Ansible 模組查找新主機名和更新配置文件

你能幫忙解決這個問題嗎？我正在嘗試將主機名寫入文件。

---
- name: Update host.
 hosts: all
 connection: local
   # Default Value
   domain: '{{ default_domain }}'
   hostname: “serv1.{{ '{{' }} domain {{ '}}' }}"
 tasks:
   - name: Update hostname config file
     block:
       - lineinfile:
           path: /home/test/conf.yml
           state: present
           regexp: 'authorization-uri:(.*)$'
           line: "authorization-uri: https://{{ serv1.{{ '{{' }} domain {{ '}}' }}/key/auth/mvn/vars/lenz/svc/chk”

Domain = serv1
Hostname = app2
Output should be:
https://serv1.app/key/auth/mvn/vars/lenz/svc/chk”

給定遠端主機和文件

$ hostname -f
test_01.example.org

$ cat /tmp/config.yml
# authorization-uri
uri: server.old_hostname/ask/params/class

劇本完成任務

- hosts: test_01
 tasks:
   - command: hostname -f
     register: result
   - lineinfile:
       dest: /tmp/config.yml
       insertafter: '^# authorization-uri(.*)$'
       regexp: '^uri: server\.(.*)/ask/params/class$'
       line: "uri: server.{{ result.stdout }}/ask/params/class"

給

$ cat /tmp/config.yml
# authorization-uri
uri: server.test_01.example.org/ask/params/class

---

正則表達式的解釋

'^uri: server\.(.*)/ask/params/class$'

^ ................. the beginning of the line
uri: server\. ..... text; the dot must be escaped
(.*) .............. any sequence
/ask/params/class   text
$ ................. end of the line
