如何通过 ansible 从 ansible 变量中删除前导零?

来自How to remove leading zeros from a variable? 我想运行以下功能,但无法运行。

$ a=01234
$ b=00001234
$ c=1234
$
$ echo "${a#${a%%[1-9]*}}"
1234
$ echo "${b#${b%%[1-9]*}}"
1234
$ echo "${c#${c%%[1-9]*}}"
1234

我的尝试是:

- shell: "echo ${% raw -%}{{% endraw -%}{{mpp_number_with_leading_zeros}}#${% raw -%}{{% endraw -%}{{mpp_number_with_leading_zeros}}%%[1-9]*{% raw -%}}{% endraw -%}{% raw -%}}{% endraw -%}"

我使用的是 ansible 2.9

您可以使用 int 插件转换变量,如下所示:

  vars:
    var1: "01234"
    var2: "00001234"
    var3: "1234"

  tasks:
  - debug:
      msg: "{{ item }}"
    with_items:
      - "{{ var1 }}"
      - "{{ var2 }}"
      - "{{ var3 }}"
      - "{{ var1 | int }}"
      - "{{ var2 | int }}"
      - "{{ var3 | int }}"
