[chef] How to extend node[:apache][:listen_ports] from within another recipe?

[Torben Knerr < >]

Hi Chefs,

I'm trying to add another port to `node[:apache][:listen_ports]` from within my own recipe, e.g. like this:

```

if not node[:apache][:listen_ports].include? "8080"

  node.override[:apache][:listen_ports] = node[:apache][:listen_ports] << "8080"

end

```

This does not work really well as it requires another chef run to take effect. I assume this is because it runs _after_ the /etc/apache2/ports.conf template resource (from the apache2 recipe) has been created with the orginal `node[:apache][:listen_ports]` which did not contain port 8080 at that time yet.

I have also tried to notify the /etc/apache2/ports.conf template resource after adding port 8080 to the apache listen ports, but this didn't work as well:

```

ruby_block "update apache listen port" do

  block do

    node.override[:apache][:listen_ports] = node[:apache][:listen_ports] << "8080"

  end

  notifies :create, resources(:template => "#{node[:apache][:dir]}/ports.conf")

  not_if { node[:apache][:listen_ports].include? "8080" } 

end

```

I suspect the resource gets in fact notified, but still has the "outdated" state as it does not re-evaluate `node[:apache][:listen_ports]` now that port 8080 has been added.

Is there a way to do this in a single Chef run?

Thanks,

Torben
