class SyncWrap::BundledIyyovDaemon

Provision a source/bundle installed, Iyyov launched and monitored jruby daemon using a standard set of conventions. Can be used directly in the common case, or sub-classed as needed.

Two :sync_paths files are searched for deployment: a config.rb and a jobs.d/<name>.rb. If concrete or .erb variants of these are not found than an (empty) default/config.rb and a generic default/bundled_daemon.rb.erb are used. Again, these will work in the common case.

Host component dependencies: RunUser, <ruby>, Iyyov

Attributes

instance[RW]

An optional secondary instance name, useful if running more than one of 'name' on a host. (Default: nil)

name[W]

The daemon process name. (Default: SyncWrap::SourceTree#remote_dir)
