Pod Scenarios using Krkn
Example Config
The following are the components of Kubernetes for which a basic chaos scenario config exists today.
kraken:
chaos_scenarios:
- plugin_scenarios:
- path/to/scenario.yaml
You can then create the scenario file with the following contents:
# yaml-language-server: $schema=../plugin.schema.json
- id: kill-pods
config:
namespace_pattern: ^kube-system$
label_selector: k8s-app=kube-scheduler
krkn_pod_recovery_time: 120
Please adjust the schema reference to point to the schema file. This file will give you code completion and documentation for the available options in your IDE.
