image cloud publique OVH

The most popular system images and pre-installed applications

In order to get your systems up and running as quickly as possible, OVH offers the industry-standard cloud images, as well as the most popular pre-installed applications.

Maintained by OVH

The images are produced and maintained by OVH. You do not have to worry about providing the classic system images, and updates are also provided by us.

Optimised for the OVH infrastructure

The system images provided are specifically configured to make the most of the OVH infrastructure. You enjoy the full performance offered by the instance. 

Quick startup

System images from the Public Image Catalog are systematically cached on all hypervisors, so cloud servers start up in seconds. 

On-the-fly configuration

Thanks to the "cloud-init" startup scripts, each instance can have a specific behaviour while still being based on a standard image. Cloud-init allows you to configure an infinite number of parameters and also launch scripts to customise each instance startup.

Pricing Public Cloud

Public Image Catalog billing

The Public Image Catalog offers system images for free. However, some of them may require a license.

What SLA does OVHcloud offer for accessing the Public Image Catalog service?

The SLA guarantees 99.9% monthly availability for accessing the Public Image Catalog service.

Are the images official?

When cloud images are offered by publishers, OVHcloud delivers them as they are. This means you get exactly the same behaviour as you would from other providers who use the same images. When the publisher does not provide a cloud image, we build custom images to work properly in the OVHcloud environment.

What is cloud-init?

Cloud-init is software installed on cloud images. It manages a certain number of primitives when an instance is booted, depending on its environment and “personality”. This personality is defined by parameters such as its name, its network and disk configurations, and customisation scripts that offer flexible automation. Cloud-init manages script formats like bash, and others that are more appropriate, such as cloud-config.

Where can I find documentation on cloud-init and cloud-config syntax?

Although the cloud-config syntax is simple, you may need documentation to set advanced configurations. You can find it here.

How do I update my operating system?

Once the instance has been deployed, you are responsible for maintaining your operating system. Even if OVHcloud updates its images, this does not affect instances that have already been deployed. You can use the standard system update channels on your instance.

I can't find the image I want in the list of images offered. What can I do?

OVHcloud provides a list of images for the most common uses. You may need something more specific. If this is the case, you can push a system image of your choice into the Private Image Catalog.

Will OVHcloud have access to my operating system if I use the images offered?

No, you are the sole administrator of your machine. OVHcloud does not have any access to your operating system.

What is a cloud image?

A cloud image is a single file with a virtual disk containing an operating system to install. This installation is made generic, so that it can be copied before running in a particular context when the user needs it. Most often, these are Linux or Windows installations.
