varnish Cookbook

Cookbook Version Build Status OpenCollective OpenCollective License

Configures varnish.

Maintainers

This cookbook is maintained by the Sous Chefs. The Sous Chefs are a community of Chef cookbook maintainers working together to maintain important cookbooks. If you’d like to know more please visit sous-chefs.org or come chat with us on the Chef Community Slack in #sous-chefs.

Requirements

chef-client

Platforms

Other operating systems and Varnish versions may work, but are not explicitly tested or supported.

Global Attributes

These attributes used as defaults for both resources and the varnish::configure cookbook but can be also overridden with other attributes and resource properties described later.

Recipes

default

This is not used currently but reserved for minimal configuration needed for all the resources/recipes to work correctly.

configure

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

Usage

You can either use include the varnish::configure recipe and configure the setup using the recipe attributes described below or use the resources directly.

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

Configure Recipe Attributes

Common Settings

The configure recipe uses the resources below to get varnish and varnishlog installed and running from the vendor repo. The recipe will work without any additional configuration however there is a few common attributes that you may want to set.

If you are using the default vcl_template then backend_port and backend_host are configurable through these parameters.

Any resource property in the varnish::configure recipe can be configured. The keys under the namespace's listed below will map to the property name. Refer to the resource documentation for details on all the properties.

Resource Attribute Namespace
varnish_repo 'configure' node['varnish']['configure']['repo']
package 'varnish' node['varnish']['configure']['package']
service 'varnish' node['varnish']['configure']['service']
varnish_config 'default' node['varnish']['configure']['config']
vcl_template 'default' node['varnish']['configure']['vcl_template']
varnish_log 'default' node['varnish']['configure']['log']
varnish_log 'ncsa' node['varnish']['configure']['ncsa']

Recipe Example's

Use the systems varnish package and skip enabling the varnishlog daemon :

node.override['varnish']['configure']['repo']['action'] = :nothing
node.override['varnish']['configure']['log']['action'] = :nothing

include_recipe 'varnish::configure'

Use custom.vcl.erb template in my_cookbook and configure varnish to listen on port 80:

node.override['varnish']['configure']['config']['listen_port'] = 80
node.override['varnish']['configure']['vcl_template']['source'] = 'custom.vcl.erb'
node.override['varnish']['configure']['vcl_template']['cookbook'] = 'my_cookbook'

include_recipe 'varnish::configure'

Resources

The following resources are provided:

Resource Recipe Example

Install and configure varnish 6.6 using vcl config default.vcl in the current cookbook as well as a backend.vcl template.

include_recipe 'varnish::default'

varnish_repo 'configure' do
  major_version 6.6
end

package 'varnish'

service 'varnish' do
  action [:enable, :start]
end

varnish_config 'default' do
  listen_address '0.0.0.0'
  listen_port 80
  storage 'malloc'
  malloc_percent 33
end

vcl_template 'backends.vcl' do
  source 'backends.vcl.erb'
  variables(
      backends_ids: Array(1..16),
      env: 'live',
  )
end

vcl_file 'default.vcl'

# varnishlog
