In Ansible, how to filter a dictionary based on regex pattern on the keys?
I need to extract a subset of a dictionary based on a pattern on the key names.
For example, in the v below I need to extract the key->values section1*.
The code below assigns the list of values, but I still haven't found a way to preserve the key->map setting.
- set_fact:
v:
section1_1: true
section1_2: false
section2_1: true
section2_2: false
section3: true
- set_fact:
v2: " select('match','^section1_.*') "
- debug:
var: v2
Any help, please?
Thanks.

fatal: [localhost]: FAILED! => "msg": "template error while templating string: no filter named 'items2dict'. String: selectattr('key', 'match', '^section1_') "
If I look at the sources in /usr/lib/python2.7/dist-packages I see that there are references to it, but not real function definitions
ansible/plugins/filter/core.py: raise AnsibleFilterError("items2dict requires a list, got %s instead." % type(mylist))
ansible/plugins/filter/core.py: 'items2dict': list_of_dict_key_value_elements_to_dict,
I'm runing 2.5.1. Do I need a later version?
