Using balena for local updates

Balena uses Docker containers to deploy software updates. Devices run balenaOS, a Yocto-based Linux distribution that comes with balenaEngine, balena's Docker-compatible container engine. OTA updates occur automatically by way of releases pushed from balenaCloud, a hosted service for managing fleets of devices. Balena can also operate in local mode so that updates originate from a server running on your local host machine rather than the cloud. We will stick to local mode for the following exercises.

Balena is written and supported by balena.io (https://balena.io). There is much more information about the software in the Reference section of the online Docs at balena.io. We won't dig into how balena works since our goal is to deploy and automatically update software on a small fleet of devices for fast development.

Balena provides prebuilt balenaOS images for popular dev boards such as the Raspberry Pi 4 and BeagleBone Black. Downloading...
