ANSIBLE16(template)
用debug模块来测试jinja2语法：ansible srvgroup -m debug -a "msg={{ 101 | random }}"
ansible srvgroup -m debug -a "msg={{ | min }}"
ansible srvgroup -m debug -a "msg={{ | zip(['a','b','c','d','e']) | list }}"
ansible srvgroup -m debug -a "msg={{ | zip(['a','b','c','d','e']) | list | to_nice_yaml }}"
ansiblelocalhost -m debug -a "msg={{ 'redhat' | password_hash('sha512')}}"
