Installer Images
Images allow you to create an installable image for an Asset that can be downloaded and flashed to an USB drive using balenaEtcher.
This is useful for installing on bare metal by booting from the USB drive. The same image can be used for all Assets in the same Fleet. The installation process will install the OS, K3s, the ECP Management Service and create a new Asset in Studio. You can access Images by expanding the EdgeOps section.
