在ansible中添加列表的每个元素
Prepend every element of a list in ansible
我希望在用户列表前加上 netbios 域名和反斜杠。到目前为止,这是我能想到的最好的:
- hosts: servers
vars:
mylist:
- Alice
- Bob
- Carol
mystring: test
mylist2: "{{ mylist | map('regex_replace', '^', mystring + '\' ) | list }}"
tasks:
- debug: var=mylist2
错误信息如下:
The offending line appears to be:
mystring: test
mylist2: "{{ mylist | map('regex_replace', '^', mystring + '\' ) | list }}"
^ here
We could be wrong, but this one looks like it might be an issue with
missing quotes. Always quote template expression brackets when they
start a value. For instance:
with_items:
- {{ foo }}
Should be written as:
with_items:
- "{{ foo }}"
我在将反斜杠连接到我的变量时遇到问题,因为 ansible 认为我正在尝试转义某些内容,但没有放入我想要转义的内容。我也尝试过使用双反斜杠无济于事。
有人可以建议在这里可行的方法或替代方法吗?
简化表达式,将regex_replace参数放入变量中,例如
- hosts: localhost
vars:
mylist:
- Alice
- Bob
- Carol
mystring: test
mylist2: "{{ mylist|map('regex_replace', _my_regex, _my_replace)|list }}"
_my_regex: '^(.*)$'
_my_replace: '{{ mystring ~ "\" ~ "" }}'
tasks:
- debug:
var: mylist2
大概给你想要的
mylist2:
- test\Alice
- test\Bob
- test\Carol
