chef-server cookbook

This cookbook configures a system to be a standalone Chef 12+ Server. It will install the appropriate platform-specific chef-server Omnibus package from Package Cloud and perform the initial configuration.

It is not in the scope of this cookbook to handle more complex Chef Server topologies like 'tiered' or 'ha'. Nor is it in the scope of this cookbook to install and configure premium features or other add-ons. For clustered Chef Server deployments, see chef-server-cluster. For primitives for installing chef-server-core or other Chef Server add-ons, see chef-ingredient.

Requirements

Platforms

• RHEL 6+
• Ubuntu 14.04+

Chef

• Chef 12.7+

Cookbooks

• chef-ingredient >= 2.1.10

Attributes

The attributes used by this cookbook are under the chef-server name space.

Previous versions of this cookbook had several other attributes used to control the version of the Chef Server package to install. This is deprecated.

Previous versions of this cookbook used configuration as a Hash. This is now deprecated and the configuration should be specified as a String. This must include newlines for each of the configuration items.

See https://docs.chef.io/config_rb_server.html for configuration options for Chef Server. For a complete list of product names for use in the add-ons attribute see https://github.com/chef/mixlib-install/blob/master/PRODUCT_MATRIX.md

Recipes

This section describes the recipes in the cookbook and how to use them in your environment.

default

This recipe:

• Installs the appropriate platform-specific chef-server Omnibus package from our Package Cloud repository
• Creates the initial /etc/chef-server/chef-server.rb file.
• Performs initial system configuration via chef-server-ctl reconfigure.
• Updates the /etc/hosts file with the api_fqdn if that FQDN cannot be resolved.

addons

Chef addons are premium features that can be installed on the Chef Server with the appropriate license. If there are under 25 nodes managed, or a paid subscription license, addons can be installed.

This recipe iterates through the node['chef-server']['addons'] attribute and installs and reconfigures all the packages listed.
Note: When multiple add-ons are installed, and one of them has version locked, either lock versions of all packages (best practice) or set version to nil Example:
default['chef-server']['addons'] = {'chef-manage' => '2.5.0', reporting: nil}

Install Methods

Bootstrap Chef (server) with Chef (solo)

The easiest way to get a Chef Server up and running is to install chef-solo (via the chef-client Omnibus packages) and bootstrap the system using this cookbook:

# install chef-solo
curl -L https://www.chef.io/chef/install.sh | sudo bash
# create required bootstrap dirs/files
sudo mkdir -p /var/chef/cache /var/chef/cookbooks
# pull down this chef-server cookbook
wget -qO- https://supermarket.chef.io/cookbooks/chef-server/download | sudo tar xvzC /var/chef/cookbooks
# pull down dependency cookbooks
for dep in chef-ingredient
do
  wget -qO- https://supermarket.chef.io/cookbooks/${dep}/download | sudo tar xvzC /var/chef/cookbooks
done
# GO GO GO!!!
sudo chef-solo -o 'recipe[chef-server::default]'

If you need more control over the final configuration of your Chef Server instance you can create a JSON attributes file and set underlying configuration via the node['chef-server']['configuration'] attribute. See the attributes file.

Then pass this file to the initial chef-solo command:

chef-solo -j /tmp/dna.json

Configuring Chef Server

You can read all about Chef Server's configuration options on the Chef Documentation site.

Specify configuration using the node['chef-server']['configuration'] attribute as a string. Each configuration item should be separated by newlines. This string will be rendered exactly as written in the configuration file, /etc/opscode/chef-server.rb. For example, if we want to change the notification email, we could do this in a wrapper cookbook:

node.default['chef-server']['configuration'] = "notification_email '[email protected]'"

Or in a dna.json file:

{
  "chef-server": {
    "configuration": "notification_email '[email protected]'"
  }
}

Or, for multiple configuration settings, such as the notification email and the cache size for nginx, this uses a heredoc:

node.default['chef-server']['configuration'] = <<-EOS
notification_email '[email protected]'
nginx['cache_max_size'] = '3500m'
EOS

In a dna.json file, we need to insert a \n newline character.

{
  "chef-server": {
    "configuration": "notification_email '[email protected]'\nnginx['cache_max_size'] = '3500m'"
  }
}

Applying configuration changes

The chef-server-ctl command is the administrative interface to the Chef Server. It has its own documentation. Various administrative functions provided by chef-server-ctl are not in the scope of this cookbook. Special/customized needs should be managed in your own cookbook.

As this cookbook uses the chef-ingredient cookbook, its resources can be used to manage the Chef Server installation. The default recipe in this cookbook exposes chef_ingredient[chef-server] as a resource that can be sent a :reconfigure action from your own cookbooks. The omnibus_service resource can be used to manage the underlying services for the Chef Server. See the chef-ingredient cookbook for more information.

If on convergence you are observing an error in the form of:

             ================================================================================
             Error executing action `run` on resource 'execute[chef-manage-reconfigure]'
             ================================================================================

             STDOUT: To use this software, you must agree to the terms of the software license agreement.

when using proprietary Chef products, you will need to make sure to accept the Chef Master License and Services Agreement (Chef MSLA).

Proprietary Chef products—such as Chef Compliance, Chef Delivery, Chef Analytics, Reporting, and the Chef Management Console—are governed by the Chef MLSA. The Chef MLSA must be accepted when installing or reconfiguring the product. Chef ingredient added the accept_license property to provide a way to automate this. This fix adds the attribute ['chef-server']['accept_license']. The default value is false. Individuals must explicitly change the value to true in their environment to accept the license. Make sure you set the node attribute ['chef-server']['accept_license'] = true to resolve this error.
