Does this modules work with docker images stored in private DockerHub repositories?
Yes it works with private DockerHub repositories as well. For example:
The Update Module itself will just “pull” whatever you have specified in DOCKER_IMAGES.
So as @QuentinVecchio is pointing out, it will work with private registry as long as the device has access to such registry. If the registry requires authentication, the device will need to perform
docker login prior to the containers update.
The source code is very simple, as this module is meant to be easily extensible. So do not hesitate to do you own extensions and share them back to the community
