Kube-monkey interval (Chaos Testing)

If you see the official helm chart values.yaml there is no interval key. since you have kept schedule_immediate_kill : TRUE default kill time will be 30S

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

you can change the interval time using schedule_delay

[debug]enabled = trueschedule_delay=30force_should_kill = trueschedule_immediate_kill = true

instead of interval use the schedule_delay.

however the interval is working with the Kubethanos : https://jaxenter.com/kubernetes-chaos-kubethanos-164798.htmlyou can pass key-value as a parameter.

The params file of golang will show us what all configurations we can alter have a look: https://raw.githubusercontent.com/asobti/kube-monkey/master/config/param/param.go
