(hello Solr, is your index up to date?) run Chef Client, unless its already running. is the client up to date? (maybe start over if it isnt)check system configuration in great detail. is the right version of Ruby installed? (maybe build it!) create a system user specifically for the application. build folders shared between deploys. forward the running SSH agent in order to pull code over SSH. install gems from the Gemfile in the versioned directory. does the application need database access? which one? does it have credentials?(maybe create db/credentials) run any necessary db migrations. write out a unicorn configuration file. write out an init.d script. replace the current symlink. attempt a graceful restart of the Ruby application. then, possibly, consider moving on to routing. 9.
