Container Scenarios using Krkn
Example Config
The following are the components of Kubernetes for which a basic chaos scenario config exists today.
scenarios:
- name: "<name of scenario>"
namespace: "<specific namespace>" # can specify "*" if you want to find in all namespaces
label_selector: "<label of pod(s)>"
container_name: "<specific container name>" # This is optional, can take out and will kill all containers in all pods found under namespace and label
pod_names: # This is optional, can take out and will select all pods with given namespace and label
- <pod_name>
count: <number of containers to disrupt, default=1>
action: <kill signal to run. For example 1 ( hang up ) or 9. Default is set to 1>
expected_recovery_time: <number of seconds to wait for container to be running again> (defaults to 120seconds)
How to Use Plugin Name
Add the plugin name to the list of chaos_scenarios section in the config/config.yaml file
