ansible - 在ansible playbook中连接多个变量和字符串

Question

在为目标部分执行 with_items 时，我正在尝试多重串联。

现在看起来像这样:

- name: create app except+lookup
  copy: content="" dest="{{ dir.comp ~ '/config/con2dd/' ~ item.name ~ 'File.txt' }}" force=no group=devops owner=devops mode: 0755
  with_items:
...

我得到:

We could be wrong, but this one looks like it might be an issue with
missing quotes.  Always quote template expression brackets when they 
start a value. For instance:            

    with_items:
      - {{ foo }}

Should be written as:

    with_items:
      - "{{ foo }}"

尝试了几种方法，但没有一个有效。

是否可以将变量与字符串连接起来？

不要将纯 YAML 和 key=value 语法混合用于参数。并且始终对复杂参数使用 YAML 语法:

- name: create app except+lookup
  copy:
    content: ""
    dest: "{{ dir.comp }}/config/con2dd/{{ item.name }}File.txt"
    force: no
    group: devops
    owner: devops
    mode: 0755
  with_items:
  ...
