IMPORTANT CHANGES
Please note the following important changes to the Chef cookbook(s) that coincide with the 0.10 release of Chef.
Cookbook Renaming
The cookbook formerly known as 'chef' has been split into two cookbooks:
- chef-client
- chef-server
So users have a clearer distinction about where to find recipes for managing Chef itself. The chef
cookbook will still be available for backwards compatibility reasons.
Attributes
The attributes are namespaced between using chef_client
and chef_server
. Several attributes have been renamed completely. See the attributes section below.
Paths
Path default values are selected by Platform according to the various distributions "best practice" preference. For example, major Linux distributions use the Filesystem Hierarchy Standard, which the attributes attempt to mimic. See the various platform specific path attributes in the attributes section.
Init Style
The default init style is chosen based on the platform. See the usage section on choosing an init style below.
Recipes
The recipes in the chef cookbook that are now in chef-server:
chef::bootstrap_server -> chef-server::rubygems-install
chef::server -> chef-server::default
chef::server_proxy -> chef-server::apache-proxy
See the recipes section below.
DESCRIPTION
This cookbook is used to configure a system to be a Chef Server. It has a few recipes, please read the recipes section below for information on what each one is used for.
REQUIREMENTS
Chef 0.10.0 or later is required. For earlier versions of Chef, see the chef
cookbook, version 0.99.0.
Platform
The Chef Server will work on a variety of platforms, however a Ubuntu or Debian is recommended when performing a RubyGems installation. Other platforms may work but are not as well tested.
The chef-server::default
recipe will work on any platform running the Chef Server, as it only compacts the CouchDB / views.
Cookbooks
The chef-server cookbook requires the following cookbooks from Opscode. Some are required for various init style options (bluepill, runit, daemontools):
- apt
- apache2
- runit
- couchdb
- chef-client
- chef-server
- openssl
- gecode
- java
- xml
- zlib
- erlang
- bluepill
- daemontools
- ucspi-tcp
- build-essential
ATTRIBUTES
The attributes used by this cookbook are under the chef_server
namespace.
When using the rubygems-install recipe, set the desired attributes using a JSON file. See RUBYGEMS_INSTALLATION for more information.
Platform Specific Attributes
The following attributes are chosen based on the platform and set accordingly. See the attributes/default.rb for default values by platform. The following platforms are supported:
- arch
- debian
- ubuntu
- redhat
- centos
- fedora
- openbsd
- freebsd
- mac_os_x
init_style
This attribute is used by the chef-server::rubygems-install
recipe. This specifies the type of init system used on the Chef Server. The attributes file will choose an init style based on the platform, but this can be overriden by specifying an alternate value.
Automatically determined values:
- arch - ArchLinux, and uses the appropriate rc.d and conf.d scripts out of the
chef
gem. - init - Debian, Ubuntu, Red Hat, CentOS and Fedora. Uses the appropriate /etc/default, /etc/sysconfig and /etc/init.d files out of the
chef
gem. - bsd - OpenBSD, FreeBSD and Mac OS X, does not actually set up any system startup daemon, but provides a log message for the administrator of further hints.
The following alternate init styles are available as well.
- runit - sets up the daemons and logging in /etc/sv/SERVICE with Opscode's
runit
cookbook. - daemontools - sets up the daemons and logging in /etc/sv/SERVICE with Opscode's
daemontools
cookbook. - bluepill - sets up the daemons in /etc/bluepill/SERVICE with Opscode's
bluepill
cookbook.
This cookbook does not yet support Upstart for Ubuntu/Debian, but that is planned for a future release, and will be specified via this attribute.
path
Used for the chef
user's home directory.
run_path
Location for PID files on systems using init scripts.
If init_style
is init
, this is used, and should match what the init script itself uses for the PID files.
cache_path
Location where the client will cache cookbooks and other data. Corresponds to Chef::Config[:file_cache_path]
configuration value.
backup_path
Location where backups of files replaced by Chef (template, cookbook_file
, etc), corresponds to the Chef::Config[:file_backup_path]
location.
Non-platform Specific Attributes
umask
Sets the umask for files created by the server process via Chef::Config[:umask]
in /etc/chef/server.rb
url
Full URI for the Chef Server. Used by Chef::Config[:chef_server_url]
configuration setting. Default is http://localhost:4000. If running chef-solr on a separate machine, configure it to the appropriate network accessible URL (e.g., http://chef.example.com:4000).
log_dir
Location where logs should be stored when initializing services via init scripts. Not used if init style is runit, daemontools or bluepill.
api_port
Port for the Server API service to listen on. Default 4000
.
webui_port
Port for the Server WebUI service to listen on. Default 4040
.
webui_enabled
As of version 0.8.x+, the WebUI part of the Chef Server is optional, and disabled by default. To enable it, set this to true.
solr_heap_size
Sets the amount of memory for the SOLR heap, default 256M.
validation_client_name
Set the name of the special client used to validate new clients. Default chef-validator
.
expander_nodes
Number of nodes to start up for the chef-expander (replacement for chef-solr-indexer in 0.10). Default is 1.
Server Proxy Attributes
The following attributes are used by the apache-proxy.rb
recipe, and are stored in the apache-proxy.rb
attributes file. They are under the node['chef_server']
attribute space.
doc_root
DocumentRoot for the WebUI. Also gets set in the vhost for the API, but it is not used since the vhost merely proxies to the server on port 4000.
ssl_req
This attribute can be used to set up a self-signed SSL certificate automatically using OpenSSL. Fields:
- C: country (two letter code)
- ST: state/province
- L: locality or city
- O: organization
- OU: organizational unit
- CN: canonical name, usually the fully qualified domain name of the server (FQDN)
- emailAddress: contact email address
This attribute should be a single string, fields separated by /.
css_expire_hours
Sets expiration time for CSS in the WebUI.
js_expire_hours
Sets expiration time for JavaScript in the WebUI.
RECIPES AND USAGE
This section describes the recipes in the cookbook and how to use them in your environment. This is focused on the Chef Server itself. To set up a Chef Server that will also be a Chef Client to itself, see the chef-client
cookbook.
default
Since the Chef Server itself typically runs the CouchDB service for the data store, the recipe will do a compaction on the Chef database and all the views associated with the Chef Server. These compactions only occur if the database/view size is more than 100Mb. It will use the configured CouchDB URL, which is http://localhost:5984
by default. The actual value used for the CouchDB server is from the Chef::Config[:couchdb_url]
, so this can be dynamically changed in the /etc/chef/server.rb config file.
apache-proxy
This recipe sets up an Apache2 VirtualHost to proxy HTTPS for the Chef Server API and WebUI.
The API will be proxied on port 443. If the WebUI is enabled, it will be proxied on port 444. The recipe dynamically creates the OpenSSL certificate based on the node['chef_server']['ssl_req']
attribute. It uses additional configuration for Apache to improve performance of the webui. The virtual host template is chef_server.conf.erb
. The DocumentRoot setting is used for the WebUI, but not the API, and is set with the attribute node['chef_server']['doc_root']
.
rubygems-install
ONLY FOR RUBYGEMS INSTALLATIONS. Do not use this recipe if you installed Chef from packages for your platform.
Use this recipe to "bootstrap" a system to become a Chef Server. This recipe does the following:
- Creates a
chef
user. - Installs CouchDB from package or source depending on the platform.
- Installs Java for the
chef-solr
search engine. - Installs RabbitMQ with the
chef-server::rabbitmq
recipe in the rabbitmq cookbook for the chef-expander consumer. - Installs Gecode with the
gecode
cookbook. On Debian/Ubuntu, Opscode's APT repository will be used. On other platforms, Gecode will be installed from source, which can take a long time. - Installs all the Server-related RubyGems.
- Creates the server configuration file
/etc/chef/server.rb
based on the configuration passed via JSON. - Creates the chef-solr configuration file,
/etc/chef/solr.rb
. - Sets up the
chef-server
,chef-solr
,chef-expander
services depending on theinit_style
attribute (see above).
Minimal JSON to use for the server configuration:
{
"chef_server": {
"url": "http://localhost.localdomain:4000",
},
"run_list": "recipe[chef-server::rubygems-install]"
}
Note that the chef-server-webui
is optional and can be enabled if desired.
{
"chef_server": {
"url": "http://localhost.localdomain:4000",
"webui_enabled": true
},
"run_list": "recipe[chef-server::rubygems-install]"
}
For more information see Bootstrap Chef RubyGems Installation on the Chef Wiki and the attributes section above.
