### Synopsis

Register a cluster to Karmada control plane with Push mode.

```
karmadactl join CLUSTER_NAME --cluster-kubeconfig=<KUBECONFIG>
```

### Examples

```
  # Join cluster into karmada control plane, if '--cluster-context' not specified, take the cluster name as the context
  karmadactl join CLUSTER_NAME --cluster-kubeconfig=<KUBECONFIG>
```

### Options

```
      --cluster-context string         Name of cluster context in kubeconfig. The current context is used by default.
      --cluster-kubeconfig string      Path of the cluster's kubeconfig.
      --cluster-namespace string       Namespace in the control plane where member cluster secrets are stored. (default "karmada-cluster")
      --cluster-provider string        Provider of the joining cluster. The Karmada scheduler can use this information to spread workloads across providers for higher availability.
      --cluster-region string          The region of the joining cluster. The Karmada scheduler can use this information to spread workloads across regions for higher availability.
      --cluster-zones strings          The zones of the joining cluster. The Karmada scheduler can use this information to spread workloads across zones for higher availability.
      --dry-run                        Run the command in dry-run mode, without making any server requests.
  -h, --help                           help for join
      --karmada-as string              Username to impersonate for the operation in karmada control plane. User could be a regular user or a service account in a namespace.
      --karmada-as-group stringArray   Group to impersonate for the operation in karmada control plane, this flag can be repeated to specify multiple groups.
      --karmada-as-uid string          UID to impersonate for the operation in karmada control plane.
      --karmada-context string         The name of the kubeconfig context to use

### Options inherited from parent commands

```
      --add-dir-header                   If true, adds the file directory to the header of the log messages
      --alsologtostderr                  log to standard error as well as files (no effect when -logtostderr=true)
      --log-backtrace-at traceLocation   when logging hits line file:N, emit a stack trace (default :0)
      --log-dir string                   If non-empty, write log files in this directory (no effect when -logtostderr=true)
      --log-file string                  If non-empty, use this log file (no effect when -logtostderr=true)
      --log-file-max-size uint           Defines the maximum size a log file can grow to (no effect when -logtostderr=true). Unit is megabytes. If the value is 0, the maximum file size is unlimited. (default 1800)
      --logtostderr                      log to standard error instead of files (default true)
      --one-output                       If true, only write logs to their native severity level (vs also writing to each lower severity level; no effect when -logtostderr=true)
      --skip-headers                     If true, avoid header prefixes in the log messages
      --skip-log-headers                 If true, avoid headers when opening log files (no effect when -logtostderr=true)
      --stderrthreshold severity         logs at or above this threshold go to stderr when writing to files and stderr (no effect when -logtostderr=true or -alsologtostderr=true) (default 2)
  -v, --v Level                          number for the log level verbosity
      --vmodule moduleSpec               comma-separated list of pattern=N settings for file-filtered logging
