Why are you trying to write a recipe within a ruby block ? I can't see a  
use case (but tell me if you find one).

You may do the same thing directly within the recipe as they are ruby  
code too.

You could wrap the same logic you’re trying to do in an LWRP:

use\_inline\_resources

action :install do  
package "postgres" do  
version "9.3"  
action :install  
provider Chef::Provider:📦:Apt  
end

template "/etc/postgresql/9.3/main/pg\_hba.conf" do  
source "pg\_hba.conf.erb"  
mode 0660  
user "postgres"  
group "postgres"  
end

execute "createdb ucmsdb" do  
user "postgres"  
not\_if "psql --list | grep -v grep | grep ucmsdb", :user =\> "postgres"  
end  
end

Then leverage that in your recipe (you’ll have to write the resource too, which I’m going to leave to you):

custom\_postgres “installer” do  
action :install  
end

All 3 of the resources are already idempotent, so your node attribute isn’t needed. But if your real installer is more complicated you can add conditional checks inside the lightweight provider. They will not be executed until your resource is.

Read [https://docs.chef.io/lwrp\_custom\_provider.html](https://docs.chef.io/lwrp_custom_provider.html) [https://docs.chef.io/lwrp\_custom\_provider.html](https://docs.chef.io/lwrp_custom_provider.html) and [http://docs.chef.io/lwrp\_custom\_resource.html](http://docs.chef.io/lwrp_custom_resource.html) [http://docs.chef.io/lwrp\_custom\_resource.html](http://docs.chef.io/lwrp_custom_resource.html) for more info on making an LWRP.
