pry() debugging function
When compiling puppet manifests it is often frustrating to find subtle variable parsing or ordering problems. Introspecting specific resource parameters at a given point is also difficult. This function makes those two tasks easier by using pry.
gem install pry and call
pry() at some point during a catalog
compile by adding it to the specific line in a manifest where you would like to
inspect the compilation state, and run the process doing the compilation in the
foreground. Puppet will drop into a debugging shell in the
Puppet::Parser::Scope object at the time of the function call. A few helpful
tips will be printed when the shell is first entered.
When used in manifests during rspec-puppet compilation, the pry REPL will appear in the shell running the spec tests. When used with a puppet master, the master process must be run in the forground with
puppet master --no-daemonize --verbose to view the debug shell. If a daemonized master process enters the debug shell,
kill must be used to exit the debug shell.
