[chef] Re: Re: how to debug errors

[Ran Tavory < >]

as I mentioned, I'm learning it... now I know about the directory... thanks!

BTW, I haven't found a list of all available "commands" or not sure how should I call them, such as cookbook_file, bash, directory etc. Could someone pls share a link?

Run with chef debug logging enable to see the full command output/error:

   chef-solo -l debug ....

Also using bash to make a directory and the copy a file isn't what I'd consider the 'chef' way of doing things.

directory node[:wars] do
 recursive true
 mode '0755'
end

etc.

-ash
