У меня есть следующий код в tasks / main.yml
---
- name: Check if service exists.
shell: "systemctl status {{ service }}"
ignore_errors: yes
register: service_exists
- name: Enable service and start if it exists.
systemd:
name: "{{ service }}"
state: started
enabled: true
when: "could not be found" not in service_exists.stderr' or '"Failed to get properties" not in service_exists.stderr' or '"not-found" not in service_exists.stderr'
У меня есть следующий код в configure-services.yml
---
- hosts: localhost
become: true
gather_facts: yes
tasks:
- include: tasks/main.yml
with_items: "{{ services }}"
loop_control:
loop_var: service
Однако я получаю приведенную ниже ошибку при запуске playbook.
fatal: [localhost]: FAILED! => {"reason": "Syntax Error while loading YAML.\n did not find expected key\n\nThe error appears to have been in '/home/adambirds/Development/ansible-playbooks/system-services/tasks/main.yml': line 12, column 11, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n enabled: true\n when:''\"could not be found\" not in service_exists.stderr' or '\"Failed to get properties\" not in service_exists.stderr' or '\"not-found\" not in service_exists.stderr''\n ^ here\nWe could be wrong, but this one looks like it might be an issue with\nunbalanced quotes. If starting a value with a quote, make sure the\nline ends with the same set of quotes. For instance this arbitrary\nexample:\n\n foo: \"bad\" \"wolf\"\n\nCould be written as:\n\n foo: '\"bad\" \"wolf\"'\n"}
Я полагаю, что проблема связана с моим оператором when: , моя цель - выполнить задачу, еслини один из приведенных ниже не появляется в service_exists.stderr :
could not be found
Failed to get properties
not-found
После использования предложения @tinita ниже и изменения tasks / main.yml к следующему:
---
- name: Check if service exists.
shell: "systemctl status {{ service }}"
ignore_errors: yes
register: service_exists
- name: Enable service and start if it exists.
systemd:
name: "{{ service }}"
state: started
enabled: true
when: >
"could not be found" not in service_exists.stderr
or "Failed to get properties" not in service_exists.stderr
or "not-found" not in service_exists.stderr
Я получаю следующие ошибки при запуске playbook:
