Systemd Chef Cookbook

Cookbook Build Status

A resource-driven Chef cookbook for managing GNU/Linux systems via systemd.

Table of Contents

Recommended Reading

Usage Tips

Drop Ins

Systemd provides support for "drop-in" units that work really well for config- mgmt systems; rather than taking over an entire unit definition, you can apply custom configuration (e.g. resource limits) that will be merged into the vendor- provided unit. It's recommended to use these when modifying units installed via the package manager. See drop-in docs for more info.

Daemon Reloads

By default, changes to unit resources will be applied to the system immediately via calls to systemctl daemon-reload. However, on systems with large numbers of units, daemon-reload can be problematic. For users encountering problems (hangs, slowness) with systemctl daemon-reload calls, this cookbook allows users to disable daemon-reloads by setting the auto_reload attribute to false.

In some cases, it may be possible to avoid daemon-reload entirely by using the set_properties action. However, only a subset of unit properties are supported by systemctl set-property, so, unfortunately, in some cases a daemon-reload may be unavoidable. For these cases, it's possible run a daemon-reload once at the end of a converge.

This cookbook provides the daemon_reload recipe to help with this. It removes the need to have every resource send a notification, and triggers a reload at the end of a converge if any auto_reload false units have been updated.

Attributes

too many to describe in detail ;). in general, the attributes correspond to the related resource attributes.

Resources

Unit Resources

All unit resources support the following actions:

Action Description
:create render unit configuration file from attributes
:delete delete unit configuration file
:enable enable the unit at boot, unless static (lacks Install section)
:disable disables the unit at boot, unless static
:start starts the unit
:stop stops the unit
:restart restarts the unit
:reload reloads the unit
:set_properties runs systemctl --runtime set-property for unit configuration

Important: The notable exception is when the unit is a drop-in unit, in which case it supports only the :create, :delete, and :set_properties actions.

systemd_automount

Unit which describes a file system automount point controlled by systemd. Documentation

Example usage (always paired with a mount unit):

systemd_mount 'proc-sys-fs-binfmt_misc' do
  description 'Arbitrary Executable File Formats File System'
  default_dependencies false
  mount do
    what 'binfmt_misc'
    where '/proc/sys/fs/binfmt_misc'
    type 'binfmt_misc'
  end
end

systemd_automount 'proc-sys-fs-binfmt_misc' do
  description 'Arbitrary Executable File Formats File System Automount Point'
  default_dependencies false
  before 'sysinit.target'
  condition_path_exists '/proc/sys/fs/binfmt_misc/'
  condition_path_is_read_write '/proc/sys/'
  automount do
    where '/proc/sys/fs/binfmt_misc'
  end
end
Attribute Description Default
where see docs nil
directory_mode see docs nil
timeout_idle_sec see docs nil

Also supports:

--

systemd_mount

Unit which describes a file system mount point controlled by systemd. Documentation

Example usage:

systemd_mount 'tmp' do
  description 'Temporary Directory'
  condition_path_is_symbolic_link '!/tmp'
  default_dependencies false
  conflicts 'umount.target'
  before %w( local-fs.target umount.target )
  mount do
    what 'tmpfs'
    where '/tmp'
    type 'tmpfs'
    options 'mode=1777,strictatime,noexec,nosuid'
  end

systemd_path

Unit which describes information about a path monitored by systemd for path-based activities. Documentation

Example usage (showing cups service activation when work is available):

systemd_path 'cups' do
  description 'CUPS Scheduler'
  install do
    wanted_by 'multi-user.target'
  end
  path do
    path_exists_glob '/var/spool/cups/d*'
  end
  action [:create, :enable, :start]
end

Also supports:

--

systemd_service

Unit which describes information about a process controlled and supervised by systemd. Documentation.

While there is some overlap with the service resource in Chef-core, this resource is more narrowly focused on service unit config/management on systemd-based platforms, whereas the Chef-core service resource works across multiple service-management frameworks.

As such, while it is possible to perform lifecycle management of services on systemd platforms using the systemd_service resource, the systemd cookbook authors do not recommend doing so. Instead, it is recommended to pair systemd_service instances with platform-agnostic service resources, as demonstrated below.

Example usage:

cookbook_file '/etc/init/httpd.conf' do
  source 'httpd.conf'
  only_if { ::File.executable?('/sbin/initctl') } # Upstart
end

systemd_service 'httpd' do
  description 'Apache HTTP Server'
  after %w( network.target remote-fs.target nss-lookup.target )
  install do
    wanted_by 'multi-user.target'
  end
  service do
    environment 'LANG' => 'C'
    exec_start '/usr/sbin/httpd $OPTIONS -DFOREGROUND'
    exec_reload '/usr/sbin/httpd $OPTIONS -k graceful'
    kill_signal 'SIGWINCH'
    kill_mode 'mixed'
    private_tmp true
  end
  only_if { ::File.open('/proc/1/comm').gets.chomp == 'systemd' } # systemd
end

service 'httpd' do
  action [:enable, :start]
end

Common Resource Attributes

Organization

special no-op attributes that yield a block for the purpose of being able to group attributes of a resource similar to their rendered grouping.

Attribute Description Default
install no-op block yielder nil
$unit_type no-op block yielder nil

By way of explanation:

systemd_automount 'vagrant-home' do
  description 'Test Automount'
  install do
    wanted_by 'local-fs.target'
  end
  automount do
    where '/home/vagrant'
  end
end

is the same as...

systemd_automount 'vagrant-home' do
  description 'Test Automount'
  wanted_by 'local-fs.target'
  where '/home/vagrant'
end
