Greetings good people,

Beginner here. Just wanted to find out as to how I'd go about debugging the puppet code? For an example if I have mistyped the code in a manifiest/template/module whats the best way to debug it in general?

Please help out gentlemen.

Many thanks in advance

I'll assume you know the fundamentals of Puppet.

  • Install the Puppet vim syntax highlighter if you're a vim user. Syntax highlighting picks up a lot of typos.

  • Set up the puppetlabs_spec_helperref.

  • Write rspec-puppet tests.

Once all this is set up:

This command will find typos in your files:

bundle exec rake validate

This command will check your code for stylistic issues:

bundle exec rake lint

This command will run your rspec-puppet tests:

bundle exec rake spec

It'll probably be quite a learning curve just to set all of this up if you're a beginner. Once you get there, however, you won't look back.

If all that's too much for you:

Check a manifest file for syntax errors:

puppet parser validate <your_file.pp>

Check an ERB file for errors:

erb -P -x -T '-' <your_file.erb> | ruby -c

I would also add using one of the IDE environments... either geppetto, or the intelliJ/Netbeans plugins for code completion, invalid syntax highlighting, and code navigation

Well I can't say that because I'm a vim user. :)

If that's answered your question could you also mark the issue as resolved, thanks.

Thanks again gentlemen. Alex: Tied resolving the thread as you suggested but Im afraid that I cant seem to find the option to do so. I can close of course but it will delete the question off I reckon? Please advice.
