Ansible: creating variables from json string
In Ansible, is there a way to convert a dynamic list of key / value pairs that are in a JSON variable to variable names / values that can be accessed in the Playbook without using the file system?
IE. If I have the following JSON in a variable (in my case already imported from a URI call):
{
"ansible_facts": {
"list_of_passwords": {
"ansible_password": "abc123",
"ansible_user": "user123",
"blue_server_password": "def456",
"blue_server_user": "user456"
}
}
Is there a way to convert this JSON variable to equivelant from:
vars:
ansible_password: abc123
ansible_user: user123
blue_server_password: def456
blue_server_user: user456
I usually have to write the variable to a file and then import it using vars_files:
. Our goal is not to write secrets to the file system.

You can use the uri module to make the call and then register the response to the variable:
For example:
- uri:
url: http://www.mocky.io/v2/59667604110000040ec8f5c6
body_format: json
register: response
- debug:
msg: "{{response.json}}"
- set_fact: {"{{ item.key }}":"{{ item.val }}"}
with_dict: "{{response.json.ansible_facts.list_of_passwords}}"
