    $ pulumi new java-gradle

    For details around using JAR, please check our docs on Pulumi.yaml

    This will create a maven project with a pom.xml and a Pulumi.yaml project file containing some minimal metadata about your project (including a name and description which you may wish to change) and an App.java file in the src/main/java/myproject directory containing your program.

    To deploy your infrastructure, run pulumi up and Pulumi will build your app using maven (gradle is also supported) and perform the operations needed to deploy the infrastructure you have declared.

    To destroy your infrastructure, run pulumi destroy and Pulumi will terminate the resources that you’ve declared.

    This java template is cloud agnostic, and you will need to install additional Java modules for the cloud provider of your choice. Additional templates are available that do this for you:

    • pulumi new aws-java: creates a starter AWS Java project
    • pulumi new azure-java: creates a starter Azure Java project
    • pulumi new gcp-java: creates a starter Google Cloud Java project


    In your main method, you will want to call Pulumi.run and pass it a method to run that will construct the resources that you’d like to deploy.

    package main;
    import com.pulumi.Pulumi;
    public class Main {
        public static void main(String[] args) {
        public static void stack(Context ctx) {
            // construct your resources here

    You can also use lambda expressions like such:

    public static void main(String[] args) {
        Pulumi.run(ctx -> {
            // construct your resources here

    Datasource Methods

    In order to get information from cloud providers, there are classes that allow you to query cloud services for data. They are named using the convention com.pulumi.providername.servicename.[Servicename]Functions and return a java.util.concurrent.CompletableFuture<T>.

    Pulumi Java implementation details

    Java is currently in preview. These implementation details around how Pulumi integrates with the Java ecosystem are subject to change based on community feedback which is greatly appreciated!

    Please post any Bug Reports or Feature Requests in GitHub Issues.

    The Java Pulumi SDK is available to Go/Java developers in source form on GitHub.

    Plugin Acquisition

    Pulumi will try to auto-detect which plugins your program is using by analyzing your Java project dependencies and then auto-install them. For example, if a program references com.pulumi.aws it will automatically issue the equivalent of $ pulumi plugin install resource aws.

    Running Pulumi with Maven and Gradle

    To support running a Pulumi program with Maven, we use the exec:java target. This requires adding the mainClass property to pom.xml


    To support running a Pulumi program with Gradle, we use the run target. To support plugin resolution and running a Pulumi program in Gradle we check if the mainClass property is set. If it’s set, we’re in plugin resolution. Otherwise, we interpret it as we’re running a Pulumi program.

    application {
        mainClass = project.hasProperty("mainClass")
                ? project.getProperty("mainClass")
                : 'myproject.App'

    Pulumi Programming Model

    The Pulumi programming model defines the core concepts you will use when creating infrastructure as code programs using Pulumi. Concepts describes these concepts with examples available in Java. These concepts are made available to you in the Pulumi SDK.

    The Pulumi programming model includes a core concept of Output values, which are used to track how outputs of one resource flow in as inputs to another resource to resolve dependencies. This concept is important to understand when getting started with Pulumi, and the Inputs and Outputs documentation is recommended to get a feel for how to work with this core part of Pulumi in common cases.

    Unlike other Pulumi languages, Pulumi Java does not have a dedicated Input<T> = T | Output<T> type. Instead, when constructing resource arguments, builders have overloads that accept both a T and an Output<T> value.

    Java Packages

    The Pulumi Registry houses 100+ Java packages.
