with_dict expects a dict - when evaluating a variable in ansible 2.0+

Hi everyone,

I’m trying to get this example to work with ansible 2.0+. It does work correctly with 1.9.

`

  • hosts: localhost
    vars:

input: “top”

base: &base
? a
? b

top: &top
<< : *base
? c
? d

peak: &peak
<< : *top
? e
? f

tasks:

  • debug: var=“{{ input|lower|regex_replace(’ ‘,’') }}”

  • name: Loop
    command: echo {{ item.key }}
    with_dict: “{{ input|lower|regex_replace(’ ‘,’') }}”
    `

In short, I want to merge the dicts base, top and peak and then loop over all key/value pairs in the corresponding dictionary, depending on the input another function produces (strings).

With ansible 2.0 I get the following error:

`

In ansible 1.9 I get my desired result:

`

`

Do you have any idea how I can get this to work?

Thank you very much,

The solution is to address the variable like this (vars[‘variableName’]):

`

  • name: Loop
    command: echo {{ item.key }}
    with_dict: “{{ vars[input|lower|regex_replace(’ ‘,’')] }}”

`
