Chef on Vagrant Box: Can't find encrypted data bag secret

Question

When provisioning a vagrant box with (hosted-)chef I get the following error:

No such file or directory - file not found '/tmp/encrypted_data_bag_secret'

Here is the call causing the error:

ssl = Chef::EncryptedDataBagItem.load("ssl", s[:id])

I also can't find the encrypted_data_bag_secret in /etc/chef where it normally resides on my other servers.

Am I missing a config which uploads the data bag secret?

Here's the rest of the stack trace:

Answer 1

When provisioning a vagrant box, you have to provide a path to your data bags secret key, if you want to use encrypted data bags.

config.vm.provision :chef_solo do |chef|
  [...]
  chef.encrypted_data_bag_secret_key_path = '/etc/chef/encrypted_data_bag_secret'
  [...]
end

Answer 2

Quick amendment to Thomas Obermüller's response to Draco Ater's answer above. In Vagrant 1.5.1 through Vagrant 1.6.5 (and possibly earlier than 1.5.1; I didn't try it), there are a couple of changes:

1. chef.encrypted_data_bag_secret is deprecated, and setting it has no effect.
2. Vagrant puts the encrypted key at /tmp/vagrant-chef-2/encrypted_data_bag_secret_key, instead of defaulting to /etc/chef/encrypted_data_bag_secret as it did initially.
