ANSIBLE16(template)

botang

用debug模块来测试jinja2语法：

1. ansible srvgroup -m debug -a "msg={{ 101 | random }}"
   
2. ansible srvgroup -m debug -a "msg={{ [1,2,3,4,5] | min }}"
   
3. ansible srvgroup -m debug -a "msg={{ [1,2,3,4,5] | zip(['a','b','c','d','e']) | list }}"
   
4. ansible srvgroup -m debug -a "msg={{ [1,2,3,4,5] | zip(['a','b','c','d','e']) | list | to_nice_yaml }}"
   
5. ansible  localhost -m debug -a "msg={{ 'redhat' | password_hash('sha512')}}"
