Ansible 剧本引用了一个 git 角色，它应该在本地主机上运行，但它没有

Question

I need to be able to use the ansible git module to git pull on ansible controller from the respective branch based on the target branch of commit / merge. 我将 ansible git 放在一个角色中，并在每个剧本中引用该角色作为第一件事。 这个 git 角色在localhost上运行。

我有以下库存：

PreProd:
  hosts:
    myhost.mydomain.com:

local:
  hosts:
    localhost:

和剧本：

- hosts: local
  connection: local
  vars_files:
    - "../group_vars/{{ ENV }}/{{ ENV }}.yml"

  tasks:
    - name: Print variables
      debug:
        msg: "{{ ENV }} {{ var_username }}:{{ var_password }} branch: {{ var_branch }}"

  roles:
  - git

- name: Deploy My Application
  hosts: "{{ ENV }}"
  gather_facts: false
  tasks:
    - debug:
        msg: "branch: {{ var_branch }}"

我在group_vars有以下结构：

group_vars\
   all\all.yml
   PreProd\PreProd.yml

我在group_vars的所有组中定义了var_branch变量，但在group_vars\all\all.yml中没有定义，因为这个变量是特定于环境的。

当我运行剧本时，它会尝试建立连接，即使它显示localhost ：

$  ansible-playbook -i preprod-servers.yml playbooks/test.yml -e ENV=PreProd

任何建议和见解都值得赞赏。

建议：

1. 永远不要在同一个清单中有多个环境（例如 PREPROD 和 LOCAL）。
2. Ansible 将自动将group_vars文件中的变量分配给这些组中的主机。 不要将vars_files与group_vars文件一起使用。
3. 对于local组，或者对于localhost ，设置connection: local
