Usage

See the kubethanos.yaml file for an example run. Here are the list of valid parameters:

--namespaces=!kubesystem,foo-bar // A namespace or a set of namespaces to restrict kubethanos
--included-pod-names=<pod(s)_will_be_selected_if_pod_name_contains_this_string>
--node-names=<pod(s)_will_be_selected_if_they_reside_in_given_node_names>
--excluded-pod-names=<pod(s)_will_be_excluded_if_pod_name_contains_this_string>
--master // The address of the Kubernetes cluster to target, if none looks under $HOME/.kube
--kubeconfig // Path to a kubeconfig file
--healthcheck // Listens this endpoint for healthcheck
--interval // Interval between killing pods
--dry-run // If true, print out the pod names without actually killing them. Defaults *FALSE*
--ratio // ratio of pods to kill. Default is 0.5 
--debug // Enable debug logging.
  • Pods to kill will be searched with a top-down approach. Node(s) first Pod(s) later.
