Интервал кубе-обезьяны (тестирование хаоса)

Если вы видите официальную диаграмму helm values.yaml, там нет ключа interval. так как вы сохранили schedule_immediate_kill : TRUE время уничтожения по умолчанию будет 30S

https://github.com/asobti/kube-monkey/blob/master/helm/kubemonkey/values.yaml

вы можете изменить время интервала, используя schedule_delay

[debug]
enabled = true
schedule_delay=30
force_should_kill = true
schedule_immediate_kill = true

вместо interval используйте schedule_delay.

однако интервал работает с Kubethanos: https://jaxenter.com/kubernetes-chaos-kubethanos-164798.html вы можете передать ключ-значение в качестве параметра.

Файл параметров golang покажет нам, какие конфигурации мы можем изменить: https://raw.githubusercontent.com/asobti/kube-monkey/master/config/param/param.go
