include lines from a text file inside a .j2 file

[Dalton Porter]

I have a list of items in a text file that need to go into a specific location in the output file.

The text file is one item per line:

user1

user2

...

The output file looks like

Section1:

Section2:

user=user1, task=shuffle

user=user2, task=shuffle

...

Section3:

----------------

I'm using ansible templates to do this.

- name: configure users

  template: src=roles/sys/templates/users.j2 dest=/opt/users.dat backup=yes

I need the users to go in section 2.  I've tried things like this but I can't find what works yet.

In the j2 file:

Section1: 

Section2:

{% for name in item %}

user= {{name}} , task=shuffle

{% endfor %}

Section3:

How should I read in the users from the file?  Store the file data in what?

How do I then feed that to the template so that the for loop works?

You want to use a lookup:



vars:
users: "{{ lookup('file', '/home/dalton/users.txt') }}"

tasks:
- name: Template out
template:
src: roles/sys/templates/users.j2
dest: /opt/users.dat
backup: yes

Your template would then look like:

Section1:
Section2:
{% for name in users.splitlines() %}

user= {{ name }}, task=shuffle
{% endfor %}
Section3:
