shellvar: type/provider for shell files for Puppet

This module provides a new type/provider for Puppet to read and modify shell config files using the Augeas configuration library.

The advantage of using Augeas over the default Puppet parsedfile implementations is that Augeas will go to great lengths to preserve file formatting and comments, while also failing safely when needed.

This provider will hide all of the Augeas commands etc., you don't need to know anything about Augeas to make use of it.

Requirements

Ensure both Augeas and ruby-augeas 0.3.0+ bindings are installed and working as normal.

See Puppet/Augeas pre-requisites.

Installing

The module can be installed easily (documentation):

puppet module install herculesteam/augeasproviders_shellvar

Documentation and examples

Type documentation can be generated with puppet doc -r type or viewed on the Puppet Forge page.

manage simple entry

shellvar { "HOSTNAME":
  ensure => present,
  target => "/etc/sysconfig/network",
  value  => "host.example.com",
}

shellvar { "disable rsyncd":
  ensure   => present,
  target   => "/etc/default/rsync",
  variable => "RSYNC_ENABLE",
  value    => "false",
}

shellvar { "ntpd options":
  ensure   => present,
  target   => "/etc/sysconfig/ntpd",
  variable => "OPTIONS",
  value    => "-g -x -c /etc/myntp.conf",
}

manage entry with comment

shellvar { "HOSTNAME":
  ensure  => present,
  target  => "/etc/sysconfig/network",
  comment => "My server's hostname",
  value   => "host.example.com",
}

export values

shellvar { "HOSTNAME":
  ensure  => exported,
  target  => "/etc/sysconfig/network",
  value   => "host.example.com",
}

unset values

shellvar { "HOSTNAME":
  ensure  => unset,
  target  => "/etc/sysconfig/network",
}

force quoting style

Values needing quotes will automatically get them, but they can also be explicitly enabled. Unfortunately the provider doesn't help with quoting the values themselves.

shellvar { "RSYNC_IONICE":
  ensure   => present,
  target   => "/etc/default/rsync",
  value    => "-c3",
  quoted   => "single",
}

delete entry

shellvar { "RSYNC_IONICE":
  ensure => absent,
  target => "/etc/default/rsync",
}

remove comment from entry

shellvar { "HOSTNAME":
  ensure  => present,
  target  => "/etc/sysconfig/network",
  comment => "",
}

replace commented value with entry

shellvar { "HOSTNAME":
  ensure    => present,
  target    => "/etc/sysconfig/network",
  value     => "host.example.com",
  uncomment => true,
}

uncomment a value

shellvar { "HOSTNAME":
  ensure    => present,
  target    => "/etc/sysconfig/network",
  uncomment => true,
}

array values

You can pass array values to the type.

There are two ways of rendering array values, and the behavior is set using the array_type parameter. array_type takes three possible values:

  • auto (default): detects the type of the existing variable, defaults to string;
  • string: renders the array as a string, with a space as element separator;
  • array: renders the array as a shell array.

For example:

shellvar { "PORTS":
  ensure     => present,
  target     => "/etc/default/puppetmaster",
  value      => ["18140", "18141", "18142"],
  array_type => "auto",
}

will create PORTS="18140 18141 18142" by default, and will change PORTS=(123) to PORTS=("18140" "18141" "18142").

shellvar { "PORTS":
  ensure     => present,
  target     => "/etc/default/puppetmaster",
  value      => ["18140", "18141", "18142"],
  array_type => "string",
}

will create PORTS="18140 18141 18142" by default, and will change PORTS=(123) to PORTS="18140 18141 18142".

shellvar { "PORTS":
  ensure     => present,
  target     => "/etc/default/puppetmaster",
  value      => ["18140", "18141", "18142"],
  array_type => "array",
}

will create PORTS=("18140" "18141" "18142") by default, and will change PORTS=123 to PORTS=(18140 18141 18142).

Quoting is honored for arrays:

  • When using the string behavior, quoting is global to the string;
  • When using the array behavior, each value in the array is quoted as requested.

appending to arrays

shellvar { "GRUB_CMDLINE_LINUX":
  ensure       => present,
  target       => "/etc/default/grub",
  value        => "cgroup_enable=memory",
  array_append => true,
}

will change GRUB_CMDLINE_LINUX="quiet splash" to GRUB_CMDLINE_LINUX="quiet splash cgroup_enable=memory".

shellvar { "GRUB_CMDLINE_LINUX":
  ensure       => present,
  target       => "/etc/default/grub",
  value        => ["quiet", "cgroup_enable=memory"],
  array_append => true,
}

will also change GRUB_CMDLINE_LINUX="quiet splash" to GRUB_CMDLINE_LINUX="quiet splash cgroup_enable=memory".

removing from arrays

shellvar { "GRUB_CMDLINE_LINUX":
  ensure       => absent,
  target       => "/etc/default/grub",
  value        => "cgroup_enable=memory",
  array_append => true,
}

will change GRUB_CMDLINE_LINUX="quiet splash cgroup_enable=memory" to GRUB_CMDLINE_LINUX="quiet splash".

shellvar { "GRUB_CMDLINE_LINUX":
  ensure       => absent,
  target       => "/etc/default/grub",
  value        => ["quiet", "cgroup_enable=memory"],
  array_append => true,
}

will also change GRUB_CMDLINE_LINUX="splash cgroup_enable=memory" to GRUB_CMDLINE_LINUX="splash".
