Scaleway Bootscript: Simple Kernel Management for your C1 server
Bootscripts let you choose the kernel version your C1 server uses (but – teasing time – also the boot and initrd arguments, though this is not yet really useful).
A dozen of bootscripts are currently available. You can list them from
your control panel and checkout the sources from our
GitHub repository.
Images bootscripts
When you create a server on Scaleway, you need to select an image. It can be a distribution (Ubuntu, Fedora, ...), an image from the ImageHub (Wordpress, Torrents, ...), or your own (handcrafted!) image.
Each image has a default bootscript. For instance, the current Ubuntu image is associated with the bootscript 3.2.34-std #30 (stable), with, as you probably guessed, a Linux kernel version 3.2.34.
You can display and change the bootscript used by your image directly from the control panel:
- Click on Images in the left side menu
- Select the image you want to show or edit the bootscript
- Click SHOW in the advanced options section to display the bootscript menu
This way, everytime you boot a server using this image, it will use by default the bootscript you just set.
Another way to view the bootscript used by an image is to use our
API:
