Treetop not loaded with chef-solo and --why-run

[crawley]

When I try to run a recipe that depends on chef-solo-search on an omnibus Chef 11.8.0 install using "chef-solo ... -W", I get the following error. When I remove the "-W", it works.

this is by design in chef https://tickets.opscode.com/browse/CHEF-3319

If you can find the docs for how to detect chef whyrun mode, I'll throw in the code to give a more friendly error message.

If you want to run in why mode anyways, ensure that treetop is installed into chef's embedded ruby parts before you run chef-solo. (ssh into your server and /opt/chef/embedded/bin/gem install treetop I think)

I think you should just be able to check the config hash; i.e.

Chef::Config[:solo]

is set to true when chef-solo starts. Mobile: 0427 027 304

Sorry ... not enough coffee.

Try Chef::Config[:why_run]
