Chef Client Cookbook

This cookbook is used to configure a system to run the Chef Infra Client.

Deprecation

This cookbook is no longer under active maintenance. The functionality previously provided here is now built into Chef Infra Client itself making it easier to configure Chef Infra Client without the need for external dependencies.

See these built-in resources for managing client.rb configuration and setting up Chef Infra Client to run on a schedule:

• chef_client_config
• chef_handler
• chef_client_trusted_certificate
• chef_client_cron
• chef_client_systemd_timer
• chef_client_scheduled_task
• chef_client_launchd

What about older Chef Infra Client Releases

If you're using an Infra Client release before the above resources shipped, you can keep using this cookbook without issue. Just keep in mind that at some point in the future changes to Chef Infra Client may cause this cookbook to stop working. We believe the built-in resoures offer a more powerful configuration options for users. The approach offered by these resources also align with our own best practices and we'd highly suggest moving towards those resources for configuring your Chef Infra Client.

The new resources are missing x, y, or z

If there's af feature missing from the new resources please do let us know at https://github.com/chef/chef/issues. We will not be replicating all functionality of this cookbook, but we are interested in hearing what the community needs to manage their systems.

Resources

The chef-client cookbook provides several resources for setting up Chef Infra Client to run on a schedule. When possible these resources should be used instead of the legacy attributes / recipes as these same resources will be included in Chef Infra Client 16+ out of the box.

chef_client_scheduled_task

The chef_client_scheduled_task resource setups up Chef Infra Client to run as a scheduled task on Windows. You can use this resource directly in any of your own recipes. Using this resource to configure Chef Infra Client running as a scheduled task allows you to control where you store the user credentials instead of storing them as node attributes. This is useful if you want to store these credentials in an encrypted databag or other secrets store.

Actions

• :add
• :remove

Properties

• user - The username to run the task as. default: 'System'
• password The password of the user to run the task as if not using the System user
• frequency - Frequency with which to run the task (e.g., 'hourly', 'daily', etc.) Default is 'minute'
• frequency_modifier Numeric value to go with the scheduled task frequency - default: '30'
• start_time The start time for the task in HH:mm format (ex: 14:00). If the frequency is minute default start time will be Time.now plus the frequency_modifier number of minutes.
• start_date - The start date for the task in m:d:Y format (ex: 12/17/2017). nil by default and isn't necessary if you're running a regular interval.
• splay - A random number of seconds between 0 and X to add to interval. default: '300'
• config_directory - The path to the Chef config directory. default: 'C:/chef'
• log_file_name - The name of the log file. default: 'client.log'
• log_directory - The path to the Chef log directory. default: 'CONFIG_DIRECTORY/log'
• chef_binary_path - The path to the chef-client binary. default: 'C:/opscode/chef/bin/chef-client'
• daemon_options - An optional array of extra options to pass to the chef-client
• task_name - The name of the scheduled task. This allows for multiple chef_client_scheduled_task resources when it is used directly like in a wrapper cookbook. default: 'chef-client'

chef_client_cron

The chef_client_cron resource sets up Chef Infra Client to run as a cron job using a cron.d configuration file on Linux hosts or a job in /etc/crontab for other Unix operating systems. You can use this resource directly in any of your own recipes.

Actions

• :add
• :remove

Properties

• user - The username to run the task as. default: 'root'
• minute - The minute that Chef Infra Client will run as a cron task. default: '0,30' (every 30 minutes)
• hour - The hour that Chef Infra Client will run as a cron task. default: '*'
• day - The day that Chef Infra Client will run as a cron task. default: '*'
• month - The month that Chef Infra Client will run as a cron task. default: '*'
• weekday - The weekday that Chef Infra Client will run as a cron task. default: '*'
• comment - A comment to add to the cron file.
• mailto - The e-mail address to e-mail any cron task failures to.
• job_name - The name of the cron task to create. This allows you to have schedules with different options if necessary. default: 'chef-client'
• splay - A random number of seconds between 0 and X to add to interval. default: '300'
• environment - A hash of environment variables to pass to chef-client's execution (e.g. SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt chef-client)
• config_directory - The path to the Chef config directory. default: '/etc/chef/'
• log_file_name - The name of the log file. default: 'client.log'
• log_directory - The path to the Chef log directory. default: '/var/log/chef' on *nix or '/Library/Logs/Chef' on macOS
• append_log_file - Whether to append to the log. Default: true chef-client output.
• chef_binary_path - The path to the chef-client binary. default: '/opt/chef/bin/chef-client'
• daemon_options - An optional array of extra command line options to pass to the chef-client

chef_client_trusted_certificate

The chef_client_trusted_certificate allows you to add a certificate to Chef Infra Client's set of trusted certificates. This is helpful when adding internal certificates for systems that the Chef Infra Client will later need to communicate with using SSL. You can use this resource directly in any of your own recipes.

Actions

• :add
• :remove

Properties

• cert_name - The name on disk for the cert file. If not specified the resource name will be used (and .pem appended if necessary)
• certificate - The text content of the certificate file

Examples

Attributes

The following attributes affect the behavior of the chef-client program when running as a service through one of the service recipes, or in cron with the cron recipe, or are used in the recipes for various settings that require flexibility.

• node['chef_client']['interval'] - Sets Chef::Config[:interval] via command-line option for number of seconds between chef-client daemon runs. Default 1800.
• node['chef_client']['splay'] - Sets Chef::Config[:splay] via command-line option for a random amount of seconds to add to interval. On windows, this value is used for the scheduled task's random delay. Default 300.
• node['chef_client']['log_file'] - Sets the file name used to store chef-client logs. Default "client.log".
• node['chef_client']['log_dir'] - Sets directory used to store chef-client logs. Default "/var/log/chef".
• node['chef_client']['log_rotation']['options'] - Set options to logrotation of chef-client log file. Default ['compress'].
• node['chef_client']['log_rotation']['prerotate'] - Set prerotate action for chef-client logrotation. Default to nil.
• node['chef_client']['log_rotation']['postrotate'] - Set postrotate action for chef-client logrotation. Default to chef-client service reload depending on init system. It should be empty to skip reloading chef-client service in case if node['chef_client']['systemd']['timer'] is true.
• node['chef_client']['conf_dir'] - Sets directory used via command-line option to a location where chef-client search for the client config file . Default "/etc/chef".
• node['chef_client']['bin'] - Sets the full path to the chef-client binary. Mainly used to set a specific path if multiple versions of chef-client exist on a system or the bin has been installed in a non-sane path. Default "/opt/chef/bin/chef-client".
• node['chef_client']['ca_cert_path'] - Sets the full path to the PEM-encoded certificate trust store used by chef-client when daemonized. If not set, default values are used.
• node['chef_client']['cron']['minute'] - The minute that chef-client will run as a cron task. See cron recipe
• node['chef_client']['cron']['hour'] - The hour that chef-client will run as a cron task. See cron recipe
• node['chef_client']['cron']['weekday'] - The weekday that chef-client will run as a cron task. See cron recipe
• node['chef_client']['cron']['environment_variables'] - Environment variables to pass to chef-client's execution (e.g. SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt chef-client)
• node['chef_client']['cron']['log_file'] - Location to capture the log output of chef-client during the chef run.
• node['chef_client']['cron']['append_log'] - Whether to append to the log. Default: false chef-client output.
• node['chef_client']['cron']['use_cron_d'] - If true, use the cron_d resource. If false (default), use the cron resource built-in to Chef.
• node['chef_client']['cron']['mailto'] - If set, MAILTO env variable is set for cron definition
• node['chef_client']['cron']['priority'] - If set, defines the scheduling priority for the chef-client process. MUST be a value between -20 and 19. ONLY applies to *nix-style operating systems.
• node['chef_client']['reload_config'] - If true, reload Chef config of current Chef run when client.rb template changes (defaults to true)
• node['chef_client']['daemon_options'] - An array of additional options to pass to the chef-client service, empty by default, and must be an array if specified.
• node['chef_client']['systemd']['timer'] - If true, uses systemd timer to run chef frequently instead of chef-client daemon mode (defaults to false). This only works on platforms where systemd is installed and used.
• node['chef_client']['systemd']['timeout'] - If configured, sets the systemd timeout. This might be useful to avoid stalled chef runs in the systemd timer setup.
• node['chef_client']['systemd']['restart'] - The string to use for systemd Restart= value when not running as a timer. Defaults to always. Other possible options: no, on-success, on-failure, on-abnormal, on-watchdog, on-abort.
• node['chef_client']['systemd']['killmode'] - If configured, the string to use for the systemd KillMode= value. This determines how PIDs spawned by the chef-client process are handled when chef-client PID stops. Options: control-group, process, mixed, none. Systemd defaults to control-group when this is not specified. More information can be found on the systemd.kill man page.
• node['chef_client']['task']['frequency'] - Frequency with which to run the chef-client scheduled task (e.g., 'hourly', 'daily', etc.) Default is 'minute'.
• node['chef_client']['task']['frequency_modifier'] - Numeric value to go with the scheduled task frequency. Default is node['chef_client']['interval'].to_i / 60
• node['chef_client']['task']['start_time'] - The start time for the task in HH:mm format (ex: 14:00). If the frequency is minute default start time will be Time.now plus the frequency_modifier number of minutes.
• node['chef_client']['task']['start_date'] - The start date for the task in m:d:Y format (ex: 12/17/2017). nil by default and isn't necessary if you're running a regular interval.
• node['chef_client']['task']['user'] - The user the scheduled task will run as, defaults to 'SYSTEM'.
• node['chef_client']['task']['password'] - The password for the user the scheduled task will run as, defaults to nil because the default user, 'SYSTEM', does not need a password.
• node['chef_client']['task']['name'] - The name of the scheduled task, defaults to chef-client.

The following attributes are set on a per-platform basis, see the attributes/default.rb file for default values.

• node['chef_client']['init_style'] - Sets up the client service based on the style of init system to use. Default is based on platform and falls back to 'none'. See service recipes.

• node['chef_client']['run_path'] - Directory location where chef-client should write the PID file. Default based on platform, falls back to "/var/run".

• node['chef_client']['file_cache_path'] - Directory location for Chef::Config[:file_cache_path] where chef-client will cache various files. Default is unset as it causes problems on first chef runs. The default location is typically "/var/cache/cache" but could be different based on the platform. Use this attribute at your own risk.

• node['chef_client']['file_backup_path'] - Directory location for Chef::Config[:file_backup_path] where chef-client will backup templates and cookbook files. Default is based on platform, falls back to "/var/chef/backup".

• node['chef_client']['file_staging_uses_destdir'] - How file staging (via temporary files) is done. When true, temporary files are created in the directory in which files will reside. When false, temporary files are created under ENV['TMP']. When set to :auto it creates them in the destination directory, and falls back to the ENV['TMP'] directory when that is not possible. default value: chef-client default. This cookbook makes use of attribute-driven configuration with this attribute. See USAGE for examples.

• node['chef_client']['launchd_mode'] - (only for macOS) If set to 'daemon', runs chef-client with -d and -s options; defaults to 'interval'.

• node['chef_client']['launchd_working_dir'] - (only for macOS) Sets the working directory for the launchd user (generally root); defaults to /var/root.

• node['chef_client']['launchd_self-update'] - (only for macOS) Determines whether chef-client should attempt to :restart itself when changes are made to the launchd plist during converge. Note that the current implementation of macosx_service :restart unloads the daemon, which stops the current chef-client run and requires an external process to resume the service. Defaults to false.

• When chef_client['log_file'] is set and running on a logrotate supported platform (debian, rhel, fedora family), use the following attributes to tune log rotation.

  • node['chef_client']['logrotate']['rotate'] - Number of rotated logs to keep on disk, default 12.
  • node['chef_client']['logrotate']['frequency'] - How often to rotate chef client logs, default weekly.

• node['chef_client']['config'] - A hash of Chef::Config keys and their values, rendered dynamically in /etc/chef/client.rb.

• node['chef_client']['load_gems'] - Hash of gems to load into chef via the client.rb file

• node['ohai']['disabled_plugins'] - An array of ohai plugins to disable, empty by default, and must be an array if specified. Ohai 6 plugins should be specified as a string (ie. "dmi"). Ohai 7+ plugins should be specified as a symbol within quotation marks (ie. ":Passwd").

• node['ohai']['optional_plugins'] - An array of optional ohai plugins to enable, empty by default, and must be an array if specified. Ohai 6 plugins should be specified as a string (ie. "dmi"). Ohai 7+ plugins should be specified as a symbol within quotation marks (ie. ":Passwd").

• node['ohai']['plugin_path'] - An additional path to load Ohai plugins from. Necessary if you use the ohai_plugin resource in the Ohai cookbook to install your own ohai plugins.

Chef Client Config

For the most current information about Chef Client configuration, read the documentation..

• node['chef_client']['chef_license'] - Set to 'accept' or 'accept-no-persist' to accept the license before upgrading to Chef 15.

• node['chef_client']['config']['chef_server_url'] - The URL for the Chef server.

• node['chef_client']['config']['validation_client_name'] - The name of the chef-validator key that is used by the chef-client to access the Chef server during the initial chef-client run.

• node['chef_client']['config']['verbose_logging'] - Set the log level. Options: true, nil, and false. When this is set to false, notifications about individual resources being processed are suppressed (and are output at the :info logging level). Setting this to false can be useful when a chef-client is run as a daemon. Default value: nil.

• node['chef_client']['config']['rubygems_url'] - The location to source rubygems. It can be set to a string or array of strings for URIs to set as rubygems sources. This allows individuals to setup an internal mirror of rubygems for "airgapped" environments. Default value: https://www.rubygems.org.

• See USAGE for how to set handlers with the config attribute.

Recipes

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

config

Sets up the /etc/chef/client.rb config file from a template and reloads the configuration for the current chef-client run.

See USAGE for more information on how the configuration is rendered with attributes.

service recipes

The chef-client::service recipe includes one of the chef-client::INIT_STYLE_service recipes based on the attribute, node['chef_client']['init_style']. The individual service recipes can be included directly, too. For example, to use the init scripts, on a node or role's run list:

recipe[chef-client::init_service]

Use this recipe on systems that should have a chef-client daemon running, such as when Knife bootstrap was used to install Chef on a new system.

• init - uses the init script included in this cookbook, supported on debian and redhat family distributions.
• launchd - sets up the service under launchd, supported on macOS
• bsd - prints a message about how to update BSD systems to enable the chef-client service.
• systemd - sets up the service under systemd. Supported on systemd based distros.

default

Includes the chef-client::service recipe by default on *nix platforms and the task recipe for Windows hosts.

delete_validation

Use this recipe to delete the validation certificate (default /etc/chef/validation.pem) when using a chef-client after the client has been validated and authorized to connect to the server.

cron

Use this recipe to run chef-client as a cron job rather than as a service. The cron job runs after random delay that is between 0 and 90 seconds to ensure that the chef-clients don't attempt to connect to the chef-server at the exact same time. You should set node['chef_client']['init_style'] = 'none' when you use this mode but it is not required.

task

Use this recipe to run chef-client on Windows nodes as a scheduled task. Without modifying attributes the scheduled task will run 30 minutes after the recipe runs, with each chef run rescheduling the run 30 minutes in the future. By default the job runs as the system user. The time period between runs can be modified with the default['chef_client']['task']['frequency_modifier'] attribute and the user can be changed with the default['chef_client']['task']['user'] and default['chef_client']['task']['password'] attributes.

Usage

Use the recipes as described above to configure your systems to run Chef as a service via cron / scheduled task or one of the service management systems supported by the recipes.

The chef-client::config recipe is only required with init style init (default setting for the attribute on debian/redhat family platforms, because the init script doesn't include the pid_file option which is set in the config.

If you wish to accept the Chef license before upgrading to Chef 15 you must use the chef-client::config recipe or set the chef_license value in your config manually. See Accepting the Chef license for more details or other ways to accept the license.

The config recipe is used to dynamically generate the /etc/chef/client.rb config file. The template walks all attributes in node['chef_client']['config'] and writes them out as key:value pairs. The key should be the configuration directive. For example, the following attributes (in a role):

default_attributes(
  "chef_client" => {
    "config" => {
      "ssl_verify_mode" => ":verify_peer",
      "client_fork" => true
    }
  }
)

will render the following configuration (/etc/chef/client.rb):

chef_server_url "https://api.chef.io/organizations/MYORG"
validation_client_name "MYORG-validator"
ssl_verify_mode :verify_peer
node_name "config-ubuntu-1204"
client_fork true

The chef_server_url, node_name and validation_client_name are set by default in the attributes file from Chef::Config. They are presumed to come from the knife bootstrap command when setting up a new node for Chef. To set the node name to the default value (the node['fqdn'] attribute), it can be set false. Be careful when setting this or the Server URL, as those values may already exist.

As another example, to set HTTP proxy configuration settings. By default Chef will not use a proxy.

default_attributes(
  "chef_client" => {
    "config" => {
      "http_proxy" => "http://proxy.mycorp.com:3128",
      "https_proxy" => "http://proxy.mycorp.com:3128",
      "http_proxy_user" => "my_username",
      "http_proxy_pass" => "Awe_some_Pass_Word!",
      "no_proxy" => "*.vmware.com,10.*"
    }
  }
)

Special Behavior

Because attributes are strings and the /etc/chef/client.rb can use settings that are not string, such as symbols, some configuration attributes have resulting lines with special behavior:

• the audit_mode, log_level, and ssl_verify_mode attributes are converted to symbols. The attribute need not include an initial colon. For example:

default_attributes(
  "chef_client" => {
    "config" => {
      "ssl_verify_mode" => ":verify_peer",
      "log_level" => "debug"
    }
  }
)

will render the following configuration (/etc/chef/client.rb):

ssl_verify_mode :verify_peer
log_level :debug

• the log_level setting can be either a string representing a file path or one of the symbols STDOUT, STDERR, :syslog, and :win_evt. If the log_level attribute is a string suggestive of one of these symbols, the resulting configuration line will use the symbol. For example,

default_attributes(
  "chef_client" => {
    "config" => {
      "log_location" => "STDOUT"
    }
  }
)

will render the following configuration (/etc/chef/client.rb):

log_location STDOUT

and

default_attributes(
  "chef_client" => {
    "config" => {
      "log_location" => ":syslog"
    }
  }
)

will render the following configuration (/etc/chef/client.rb):

log_location :syslog

The strings "syslog" and "win_evt" will become the symbols :syslog and :win_evt regardless of whether they have an initial colon.

Configuration Includes

The /etc/chef/client.rb file will include all the configuration files in /etc/chef/client.d/*.rb. To create custom configuration, simply render a file resource with file (and the content parameter), template, remote_file, or cookbook_file. For example, in your own cookbook that requires custom Chef client configuration, create the following cookbook_file resource:

chef_gem 'syslog-logger'

cookbook_file "/etc/chef/client.d/myconfig.rb" do
  source "myconfig.rb"
  mode '0644'
  notifies :create, "ruby_block[reload_client_config]"
end

include_recipe 'chef-client::config'

Then create files/default/myconfig.rb with the configuration content you want. For example, if you wish to create a configuration to log to syslog:

require 'syslog-logger'
require 'syslog'

Logger::Syslog.class_eval do
  attr_accessor :sync, :formatter
end

log_location Chef::Log::Syslog.new('chef-client', ::Syslog::LOG_DAEMON)

On Windows:

log_location Chef::Log::WinEvt.new

Requiring Gems

Use the load_gems attribute to install gems that need to be required in the client.rb. This attribute should be a hash. The gem will also be installed with chef_gem. For example, suppose we want to use a Chef Handler Gem, chef-handler-updated-resources, which is used in the next heading. Set the attributes, e.g., in a role:

default_attributes(
  "chef_client" => {
    "load_gems" => {
      "chef-handler-updated-resources" => {
        "require_name" => "chef/handler/updated_resources",
        "version" => "0.1"
      }
    }
  }
)

Each key in load_gems is the name of a gem. Each gem hash can have two keys, the require_name which is the string that will be require'd in /etc/chef/client.rb, and version which is the version of the gem to install. If the version is not specified, the latest version will be installed.

The above example will render the following in /etc/chef/client.rb:

["chef/handler/updated_resources"].each do |lib|
  begin
    require lib
  rescue LoadError
    Chef::Log.warn "Failed to load #{lib}. This should be resolved after a chef run."
  end
end

Start, Report, Exception Handlers

To dynamically render configuration for Start, Report, or Exception handlers, set the following attributes in the config attributes:

• start_handlers
• report_handlers
• exception_handlers

This is an alternative to using the chef_handler cookbook.

Each of these attributes must be an array of hashes. The hash has two keys, class (a string), and arguments (an array). For example, to use the report handler in the Requiring Gems section:

default_attributes(
  "chef_client" => {
    "config" => {
      "report_handlers" => [
        {"class" => "SimpleReport::UpdatedResources", "arguments" => []}
      ]
    }
  }
)

If the handler you're using has an initialize method that takes arguments, then pass each one as a member of the array. Otherwise, leave it blank as above.

This will render the following in /etc/chef/client.rb.

report_handlers << SimpleReport::UpdatedResources.new()

Launchd

On macOS and macOS Server, the default service implementation is "launchd".

Since launchd can run a service in interval mode, by default chef-client is not started in daemon mode like on Debian or Ubuntu. Keep this in mind when you look at your process list and check for a running chef process! If you wish to run chef-client in daemon mode, set attribute chef_client.launchd_mode to "daemon".

Installing and updating chef-client

This cookbook does not handle updating the chef-client, as that's out of the cookbook's current scope. To sensibly manage updates of the chef-client's install, we refer you to:

• chef_client_updater - Cookbook for keeping your install up-to-date
