Base Image Collections
As mentioned in the OTA Update concepts, Base Image Collection represent a set of Base Images associated with a specific System Model and, implicitly via the System Model, with a specific Hardware Type. The mapping relation between Base Image Collection and System Models is 1:1, so a Base Image Collection is associated with a single System Model and viceversa.
A Base Image Collection contains all the Base Images that ran, are running or could be run on a System Model. Drawing from the bike sharing example, there would be a different Base Image Collection for, e.g., e-bikes from each specific country to handle the different speed limitations.
The primary purpose of a Base Image Collection is to limit what can be installed to a System Model, preventing unintended installations, such as electric scooter firmware on an e-bike.
In Edgehog a Base Image Collection has this information associated with it:
- Name: a user friendly name used to identify the Base Image Collection (e.g. "E-Scooter OS")
- Handle: a machine friendly identifier for the Base Image Collection (e.g. "e-scooter-os"). A valid handle
must begin with a lowercase letter followed by any number of lower case letters, numbers or dashes (
-). - System Model: the System Model that is associated with this Base Image Collection.
- Base Images: a set of Base Images associated with this Base Image Collection.
