Cannot use chef provisioning in vagrant - vagrant

Question

I created a basic vagrant box and config provisioning as below
config.vm.provision :chef_solo do |chef|
chef.add_recipe "apache2"
chef.json = { :apache => { :default_site_enabled => true } }
end
I also add cookbook to my project
git submodule add https://github.com/svanzoest-cookbooks/apache2/ cookbooks/apache2
But when I run vagrant provision, I get this

Maybe iptables cookbook is required, so I add it. And then I get this message

logrotate cookbook is required?
Why does it continuously require cookbook? What is metadata here?
Can anyone help me?

Answer 1

Cookbooks can have dependencies to other cookbooks. This allows them to rely on functionality provided by these other cookbooks.
In your case, your apache2 cookbook depends on the iptables and the logrotate cookbooks. You can check this in each cookbook's metadata.rb file. In case of your apache2 cookbook, you can find the metadata.rb file on GitHub.
Note that cookbooks can also have recursive dependencies, i.e. they can have further dependencies which must all be fulfilled. Because if this, it is often recommended to manage your cookbooks with a tool like Berkshelf or Librarian which can download all cookbook dependencies automatically and consistent.
