Description
The main purpose of this cookbook is to make it easy for other cookbooks to support SSL. With the resource included, you will be able to manage certificates reading them from attributes, data bags or chef-vaults. Exposing its configuration through node attributes.
Much of the code in this cookbook is heavily based on the SSL implementation from the owncloud cookbook.
Requirements
Works on any platform with OpenSSL Ruby bindings installed, which are a requirement for Chef anyway.
Resources
ssl_certificate
Creates a SSL certificate.
By default the resource will create a self-signed certificate, but a custom one can also be used. The custom certificate can be read from several sources:
- Attribute
- Data Bag
- Encrypted Data Bag
- Chef Vault
- File
ssl_certificate actions
-
create
: Creates the SSL certificate.

Templates
This cookbook includes a simple VirtualHost template which can be used by the web_app
definition from the apache2 cookbook:
cert = ssl_certificate "my-webapp" do namespace node["my-webapp"] notifies :restart, "service[apache2]" end include_recipe "apache2" include_recipe "apache2::mod_ssl" web_app "my-webapp" do cookbook "ssl_certificate" server_name cert.common_name docroot # [...] # [...] ssl_key cert.key_path ssl_cert cert.cert_path end
Usage
Including the cookbook
You need to include this recipe in your run_list
before using the ssl_certificate
resource:
{ "name": "onddo.com", [...] "run_list": [ [...] "recipe[ssl_certificate]" ] }
You can also include the cookbook as a dependency in the metadata of your cookbook:
# metadata.rb depends "ssl_certificate"
One of the two is enough. No need to do anything else. Only use the ssl_certificate
resource to create the certificates you need.
A Short Example
cert = ssl_certificate "webapp1" do namespace node["webapp1"] # optional but recommended end # you can now use the #cert_path and #key_path methods to use in your web/mail/ftp service configurations log "WebApp1 certificate is here: #{cert.cert_path}" log "WebApp1 private key is here: #{cert.key_path}"
Namespaces
The ssl_certificate
namespace attribute is a node attribute path, like for example node["onddo.com"]
, used to configure SSL certificate defaults. This will make easier to integrate the node attributes with the certificate creation matters. This means you can configure the certificate creation through node attributes.
When a namespace is set in the resource, it will try to read the following attributes below the namespace (all attributes are optional):
<table>
<tr>
<th>Attribute</th>
<th>Description</th>
</tr>
<tr>
<td><code>namespace["common_name"]</code></td>
<td>Server name or Common Name, used for self-signed certificates (uses <code>node["fqdn"]</code> by default).</td>

<td><em>Country</em>, used for self-signed certificates.</td>
</tr>
<tr>
<td><code>namespace["city"]</code></td>

Examples
Apache Examples
Apache web_app
example using community apache2 cookbook and node attributes:
node.default["my-webapp"]["common_name"] = "onddo.com" node.default["my-webapp"]["ssl_cert"]["source"] = "self-signed" node.default["my-webapp"]["ssl_key"]["source"] = "self-signed" # we need to save the resource variable to get the key and certificate file paths cert = ssl_certificate "my-webapp" do # we want to be able to use node["my-webapp"] to configure the certificate namespace node["my-webapp"] notifies :restart, "service[apache2]" end include_recipe "apache2" include_recipe "apache2::mod_ssl" web_app "my-webapp" do # this cookbook includes a virtualhost template for apache2 cookbook "ssl_certificate" server_name cert.common_name docroot # [...] # [...] ssl_key cert.key_path ssl_cert cert.cert_path end
Using custom paths:
my_key_path = "/etc/keys/my-webapp.key" my_cert_path = "/etc/certs/my-webapp.pem" # there is no need to save the resource in a variable in this case because we know the paths ssl_certificate "my-webapp" do key_path my_key_path cert_path my_cert_path end # Configure Apache SSL include_recipe "apache2::mod_ssl" web_app "my-webapp" do cookbook "ssl_certificate" # [...] ssl_key my_key_path ssl_cert my_cert_path end
Nginx Example
Minimal nginx
example using community nginx cookbook:
cert = ssl_certificate "my-webapp" do notifies :restart, "service[nginx]" end # Create virtualhost for nginx template File.join(node["nginx"]["dir"], "sites-available", "my-webapp-ssl") do # You need to create a template for nginx to enable SSL support # and read the keys from ssl_key and ssl_cert attributes # [...] variables( # [...] :ssl_key => cert.key_path, :ssl_cert => cert.cert_path ) notifies :reload, "service[nginx]" end # publish the certificate to an attribute, it may be useful node.set["web-app"]["ssl_cert"]["content"] = cert.cert_content
Reading The Certificate From Attributes
The SSL certificate can be read from an attribute directly:
# Setting the attributes node.default["mysite"]["ssl_key"]["content"] = "-----BEGIN PRIVATE KEY-----[...]" node.default["mysite"]["ssl_cert"]["content"] = "-----BEGIN CERTIFICATE-----[...]" # Creating the certificate ssl_certificate "mysite" do common_name "cloud.mysite.com" namespace node["mysite"] # this will read the node["mysite"]["ssl_key"]["content"] and node["mysite"]["ssl_cert"]["content"] keys source "attribute" end
Alternative example using a namespace and node attributes:
# Setting the attributes node.default["mysite"]["common_name"] = "cloud.mysite.com" node.default["mysite"]["ssl_key"]["source"] = "attribute" node.default["mysite"]["ssl_key"]["content"] = "-----BEGIN PRIVATE KEY-----[...]" node.default["mysite"]["ssl_cert"]["source"] = "attribute" node.default["mysite"]["ssl_cert"]["content"] = "-----BEGIN CERTIFICATE-----[...]" # Creating the certificate ssl_certificate "mysite" do namespace node["mysite"] end
Reading The Certificate From a Data Bag
ssl_certificate "mysite" do common_name "cloud.mysite.com" source "data-bag" bag "ssl_data_bag" key_item "key" # data bag item key_item_key "content" # data bag item json key cert_item "cert" cert_item_key "content" encrypted true secret_file "/path/to/secret/file" # optional end
Alternative example using a namespace and node attributes:
# Setting the attributes node.default["mysite"]["common_name"] = "cloud.mysite.com" node.default["mysite"]["ssl_key"]["source"] = "data-bag" node.default["mysite"]["ssl_key"]["bag"] = "ssl_data_bag" node.default["mysite"]["ssl_key"]["item"] = "key" node.default["mysite"]["ssl_key"]["item_key"] = "content" node.default["mysite"]["ssl_key"]["encrypted"] = true node.default["mysite"]["ssl_key"]["secret_file"] = "/path/to/secret/file" node.default["mysite"]["ssl_cert"]["source"] = "data-bag" node.default["mysite"]["ssl_cert"]["bag"] = "ssl_data_bag" node.default["mysite"]["ssl_cert"]["item"] = "key" node.default["mysite"]["ssl_cert"]["item_key"] = "content" node.default["mysite"]["ssl_cert"]["encrypted"] = true node.default["mysite"]["ssl_cert"]["secret_file"] = "/path/to/secret/file" # Creating the certificate ssl_certificate "mysite" do namespace node["mysite"] end
Reading The Certificate From Chef Vault
ssl_certificate "mysite" do common_name "cloud.mysite.com" source "chef-vault" bag "ssl_vault_bag" key_item "key" # data bag item key_item_key "content" # data bag item json key cert_item "cert" cert_item_key "content" end
The same example, using a namespace and node attributes:
# Setting the attributes node.default["mysite"]["common_name"] = "cloud.mysite.com" node.default["mysite"]["ssl_key"]["source"] = "chef-vault" node.default["mysite"]["ssl_key"]["bag"] = "ssl_vault_bag" node.default["mysite"]["ssl_key"]["item"] = "key" node.default["mysite"]["ssl_key"]["item_key"] = "content" node.default["mysite"]["ssl_cert"]["source"] = "chef-vault" node.default["mysite"]["ssl_cert"]["bag"] = "ssl_vault_bag" node.default["mysite"]["ssl_cert"]["item"] = "key" node.default["mysite"]["ssl_cert"]["item_key"] = "content" # Creating the certificate ssl_certificate "mysite" do namespace node["mysite"] end
Reading The Certificate From Files
ssl_certificate "mysite" do common_name "cloud.mysite.com" source "file" key_path "/path/to/ssl/key" cert_path "/path/to/ssl/cert" end
The same example, using a namespace and node attributes:
# Setting the attributes
node.default["mysite"]["common_name"] = "cloud.mysite.com"
node.default["mysite"]["ssl_key"]["source"] = "file"
node.default["mysite"]["ssl_key"]["path"] = "/path/to/ssl/key"
node.default["mysite"]["ssl_cert"]["source"] = "file"
node.default["mysite"]["ssl_cert"]["path"] = "/path/to/ssl/cert"
# Creating the certificate
ssl_certificate "mysite" do
namespace node["mysite"]
end
Reading The Certificate From Different Places
You can also read the certificate and the private key from different places each:
ssl_certificate "mysite" do common_name "cloud.mysite.com" # Read the private key from chef-vault key_source "chef-vault" key_bag "ssl_vault_bag" key_item "key" # data bag item key_item_key "content" # data bag item json key # Read the public cert from a non-encrypted data bag cert_source "data-bag" cert_bag "ssl_data_bag" cert_item "cert" cert_item_key "content" cert_encrypted false end
The same example, using a namespace and node attributes:
# Setting the attributes node.default["mysite"]["common_name"] = "cloud.mysite.com" # Read the private key from chef-vault node.default["mysite"]["ssl_key"]["source"] = "chef-vault" node.default["mysite"]["ssl_key"]["bag"] = "ssl_vault_bag" node.default["mysite"]["ssl_key"]["item"] = "key" node.default["mysite"]["ssl_key"]["item_key"] = "content" # Read the public cert from a non-encrypted data bag node.default["mysite"]["ssl_cert"]["source"] = "data-bag" node.default["mysite"]["ssl_cert"]["bag"] = "ssl_data_bag" node.default["mysite"]["ssl_cert"]["item"] = "key" node.default["mysite"]["ssl_cert"]["item_key"] = "content" node.default["mysite"]["ssl_cert"]["encrypted"] = false # Creating the certificate ssl_certificate "mysite" do namespace node["mysite"] end
