    11  ### Examples
    12  
    13  ```
    14    // Inject DNS faults into all pods under the default namespace, so that any IP is returned when accessing the bing.com domain name.
    15    kbcli fault dns random --patterns=bing.com --duration=1m
    16    
    17    // Inject DNS faults into all pods under the default namespace, so that error is returned when accessing the bing.com domain name.
    18    kbcli fault dns error --patterns=bing.com --duration=1m
    19  ```

    28        --label stringToString           label for pod, such as '"app.kubernetes.io/component=mysql, statefulset.kubernetes.io/pod-name=mycluster-mysql-0. (default [])
    29        --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")
    30        --node stringArray               Inject faults into pods in the specified node.
    31        --node-label stringToString      label for node, such as '"kubernetes.io/arch=arm64,kubernetes.io/hostname=minikube-m03,kubernetes.io/os=linux. (default [])
    32        --ns-fault stringArray           Specifies the namespace into which you want to inject faults. (default [default])
    33    -o, --output format                  Prints the output in the specified format. Allowed values: JSON and YAML (default yaml)
    34        --patterns stringArray           Select the domain name template that matching the failure behavior & supporting placeholders ? and wildcards *.
    35        --phase stringArray              Specify the pod that injects the fault by the state of the pod.
    36        --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.
