Nebula container orchestrator
- 1. Nebula Container Orchestrator Manging IoT deployments with Docker containers https://nebula-orchestrator.github.io/ Naor Livne
- 2. IoT orchestration difficulties • IoT devices are often distributed • IoT are often low powered • Code is copled to hardware - no packing multiple apps to same device • Network uptimespeed is often not guaranteed • Huge scale is common - deployments of tens of thousands of devices is considerd common
- 3. Nebula features • Designed to scale out on all of it's components (IoT devices, API layer, RabbitMQ & Mongo all scale out) • Able to manage tens of thousands of IoT devices • Latency tolerant - even if a device goes offline he will be resynced when he gets back online • Dynamically add/remove managed devices • Fast & easy code deployments, single API call with the new container image tag and it will be pushed to all devices of that app. • Simple install - RabbitMQ, MongoDB, a stateless API is all it takes for the mangment layer & a single container with some envvars on each IoT device you want to manage takes care of the worker layer • Single API endpoint to manage all devices • Allows control of multiple devices with the same Nebula orchestrator (multiple apps) • Not limited to IoT, also useful for other types of distributed systems • API, Python SDK & CLI control available
- 5. Installing nebula 1. Install RabbitMQ - any configuration works 2. Install MongoDB - any configuration works 3. Install the stateless API by running a container of it with the following envvars: • BASIC_AUTH_USER • BASIC_AUTH_PASSWORD • RABBIT_HOST • RABBIT_PORT • RABBIT_USER • RABBIT_PASSWORD • RABBIT_VHOST • MONGO_URL • ... any other config option you need
- 6. Nebula - adding devices Run the nebula worker container with the following envvarsconfig file variables (make sure to set it with the --restart flag): • APP_NAME - comma sperated list what apps (services) run on said workers • RABBIT_HOST - the RabbitMQ host • RABBIT_PORT - the RabbitMQ port • RABBIT_USER - the RabbitMQ user • RABBIT_PASSWORD - the RabbitMQ pass • RABBIT_VHOST - the RabbitMQ vhost • MONGO_URL - mongo URI string • ... any other config option you need
- 7. Nebula - API examples create a new app: Update app: Releasing a new version is just a matter of an Update API call with the new "docker_image" param & all devices will be updated
