我正在尝试在 Concourse 中为远程主机运行 ansible playbook，但是我不能这样做。以下是我的步骤：-

大厅 Yaml 文件：-

---
resource_types:
- name: ansible-playbook
  type: docker-image
  source:
    repository: troykinsella/concourse-ansible-playbook-resource
    tag: latest

resources:
- name: ansible
  type: ansible-playbook
  source:
    debug: true
    user: cloud_user
    ssh_private_key: ((ssh-key))
    verbose: vvv

- name: source-code
  type: git
  source:
    uri: ((git-repo))
    branch: master
    private_key: ((ssh-key))

jobs:
  - name: ansible-concourse
    plan:
    - get: source-code # git resource
    - put: ansible
      params:
        check: true
        diff: true
        become: true
        become_user: root
        inventory: inventory/hosts
        playbook: site.yml
        path: source-code

主机文件：-

[test]
localhost

容器内：-

我拦截了容器，我可以 ssh 到里面的任何 IP，但是我无法进行 ssh 登录。

Ansible 剧本：-

---
- name: "Running Current Working Directory"
  hosts: test
  gather_facts: no

  tasks:
     - name: "Current Working Directory"
       shell: pwd
       register: value

     - debug:
          msg: "The Current Working Directory {{value.stdout_lines}}"

输出在大厅：-

localhost通常通过local连接插件访问（除非您尝试做一些非常特别的事情并且您已经通过 ssh 配置了访问权限，而上述错误消息似乎并非如此）。

如果您未在清单中声明它，则它localhost是隐式的，使用连接并且在组local中不匹配。all

但是，如果您localhost在清单中明确声明，则默认连接插件将变为ssh并且该all组也与此主机匹配。在这种情况下，您必须将连接设置回您local自己。

您有两个选项可以使您当前的测试工作：

  1. 删除您的库存（或使用未明确声明的库存localhost）并修改您的剧本以localhost直接定位 =>hosts: localhost
  2. 保持你的剧本原样并修改你的库存 
    [test]
localhost ansible_connection=local
