sysctl: type/provider for sysctl for Puppet
This module provides a new type/provider for Puppet to read and modify sysctl 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
On Puppet 2.7.14+, the module can be installed easily (documentation):
puppet module install herculesteam/augeasproviders_sysctl
You may see an error similar to this on Puppet 2.x (#13858):
Error 400 on SERVER: Puppet::Parser::AST::Resource failed with error ArgumentError: Invalid resource type `sysctl` at ...
Ensure the module is present in your puppetmaster's own environment (it doesn't
have to use it) and that the master has pluginsync enabled. Run the agent on
the puppetmaster to cause the custom types to be synced to its local libdir
(puppet master --configprint libdir
) and then restart the puppetmaster so it
loads them.

manage simple entry
sysctl { "net.ipv4.ip_forward":
ensure => present,
value => "1",
}
manage entry with comment
sysctl { "net.ipv4.ip_forward":
ensure => present,
value => "1",
comment => "test",
}
delete entry
sysctl { "kernel.sysrq":
ensure => absent,
}
remove comment from entry
sysctl { "kernel.sysrq":
ensure => present,
comment => "",
}
manage entry in another sysctl.conf location
sysctl { "net.ipv4.ip_forward":
ensure => present,
value => "1",
target => "/etc/sysctl.d/forwarding.conf",
}
do not update value with the sysctl
command
sysctl { "net.ipv4.ip_forward":
ensure => present,
value => "1",
apply => false,
}
only update the value with the sysctl
command, do not persist to disk
sysctl { "net.ipv4.ip_forward":
ensure => present,
value => "1",
persist => false,
}
ignore the application of a yet to be activated sysctl value
sysctl { "net.ipv6.conf.all.autoconf":
ensure => present,
value => "1",
silent => true
}
