Overview
This module Installs and configures Varnish.
Puppet 3 Support
Please note that the master branch of this module does not support Puppet 3!
On 31st December 2016, support for Puppet 3.x was withdrawn. As such, this module no longer supports Puppet 3 - if you require Puppet 3 compatibility, please use the latest version 4.x version from the Puppet Forge, or the puppet3 branch in Git.
Module Description
This module Supports Varnish versions 3.0, 4.0, 4.1, 5.0, 5.1, 5.2, 6.0, 6.1 across Ubuntu 14.04/16.04/18.04, Debian 7/8/9 and RedHat derivates 6/7.
This module will install Varnish, by default version 4.1 from the official Packagecloud repositories, adding EPEL for RedHat-like systems and working around a SELinux policy bug in RHEL/CentOS 6 for Varnish 4.0 and above.
It will also install and configure a Systemd service for certain OS/Varnish combinations.
If necessary, you can specify any of the Varnish versions above, although there are imcompatibilities with some versions of Varnish and some OS versions, see Limitations.
Setup
To accept all default parameters - at minimum it is suggested you set a
secret (if not explicitly set, one will be created via
/proc/sys/kernel/random/uuid
) and overwrite the packaged default.vcl
.
class { '::varnish':
secret => '6565bd1c-b6d1-4ba3-99bc-3c7a41ffd94f',
}
::varnish::vcl { '/etc/varnish/default.vcl':
content => template('data/varnish/default.vcl.erb'),
}
Multiple Listen Interfaces
Varnish supports listening on multiple interfaces. The module implements this
by exposing a listen
parameter, which can either be set to a String value for
one interface (e.g. 127.0.0.1
or 0.0.0.0
), or an array of values.
By default, the module will append listen_port
to each element of the
array - however to set a different port for each interface, just append it
using standard notation, for example: 127.0.0.1:8080
.
Usage
Examples
To use a static file with varnish::vcl
rather than a template:
::varnish::vcl { '/etc/varnish/default.vcl':
content => file('data/varnish/default.vcl'),
# Equivalent to: source => 'puppet:///modules/data/varnish/default.vcl'
}
To pin Varnish to a specific version - you may also provide varnish_version
as long as it matches the major and minor version in package_ensure
, however
the module will automatically calculate varnish_version
if not set:
class { '::varnish':
package_ensure => '4.0.5-1~xenial',
}
To configure Varnish to listen on port 8080 on localhost and port 6081 on
172.16.100.10
:
class { '::varnish':
listen => ['127.0.0.1:8080','172.16.100.10:6081'],
}
To configure Varnish to listen on port 80, specifically on localhost and
192.168.1.195
:
class { '::varnish':
listen => ['127.0.0.1','192.168.1.195'],
listen_port => '80',
}
To use multiple storage backends in varnish for example a primary 4GB memory backend
and a 50GB file backend
:
class { '::varnish':
storage_type => 'malloc',
storage_size => '4G',
storage_additional => [
'file,/var/lib/varnish/varnish_additional.bin,50G',
]
}
