# Galileo FaaS

This project aims to provide easy to use functions to monitor a running K3S cluster, including telemetry data and
traces. The provided functions can help to build intelligent runtime optimizations, i.e., load balancing or scheduling
strategies.

For this environment to work, you need to have the following setup:

* a running K3S cluster
* an etcd instance
* redis for storing nodeinfos and as pub/sub framework
* [telemd](https://github.com/edgerun/telemd/) daemons deployed to monitor resource usage
* [telemd-kubernetes-adapter](https://github.com/edgerun/telemd-kubernetes-adapter) daemon deployed in the Kubernetes
  cluster that monitors all Pods an emits events upon changes.

In case you want to start a full-fledged experiment with [galileo](https://github.com/edgerun/galileo), you will also
need:

* InfluxDB to store telemetry, traces and events
* MariaDB for experiment metadata

Visit the [galileo-experiments](https://github.com/edgerun/galileo-experiments)  project to get further information on
setting up an experiment environment.

### Example

Look for an example on how to quickly start all services under `galileofaas.cli.main`.
