Hello, are you planning to have all the possible containers loaded on the device, but just stop and start them dynamically by your edge-manager container service? You might be able to use the on-device Supervisor API, specifically the start-service and stop-service endpoints: Interacting with the balena Supervisor - Balena Documentation - in this case you would have to keep in mind the restart policy for the container. (See Stopped containers keep restarting - #18 by 20k-ultra)
Approximately how many containers in total are you contemplating?
