从ansible开始并行启动Cloudformation堆栈

Question

我正在＆＃34; with_items＆＃34;中启动多个cloudformation堆栈。像这样在ansible循环：

- name: Create CF stack in AWS
  cloudformation:
    stack_name: "{{ item.name }}"
    state: "present"
    template: "{{ item.name }}.py.json"
    template_parameters: "{{ item.template_parameters }}"
  with_items: "{{ CF_TEMPLATE_ITEMS }}"

我可以以某种方式让ansible并行启动这个堆栈吗？

Answer 1

在启用了fire-and-forget方案中使用异步任务（并等待它们在单独的任务中完成）应该起作用，因为ansible 2.0：

- name: Create CF stack in AWS
  async: 100
  poll: 0
  cloudformation:
    stack_name: "{{ item.name }}"
    state: "present"
    template: "{{ item.name }}.py.json"
    template_parameters: "{{ item.template_parameters }}"
  with_items: "{{ CF_TEMPLATE_ITEMS }}"
  register: cf_stack_async_results

- async_status:
    jid: "{{item.ansible_job_id}}"
  with_items: cf_stack_async_results.results
  register: cf_stack_async_poll_results
  until: cf_stack_async_poll_results.finished
  retries: 30
