Uninstalling Litmus

Chaos Infrastructure​

To disconnect the Chaos Infrastructure connected to the ChaosCenter, follow these steps -

  1. Remove the ChaosEngines of the respective Chaos Infrastructure
kubectl delete chaosengine <CHAOSENGINE_NAMEs> --all -<INFRA_NAMESPACE>
note

If ChaosEngines is unable to delete successfully then the Kubernetes finalizers need to be removed manually.

  1. Login to the ChaosCenter and navigate to the Chaos Infrastructures Page.

  2. Click on the three dot menu and select Disable of the respective Chaos Infrastructure you want to disconnect.

  3. On the Modal that appears, confirm your selection by clicking Yes and the selected Chaos Infrastructure would be disconnected from the ChaosCenter.

    note

    The above disconnect would remove the subscriber component from Chaos Infrastructure and thus removing the connectivity between the Chaos Infrastructure and the ChaosCenter.

    If the Chaos Infrastructure is not reachable it would remove only the entry from the database of the ChaosCenter
