问题描述
是否有一种简单的方法可以将Openstack show命令输出转换为openstack命令？ 目标是在完全擦除后重建开放堆栈环境。
（例如：openstack network show myNet> out.txt， 然后以out.txt为基础，以某种方式生成带有适当字段的Openstack CLI命令，以重新创建相同的确切网络？
谢谢！
解决方法
您可以将show命令的输出作为json格式的字符串写入文件，因此您可以轻松地使用python-script读取输出的信息以创建并执行所需的命令。
要将openstack命令的输出打印为json，请在命令末尾添加-f json。
示例：
openstack server show cirros -f json
