varnish Cookbook
Configures varnish.
Requirements
chef-client
- Requires chef-client 12.15 and above.
Platforms
Tested on the platforms below with distro installs and upstream Varnish packaging versions 3.0, 4.0, 4.1, and 5 unless otherwise noted.
Varnish | 3.0 | 4.0 | 4.1 | 5 | distro |
---|---|---|---|---|---|
CentOS 6.8 | ✔ | ✔ | ✔ | ✔ | ✘ |

Ubuntu 14.04 | ✔ | ✔ | ✔ | ✔ | ✔ |
Ubuntu 16.04 | ✘ | ✔ | ✔ | ✔ | ✔ |
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.
-
node['varnish']['conf_path']
- location of thedefault
file that controls the varnish init script on Debian/Ubuntu systems. -
node['varnish']['reload_cmd']
- location of the varnish reload script used by the systemd config file. This is not used for initd currently. -
node['varnish']['conf_source']
- template file source to use for thedefault
varnish init config. -
node['varnish']['conf_cookbook']
- template cookbook source to use for thedefault
varnish init config. -
node['varnish']['major_version']
- the major version of varnish to install. Can be 3.0, 4.0, 4.1, 5 or 6.0 and default's to 4.1.
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 include varnish::default and 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.
-
node['varnish']['configure']['repo']['action']
- Affects the vendor repo resource. Can be set to:nothing
to skip and use the systems package otherwise the default is to:configure
it. -
node['varnish']['configure']['package']['version']
- Specific varnish version to pass to the package resource. Default is to install the latest available version for the currentnode['varnish']['major_version']
. -
node['varnish']['configure']['log']['action']
- Affects the varnish_log resource. Can be set to:nothing
to skip and not set up logging otherwise the default is to:configure
it. -
node['varnish']['configure']['config']['listen_port']
- Port number to listen on for requests to varnish. Defaults to 6081. -
node['varnish']['configure']['vcl_template']['source']
- Name for default vcl template. Defaults to default.vcl.erb. -
node['varnish']['configure']['vcl_template']['cookbook']
- Name of the cookbook for the default vcl template. Uses this varnish cookbook by default.
If you are using the default vcl_template then backend_port and backend_host are configurable through these parameters.
-
node['varnish']['configure']['vcl_template']['variables']['config']['backend_port']
- The default vcl_template backend port (default: 80). -
node['varnish']['configure']['vcl_template']['variables']['config']['backend_host']
- The default vcl_template backend_host (default: 127.0.0.1).
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.

varnish Cookbook CHANGELOG
This file is used to list changes made in each version of the varnish cookbook.
v4.0.1
- Adds support for Varnish 3 and 4.0 on CentOS 7
- Adds support for Varnish 4.0 and 4.1 on Ubuntu 1604
v4.0.0
- Adds support Varnish 6.0
- Allow systemd platforms to set instance names. PR #157 and #153
- Note: In some cases (instance_name is set when using systemd) this will change the varnish instance name.
- Escape ncsa_format_string for systemd. Fixes #137
- Don't set -n when instance_name is nil or empty on systemd
v3.5.0
- Removed ChefSpec matchers as these are autogenerated by recent releases of ChefSpec in ChefDK
- Allow all platform families to set instance name in varnishlog
- Removed the unused build-essential dependency
- Require Chef 12.9 or later so we don't introduce issues with the apt cookbook
- Set the Varnish TTL
- Moved files and templates out of the default directories. This was a Chef 11-ism
- Renamed the resource files to let chef auto generate the resource names properly
- Removed the usage of kind_of in the resources since that's a LWRP-ism
- Swapped name_attribute for name_property in the resources
- Removed unnecessary default_action from the resources
- Removed the name properties from the resources since Chef auto generates these for us
v3.4.0
- Adds support Varnish 5
- Updates reload-vcl file from upstream packaging
- Add varnish5 TravisCI tests
Known Bugs:
- Specifying
5.0
as the major version can cause an older version to be installed, use5
instead. https://github.com/sous-chefs/varnish/issues/150
v3.3.1
- Remove upper bound on yum cookbook dependency. #147
- Add repo_gpgcheck to redhat varnish repo. #145
v3.3.0
- Updates to the new upstream varnish repo. https://github.com/sous-chefs/varnish/issues/140
- Deprecates using the upstream varnish 4 repo on CentOS 7 (distro version still works). https://github.com/sous-chefs/varnish/issues/142
v3.2.0
- Links /etc/sysconfig/varnishlog and varnishncsa to defaults file in /etc/default. Fixes https://github.com/sous-chefs/varnish/issues/125.
- Fixes default varnishncsa format string (double quotes where getting added).
- Fixes an conflict when using both varnishlog and varnishncsa.
- Fixes distro_install integration tests. https://github.com/sous-chefs/varnish/issues/126
- Reverts the removal of reload-vcl since this is not fixed upstream in ubuntu's system packages yet.
v3.1.0
- Varnish expects the varnish instance name to be
hostname
by default however this is sometimes different thenhostname -s
which is used byohai's hostname
. This seemed to only be an issue on CentOS 7.2. - Use /etc/varnish/varnish.params for systemd init file. This is what the package uses and I think will remove some confusion about how settings are set. #103
- Remove /usr/share/varnish/reload-vcl on debian. This was added to support the '-j' option in varnish 4.1 however it has been fixed upstream.
- including yum-epel for centos
- Removing old testing files(CircleCi, kitchen-rackspace, rake) and replacing with (TravisCI, kitchen-dokken, delivery).
- adding integration testing in ci.
v3.0.0
- Move recipes in default to custom resources / Move recipe and lwrp defaults config to custom resource
- Remove unused properties
- Don't append '.vcl' to file name
- Fix percent_of_total_mem function
- Include default recipe in integrations tests
- Add configure recipe
- Don't use default recipe to install/setup varnish
- Don't fetch the repository key over insecure HTTP
v2.4.0
- Add additional attributes to allow use of template source from a wrapper cookbook
- Move define_systemd_daemon_reload to helpers (#97)
- Fix Chef::Exceptions::ChecksumMismatch error
- Set Ruby vers to 2.2.3 to satisfy ruby_dep requirements (#104)
v2.3.0
- Fix chef 12.5 compatibility. This required a bunch of workarounds we should fix later.
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

v0.9.10
Bug
- COOK-3531 - Fix default instance name
v0.9.8
Improvement
- COOK-3095 - Add MiniTest Chef Handler and Test Kitchen
v0.9.6

v0.9.4
- [COOK-1261] - fix issues with default.vcl handling
v0.9.0
- [COOK-873] - full daemon configuration through attributes
- [COOK-1091] - fix path for default.vcl, via COOK-873
