        .flavor("large")
        .image("imageId")
        .build();

// Boot the Server
Server server = os.compute().servers().boot(server);
```

### OpenStack Image Creation

Source: https://openstack4j.github.io

Creates a new image with specified properties like name, visibility, container format, and disk format, and uploads it from a file.

```java
// Create an Image
Image image = os.images().create(Builders.image()
        .name("Cirros 0.3.0 x64")
        .isPublic(true)
        .containerFormat(ContainerFormat.BARE)
        .diskFormat(DiskFormat.QCOW2)
        .build()
        ), Payloads.create(new File("cirros.img")));

Source: https://openstack4j.github.io

Authenticates with OpenStack using Identity V3 endpoint, credentials, and project scope.

```java
// V3 authentication
OSClientV3 os = OSFactory.builderV3()
        .endpoint("http://127.0.0.1:5000/v3")
        .credentials("admin", "secret", Identifier.byName("Default"))
