Set the scenarios to inject and the tunings like duration to wait between each scenario in the config file located at config/config.yaml. A sample config looks like:
kraken:
kubeconfig_path: /root/.kube/config # Path to kubeconfig
exit_on_failure: False # Exit when a post action scenario fails
chaos_scenarios: # List of policies/chaos scenarios to load
- pod_scenarios: # List of chaos pod scenarios to load
- - scenarios/etcd.yml
- - scenarios/regex_openshift_pod_kill.yml
- scenarios/post_action_regex.py
- node_scenarios: # List of chaos node scenarios to load
- scenarios/node_scenarios_example.yml
- pod_scenarios:
- - scenarios/openshift-apiserver.yml
- - scenarios/openshift-kube-apiserver.yml
- time_scenarios: # List of chaos time scenarios to load
- scenarios/time_scenarios_example.yml
cerberus:
cerberus_enabled: False # Enable it when cerberus is previously installed
cerberus_url: # When cerberus_enabled is set to True, provide the url where cerberus publishes go/no-go signal
performance_monitoring:
deploy_dashboards: False # Install a mutable grafana and load the performance dashboards. Enable this only when running on OpenShift
repo: "https://github.com/cloud-bulldozer/performance-dashboards.git"
tunings:
wait_duration: 60 # Duration to wait between each chaos scenario
iterations: 1 # Number of times to execute the scenarios
daemon_mode: False # Iterations are set to infinity which means that the kraken will cause chaos forever
NOTE: config can be used if leveraging the automated way to install the infrastruture pieces.
