ansible - 检查异步 Ansible 任务的标准输出

Question

如何基于异步 Ansible 任务的 stdout 来failed_when？我尝试过以下变体:

- name: Run command
  command: arbitrary_command
  async: 3600
  poll: 10
  register: result
  failed_when: "Finished 'command'" in result.stdout

这会导致:

fatal: [localhost] => error while evaluating conditional: "Finished 'command'" in result.stdout

Answer 1

任务完成后，使用async_status获取异步任务的状态:

- name: Run command
  command: arbitrary_command
  async: 3600
  poll: 10
  register: result_async

- name: Check command
  async_status: jid="{{ result_async.ansible_job_id }}"
  register: result
  failed_when: result.finished != 1 or "Finished 'command'" not in result.stdout
