I keep getting the same error, no matter what I do. I am still a Chef-Noob.
Can anyone give me a clue?

The example as written is not compatible with chef-solo because it uses the search API. You can modify to hard-code the hostnames for the database server and application servers (presumably in your case both are just ['localhost']).

Thankyou so much!!!!!!!!!

I was able to locate and comment out the search code. Is there a
configuration based way to do this that would be less hacky?

Yes, both the database config in the django block and the nginx config accept a manual override (#host in the database, #hosts in the nginx) which if present will make it not fall back to search().

I was able to locate and comment out the search code. Is there a

Honestly, while that plugin is hella cool you are MUCH better off making a
decision one way or the other if a cookbook will or will not support solo.
The changes needed for that are so minimal that I can see no real need to
require something external that would have to track upstream changes in the
chef search API.

The logic needed to make a search-based recipe support solo can be boiled
down to:

  • Add attribute support for static definition of anything that would
    normally come back from a search result
  • Add a conditional logic to use static attributes instead of search results
  • Additionally, you can also favor static definitions of attributes over
    search results either by default (use static first and fallback to search
    if available) or as an attribute flag (node['foobar']['use_static'] = true)

I tend to prefer the second approach in the last bullet as I don't want an
accidental attribute overriding search results.

Regardless, as a side effect you get a much more community friendly
cookbook and one that is more testable.
