Hi,
I tried to construct an array with set_fact and I found
this:
http://stackoverflow.com/questions/23507589/is-it-possible-to-set-a-fact-of-an-array-in-ansible
So I tested:
tasks:
- set_fact: foo="[ 'one', 'two', 'three' ]"
- debug: var=foo
- set_fact: foo="{{foo}} + [ 'four' ]"
- debug: var=foo
and it worked very well.
But when I try to add a 'with_items':
tasks:
- set_fact: foo="[ 'one' ]"
- debug: var=foo
- set_fact: foo="{{foo}} + [ '{{item}}' ]"
with_items: [ "two", "three" ]
- debug: var=foo
It doesn't work, I get:
"foo": [
"one",
"three"
]
instead of:
"foo": [
"one",
"two",
"three"
]
Whereas this works:
tasks:
- name: set foo fact to an array
set_fact: foo="[ 'one' ]"
- debug: var=foo
- set_fact: foo="{{foo}} + [ 'two' ]"
- set_fact: foo="{{foo}} + [ 'three' ]"
- debug: var=foo
But is not suitable for my needs (It just proves that a fact can be
overriden multiple times).
The behaviour of with_items is not what I expected, is something wrong with
my approach?
I'm using ansible 1.8.2 on ubuntu 14.04
Regards,
Michaël
