chef-server.rb Optional Settings

The chef-server.rb file contains all of the non-default configuration settings used by the Chef server. (The default settings are built-in to the Chef server configuration and should only be added to the chef-server.rb file to apply non-default values.) These configuration settings are processed when the chef-server-ctl reconfigure command is run, such as immediately after setting up the Chef server or after making a change to the underlying configuration settings after the server has been deployed. The chef-server.rb file is a Ruby file, which means that conditional statements can be used in the configuration file.

Note

The chef-server.rb file does not exist by default. To modify the settings for the Chef server, create a file named chef-server.rb in the /etc/opscode/ directory.

Note

This file was named private-chef.rb in previous versions of Enterprise Chef. After an upgrade to Chef server 12 from Enterprise Chef, the private-chef.rb file is symlinked to chef-server.rb. The private-chef.rb file is deprecated, starting with Chef server 12.

Settings

The following sections describe the various settings that are available in the chef-server.rb file.

Note

When changes are made to the chef-server.rb file the Chef server must be reconfigured by running the following command:

$ chef-server-ctl reconfigure

General

This configuration file has the following general settings:

addons['install']
Default value: false.

Use this setting to ensure that migrated Open Source Chef servers are able to connect to the Chef server API. This value should be the same as the name of the organization that was created during the upgrade from Open Source Chef version 11 to Chef server version 12, which means it will be identical to the ORG_NAME part of the /organizations endpoint in Chef server version 12. Default value: the name of the organization specified during the upgrade process from Open Source Chef 11 to Chef server 12.
flavor
Default value: 'cs'.
install_path
The directory in which the Chef server is installed. Default value: '/opt/opscode'.

bookshelf

The bookshelf service is an Amazon Simple Storage Service (S3)-compatible service that is used to store cookbooks, including all of the files—recipes, templates, and so on—that are associated with each cookbook.

Note

To configure the server for external cookbook storage, updates are made to settings for both the bookshelf and opscode-erchef services.

This configuration file has the following settings for bookshelf:

bookshelf['access_key_id']
The access key identifier. (This is configurable and may be pointed at external storage locations, such as Amazon EC2. Four settings require configuration when pointing at an external cookbook storage location: bookshelf['vip'], for the endpoint used by the chef-client; bookshelf['external_url'], for the endpoint used by the Chef server; bookshelf['access_key_id'], for user access key; bookshelf['secret_access_key'], for secret key; and opscode_erchef['s3_bucket'], for the bucket name. Reconfigure the Chef server after changing these settings. Default value: generated by default.

bookshelf['port']
The port on which the service is to listen. Default value: 4321.
bookshelf['secret_access_key']
The secret key. (This is configurable and may be pointed at external storage locations, such as Amazon EC2.

Reconfigure the Chef server after changing these settings. Default value: generated by default.

ldap

This configuration file has the following settings for ldap:

ldap['base_dn']

The root LDAP node under which all other nodes exist in the directory structure. For Active Directory, this is typically cn=users and then the domain. For example:

'OU=Employees,OU=Domain users,DC=example,DC=com'

Default value: nil.

ldap['bind_dn']

The distinguished name used to bind to the LDAP server. The user the Chef server will use to perform LDAP searches. This is often the administrator or manager user. This user needs to have read access to all LDAP users that require authentication. The Chef server must do an LDAP search before any user can log in. Many Active Directory and LDAP systems do not allow an anonymous bind. If anonymous bind is allowed, leave the bind_dn and bind_password settings blank. If anonymous bind is not allowed, a user with READ access to the directory is required. This user must be specified as an LDAP distinguished name similar to:

'CN=user,OU=Employees,OU=Domainuser,DC=example,DC=com'

Default value: nil.

ldap['bind_password']
The password for the binding user. The password for the user specified by ldap['bind_dn']. Leave this value and ldap['bind_dn'] unset if anonymous bind is sufficient. Default value: nil.
ldap['group_dn']

The distinguished name for a group. When set to the distinguished name of a group, only members of that group can log in. This feature filters based on the memberOf attribute and only works with LDAP servers that provide such an attribute. In OpenLDAP, the memberOf overlay provides this attribute. For example, if the value of the memberOf attribute is CN=abcxyz,OU=users,DC=company,DC=com, then use:

ldap['group_dn'] = 'CN=user,OU=Employees,DC=example,DC=com'
ldap['host']
The name (or IP address) of the LDAP server. The hostname of the LDAP or Active Directory server. Be sure the Chef server is able to resolve any host names. Default value: ldap-server-host.
ldap['login_attribute']
The LDAP attribute that holds the user’s login name. Use to specify the Chef server user name for an LDAP user. Default value: sAMAccountName.
ldap['port']
An integer that specifies the port on which the LDAP server listens. The default value is an appropriate value for most configurations. Default value: 389 or 636 when ldap['encryption'] is set to :simple_tls.
ldap['ssl_enabled']

Cause the Chef server to connect to the LDAP server using SSL. Default value: false. Must be false when ldap['tls_enabled'] is true.

Note

Previous versions of the Chef server used the ldap['ssl_enabled'] setting to first enable SSL, and then the ldap['encryption'] setting to specify the encryption type. These settings are deprecated.

ldap['system_adjective']

A descriptive name for the login system that is displayed to users in the Chef server management console. If a value like “corporate” is used, then the Chef management console user interface will display strings like “the corporate login server”, “corporate login”, or “corporate password.” Default value: AD/LDAP.

Warning

This setting is not used by the Chef server. It is used only by the Chef management console.

ldap['timeout']
The amount of time (in seconds) to wait before timing out. Default value: 60000.
ldap['tls_enabled']

Enable TLS. When enabled, communication with the LDAP server is done via a secure SSL connection on a dedicated port. When true, ldap['port'] is also set to 636. Default value: false. Must be false when ldap['ssl_enabled'] is true.

Note

Previous versions of the Chef server used the ldap['ssl_enabled'] setting to first enable SSL, and then the ldap['encryption'] setting to specify the encryption type. These settings are deprecated.

In general, as the number of nodes increases, so does the amount of memory. The default value should work for many organizations with fewer than 25 nodes. For an organization with several hundred nodes, the amount of memory that is required often exceeds 3GB. Default value: nil, which is equivalent to 25% of the system memory or 1024 (MB, but this setting is specified as an integer number of MB in EC11), whichever is smaller.

Default value: 1000 (every 1000 documents).
opscode_solr4['max_field_length']
The maximum field length (in number of tokens/terms). If a field length exceeds this value, Apache Solr may not be able to complete building the index. Default value: 100000 (increased from the Apache Solr default value of 10000).
