Ansible은 정규식 문제를 예상합니다.

Ansible은 정규식 문제를 예상합니다.

저는 Ansible의 초보자입니다. 패키지 설치를 자동화하기 위해 Ansible과 함께 Expect를 사용하려고 했습니다(아래 예에서는 제거). Lynx 패키지를 수동으로 제거하는 동안 다음 메시지가 나타납니다. 예상 응답 필드에서 이 패턴(두 줄 모두)을 일치시키려고 했지만 스크립트가 실패했습니다. 한 줄에서는 작동하지만 괜찮나요? [y/N]: y. 두 줄 모두에 사용한 정규 표현식은 Installed size: 5.4 M\n괜찮나요 [y/N]: y

-----------------------
Installed size: 5.4 M
Is this ok [y/N]: 
----------------------

코드 1(두 줄의 패턴 일치 - 실패):

[ansible@localhost ansible]$ cat main.yml
---
- hosts: localhost 
  remote_user: ansible
  become: yes
  become_method: sudo
  connection: ssh
  gather_facts: yes
  tasks:
  - name: remove a package 
    expect:
      command: yum remove lynx
      responses:
        Installed size: 5.4 M\nIs this ok \[y\/N\]: y 
        #Is this ok \[y\/N\]: y
      echo: yes

산출:

[ansible@localhost ansible]$ ansible-playbook main.yml
[DEPRECATION WARNING]: DEFAULT_SUDO_USER option, In favor of become which is a generic framework . This feature will be removed in version 2.8. Deprecation 
warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.
ERROR! Syntax Error while loading YAML.


The error appears to have been in '/etc/ansible/main.yml': line 13, column 51, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

      responses:
        Installed size: 5.4 M\nIs this ok \[y\/N\]: y
                                                  ^ here

exception type: <class 'yaml.scanner.ScannerError'>

================================================= ====================== 코드 2(한 줄에 대한 패턴 일치 - 잘 작동함):

[ansible@localhost ansible]$ cat main.yml

- hosts: localhost 
  remote_user: ansible
  become: yes
  become_method: sudo
  connection: ssh
  gather_facts: yes
  tasks:

      responses:
        #Installed size: 5.4 M\nIs this ok \[y\/N\]: y

답변1

다음을 사용하는 것이 더 나을 것입니다.냠 모듈.

---
- hosts: localhost 
  remote_user: ansible
  become: yes
  become_method: sudo
  connection: ssh
  gather_facts: yes
  tasks:
  - yum: 
      name: lynx
      state: absent

또는패키지

---
- hosts: localhost 
  remote_user: ansible
  become: yes
  become_method: sudo
  connection: ssh
  gather_facts: yes
  tasks:
  - pacakge: 
      name: lynx
      state: absent

가능하면 항상 명령/셸 대신 모듈을 사용해야 합니다. 모듈은 쉘/명령에 수많은 논리를 추가하지 않고도 오류 검사 및 멱등성을 제공합니다.

답변2

제안해 주셔서 감사합니다. 예, YUM을 사용하겠습니다. 어쨌든 아래 정규 표현식으로 내 문제가 해결되었습니다.

Installed.*\nIs this ok \[y\/N\]: y


Code:
---
- hosts: localhost 
  remote_user: ansible
  become: yes
  become_method: sudo
  connection: ssh
  gather_facts: yes
  tasks:
  - name: remove a package 
    expect:
      command: yum remove lynx
      responses:
        Installed.*\nIs this ok \[y\/N\]: y 
        # Is this ok \[y\/N\]: y
      echo: yes
