Does ansible pass Role Default variables to the Handlers within the same Role?
Here's a minimal excerpt of the playbook that has the issue:
Role hierarchy
- playbook.yml
- roles/
- gunicorn/
- defaults/
- main.yml
- handlers/
- main.yml
- code-checkout/
- tasks/
- main.yml
Here's the file contents
gunicorn/defaults/main.yml
---
gu_log: "/tmp/gunicorn.log"
gunicorn/handlers/main.yml
---
- name: Clear Gunicorn Log
shell: rm {{ gu_log }}
finalize/tasks/main.yml
---
- name: Test Handlers
shell: ls
notify:
- Restart Gunicorn
playbook.yml
---
- name: Deploy
hosts: webservers
tasks:
- include: roles/finalize/tasks/main.yml
handlers:
- include: roles/gunicorn/handlers/main.yml
AFAIK everything looks good. However, I get this error during the playbook execution
FAILED! => {"failed": true, "msg": "the field 'args' has an invalid value, which appears to include a variable that is undefined. The error was: 'gu_log' is undefined\n\nThe error appears to have been in '/roles/gunicorn/handlers/main.yml': line 3, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: Restart Gunicorn\n ^ here\n"}
Using Ansible 2.2 on Ubuntu 12.04 LTS
Here's a modified version of techraf's script that creates all the directories and demonstrates my issue
#!/bin/bash
mkdir -p ./rtindru-test/roles/gunicorn
mkdir -p ./rtindru-test/roles/gunicorn/defaults
mkdir -p ./rtindru-test/roles/gunicorn/handlers
mkdir -p ./rtindru-test/roles/finalize/tasks
cat >./rtindru-test/roles/finalize/tasks/main.yml <<HANDLERS_END

- name: Test Handlers
shell: rm {{ gu_log }}
