How to create an image from an instance and create a new server from this image
This page shows how to create an image from an instance and create a new server from this image.
Requirements
- You have an account and are logged into console.scaleway.com
- Your SSH key is configured
- You have a running server
- You have installed packages and made the configuration you need on your server
- You have created a snapshot of the volume you want to be an image
Images allow you to create series of servers with predefined configuration.
For instance, you can prepare to scale your serving capacity with a frontend image for an Apache server.
Some potential uses:
- Automate Server Builds
- Create a Software Testing Environment
There are three steps to create an Image:
- Power off your server
- Create an Image
- Verify Image creation
There are three steps to create a server from an Image
- Create an Image from a volume snapshot
- Image creation

There are three steps to create a new server from an image:
- Name your server
- Choose your Image
- Create your server
Create an Image
In the Control Panel, click on Snapshots in the compute section.
Step 1 - Create an Image from a volume snapshot
The page you land on contains the list of your snapshosts.
Select the snapshot to use to create an Image and click “Image from snapshot” button.
Step 2 - Image creation
You are now asked to give a name to your Image and to specify the architecture of the image.
Click the “Create Image” button, your Image is now ready to use.
Step 3 - Verify Image creation
In the Compute section of the console click “Images”. Your new Image should be present in the Images list.
Create a server from your own image
In the previous steps, we created a new Image. We will create a new server based on the Image we previously created.
In the Control Panel, click the “Create Server” button.
Step 1 - Name you server
You will land on the server-creation page where you must input basic information for your server.
Step 2 - Choose your Image
In the Image section click the Images tab. Select the Image you created previously from the list below.
Step 3 - Create your server
Click the “Create Server” button. This action starts your server. In a few seconds, your server will be ready to use.
The running server will be an exact copy of your Image.
Please note that you can use your image only on instances using the same CPU architecture. For instance, it is not possible to boot an ARMv8 based image on a X86-64 server.
