karmada-descheduler

Synopsis

The karmada-descheduler evicts replicas from member clusters if they are failed to be scheduled for a period of time. It relies on karmada-scheduler-estimator to get replica status.

karmada-descheduler [flags]

Options

      --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)
      --bind-address string                         The IP address on which to listen for the --secure-port port. (default "0.0.0.0")
      --descheduling-interval duration              Time interval between two consecutive descheduler executions. Setting this value instructs the descheduler to run in a continuous loop at the interval specified. (default 2m0s)
      --enable-pprof                                Enable profiling via web interface host:port/debug/pprof/.
  -h, --help                                        help for karmada-descheduler
      --kube-api-burst int                          Burst to use while talking with karmada-apiserver. Doesn't cover events and node heartbeat apis which rate limiting is controlled by a different set of flags. (default 60)
      --kube-api-qps float32                        QPS to use while talking with karmada-apiserver. Doesn't cover events and node heartbeat apis which rate limiting is controlled by a different set of flags. (default 40)

      --leader-elect                                Enable leader election, which must be true when running multi instances. (default true)
      --leader-elect-resource-namespace string      The namespace of resource object that is used for locking during leader election. (default "karmada-system")
      --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)
      --master string                               The address of the Kubernetes API server. Overrides any value in KubeConfig. Only required if out-of-cluster.
      --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)
      --profiling-bind-address string               The TCP address for serving profiling(e.g. 127.0.0.1:6060, :6060). This is only applicable if profiling is enabled. (default ":6060")
      --scheduler-estimator-port int                The secure port on which to connect the accurate scheduler estimator. (default 10352)
      --scheduler-estimator-service-prefix string   The prefix of scheduler estimator service name (default "karmada-scheduler-estimator")
      --scheduler-estimator-timeout duration        Specifies the timeout period of calling the scheduler estimator service. (default 3s)
      --secure-port int                             The secure port on which to serve HTTPS. (default 10358)
      --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)

      --unschedulable-threshold duration            The period of pod unschedulable condition. This value is considered as a classification standard of unschedulable replicas. (default 5m0s)
  -v, --v Level                                     number for the log level verbosity
      --vmodule moduleSpec                          comma-separated list of pattern=N settings for file-filtered logging
