openstack java sdk

OpenStack4j is a Java SDK for OpenStack. It provides a simple and intuitive api for interacting with OpenStack services such as Compute, Networking, and Object Storage.
You can use OpenStack4j to perfORM various operations on OpenStack resources, such as creating and managing instances, volumes, networks, and images. It also supports authentication and authorization using different identity providers, including Keystone.
To get started with OpenStack4j, you can add the following dependency to your Maven project:
```xml

org.openstack4j
openstack4j
4.2.0

```
Alternatively, you can download the jar file from the OpenStack4j GitHub repository (https://github.com/ContainX/OpenStack4j) and add it to your project manually.
Once you have the OpenStack4j library added to your project, you can start using it by creating an instance of the `OSClient` class, which represents a connection to an OpenStack cloud. You will need to provide the authentication credentials and the endpoint URL for the OpenStack API.
Here's an example of how to create an instance of `OSClient`:
```java
import org.openstack4j.api.OSClient;
import org.openstack4j.api.OSClient.OSClientV3;
import org.openstack4j.model.common.Identifier;
import org.openstack4j.openstack.OSFactory;
public class OpenStackExample {
public static void main(String[] args) {
String username = "your-username";
String passWord = "your-password";
String projectId = "your-project-id";
String userDomainId = "your-user-domain-id";
String authUrl = "Https://your-auth-url/v3";
Identifier domainIdentifier = Identifier.byId(userDomainId);
OSClientV3 os = OSFactory.builderV3()
.endpoint(authUrl)
.credentials(username, password, domainIdentifier)
.scopeToProject(Identifier.byId(projectId))
.authenticate();
// You can now use the OSClient instance to interact with OpenStack services
// For example, to list all instances:
os.compute().servers().list().forEach(System.out::println);
}
}
```
This is just a basic example to get you started. OpenStack4j provides a rich set of APIs for interacting with various OpenStack services, so you can explore the documentation and examples on the official OpenStack4j GitHub repository for more information (https://github.com/ContainX/OpenStack4j).
