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.

package_name 'varnish'
vendor_repo true

files that come with your distro package will be used instead.

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
v0.9.12 (2014-03-12)

v0.9.8
