[chef] Re: Error running package and template resoource in ruby block

[Tyler Ball < >]

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::Package::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 and http://docs.chef.io/lwrp_custom_resource.html for more info on making an LWRP.

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.
