    30    kbcli fault pod kill --ns-fault="default"
    31    
    32    # --label is required to specify the pods that need to be killed.
    33    kbcli fault pod kill --label statefulset.kubernetes.io/pod-name=mysql-cluster-mysql-2
    34

    55        --label stringToString           label for pod, such as '"app.kubernetes.io/component=mysql, statefulset.kubernetes.io/pod-name=mycluster-mysql-0. (default [])
    56        --mode string                    You can select "one", "all", "fixed", "fixed-percent", "random-max-percent", Specify the experimental mode, that is, which Pods to experiment with. (default "all")
    57        --node stringArray               Inject faults into pods in the specified node.
    58        --node-label stringToString      label for node, such as '"kubernetes.io/arch=arm64,kubernetes.io/hostname=minikube-m03,kubernetes.io/os=linux. (default [])
    59        --ns-fault stringArray           Specifies the namespace into which you want to inject faults. (default [default])
    60    -o, --output format                  Prints the output in the specified format. Allowed values: JSON and YAML (default yaml)
    61        --phase stringArray              Specify the pod that injects the fault by the state of the pod.
    62        --value string                   If you choose mode=fixed or fixed-percent or random-max-percent, you can enter a value to specify the number or percentage of pods you want to inject.
