(default []) -c, --container stringArray The name of the container, such as mysql, prometheus.If it's empty, the first container will be injected. --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") --duration string Supported formats of the duration are: ms / s / m / h. (default "10s") --filling string The filling content of the error data can only be zero (filling with 0) or random (filling with random bytes). -h, --help help for mistake --label stringToString label for pod, such as '"app.kubernetes.io/component=mysql, statefulset.kubernetes.io/pod-name=mycluster-mysql-0. (default []) --max-length int The maximum length (in bytes) of each error. (default 1) --max-occurrences int The maximum number of times an error can occur per operation. (default 1) --method stringArray The file system calls that need to inject faults. For example: WRITE READ --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") --node stringArray Inject faults into pods in the specified node. --node-label stringToString label for node, such as '"kubernetes.io/arch=arm64,kubernetes.io/hostname=minikube-m03,kubernetes.io/os=linux. (default []) --ns-fault stringArray Specifies the namespace into which you want to inject faults. (default [default]) -o, --output format Prints the output in the specified format. Allowed values: JSON and YAML (default yaml) --path string The effective scope of the injection error can be a wildcard or a single

--percent int Probability of failure per operation, in %. (default 100) --phase stringArray Specify the pod that injects the fault by the state of the pod. --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. --volume-path string The mount point of the volume in the target container must be the root directory of the mount. ``` ``` --as string Username to impersonate for the operation. User could be a regular user or a service account in a namespace. --as-group stringArray Group to impersonate for the operation, this flag can be repeated to specify multiple groups. --as-uid string UID to impersonate for the operation. --cache-dir string Default cache directory (default "$HOME/.kube/cache") --certificate-authority string Path to a cert file for the certificate authority --client-certificate string Path to a client certificate file for TLS --client-key string Path to a client key file for TLS --cluster string The name of the kubeconfig cluster to use --context string The name of the kubeconfig context to use --disable-compression If true, opt-out of response compression for all requests to the server --insecure-skip-tls-verify If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure --kubeconfig string Path to the kubeconfig file to use for CLI requests. --match-server-version Require server version to match client version -n, --namespace string If present, the namespace scope for this CLI request --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") -s, --server string The address and port of the Kubernetes API server --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 --token string Bearer token for authentication to the API server --user string The name of the kubeconfig user to use ``` - IO chaos.
