Ansible has difficulty restarting Supervisor

  • 772

I'm trying to restart Supervisor through my Ansible Playbook but I seem to be stumbling into an issue with the supervisor module for Ansible.

In my Supervisor config I have defined a program:

[program:process]
process_name=%(program_name)s_%(process_num)02d
command=/home/box1/workers/bin/process
numprocs=64
directory=/home/box1/workers/bin
autostart=true
autorestart=true
startretries=5
stderr_logfile=/tmp/%(program_name)s-err.log
stdout_logfile=/tmp/%(program_name)s-out.log
user=root

And this works fine. However, when I try to restart Supervisor through Ansible I get the following error:

failed: [box1] => {"failed": true}
msg: program:process: ERROR (no such process)
program:process: ERROR (no such process)

My Ansible task configuration looks like this:

- name: Restart Supervisor
  sudo: yes
  supervisorctl: name=program:process state=restarted config=/etc/supervisor/supervisord.conf

For the name parameter I have tried program:process, program, program: and process but none seem to work. I'm currently on Ansible 1.5.4.

  1. The supervisorctl Ansible module does not support the reload command (see here), which is needed for supervisor to pick up new configuration entries.

    You can do it yourself like this:

    - command: supervisorctl reread
  sudo: yes
- supervisorctl: name=program:process state=restarted config=/etc/supervisor/supervisord.conf
  sudo: yes

    The documentation on reload/reread/update/restart seems to be missing, and this blog post is out of date; you can experiment to make sure reload does what you expect.

    Finally, don't put your program definitions in supervisord.conf. Instead, put them as individual files in /etc/supervisor/conf.d/*.conf. That makes installation and maintenance much easier.
