Deploying containers on Heterogeneous IOT devices by Daniel Bruzual
This document discusses deploying containers on heterogeneous IoT devices using Docker Swarm. It covers initializing a Swarm on IoT devices with different host OS, architectures and sensors. It also discusses using multi-stage Dockerfiles to create compact container images, deploying applications across devices using labels and constraints, and future work including device mounting and secure provisioning.
