Hi everyone,

I have a variable where i want to loop on this in a .yml task file :

My variable :  
`  
lst\_apps:

- {name: APP01, version: 1234, bdd\_sid: BDDSID, bdd\_host: SERVEURBDD, bdd\_port: 1525}

`

Content of my main.xml :  
`

- name: Test display variable  
debug:  
msg: “{{ lst\_apps }}”  
tags: test

- name: Installation des differentes applications  
include: 2-install.yml  
with\_items:

- “{{ lst\_apps }}”  
loop\_control:  
loop\_var: tmp\_deploy\_app  
tags: install,test  
`

Content of my yml task file where the loop is executed :  
`

- name: Test display variable in task file  
debug:  
msg: “{{ item.bdd\_sid }}”  
with\_items: “{{ tmp\_deploy\_app }}”  
`

When i execute the task, the content of variable is correctly display but the loop in the task file does not work :

`

tmp\_deploy\_app doesn't contain a list, it is a dict.  
You can check that with putting this first in your 2-install.yml file

- debug: var=tmp\_deploy\_app

So if you are going to loop you need to use with\_dict.  
But for you example above you only need this

- name: Test display variable in task file  
&nbsp;&nbsp;&nbsp;debug:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;msg: "{{ tmp\_deploy\_app.bdd\_sid }}"

Hi,

Thanks for your reply,

I have this in my main.yml :  
`

- name: Installation des differentes applications  
include: 2-install.yml  
with\_items:
- “{{ mcs\_lst\_apps }}”  
loop\_control:  
loop\_var: tmp\_deploy\_app  
tags: install,test  
`

And this in my 2-install.yml

`

- debug: var=tmp\_deploy\_app  
`

But when i execute it, it’s the same thing :  
`TASK [MCS_ROLE : Installation des differentes applications] ******************************************************************************************** included: /projet/roles/MCS_ROLE/tasks/2-install.yml for SERVER`
