Yep, realized I was trying to parse it as JSON, or YAML very much
incorrectly...
I have a solution now, though it's quite ugly and requires replacing a
character and splitting on newlines....
- name: Get userdata
uri:
url: http://169.254.169.254/latest/user-data
return_content: yes
register: rawdata
- name: Replace hyphen with undserscore since hyphens are not valid in
python variables
set_fact:
metadata: "{{ rawdata | replace('-','_') }}"
- name: Set userdata fact
set_fact:
userdata: "{{ metadata.content.split('\n') }}"
- set_fact:
"{{ item.split('=')[0] }}": "{{ item.split('=')[1] }}"
with_items: "{{ userdata }}"
