# WARNNING: 此脚本还在修改中，还未完成
# 说明：不同k8s版本使用的'api-versions'版本不同，此脚本用于切换yaml文件使用的'api-versions'
# Example 01: 转换单个配置文件为k8s 1.8的版本
#  bash tools/trans_yml.sh -v 1.8 -f manifests/dashboard/kubernetes-dashboard.yaml
# Example 02: 转换某个目录下所有yaml文件为k8s 1.8的版本
#  for YML in `find manifests/heapster/ -name '*.yaml'`;do bash tools/trans_yml.sh -v 1.8 -f $YML;done;
