Container image format

When using a container registry, the container image must contain the following two files in the root of the image:

  • firmware.bin - This is the firmware artifact to be delivered

  • firmware.json - This is a manifest with metadata of the firmware

An example firmware.json manifest looks like this:

  "version": "2dbedf0",
  "size": 7716,
  "checksum": "2e8db6036411adccba75dd5a0316e6ab72402351478a35ac5a452d4cf6371c8f"

As long as these two files are present, Drogue Ajour will be able to deliver the firmware to devices.
