Java SDK Reference - Daytona

The Daytona Java SDK provides a robust interface for programmatically interacting with Daytona Sandboxes. It targets Java 11+ and uses OkHttp and Jackson.

Installation

Gradle

Add the Daytona SDK dependency to your build.gradle.kts:

kotlin

dependencies {
    implementation("io.daytona:sdk-java:0.1.0")
}

Maven

Add the Daytona SDK dependency to your pom.xml:

xml

<dependency>
  <groupId>io.daytona</groupId>
  <artifactId>sdk-java</artifactId>
  <version>0.1.0</version>
</dependency>

Getting Started

Create a Sandbox

Create a Daytona Sandbox to run your code securely in an isolated environment. The following snippet is an example "Hello World" program that runs securely inside a Daytona Sandbox.

java

import io.daytona.sdk.Daytona;
import io.daytona.sdk.Sandbox;
import io.daytona.sdk.model.ExecuteResponse;

public class Main {
    public static void main(String[] args) {
        // Initialize the SDK (uses environment variables by default)
        try (Daytona daytona = new Daytona()) {
            // Create a new sandbox
            Sandbox sandbox = daytona.create();

            // Execute a command
            ExecuteResponse response = sandbox.getProcess().executeCommand("echo 'Hello, World!'");
            System.out.println(response.getResult());

            // Clean up
            sandbox.delete();
        }
    }
}

Configuration

The Daytona SDK can be configured using environment variables or by passing a configuration object:

java

// Using environment variables (DAYTONA_API_KEY, DAYTONA_API_URL, DAYTONA_TARGET)
Daytona daytona = new Daytona();

java

// Using explicit configuration
DaytonaConfig config = new DaytonaConfig.Builder()
    .apiKey("YOUR_API_KEY")
    .apiUrl("YOUR_API_URL")
    .target("us")
    .build();
Daytona daytona = new Daytona(config);
