Ansible Playbook 将数组列表作为变量传递

Question

so we currently have a create directories yml and it has 20 or so folders it creates.. I'm attempting to streamline that and pass in the folders with the mode and recurse flag which are all different. As a test I created this.

- debug: msg="testing = {{ testing }}"
- name: "loop through list from a variable"
  debug:
    msg: "dest: {{ item.dest }}, mode: {{ item.mode }}, recurse: {{ item.recurse }}"
  with_items: "{{ testing }}"

Normally we have something like this:

- name: Create Multiple Directories
  file:
    path: "{{ item.dest }}"
    mode: "{{ item.mode }}"
    recurse: "{{ item.recurse }}"
    state: directory
  with_items:
    - { dest: '/local/path1', mode: '0775', recurse: yes }
    - { dest: '/local/path2', mode: '0777', recurse: no }

So my problem is we use AaaS to pass information over and how the parameter is set.. We have a TextBox on a web page. I tried the following with no luck.

- { dest: '/local/path1', mode: '0775', recurse: yes }
- { dest: '/local/path2', mode: '0777', recurse: no }

and

{ dest: '/local/path1', mode: '0775', recurse: yes }
{ dest: '/local/path2', mode: '0777', recurse: no }

and

dest: '/local/path1', mode: '0775', recurse: yes
dest: '/local/path2', mode: '0777', recurse: no

The error I'm getting in all cases states 'dest' does not exist. Is it formatting or is there something else I need to consider?

Answer 1

I don't have rep to make a comment, but i would think that the yaml you're sending in the first example is a list, but sending yaml via HTTP to an AaaS is difficult. You might try sending a JSON blob, so you can send:

[{"dest": "/local/path1", "mode": "0775", "recurse": true },
{"dest": "/local/path2", "mode": "0777", "recurse": false }]

And that would probably make your life easier

EDIT: removed the single quotes as it's likely that a Text Box would be interpreted as a string already

Answer 2

Q: "Is it formatting or is there something else I need to consider?"

A: The code works for me. (I've only changed the destinations eg dest: '/usr/local/test/path1' ). See below the dir before and after.

shell> tree /usr/local/test
/usr/local/test

0 directories, 0 files

shell> tree /usr/local/test
/usr/local/test
├── path1
└── path2

2 directories, 0 files

shell> ll /usr/local/test
total 16
drwxr-xr-x  4 root root 4096 Jun  1 21:00 ./
drwxr-xr-x 12 root root 4096 Jun  1 21:00 ../
drwxrwxr-x  2 root root 4096 Jun  1 21:00 path1/
drwxrwxrwx  2 root root 4096 Jun  1 21:00 path2/
