Hello all,
I am currently looking at a quote issue in an ansible nested variable and i
cannot get it clear why it is not working. Can you help me out?
Some details:
hostname:
x55-n12
I want to get the first value (x55) with a regular expression:
(.*?)(?=\-)
and place this value in a file called rack.
Ansible task file:
---
- include_vars: default.yml
- name: 'Place files'
template: >
src={{ item.src }}
dest={{ item.dest }}
owner=root group=root mode=0644
with_items:
- { src: klaas/attributes/rack.j2 , dest: "/klaas/attributes/rack"}
register: klaasconfig
- name: Remove latest file and restart
file: directory=/tmp/klaas/meta/slaves/latest/ state=absent
when: klaasconfig.changed
notify: restart klompendans
***
rack.j2 file:
{{ rack }}
***
default.yml file:
---
firewalld_zone: kees
rack: "{{ ansible_hostname | regexp_replace(.*?)(?=\-) }}"
****
Now the error:
Note: The error may actually appear before this position: line 8, column 52
firewalld_zone: kees
rack: "{{ ansible_hostname | regexp_replace(.*?)(?=\-) }}"
^
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 }}"
***
According to my git commits I have changed the regex to (and a couple more,
but it shows i do not know how to handle this regex):
rack: {{ ansible_hostname | regexp_replace(.*?)(?=\-) }}
rack: {{ ansible_hostname | regexp_replace"(.*?)(?=\-)" }}
rack: "{{ ansible_hostname | regexp_replace('(.*?)(?=\-)') }}"
rack: {{ ansible_hostname | regexp_replace('(.*?)(?=\-)') }}
rack: "{{ ansible_hostname | regexp_replace((.*?)(?=\-)) }}"
The regex 'should' work because i have tried it a couple of times with sed
and python/javascript
Thanks so much for helping!
