how to get value from yaml file ?

[Eric Chang]

I want to run a playbook to create an individual folder for users in different groups

and I already create a teams.yml file like below

        {

            "chinese_name": "\u8ca1\u52d9\u6703\u8a08\u8655",

            "description": "\u8ca1\u52d9\u6703\u8a08\u8655",

            "gid": 10126,

            "location": [

                "hq"

            ],

            "name": "ac",

            "users": [

                "tsengyi",

                "chenp",

                "lich",

                "hsiaoch",

                "wangr",

                "dengm",

                ""guot". 

            ]

then I wrote a task

 ### load yaml file first

- name: load teams.yml                                                                                                                                          

  tags:

    - env

  include_vars:

    file: files/konwen/teams.yml

- name: create folders

  file:

    path: "/home/{{item.user}}/D"

    state: present

  when:  item.name ==  'ac'

  with_items: "{{ teams}}"

 

 but the result 

 tsengyi

'[u'\''tsengyi'\'', u'\''chenp'\'', u'\''lich'\'', u'\''hsiaoch'\'', u'\''wangr'\'', u'\''dengm'\'', u'\''guot'\'', u'\''hsul'\'', u'\''linm'\'']'

 wangc

looks like ansible take whole list  into a single value

I expect to create /home/tsengyi/D , /home/chenp/D .....and so on

How can I separate the list into piece to do what I need ??

Hi,

your file looks like JSON to me, not like YAML (though one is a subset of the other, if I remember correctly…).

My test:

### teams.yaml ###
---

chinese_name: "\u8ca1\u52d9\u6703\u8a08\u8655"

description: "\u8ca1\u52d9\u6703\u8a08\u8655"

gid": 10126
location":
- "hq"
name: "ac"
users:
- tsengyi
- chenp
- lich
- hsiaoch
- wangr
- dengm
- guot
##################

### test.yaml ###
---
- hosts: localhost
gather_facts: false
tasks:
- include_vars: teams.yaml
- debug:
msg: '{{ item }}'
loop: '{{ users }}'
#################

results in:

$ ansible-playbook test.yaml

PLAY [localhost] ***************************************************************

TASK [include_vars] ************************************************************
ok: [localhost]

TASK [debug] *******************************************************************
ok: [localhost] => (item=tsengyi) =>

ok: [localhost] => (item=chenp) =>
msg: chenp
ok: [localhost] => (item=lich) =>

ok: [localhost] => (item=hsiaoch) =>
msg: hsiaoch
ok: [localhost] => (item=wangr) =>
msg: wangr
ok: [localhost] => (item=dengm) =>

ok: [localhost] => (item=guot) =>
msg: guot

PLAY RECAP *********************************************************************

I you want the content of teams.yaml to be inside variable "teams" you need to tell that Ansible:

tasks:
- include_vars:
file: teams.yaml
name: teams

That way, you can refer to teams["users"] and not just to users as in my test.yaml.

thanks for reply , I think my source file is yaml file

I can pass the yaml validator online

here are 2 items in teams.yml

"teams": [
    {"chinese_name": "\u79d8\u66f8\u90e8","description": "\u79d8\u66f8\u90e8","gid": 10125,"location": ["hq"],"name": "aa","users": ["chenhu","chouf"]},
    {"chinese_name": "\u8ca1\u52d9\u6703\u8a08\u8655","description": "\u8ca1\u52d9\u6703\u8a08\u8655","gid": 10126,"location": ["hq"],"name": "ac","users": ["chenchiao","chengc"]}
    ]

even I assign a name in task , I still can not use users with tasks below

- name: load teams.yml                                                                                                                
  tags:
    - env
  include_vars:

    file: files/teams.yml
    name: teams

- name: debug
  tags:
    - env

  debug:
    msg: "{{ item }}"
  loop: " {{ users }}"

I can print the {{ teams }} , but can not get valule from {{ team.users }} or {{ team.name }}

FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'name' is undefined / The error was: 'chinese_name' is undefined

What version of Ansible?

Are you sure the files are encoded in UTF-8?
