Chaotic - Chaos for CloudsChaotic 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--periodicruns 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.CloudsCurrently implemented Clouds:DigitalOceanVultrHetzner CloudProxmox KVMCloudStackHashicorp NomadExoscalecloudscale.chInstallpip3 install -U chaotic-ngineConfigureCreate a file namedconfig.yamlor use the env varCHAOTIC_CONFIGto point to a config file (also see the example directory):export CHAOTIC_CONFIG=config_nomad.yamlExclude timesDefine times when the bot should not doing real actions (it will run in dry-run):---kind:...excludes:weekdays:-Sun-Sattimes_of_day:-22:00-08:00-11:00-14:00days_of_year:-Jan01-Apr01-May01-Aug01-Dec24ExoscaleChaotic will stop a server selected by an optional filter tag and stop/start it with a delay of a configurable time (default 60s).export EXOSCALE_API_KEY="..."
