在ansible playbook中Concat多个变量和字符串

Question

在with_items为目标部分执行预处理时,我正在尝试多个连接.

现在它看起来像这样:

- 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:
...

我明白了:

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,但没有一种方法可以实现.

是否可以用字符串连接变量？

不要为参数混合纯YAML和key = value语法.并且始终将YAML语法用于复杂参数:

- 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:
  ...
