Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the supermarket mailing list.

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.

Examples

Install from the OS distribution :

varnish_install 'default' do
  package_name 'varnish'
  vendor_repo false
end

Install version 4 from the vendor :

varnish_install 'default' do
  package_name 'varnish'
  vendor_repo true
  vendor_version '4.0'
end

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 '/var/lib/varnish/%s_storage.bin' where %s is replaced with the resource name
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.

Example

Configure some parameters on the Varnish service :

varnish_default_config 'default' do
  start_on_boot true
  max_open_files 131_072
  max_locked_memory 82_000
  listen_address nil
  listen_port 6081
  path_to_vcl '/etc/varnish/default.vcl'
  admin_listen_address '127.0.0.1'
  admin_listen_port 6082
  user 'varnish'
  group 'varnish'
  ttl 120
  storage 'malloc'
  malloc_size "#{(node['memory']['total'][0..-3].to_i * 0.75).to_i}K"
  parameters(thread_pools: '4',
             thread_pool_min: '5',
             thread_pool_max: '500',
             thread_pool_timeout: '300')
  path_to_secret '/etc/varnish/secret'
end

varnish_default_vcl

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

Example

Set a backend to example.com:80 :

varnish_default_vcl 'default' do
  backend_host 'example.com'
  backend_port 80
end

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.

Examples

Configure varnish logs with log rotation :

varnish_log 'default' do
  file_name '/var/log/varnish/varnishlog.log'
  pid '/var/run/varnishlog.pid'
  log_format 'varnishlog'
  logrotate true
  logrotate_path '/etc/logrotate.d'
end

Configure ncsa logs with a specific output format and without log rotation :

varnish_log 'default_ncsa' do
  file_name '/var/log/varnish/varnishncsa.log'
  pid '/var/run/varnishncsa.pid'
  log_format 'varnishncsa'
  ncsa_format_string '%h|%l|%u|%t|\"%r\"|%s|%b|\"%{Referer}i\"|\"%{User-agent}i\"'
  logrotate false
end

varnish Cookbook CHANGELOG

This file is used to list changes made in each version of the varnish cookbook.

v2.2.2

  • #86 - Removed monkey patching of service providers

v2.2.1

  • Fix a bug in the monkey patched service resource, so that the changes needed for Varnish don't affect other services. #83.
  • Update docs, Rakefile, standards. #79.
  • Add additional examples to the documentation. #74.

v2.2.0

  • Fix default storage bug. Specify a default file storage location, as one is required with file backend, fixes #72. Adjust template for default configuration of varnish so that it won't do the file backend without a path, since that's illegal syntax.

  • Cause varnish reload to happen after restart. Delayed notifications are queued up in order. In this case, it makes sense for the reload to happen after the restart.

  • Switch from service restart to service reload. The varnish_default_vcl has been updated to perform a service reload instead of a service restart. This will prevent the cache from being cleared when a reload of the vcl file is enough.

v2.1.1

  • Fixes #56. The apt resource may not be included, so no need to run a notification on it.

v1.2.0

  • Make resource_name compatible with older Chef. Switch from passing an argument into resource_name to using the assignment operator '='. This will make resource_name compatible with older versions of Chef.

v1.1.0 (2015-02-16)

  • Created libraries, to eventually replace recipe functionality, currently can be used along side recipes
  • Added CircleCI support for automated testing
  • Added logrotate support
  • Added varnish(log|nsca) support
