     5  Add memory pressure or CPU load to the system.
     6  
     7  ```
     8  kbcli fault stress [flags]
     9  ```
    10  
    11  ### Examples
    12  
    13  ```
    14    # Affects the first container in default namespace's all pods.Making CPU load up to 50%, and the memory up to 100MB.
    15    kbcli fault stress --cpu-worker=2 --cpu-load=50 --memory-worker=1 --memory-size=100Mi
    16    
    17    # Affects the first container in mycluster-mysql-0 pod. Making the CPU load up to 50%, and the memory up to 500MB.
    18    kbcli fault stress mycluster-mysql-0 --cpu-worker=2 --cpu-load=50
    19    
    20    # Affects the mysql container in mycluster-mysql-0 pod. Making the memory up to 500MB.
    21    kbcli fault stress mycluster-mysql-0 --memory-worker=2 --memory-size=500Mi  -c=mysql
    22  ```
    23  
    24  ### Options
    25  
    26  ```
    27        --annotation stringToString      Select the pod to inject the fault according to Annotation. (default [])
    28    -c, --container stringArray          The name of the container, such as mysql, prometheus.If it's empty, the first container will be injected.
    29        --cpu-load int                   Specifies the percentage of CPU occupied. 0 means no extra load added, 100 means full load. The total load is workers * load.
    30        --cpu-worker int                 Specifies the number of threads that exert CPU pressure.
    31        --dry-run string[="unchanged"]   Must be "client", or "server". If with client strategy, only print the object that would be sent, and no data is actually sent. If with server strategy, submit the server-side request, but no data is persistent. (default "none")
    32        --duration string                Supported formats of the duration are: ms / s / m / h. (default "10s")
    33    -h, --help                           help for stress
    34        --label stringToString           label for pod, such as '"app.kubernetes.io/component=mysql, statefulset.kubernetes.io/pod-name=mycluster-mysql-0. (default [])
    35        --memory-size string             Specify the size of the allocated memory or the percentage of the total memory, and the sum of the allocated memory is size. For example:256MB or 25%
    36        --memory-worker int              Specifies the number of threads that apply memory pressure.
    37        --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")
    38        --node stringArray               Inject faults into pods in the specified node.
    39        --node-label stringToString      label for node, such as '"kubernetes.io/arch=arm64,kubernetes.io/hostname=minikube-m03,kubernetes.io/os=linux. (default [])
    40        --ns-fault stringArray           Specifies the namespace into which you want to inject faults. (default [default])
    41    -o, --output format                  Prints the output in the specified format. Allowed values: JSON and YAML (default yaml)
    42        --phase stringArray              Specify the pod that injects the fault by the state of the pod.
    43        --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.
    44  ```

    48  ```
    49        --as string                      Username to impersonate for the operation. User could be a regular user or a service account in a namespace.
    50        --as-group stringArray           Group to impersonate for the operation, this flag can be repeated to specify multiple groups.

    63        --request-timeout string         The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests. (default "0")
    64    -s, --server string                  The address and port of the Kubernetes API server
    65        --tls-server-name string         Server name to use for server certificate validation. If it is not provided, the hostname used to contact the server is used
