[chef] How to override node attribute with lazy value?

[Greg Barker < >]

The chef-server readme shows how to override nginx attributes. However, it doesn't seem to work like I want it to when I do:

node.override["chef-server"]["configuration"]["nginx"]["ssl_certificate"] = "/etc/pki/tls/certs/#{node[:fqdn]}.pem"

node[:fqdn] is being updated during my chef run using the hostname cookbook, and so using the above results in an error because chef-server ends up looking for /etc/pki/tls/certs/localhost.pem (the old hostname), when it should instead be using /etc/pki/tls/certs/mynode.mycompany.com.pem.

So I think I want something like the following, but this doesn't work. What's the right way to do it?

node.override["chef-server"]["configuration"]["nginx"]["ssl_certificate"] = lazy { "/etc/pki/tls/certs/#{node[:fqdn]}.pem" }

Thanks,
Greg
