Preloader

The preloader should receive incoming customer orders for provisioning hardware with software. The server will provide the following services:

• Storage, for balena fleet and custom OS images
• Local web server for serving images to HoD EPs
• Preloading utility, via balena cli, to configure images with pinned OS versions and application releases

An example payload from the web shop might look as follows:

[
    {
        orderId: "00001",
        deviceType: "SDcard"
        image: {
            type: "custom"
            url: "https://customer.com/example-image.img.tar.gz",
            authentication: {
                user: "username",
                pass: "password"
            }
        }
    },
    {
        orderId: "00002",
        deviceType: "SDcard",
        image: {
            type: "balena"
            os: "latest",
            release: "72739727a045b0fa999c0be5839f7b91",
            config: {
                network: [
                    { ssid: "network-ssid", psk: "network-password" }
                ]
                name: "device-name",
                ...
            }
        }
    }
]

Local images

The preload server should cache images for a period of X days before automatically removing them to free space.

These images will be available to the local network, with authentication, such that an EtcherPro may download the images for use.
