ssl-key-vault cookbook

This cookbook manages OpenSSL key pairs, using chef-vault to share and store private keys.

This cookbook's home is at https://github.com/3ofcoins/ssl-key-vault/

Requirements

Usage

1. Generate a self-signed key or a secret key and certificate.

2. Store the private key in chef-vault. The name should be set to ssl-key-key.name.:

   $ ruby -rjson -e 'puts JSON[Hash[Hash[*ARGV].map { |k,v| [k, File.read(v)] }]]' -- \
       chain.pem example.com.chain.pem \
       crt example.com.crt \
       csr example.com.csr \
       key example.com.key \
       pem example.com.pem \
       > example.com.json
   

   $ knife encrypt create certs --mode client \
     --search 'QUERY' --admins '' \
     --name ssl-key-example_com \
     --json /path/to/example.com.json
   

   Either add Chef server's admin API users to the --admins, or make the key otherwise accessible to yourself in future (e.g. with knife-briefcase).

3. Add the certificate to node's ssl_certificates attribute (key is key's name, and value is full certificate):

default_attributes :ssl_certificates => {
  'example.com' => true
}

4. Add recipe[ssl-key-vault] to node's run list.

The key will be stored in /etc/ssl/private/key.name.key, and certificate in /etc/ssl/certs/key.name.pem.

TODOs & questions

I don't have much of idea currently how to add tests, with chef-vault, encrypted data bags, and such.
