How to use ExtractValue in Ansible Playbook?

[lug-gh]

Question

Hello, I have created an “integration” in the semaphore, which is configured as follows:

ExtractValue

• values source: body
• body data type: json
• key: vmname
• environment variable: vmname

matcher

• type: body
• method: equals
• body data type: json
• key: key
• value: test

This triggers my ansible task “webhook test”.

If I trigger the webhook with the following command:
curl -i -H "Accept: application/json" -H "Content-Type:application/json" -X POST --data "{\"key\": \"test\", \"vmname\": \"test\"}" https://semaphore.example.org/api/integrations/1234567890abcdef
then the ansible task starts, but the environment variable “vmname” is empty.

- name: webhook test
  hosts: localhost
  tasks:
    - name: debug
      debug:
        msg: "VM NAME: {{ lookup('env', 'vmname') }}"

only prints VM NAME:

Even if I display the entire env, I can't find my variable anywhere, only the env variables of the task itself.

- name: show all env
  hosts: localhost
  gather_facts: yes
  tasks:
    - name: show all env
      debug:
        var: ansible_facts.env

I use semaphore in docker, and have the following in my docker compose env:
SEMAPHORE_FORWARDED_ENV_VARS: '["vmname"]'
Unfortunately, this did not help either, the variable is still empty or not set.

Okay, I was thinking too complicated. The variable is not loaded as an environment variable, but directly as an ansible variable.

So simply {{ vmname }}, instead of {{ lookup('env', 'vmname') }}
