Question

我需要从需要包含列表的配置文件中读取。该列表需要作为参数传递给角色。

<body <?php body_class(); ?>>

conf1 / TMP.txt文件的内容如下：

---
- name: run command on localhost
  hosts: localhost
  tasks:
    - name: read variables from file
    shell: cat {{ conf1/TMP.txt }}
    register: contents
- name: role to trigger the run script process
  hosts: otherhost
  roles:
    - { role: run_script, applist: "{{ contents }}"  }

上述代码段无效，但以下代码段有效：

[ 'a', 'b', 'c', 'd' ]

Answer 1

尝试使用查找过滤器而不是shell命令。以下示例..

---
- name: run command on localhost
  hosts: localhost

  tasks:
    - set_fact:
        contents: "{{ lookup('file', 'tmp.txt')  }}"
    - debug: var=contents

- name: role to trigger the run script process
  hosts: localhost
  roles:
    - { role: foo, applist: "{{ contents  }}" }

debug的输出应该如下所示

ok: [localhost] => {
"foo": [
    "1",
    "2",
    "3",
    "4"
]}

将列表传递给Ansible中的角色
