Uninstalling Litmus
Chaos Infrastructure​
To disconnect the Chaos Infrastructure connected to the ChaosCenter, follow these steps -
Remove the ChaosEngines of the respective Chaos Infrastructure
kubectl delete chaosengine <CHAOSENGINE_NAMEs> --all -<INFRA_NAMESPACE>
If ChaosEngines is unable to delete successfully then the Kubernetes finalizers need to be removed manually.
Login to the ChaosCenter and navigate to the Chaos Infrastructures Page.
Click on the three dot menu and select
Disable
of the respective Chaos Infrastructure you want to disconnect.On the Modal that appears, confirm your selection by clicking
Yes
and the selected Chaos Infrastructure would be disconnected from the ChaosCenter.note
