Class: Chef::Resource::Deploy

Inherits:
Chef::Resource show all
Defined in:
lib/chef/resource/deploy.rb

Overview

Deploy: Deploy apps from a source control repository.

Callbacks: Callbacks can be a block or a string. If given a block, the code is evaluated as an embedded recipe, and run at the specified point in the deploy process. If given a string, the string is taken as a path to a callback file/recipe. Paths are evaluated relative to the release directory. Callback files can contain chef code (resources, etc.)

end

#create_dirs_before_symlink(arg = nil) ⇒ Object

An array of paths, relative to your app’s root, where you expect dirs to exist before symlinking. This runs after #purge_before_symlink, so you can use this to recreate dirs that you had previously purged. For example, if you plan to use a shared directory for pids, and you want it to be located in $APP_ROOT/tmp/pids, you could purge tmp, then specify tmp here so that the tmp directory will exist when you symlink the pids directory in to the current release. Default: [“tmp”, “public”, “config”]

#symlink_before_migrate(arg = nil) ⇒ Object

A Hash of shared/dir/path => release/dir/path. This attribute determines which files in the shared directory get symlinked to the current release directory and where they go. Unlike map_shared_files, these are symlinked before any migration is run. For a rails/merb app, this is used to link in a known good database.yml (with the production db password) before running migrate. Default => “config/database.yml”

#symlinks(arg = nil) ⇒ Object

A Hash of shared/dir/path => release/dir/path. This attribute determines which files and dirs in the shared directory get symlinked to the current release directory, and where they go. If you have a directory $shared/pids that you would like to symlink as $current_release/tmp/pids you specify it as “pids” => “tmp/pids” Default => “public/system”, “pids” => “tmp/pids”, “log” => “log”
