Set node value from script output

Chef Infra (archive)

I need the output of a script to set a node value, from inside a cookbook. How would one do this?

Thanks.

You will have to call Chef::ShellOut (or something similar) from within a ruby_block resource.

Something like the following should work as well.

node[:myattribute] = %x[/usr/bin/myscript]

Would that persist in the chef db? Or would I have to set it each time?

Thanks for the help.

I think I've found it in the wiki:

node.set['myattribute'] = %x[/usr/bin/myscript]
