Recipes

default

Installs the varnish package, manages the default varnish configuration file, and the init script defaults file.

repo

If placed before the default recipe in the run list, the official Varnish project apt repository will offer access to more version and platform support.

Usage

On systems that need a high performance caching server, use recipe[varnish]. Additional configuration can be done by modifying the default.vcl.erb and default.erb templates.

If running on a Redhat derivative then you may need to include yum-epel as it provides the jemalloc dependency that varnish needs

Resources

See the distro_install and vendor_install recipes for examples of these resources in action.

varnish_install

Installs Varnish with the default configuration supplied by the package.

The :install action handles package installation. By default, it will install Varnish from your distro repositories. If you set the vendor_repo parameter to true, then it will install Varnish from the varnish-cache repositories.

Parameters

Name Type Default Value
package_name string 'varnish'
vendor_repo true or false false
vendor_version string '4.0'

Actions

  • :install - Installs and enables the Varnish service.

varnish_default_config

Configures the Varnish service. If you do not include this, the config files that come with your distro package will be used instead.

Name Type Default Value
start_on_boot true or false true
max_open_files integer 131_072
max_locked_memory integer 82_000
instance_name string nil
listen_address string nil
listen_port integer 6081
admin_listen_address string '127.0.0.1'
admin_plisten_port integer 6082
user string 'varnish'
group string 'varnish'
ttl integer 120
storage 'malloc' or 'file' 'file'
file_storage_path string nil
file_storage_size string '1G'
malloc_size string nil
path_to_secret string '/etc/varnish/secret'

You can also send a hash to parameters which will add additional parameters to the varnish daemon via the -p option. The default hash is:

{ 'thread_pools' => '4',
  'thread_pool_min' => '5',
  'thread_pool_max' => '500',
  'thread_pool_timeout' => '300' }

Actions

  • :configure - Creates the varnish configuration file from template.

varnish_default_vcl

Name Type Default Value
backend_host string 'localhost'
backend_port integer 8080

Actions

  • :configure - Creates a default.vcl file.

varnish_log

Configures varnishlog or varnishncsa service. You can define both logfiles by calling varnish_log more than once. You can install logrotate config files if you wish as well.

Name Type Default Value
file_name string '/var/log/varnish/varnishlog.log'
pid string '/var/run/varnishlog.pid'
log_format 'varnishlog' or 'varnishncsa' 'varnishlog'
ncsa_format_string string `'%h
instance_name string nil
logrotate true or false true
logrotate_path string '/etc/logrotate.d'

Actions

  • :configure - configures the varnishlog or varnishncsa service.
