Ubicloud Machine Images let you capture a virtual machine’s disk as a reusable, versioned image and boot new VMs from it. You can install dependencies, apply configuration, and prepare data once, then launch identical VMs from the resulting image.

​
Versions

An image can have multiple versions. One version can be designated the image’s latest version. It is used when a VM requestsimage-name@latest.

​
Booting a VM from an image

When creating a VM, you can select a machine image as its boot image and choose either a specific version or the latest version. The image and VM must be in the same location.
The web console currently supports booting only from the latest version. To boot from a specific version, use the CLI.

​
Limitations

The source VM must meet the following requirements:
  • Stopped: Stop the VM before capturing an image or version from it.
  • Disk size: The VM must have a single disk no larger than 40 GiB.
