The Bring Your Own Image technology (BYOI) enables you to deploy cloudready images directly on your dedicated server. You can therefore use the bare metal service as a resource for your deployments.
What does cloudready mean?
In short, to be agnostic of the infrastructure on which the image is deployed. In addition to the prerequisites and limitations mentioned below, you must ensure that the image (downloaded or generated) answers correctly to the definition of technical expectations of a cloudready image. The image must be able to boot correctly, whatever the server type, it must also embed the Cloud-Init service if Config Drive is used. Finally, the system configurations must allow the OS to be fully initiated, especially those related to the network.
You can also make use of this option when reinstalling a server from the OVHcloud Control Panel. Please use the instructions below as a reference. This guide explains how to use the BYOI feature in the OVHcloud Control Panel.
There are some technical limitations linked to the use of physical products such as dedicated servers. Here is a non-exhaustive list, to keep in mind during your deployment preparation:
- Boot type : uefi or legacy
- Partition type : MBR or GPT
- Image format : qcow2 or raw
If your server has a uefi boot type, be sure to add an EFI partition to your image template.
