AWS IoT Greengrass runtime for constrained devices.
The Greengrass Nucleus Lite provides a smaller alternative to the Classic nucleus for Greengrass v2 deployments.
Greengrass Nucleus Lite aims to maintain compatibility with the Classic nucleus, and implements a subset of its functionality.
See the build guide for instructions to build and install Greengrass Nucleus Lite from source.
To configure and run Greengrass Nucleus Lite, see the setup guide.
For setting up as a Greengrass developer, also see the developer setup guide.
