chef-server.rb 13 Optional Settings

[edit on GitHub]

Warning

This documentation covers Chef Infra Server 13, which is deprecated and will reach EOL on December 31, 2020. For Chef Infra Server 14, use the Chef Infra Server 14 Optional Settings documentation.

The /etc/opscode/chef-server.rb file contains all of the non-default configuration settings used by the Chef Infra Server. The default settings are built into the Chef Infra 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. The chef-server.rb file is a Ruby file, which means that conditional statements can be used within it.

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 Infra Server must be reconfigured by running the following command:

chef-server-ctl reconfigure

General

This configuration file has the following general settings:

addons['install']

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 may point at an external storage location, such as Amazon EC2. See AWS external bookshelf settings for more information on configuring external bookshelf. Default value: generated. As of Chef Server 12.14, this is no longer the preferred command.

Please use chef-server-ctl set-secret bookshelf access_key_id from the Secrets Management commands.

Use to configure request logging for the bookshelf service. Default value: false.

New in Chef Server 12.17.15.

bookshelf['external_url']

The base URL to which the service is to return links to API resources. Use :host_header to ensure the URL is derived from the host header of the incoming HTTP request. Default value: :host_header.

bookshelf['listen']

The IP address on which the service is to listen. Default value: 127.0.0.1.

bookshelf['log_directory']

The directory in which log data is stored. The default value is the recommended value. Default value: /var/log/opscode/bookshelf.

bookshelf['log_rotation']

The log rotation policy for this service. Log files are rotated when they exceed file_maxbytes. The maximum number of log files in the rotation is defined by num_to_keep. Default value:

{ 'file_maxbytes' => 104857600, 'num_to_keep' => 10 }
bookshelf['port']

The port on which the service is to listen. Default value: 4321.

bookshelf['secret_access_key']

The secret key. This may point at an external storage location, such as Amazon EC2. See AWS external bookshelf settings for more information on configuring external bookshelf. Default value: generated. As of Chef Server 12.14, this is no longer the preferred command.

Please use chef-server-ctl set-secret bookshelf secret_access_key from the Secrets Management commands.

bookshelf['storage_type']

Determines where cookbooks are stored. Default value: :filesystem.

In instances that require cookbooks to be stored within a SQL backend, such as in a high availability setup, you must set storage_type to :sql:

bookshelf['storage_type'] = :sql
bookshelf['stream_download']

Enable stream downloading of cookbooks. This setting (when true) typically results in improved cookbook download performance, especially with the memory usage of the bookshelf service and the behavior of load balancers and proxies in-between Chef Infra Client and the Chef Infra Server. Default value: true.

bookshelf['sql_connection_user']

The PostgreSQL user name in 'username@hostname' format (e.g. 'bookshelf@my_postgresql.postgres.database.azure.com'), where username would normally equal the value of bookshelf['sql_user'] (default: 'bookshelf'). This setting is required in an external Azure PostgreSQL database-as-a-service configuration. If set to nil, Chef Infra Server assumes that the database is not on Azure and the PostgreSQL connection will be made using the value specified in bookshelf['sql_user']. Default value: nil.

bookshelf['vip']

The virtual IP address. This may point at an external storage location, such as Amazon EC2. See AWS external bookshelf settings for more information on configuring external bookshelf. Default value: 127.0.0.1.

bootstrap

This configuration file has the following settings for bootstrap:

bootstrap['enable']

Indicates whether an attempt to bootstrap the Chef Infra Server is made. Generally only enabled on systems that have bootstrap enabled via a server entry. Default value: true.

compliance forwarding

The configuration file has the following settings for forwarding compliance requests using the chef server authentication system.

profiles['root_url']

If set, any properly signed requests arriving at /organizations/ORGNAME/owners/OWNER/compliance will be forwarded to this URL. This is expected to be a fully qualified resource, e.g. http://compliance.example.org/owners/OWNER/compliance.

dark_launch['sql_users']

Default value: true.

data_collector

This configuration file has the following settings for data_collector:

data_collector['root_url']

The fully qualified URL to the data collector server API. When present, it will enable the data collector in opscode-erchef. This also enables Chef Infra Server authenticated forwarding any properly signed requests arriving at /organizations/ORGNAME/data-collector to this URL with the data collector token appended. This is also target for requests authenticated and forwarded by the /organizations/ORGNAME/data-collector endpoint. For the forwarding to work correctly the data_collector['token'] field must also be set. For example, if the data collector in Chef Automate is being used, the URI would look like: http://my_automate_server.example.org/data-collector/v0/.

data_collector['proxy']

If set to true, Chef Infra Server will proxy all requests sent to /data-collector to the configured Chef Automate data_collector['root_url']. Note that this route does not check the request signature and add the right data_collector token, but just proxies the Automate endpoint as-is. Default value: nil.

data_collector['token']

Legacy configuration for shared data collector security token. When configured, the token will be passed as an HTTP header named x-data-collector-token which the server can choose to accept or reject. As of Chef Server 12.14, this is no longer the preferred command.

Please use chef-server-ctl set-secret data_collector token from the Secrets Management commands.

data_collector['timeout']

The amount of time (in milliseconds) before a request to the data collector API times out. Default value: 30000.

data_collector['http_init_count']

data_collector['ibrowse_options']

An array of comma-separated key-value pairs of ibrowse options for the HTTP connection pool that is used by the data collector. Default value: ”[{connect_timeout, 10000}]“.

data_collector['health_check']

A boolean that controls whether the data collector health is included in the overall health at the _status endpoint. When set to true, Chef Infra Server will report that healthy front end Chef HA cluster members have failed when the data_collector[‘root_url’] cannot be reached. As a result, the load balancer will remove those members from the load balancer pool. Default value: true`.

ldap

Warning

The following settings MUST be in the config file for LDAP authentication to Active Directory to work:

  • base_dn
  • bind_dn
  • group_dn
  • host

If those settings are missing, you will get authentication errors and be unable to proceed.

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 Infra 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 Infra 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'

Note

If you need to escape characters in a distinguished name, such as when using Active Directory, they must be escaped with a backslash escape character.

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

Default value: nil.

ldap['bind_password']

Legacy configuration for the password of 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. As of Chef Server 12.14, this is no longer the preferred command.

Please use chef-server-ctl set-secret ldap bind_password from the Secrets Management commands.

chef-server-ctl set-secret ldap bind_password
Enter ldap bind_password:    (no terminal output)
Re-enter ldap bind_password: (no terminal output)

Remove a set password via

chef-server-ctl remove-secret ldap bind_password
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=abcxyz,OU=users,DC=company,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 Infra 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 Infra 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 Infra Server to connect to the LDAP server using SSL. Default value: false. Must be false when ldap['tls_enabled'] is true.

Note

It’s recommended that you enable SSL for Active Directory.

Note

Previous versions of the Chef Infra 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 Infra 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 Infra 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 Infra 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.
