Boot source configuration determines how your instance starts and what storage it uses. The platform supports multiple boot source types with regional variations in features and capabilities.
Deploy from platform operating system images with automatic boot volume creation, or deploy from your existing bootable volumes that appear in the OS Images selection.
Operating system: Selected image installed on new volume
Additional storage: Optional data volumes can be created or attached
Advanced Tier - User Volume:
Boot volume: Existing volume with fixed size
Operating system: Pre-installed on selected volume
Additional storage: Optional data volumes can be created or attached (excluding the boot volume)
Volume exclusion: Selected volume automatically excluded from Attach Volumes
Legacy Tier:
Boot volume: Fixed 100 GB standard storage
Operating system: Selected image installed on new volume
Additional storage: Managed separately in Volumes section
Option 2: Boot from Existing Volume (Legacy Tier)#
Use a previously created bootable volume as your boot source via the Volumes tab. In Legacy tier regions, the Volumes tab provides a dropdown to select from your existing bootable volumes.
When booting from existing volume via Volumes tab:
Boot volume: Existing volume with fixed size
Operating system: Pre-installed on selected volume
SSH keys: Not configured during deployment (already on volume)
Startup scripts: Not applicable (volume already configured)
Data volumes: Managed separately in Volumes section (Legacy tier)
Option 3: Create Data Volumes (Advanced Tier — Volumes Tab)#
In Advanced tier regions, the "Volumes" tab is used to create and manage new data volumes that will be provisioned alongside your instance during deployment. This tab does not provide bootable volume selection — bootable volumes are selected through the OS Images tab.
