supervisor Cookbook

Build Status

Installs (Python) supervisor and provides resources to configure services

Requirements

Platforms

Supports Debian and RHEL based systems. Tested on Ubuntu 12.04, 10.04, CentOS 6.5.

Cookbooks

  • python

Attributes

  • node['supervisor']['inet_port'] - The port on which you want to serve the internal web-based admin dashboard, e.g. 'localhost:9001'

  • node['supervisor']['inet_username'] - The username for authentication to this HTTP server

  • node['supervisor']['inet_password'] - The password for authentication to this HTTP server (supports both cleartext and SHA-1 hashed passwords prefixed by {SHA})

  • node['supervisor']['dir'] - location of supervisor config files

  • node['supervisor']['log_dir'] - location of supervisor logs

  • node['supervisor']['logfile_maxbytes'] - max bytes for the supervisord logfile before it is rotated rotated, default '50MB'

  • node['supervisor']['logfile_backups'] - the number of backups of that logfile to keep, default 10

  • node['supervisor']['loglevel'] - the minimum severity for those log messages, default 'info'

  • node['supervisor']['minfds'] - The minimum number of file descriptors that must be available before supervisord will start successfully.

  • node['supervisor']['minprocs'] - The minimum number of process descriptors that must be available before supervisord will start successfully.

  • node['supervisor']['version'] - Sets the version of supervisor to install, must be 3.0+ to use minprocs and minfds.

  • node['supervisor']['socket_file'] - location of supervisor socket file.

  • node['supervisor']['ctlplugins'] - entries for supervisorctl plugins. For instance, to install serialrestart, you'd manually add this to your config:

    [ctlplugin:serialrestart]
supervisor.ctl_factory = supervisorserialrestart.controllerplugin:make_serialrestart_controllerplugin

    Which can be achieved using

    node.default['supervisor']['ctlplugins'] = ({
 'serialrestart'=> 'supervisorserialrestart.controllerplugin:make_serialrestart_controllerplugin'
 })
