title: kbcli fault network corrupt Distorts the messages a pod communicates with other objects. ``` kbcli fault network corrupt [flags] ``` ``` kbcli fault network partition kbcli fault network partition mycluster-mysql-1 --external-targets=kubeblocks.io kbcli fault network partition mycluster-mysql-1 --target-label=statefulset.kubernetes.io/pod-name=mycluster-mysql-2 // Like the partition command, the target can be specified through --target-label or --external-targets. The pod only has obstacles in communicating with this target. If the target is not specified, all communication will be blocked. kbcli fault network loss --loss=50 kbcli fault network loss mysql-cluster-mysql-2 --loss=50 kbcli fault network corrupt --corrupt=50 kbcli fault network corrupt mysql-cluster-mysql-2 --corrupt=50 kbcli fault network duplicate --duplicate=50 kbcli fault network duplicate mysql-cluster-mysql-2 --duplicate=50 kbcli fault network delay --latency=10s kbcli fault network delay mysql-cluster-mysql-2 --latency=10s kbcli fault network bandwidth mysql-cluster-mysql-2 --rate=1kbps --duration=1m ``` ``` --annotation stringToString Select the pod to inject the fault according to Annotation. (default []) -c, --correlation string Indicates the correlation between the probability of a packet error occurring and whether it occurred the previous time. Value range: [0, 100]. --corrupt string Indicates the probability of a packet error occurring. Value range: [0, 100]. --direction string You can select "to"" or "from"" or "both"". (default "to") --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") -e, --external-target stringArray a network target outside of Kubernetes, which can be an IPv4 address or a domain name, such as "www.baidu.com". Only works with direction: to. -h, --help help for corrupt --label stringToString label for pod, such as '"app.kubernetes.io/component=mysql, statefulset.kubernetes.io/pod-name=mycluster-mysql-0. (default []) --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

Allowed values: JSON and YAML (default yaml) --phase stringArray Specify the pod that injects the fault by the state of the pod. --target-label stringToString label for pod, such as '"app.kubernetes.io/component=mysql, statefulset.kubernetes.io/pod-name=mycluster-mysql-0"' (default []) --target-mode string You can select "one", "all", "fixed", "fixed-percent", "random-max-percent", Specify the experimental mode, that is, which Pods to experiment with. --target-ns-fault stringArray Specifies the namespace into which you want to inject faults. --target-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. --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. ``` ``` --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 ``` - Network chaos.
