Thanks for the response

I do this already extensively in cookbooks and was hoping that I could extend to roles -- but such be life.

No, nor would this work in the ruby format. Role data must be purely static. You can do things like this in cookbooks though.

I use JSON based role files and for better or worse use them often  for attribute definition.

I have recently tried to perform variable interpolation like this

    "default_attributes": {

        "foo": {

            "server": "extra.#{node['fqdn']}"

          }

 

I was not surprised that this DID NOT work and that I got 'extra.#{node['fqdn']}' rather than an interpolated string.

Is there any way to interpolate in JSON role files?

Thanks
