Installs/configures a single memcached instance managed by the systems init system. Also provides a custom resource to set up one or more memcached instances running under runit.

Requirements

Platforms

Debian / Ubuntu
RHEL and derivatives
Fedora
openSUSE/SLES
SmartOS base64 1.8.1 - Note that SMF directly configures memcached with no opportunity to alter settings. If you need custom parameters, use the memcached_instance provider instead.

Chef

Chef 12+

Cookbooks

runit
yum-epel
compat_resource

Attributes

The following are node attributes are used to configure /etc/memcached.conf if using the default.rb recipe. They are not used if using the memcached_instance custom resource.

memcached['memory'] - maximum memory for memcached instances.
memcached['user'] - user to run memcached as.
memcached['port'] - TCP port for memcached to listen on.
memcached['udp_port'] - UDP port for memcached to listen on.
memcached['listen'] - IP address for memcache to listen on, defaults to 0.0.0.0 (world accessible).
memcached['maxconn'] - maximum number of connections to accept (defaults to 1024)
memcached['max_object_size'] - maximum size of an object to cache (defaults to 1MB)
memcached['logfilepath'] - path to directory where log file will be written.
memcached['logfilename'] - logfile to which memcached output will be redirected in $logfilepath/$logfilename.
memcached['threads'] - Number of threads to use to process incoming requests. The default is 4.
memcached['experimental_options'] - Comma separated list of extended or experimental options. (array)
memcached['ulimit'] - boolean true will set the ulimit to the maxconn value

Usage

This cookbook can be used to to setup a single memcached instance running under the system's init provider by including memcached::default on your runlist. The above documented attributes can be used to control the configuration of that service.

The cookbook can also within other cookbooks in your infrastructure with the memcached_instance custom resource. See the documentation below for the usage and examples of that custom resource.

Custom Resources

instance

Adds or removes an instance of memcached running under the runit supervisor.

Actions

:add: Add a new instance
:remove: Remove an existing instance

Properties

:memory - the amount of memory allocated for the cache. default: 64
:port - the TCP port to listen on. default: 11,211
:udp_port - the UDP port to listen on. default: 11,211
:listen - the IP to listen on. default: '0.0.0.0'
:maxconn - the maximum number of connections to accept. default: 1024
:user - the user to run as
:threads - the number of threads to use
:max_object_size - the largest object size to store
:experimental_options - an array of additional config options
:ulimit - the ulimit setting to use for the service
:template_cookbook - the cookbook containing the runit service template. default: memcached

Examples

Create a new memached instance named super_custom_memcached:

memcached_instance 'super_custom_memcached' do
  port 11_212
  memory 128
end

Stop and disable the super_custom_memcached instance:

memcached_instance 'super_custom_memcached'  do

memcached Cookbook CHANGELOG

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

2.0.1 (2015-11-19)

Push new version to Supermarket to deal with bad artifact

2.0.0 (2015-11-10)

BREAKING CHANGES:
- The user and group attributes have been removed and are instead handled by a helper that picks the appropriate user / group based on the platform
- The memcached_instance definition that used both passed values and node attributes for configuration has been rewritten as a 12.5 custom resource with compat_resource providing backwards compatibility to all Chef 12.X releases. This new custom resource handles the installation of memcached and all configuration is passed in via custom resource properties. See the readme for examples of how to use this new resource. This change should greatly improve the ability to use memcached_instance within wrapper cookbooks.

1.9.0 (2015-11-05)

NOTE: This will be the last version of this cookbook that supports Chef 11 and the traditional attribute / resource hybrid setup for memcached instances. After this release this cookbook will function with attributes for a simple install or Chef 12.5 custom resources for creating individual memcached instances. If you utilize memcached instances using the attributes to define the config you'll need to pin to ~1.0 and later update to the new format in ~2.0.

Debian/Ubuntu switched the user that memcached runs under from nobody to memcache. Updated the cookbook to use this user on those platforms and create it in case we're on an older distro release that didn't yet have that user
Removed use of shellout that was causing issues for users
Improved the workaround on Debian/Ubuntu for not starting the service on package install so that it doesn't show up as a changed resource on every Chef run
Updated Chefspec to 4.X and added additional specs
Add oracle to the metadata
Add issues_url and source_url to the metadata
Add new contributing.md, maintainers.md, and testing.md docs
Add travis and cookbook version badges to the readme
Clarified Chef 11 is the minimum required chef release
Updated platforms in the Kitchen config
Added chefignore file
Removed all hash rockets
Added a .foodcritic file with exclusions
Updated travis to use their container infrastructure, chef-dk for testing deps, and kitchen-docker for integration testing
Added a Rakefile to simplify testing
Removed yum as a dependency as it wasn't being used.
Removed attributes from the metadata as they hadn't been updated

v1.8.0 (2015-08-11)

updated serverspec tests to pass (See 3c7b5c9)
deconflict memcached_instance runit definition from default init (See b06d2d)
- split default.rb into install.rb and configure.rb so that memcached_instance only starts the specified number of instances
added attributes logfilepath, version, threads, experimental_options, and ulimit
NOTE: if memcached_instance name is not specified or set to "memcached", the instance name will be "memcached". If anything else is specified, the instance name will be "memcached-${name}"
