Daemon Kit - RubyKaigi 2009

Facing your daemons

Ruby daemons are a PITA  Tired of brittle daemons ?  Tired of running blind ?  Tired of setting up monitoring ?  Tired of worrying about logging ?  Tired of missing pid files ?

daemonkit ?  Opionated Framework for Ruby daemons  Keep things DRY  Generators to help make things simple  Rake tasks to help keep things simple

Multiple environments  Development  Be noisy, break early, break hard  Testing  Staging  Production  Be quiet, stay alive, recover easily

Don't worry about pid files  Managed for you  Infered or explicit files  Great for controlling clusters  Handles stale pid files

Don't worry about logging  Multiple levels  Syslog support  Log rotation friendly (HUP)

Don't worry about configuration  Simple YAML config files  Ondemand hashes  Environmentaware configuration  Defaults and environment specific overrides

Don't worry about monitoring  Generate monit/god configuration files via rake

Don't worry about silent death  Safety nets for threads  Hoptoad integration  Exception emails  Change logging levels with SIGUSR1/SIGUSER2

Generators accelarate  AMQP consumer  Nanite agent  XMPP bot  Cron daemon  Ruote remote participants   $ daemon_kit mydaemon i amqp

Easy deployment  Custom capistrano recipe tailored for daemons  Awaiting vlad contribution :)   $ daemon_kit mydaemon d capistrano  $ ./script/generate deploy_capistrano

Suitable for networking  EventMachine is a dependency  AMQP uses EM  Scheduler uses EM  XMPP to use EM (under construction)

Looking forward  RobustThread support  Bundled thread/fibre pool implementation  Sys V Init script generation  Bleakhouse support  Privilege dropping & chroot'ing
