An image is a complete copy of the file system structure and data on a disk.
It is designed to quickly create a data disk, primarily, a VM boot disk. Images can be used for distributing software, such as OS distributions or disks with pre-installed software.
You can use images with outdated OS versions on your VMs; however, you will not be able to get support for these VMs if you have any issues.
To regularly back up your data on disks, use snapshots.
You can create an image from a disk, snapshot, or another image. If you have an image file, you can import it to Nebius Israel.
When you create a Windows boot disk image, specify this in the operating system type. This is important for proper CPU emulation and calculating resource usage costs.
If you regularly update your images, you can group them into families. You can use the family name to find the latest image in the family.
All images belonging to the same family must be in the same folder.
Let's assume you want to upload an image of your operating system to Nebius Israel. When creating an image, specify a family, such as
best-linux-distro. This will allow other users to get the latest version of your operating system by specifying the family and image folder ID in the request.
Public images are, for example, products and solutions from Cloud Marketplace.
You can learn how to get a list of public images here.
To make your image available to other Nebius Israel users, grant them public access to it. To do this, assign the
compute.images.user role to the
allAuthenticatedUsers system group. However, the
compute.images.user role does not grant permission to delete or edit your image.
Images optimized for deployment
The feature is at the Preview stage.
An image can be optimized for deploying a large number of VMs. You can create VMs from optimized images much faster than from conventional ones: this enables you to instantly expand your computing power and use tools from your own image.
Fast deployment is achieved by using multiple layers for storing data in a storage. The first layer stores the image source data, while the second one stores user data. When creating VM disks from optimized images, the first layer is reused rather than copied to a new storage location every time. Disks created from optimized images run on VMs in the same way as disks created from regular images: they can be used as boot disks and are fully available for data storage. The performance of these disks does not differ from that of regular ones.
Regular images from Cloud Marketplace are already optimized for deployment. To optimize your image, select the Optimize for deployment option when uploading the image.
