After installing the latest Stretch image of Raspbian as provided here, is 1.3GB left of Flash memory and 2.7GB used (4GB total). This does not leave much room for updates and software to be installed on the device. Currently I am not using any of the IO or gateway modules (but that might change in the future), so my question is what packages should/could I remove and how to restructure the installation to have a lighter footprint on the disk?
I want to install the Azure IoT Edge packages that require python and docker (Moby) to be installed, and most things else are in the "nice-to-have" category.
Azure IoT Edge works by installing software as docker-modules, that is managed from the Azure IoT Hub in the cloud. These modules would then interface with device and surrounding systems, as required.
