How can we add (programmatically) our own config to a BalenaOS image before writing it to an SD card? The config would need to be read by our container. This could be via a file to the
/data directory or adding an environment variable, or some other solution.
We investigating if Balena is the right solution for a new project. We’d like users of our web-based application to be able to download an image to write to an SD card with Etcher and then put into their own Raspberry Pi. We can generate the “base image” from BalenaCloud and we just need to find a way to link the image that our users download back to their account with us without them doing anything other than writing to to an SD and connecting up a Raspberry Pi (with Ethernet for the internet connection).
I hope that makes sense? Thanks for your help.
