kubectl get pod -w

  -w, --watch=false: After listing/getting the requested object, watch for changes. Uninitialized
objects are excluded if no object name is provided.
      --watch-only=false: Watch for changes to the requested object(s), without listing/getting
first.

它类似于linux的watch命令；在list或get一个资源对象后，加上该选项，能够看到它状态的变化。
