# Chaotic - Chaos for Clouds
Chaotic evaluates a plan, how it will bring chaos in your Cloud environment.
Depending on the Cloud API used, it may kill allocations (Hashicorp Nomad), reboot or stop/start virtual machines in your Cloud environment.
With no arguments given, Chaotic runs as a "one shot" meant to be executed as cron job. Passing `--periodic` runs it as daemon with configurable mintute intervals `--interval 5` (1 is the default).
Note: The config is re-read on every interval, no need to restart the service after a config change.
## Clouds
Currently implemented Clouds:
- DigitalOcean
- Vultr
- Hetzner Cloud
- Proxmox KVM
- CloudStack
- Hashicorp Nomad
- Exoscale
- cloudscale.ch
## Install
```
pip3 install -U chaotic-ngine
```
## Configure
Create a file named `config.yaml` or use the env var `CHAOTIC_CONFIG` to point to a config file (also see the example directory):
```
export CHAOTIC_CONFIG=config_nomad.yaml
```
