1. minikube status

查看一个集群的状态

Exit status contains the status of minikube's VM, cluster and Kubernetes encoded on it's bits in this order from right to left.

Eg: 7 meaning: 1 (for minikube NOK) + 2 (for cluster NOK) + 4 (for Kubernetes NOK)

1.1. Options

  -f, --format string         Go template format string for the status output.  The format for Go templates can be found here: https://golang.org/pkg/text/template/

  -l, --layout string         output layout (EXPERIMENTAL, JSON only): 'nodes' or 'cluster' (default "nodes")
  -n, --node string           The node to check status for. Defaults to control plane. Leave blank with default format for status on all nodes.
  -o, --output string         minikube status --output OUTPUT. json, text (default "text")
  -w, --watch duration[=1s]   Continuously listing/getting the status with optional interval duration. (default 1s)

1.2. 从父命令继承的选项

      --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
  -b, --bootstrapper string              The name of the cluster bootstrapper that will set up the Kubernetes cluster. (default "kubeadm")
  -h, --help                             
      --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
      --log_file string                  If non-empty, use this log file
      --log_file_max_size uint           Defines the maximum size a log file can grow to. Unit is megabytes. If the value is 0, the maximum file size is unlimited. (default 1800)
      --logtostderr                      log to standard error instead of files
      --one_output                       If true, only write logs to their native severity level (vs also writing to each lower severity level)
  -p, --profile string                   The name of the minikube VM being used. This can be set to allow having multiple instances of minikube independently. (default "minikube")
      --skip_headers                     If true, avoid header prefixes in the log messages
      --skip_log_headers                 If true, avoid headers when opening log files
