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.

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
  ssl_chain cert.chain_path
end

Partial Templates

This cookbook contains partial templates that you can include in your virtualhost templates to enable and configure the SSL protocol. These partial templates are available:

apache.erb: For Apache httpd web server.
nginx.erb: For nginx web server.

Partial Templates Parameters

Parameter	Default	Description
ssl_cert	`nil`	Public SSL certificate full path.
ssl_key	`nil`	Private SSL key full path.
ssl_chain	`nil`	Intermediate SSL certificate chain full path (apache only) (optional).
ssl_compatibility	node attribute	SSL compatibility level (See below).

Apache Partial Template

Using `web_app` Definition

If you are using the web_app definition, you should pass the @params variables to the partial template:

web_app 'my-webapp-ssl' do
  docroot node['apache']['docroot_dir']
  server_name cert.common_name
  # [...]
  ssl_key cert.key_path
  ssl_cert cert.cert_path
  ssl_chain cert.chain_path
end

<%# included by web_app definition %>
<VirtualHost *:443>
  ServerName <%= @params[:server_name] %>
  DocumentRoot <%= @params[:docroot] %>
  <%# [...] %>

  <%= render 'apache.erb', cookbook: 'ssl_certificate', variables: @params.merge(node: node) %>
</VirtualHost>

Using `template` Resource

cert = ssl_certificate 'my-webapp-ssl'
template File.join(node['apache']['dir'], 'sites-available', 'my-webapp-ssl') do
  source 'apache_vhost.erb'
  # [...]
  variables(
    # [...]
    ssl_key: cert.key_path,
    ssl_cert: cert.chain_combined_path,
    ssl_chain: cert.chain_path
  )
end

You can include the partial template as follows:

<%# included by template resource %>
<VirtualHost *:443>
  ServerName <%= @server_name %>
  DocumentRoot <%= @docroot %>
  <%# [...] %>

  <%= render 'apache.erb', cookbook: 'ssl_certificate' %>
</VirtualHost>

Nginx Partial Template

If you are using nginx template, we recommended to use the SslCertificate#chain_combined_path path value to set the ssl_cert variable instead of SslCertificate#cert_path. That's to ensure we always include the chained certificate if there is one. This will also work when there is no chained certificate.

cert = ssl_certificate 'my-webapp-ssl'
template File.join(node['nginx']['dir'], 'sites-available', 'my-webapp-ssl') do
  source 'nginx_vhost.erb'
  # [...]
  variables(
    # [...]
    ssl_key: cert.key_path,
    ssl_cert: cert.chain_combined_path
  )
end

See examples below.

Securing Server Side TLS

You can change the SSL compatibility level based on the TLS recommendations in the Mozilla wiki using the ssl_compatibility template parameter:

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
  ssl_chain cert.chain_path
  ssl_compatibility :modern # :modern | :intermediate | :old
end

You can also use the node['ssl_certificate']['service']['compatibility'] node attribute to change the compatibility level used by default.

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):

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
  ssl_chain cert.chain_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

See templates documentation.

Nginx Example

Minimal nginx example using community nginx cookbook:

cert = ssl_certificate 'my-webapp' do
  notifies :restart, 'service[nginx]'
end

# Create a 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_chain_combined attributes.
  # You can use the *nginx.erb* partial template as shown below.
  source 'nginx_vhost.erb'
  mode 00644
  owner 'root'
  group 'root'
  variables(
    name: 'my-webapp-ssl',
    server_name: 'ssl.onddo.com',
    docroot: '/var/www',
    # [...]
    ssl_key: cert.key_path,
    ssl_cert: cert.chain_combined_path
  )
  notifies :reload, 'service[nginx]'
end

# Enable the virtualhost
nginx_site 'my-webapp-ssl' do
  enable true
end

# publish the certificate to an attribute, it may be useful
node.set['web-app']['ssl_cert']['content'] = cert.cert_content

Here's a nginx template example using the nginx.erb partial template:

<%# nginx_vhost.erb %>
server {
  server_name <%= @server_name %>;
  listen 443;
  # Path to the root of your installation
  root <%= @docroot %>;

  access_log <%= node['nginx']['log_dir'] %>/<%= @name %>-access.log combined;
  error_log  <%= node['nginx']['log_dir'] %>/<%= @name %>-error.log;

  index index.html;
  <%# [...] %>

  <%= render 'nginx.erb', cookbook: 'ssl_certificate' %>
}

See templates documentation.

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

Creating a Certificate with Subject Alternate Names

domain = 'mysite.com'
# SAN for mysite.com, foo.mysite.com, bar.mysite.com, www.mysite.com
node.default[domain]['ssl_cert']['subject_alternate_names'] =
  [domain, "foo.#{domain}", "bar.#{domain}", "www.#{domain}"]

ssl_certificate 'mysite.com' do
  namespace node[domain]
  key_source 'self-signed'
  cert_source 'self-signed'
end

The subject_alternate_names parameter adds DNS values by default. You can also include other kind of values using a colon to separate the type from the value:

domain = 'mysite.com'
node.default[domain]['email'] = 'email@example.com'
node.default[domain]['ssl_cert']['subject_alternate_names'] =
  [
    'email:copy',
    "email:my@#{domain}",
    "URI:http://#{domain}/",
    'IP:192.168.7.1',
    'IP:13::17',
    'RID:1.2.3.4',
    'otherName:1.2.3.4;UTF8:some other identifier'
  ]

ssl_certificate 'mysite.com' do
  namespace node[domain]
  key_source 'self-signed'
  cert_source 'self-signed'
end

See the x509v3_config manual page for more information.

Reading Key, Certificate and Intermediary from a Data Bag

cert_name = 'chain-data-bag'
node.default[cert_name]['ssl_key']['source'] = 'data-bag'
node.default[cert_name]['ssl_key']['bag'] = 'ssl'
node.default[cert_name]['ssl_key']['item'] = 'key'
node.default[cert_name]['ssl_key']['item_key'] = 'content'
node.default[cert_name]['ssl_key']['encrypted'] = true
node.default[cert_name]['ssl_cert']['source'] = 'data-bag'
node.default[cert_name]['ssl_cert']['bag'] = 'ssl'
node.default[cert_name]['ssl_cert']['item'] = 'cert'
node.default[cert_name]['ssl_cert']['item_key'] = 'content'
node.default[cert_name]['ssl_chain']['name'] = 'chain-ca-bundle.pem'
node.default[cert_name]['ssl_chain']['source'] = 'data-bag'
node.default[cert_name]['ssl_chain']['bag'] = 'ssl'
node.default[cert_name]['ssl_chain']['item'] = 'chain'
node.default[cert_name]['ssl_chain']['item_key'] = 'content'

ssl_certificate 'chain-data-bag' do
  namespace cert_name
end

Creating a Certificate from a Certificate Authority

ca_cert = '/usr/share/pki/ca-trust-source/anchors/CA.crt'
ca_key = '/usr/share/pki/ca-trust-source/anchors/CA.key'

cert = ssl_certificate 'test' do
  namespace node['test.com']
  key_source 'self-signed'
  cert_source 'with_ca'
  ca_cert_path ca_cert
  ca_key_path ca_key
end

Reading the CA Certificate from a Chef Vault Bag

In this example, we read the CA certificate from a Chef Vault and use it to generate the shelf-signed certificates:

# Create the CA from a Chef Vault bag

ca_cert = ssl_certificate 'ca.example.org' do
  common_name 'ca.example.org'
  source 'chef-vault'
  bag 'ssl'
  item 'ca_cert'
  key_item_key 'key_content'
  cert_item_key 'cert_content'
end

ssl_certificate 'example.org' do
  cert_source 'with_ca'
  ca_cert_path ca_cert.cert_path
  ca_key_path ca_cert.key_path
end

The vault bag content:

{
  "id": "ca_cert",
  "key_content": "-----BEGIN RSA PRIVATE KEY-----\nMIIE [...]",
  "cert_content": "-----BEGIN CERTIFICATE-----\nMIIE [...]"
}

The knife command to create the vault bag item:

$ knife vault create ssl ca_cert [...]

Managing Certificates Via Attributes

Sometimes you may want to use only node attributes to manage some of your SSL Certificates (instead of the ssl_certificate resource). You can do it using the ssl_certificate::attr_apply recipe and configuring them inside the node['ssl_certificate']['items'] array:

run_list(
  'recipe[ssl_certificate::attr_apply]'
)
override_attributes(
  'ssl_certificate' => {
    'items' => [
      {
        'name' => 'domain.com',
        'dir' => '/etc/nginx/ssl',
        'item' => 'domain_com',
        'source' => 'chef-vault',
        'bag' => 'ssl-vault',
        'key_item_key' => 'key',
        'cert_item_key' => 'cert',
        'chain_item_key' => 'chain',
        'chain_source' => 'chef-vault',
        'chain_bag' => 'ssl-vault',
        'chain_item' => 'domain_com',
        'chain_name' => 'domain.com.chain.pem'
      }
    ]
  }
)

Testing
