Hi,
I just want to define a new LWRP to define some different defaults for
attributes of another LWRP.
Googling I’ve found this: http://stackoverflow.com/a/20732016/547195
And I’ve tried with: https://gist.github.com/gionn/6497eefdf9121c832b0e
But I am getting a recipe compile error:
Chef::Exceptions::InvalidResourceSpecification
You must specify resource_name'! /tmp/gionn_chef/cookbooks/cd-infrastructure/definitions/my_docker_container.rb:4:ininitialize’
Any suggestions?
Thanks!

This is not possible with LWRPs for reasons that are both complicated and very boring. Short version? You need to copy-pasta at least some of the upstream LWRP and build a wrapper around it instead of subclassing.

UGH.
An alternative could be to send a PR to the upstream cookbook with a
bunch of new node attributes defined to be used as default values for
the LWRP attributes?
Other suggestions?

for temporary workaround, you can write a helper method that takes a lwrp
name, and returns the lwrp objects (resource and provider) and you use that
to decorate/compose your new lwrp. in short use LWRPBase.from_file in your
library and pass it the file path (available from run context).
let us know if you need some code samples,
cheers
