My docker-lifx-daydusk project attempts to solve two usability concerns with the Day & Dusk functionality built-into the LIFX app: it does not require a connection to the LIFX Cloud and it provides more configurable options for each scheduled transition event.
In order to facilitate simple scanning of Docker and Rkt images based on Oracle Linux, I added support for Oracle Linux to both Clair and Vuls (VULnerability Scanner).
