Chef attributes value reuse

Question

Versions :

• Server 12
• chef client 12.13.37

I have an attribute file with a lot of url references but all to the same server. I'd like to reference a base url to build up the full path. Then if the source server changes I just change the top attribute.

original

default['cookbook'][1.1]['zipurl']  = 'http://server/something/version/SERVER.zip'

planned

default['cookbook'][1.1]['packagesurl'] = 'http://server/'

default['cookbook'][1.1]['zipurl']  = '"#{default['cookbook'][version]['packagesurl']}"something/version/SERVER.zip'

It compiles and uploads ok but the chef run returns the following :

"#default{['cookbook'][version]['packagesurl']}something/version/server.zip" is not a valid `source` parameter for remote_file. `source` must be an absolute URI or an array of URIs.

probably some basic syntax wrong ...

I looked in the attributes of some of the supermarket public cookbooks and they call use the full paths so this might not be possible.

You need to use double quotes (") for #{} interpolation to work in Ruby. Also check out poise-derived for another option that might fix a few footguns before you find them yourself.
