Ansible Playbook：错误！ “ delegate_to”不是Play的有效属性

Question

我制作了一部剧本，然后通过主机复制了我的版本包，但是我的主剧本中的“ delegate_to”存在一些问题。我已经尝试了一切。看到错误了吗？

剧本

- name: Install GEOPos2 Ansible on Central
  hosts: central_servers
  roles:
    - central_servers

- name: Copy version package from central_servers to local_servers
  hosts: local_servers
  synchronize: src=/devops/geopos2-alkosto-{{ version }}-Package.zip dest=/devops/
  delegate_to: central_servers[0]

- name: Install GEOPos2 Ansible on Local
  hosts: local_servers
  roles:
    - local_servers

- name: Copy version package from local_servers to pos
  hosts: pos
  synchronize: src=/devops/geopos2-alkosto-{{ version }}-Package.zip dest=/devops/
  delegate_to: local_servers[0]

- name: Install GEOPos2 Ansible on POS
  hosts: pos
  roles:
    - pos

- name: Deleting packages from local and central servers
  hosts: central_servers:local_servers
  file:
    state: absent
    path: /devops/geopos2-alkosto-{{ version }}-Package.zip

输出：

ERROR! 'delegate_to' is not a valid attribute for a Play

The error appears to have been in '/workspace/devops/alkosto/install-alkosto/repo/playbook.yml': line 8, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:


- name: Copy version package from central_servers to local_servers
