How can I send Ansible Tower workflow template approval to Slack channel and recieve response from Slack channel?

Question

I have a situation where the approval logic in Ansible Tower workflow template is working fine, Slack notifications are also working fine, but, I want to send approve and deny buttons to Slack and capture response from Slack channel to Ansible Tower workflow template.

I get the notifications like this:

The approval node "Proceed for L1" needs review. This node can be viewed at: https://ansibletower/#/workflows/668
The approval node "Proceed for L1" was approved. https://ansibletower/#/workflows/668

The approval node "Proceed for L1" needs review. This node can be viewed at: https://ansibletower/#/workflows/674
The approval node "Proceed for L1" was denied. https://ansibletower/#/workflows/674

But can we get the approval messages like this:

I tried a playbook to use Slack module but waiting for the response and receiving action response was the challenge

    - name: Post Message to Slack
      slack:
        token: "{{ slack_token }}"
        attachments:
          - title: Launched {{ tower_job_id }} and Restart Service
            text: "*Actions:*"
            actions:
            - type: button
              text: Approve
              style: primary
              url: https://anisbletower/#/templates/job_template/17
            - type: button
              text: Deny
              style: danger
              url: https://ansibletower/#/templates/job_template/15
            - type: button
              text: Check Job Log
              url: https://ansibletower/#/jobs/playbook/{{ tower_job_id }}
        channel: {{ slack_channel }}
        domain: "app.slack.com"
      delegate_to: localhost

How can we capture the response (approved or denied) from Slack and send it to the job on Ansible Tower which is waiting?

Answer 1

Maybe after your task you can add a task that get the workflow status and move on only if the status is approved or denied, something like :

- name: get workflow status
  <some magic to get workflow_status, maybe uri module + tower api>
  until: workflow_status == approved or workflow_status == denied
  retries: 10
  delay: 10
