Using OpenStack4j to Create a Private Image

IMS supports the native OpenStack Glance v2 image API, with which you can create a private image with your image file. The supported image types are VHD, ZVHD, QCOW2, and VMDK.

The following uses the image in the QCOW2 format as an example. Image uploading takes a long time, which depends on the image size and network quality.

//Create an Image. 
Image createdImage = os.imagesV2().create(Builders.imageV2() 
//Upload the image's image file. 
Payload<File> payload = Payloads.create(new File("root.img")); 
ActionResponse uploadResult = os.imagesV2().upload(createdImage.getId(), payload, os.imagesV2().get(createdImage.getId())); 
System.out.println("Uploaded done");
