Automation 使用Ansible创建任意数量的DigitalOcean水滴

当我调用ansible的剧本时，我想创建任意数量的水滴。 例如： 我需要创建10个运行python代码的水滴

$ ansible-playbook install_pyapp_commission_new.yml --extra-vars "number_of_droplets_to_create=10"

我尝试将

与_sequence:count=X一起使用，但无法将其应用于角色或内部任务（据我所知）。我的剧本是这样的：

- name: Digital Ocean Provisioning
  hosts: 127.0.0.1
  gather_facts: false
  connection: local
  roles:
    - { role: do_provision, do_droplet_number: "{{ number_of_droplets_to_create | default(01) }}" }

- name: Setting up application
  gather_facts: true
  user: root
  hosts: do_instances
  roles:
    - { role: application, wait_time: 60 }

- name: Digital Ocean Provisioning
  hosts: 127.0.0.1
  gather_facts: false
  connection: local
  roles:
    - { role: do_provision, do_droplet_number: "{{ item }}" }
  with_sequence: count={{ number_of_droplets_to_create }}

因此，我将输入的液滴数量传递给
do_provision
作为
do_droplet_number
，因为我每次运行都创建一个（这样我可以从bash并行运行10个，每个都有不同的数量，从而实现我的目标，但这是一个肮脏的解决方案）

我想做这样的事情：

- name: Digital Ocean Provisioning
  hosts: 127.0.0.1
  gather_facts: false
  connection: local
  roles:
    - { role: do_provision, do_droplet_number: "{{ number_of_droplets_to_create | default(01) }}" }

- name: Setting up application
  gather_facts: true
  user: root
  hosts: do_instances
  roles:
    - { role: application, wait_time: 60 }

- name: Digital Ocean Provisioning
  hosts: 127.0.0.1
  gather_facts: false
  connection: local
  roles:
    - { role: do_provision, do_droplet_number: "{{ item }}" }
  with_sequence: count={{ number_of_droplets_to_create }}

但这是无效的。
这应该使用循环而不是\u序列

它将循环转换为角色，因为剧本中不能包含“何时”。
当do_droplet_编号为0时，需要“when”来防止创建液滴

  vars:

  roles:
    - { role: do-provision, do_droplet_number: "{{ thiscount }}" }

- name: display number
  debug:
    msg: "mycount {{ item }}"
  loop: "{{ range(0, do_droplet_number|int) |list }}"
  when: thiscount > 0
