memcached Cookbook
Provides a custom resource for installing instances of memcached. Also ships with a default recipe that uses attributes to configure a single memcached instance on a host.
Requirements
Platforms
- Debian / Ubuntu and derivatives
- RHEL and derivatives
- Fedora
- openSUSE/SLES
Chef
- Chef 12.7+
Cookbooks
- runit (not used by default)
Attributes
The following are node attributes are used to configure the command line options of memcached 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['extra_cli_options']
- Array of single item options suchas -L for large pages. -
memcached['ulimit']
- maxfile limit to set (needs to be at least maxconn)
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 system's native init system (sys-v, upstart, or systemd). For backwards compatibility there is also a runit provider that can be used if desired.
Actions
- :start: Starts (and installs) an instance of memcached
- :stop: Stops an instance of memcached
- :enable: Enabled (and installs) an instance of memcached to run at boot
- :restart: Restarts an instance of memcached
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 experimental config options, such as: ['maxconns_fast', 'hashpower']
- :extra_cli_options - an array of additional config options, such as: ['-L']
- :ulimit - the ulimit setting to use for the service
- :template_cookbook - the cookbook containing the runit service template. default: memcached
- :disable_default_instance - disable the default 'memcached' service installed by the package, default: true
- :log_level - The level at which we log, default to 'info'. Choose from: 'info', 'debug', 'trace' which map to '-v', '-vv' or '-vvv' arguments.
Examples
Create a new memcached 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 action :remove end
Specify the runit provider to maintain legacy behavior (including optional usage of legacy actions)
memcached_instance_runit 'super_custom_memcached' do action :create end

memcached Cookbook CHANGELOG
This file is used to list changes made in each version of the memcached cookbook.
5.0.2 (2018-01-17)
- Use binary_path helper throughout code for consistency
5.0.1 (2018-01-10)
- Fix ulimit for runit based services
- Use Systemd User directive which is more secure
- Fix experimental_options to be properly spaced
5.0.0 (2017-09-06)
Breaking changes
- Support for RHEL 5 has been removed. This removes the cookbook dependency on yum-epel as well
- Runit support has been marked as deprecated and will be removed in a future release of this cookbook. We highly recommend you utilize the native init system of your distro to have the best experience with memcached.
Other fixes
- Fix using the resource to setup a sys-v init script on Fedora platforms
- Fix Amazon Linux support on Chef >= 13
- Don't delete the memcached init script if the instance name is 'memcached' and we're specifying the instance_name on the resource instead of using the resource's name
- Added new resource property for
log_level
and fixed logging setup in the resources - Run failures with runit have been resolved
- Minor property cleanup in the resources
- Avoid an extra blank line in the command options
- Add Debian Sys-V script for Debian to allow for Debian 7 support
- Pull in systemd unit file security settings from upstream
4.1.0 (2017-05-06)
- Require Chef 12.7+ to workaround action_class bug
4.0.1 (2017-04-26)
- Update apache2 license string
4.0.0 (2017-03-13)
- Require 12.5 and remove dependency on compat_resource
- Let chef pick the best init system instead of hardcoding init systems per distro / version
- Avoid Chef 13 deprecation warnings
- Test with Local Delivery instead of Rake
- Add extra_cli_options for passing anything else you want in to the binary
- Use a consistent memcached path in the sysv script
3.0.3 (2017-01-19)
- Add missing
user
variable to template in instance_sysv_init resource - Move testing to a test recipe and improve that testing
- Depend on the latest compat_resource
- Use :template_cookbook property for all template resources to fix specifying a different cookbook
3.0.2 (2016-06-28)
- Remove Chef 11 compatibility check in the metadata
- Better handle specifying non-standard init systems
3.0.1 (2016-06-23)
- Remove smartos from the supported platforms metadata as it's not longer supported
- Add opensuse and opensuseleap as supported platforms in the metadata
- Increase the compat_resource depdency from >= 12.9 to >= 12.10 to bring in important fixes
- Add requirement of Chef 12 to the metadata
- Restart the service on failure when running under systemd
- Disable FC023 in Foodcritic tests
3.0.0 (2016-05-24)
The preferred method of use for this cookbook is now the custom resources via your own wrapper cookbook. The default recipe simply wraps the custom resource and allows you to set attributes instead of directly changing custom resource properties. To support this goal, the custom resource now uses the native init system of your OS by default (sys-v, upstart or systemd). The Runit provider is still present for backwards compatibility, but must be specified. See the readme for an example of how to do that with the custom resource. The default recipe does not support using runit and runit is no longer an init system we suggest users use.
The ulimit attribute and custom resource property behavior have been changed. Ulimit now takes the actual ulimit value as a string or int. Previously a boolean value was passed and if true the connection max was set. This gives users additional control over the ulimit value.
SmartOS support has been removed. SmartOS support was never properly implemented and didn't support the custom resource. We've chosen to remove it instead of leaving partially functional and untested code in place.
Other CHANGES
- Testing has been improved with additional specs and integration tests that better match the capabilities of the cookbook
- Support has been added for platforms that lacked the Runit package, specifically opensuse -
2.1.0 (2016-03-16)
- Added a new property, disable_default_instance, to the instance custom resource for disabling the package installed memcached service. This prevents resource merging from resulting in a service that isn't disabled.
- Updated the custom resource to avoid potential namespace conflicts
- Require the latest custom_resource to avoid failures and extra warning messages
- Resolved nil attribute deprecation warnings
- Added maintainers files
2.0.3 (2016-02-16)
- Fix template whitespace location that resulted in bad command
2.0.2 (2015-11-20)
- Push new version to Supermarket to deal with bad artifact
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
intoinstall.rb
andconfigure.rb
so that memcached_instance only starts the specified number of instances
- split
added attributes
logfilepath
,version
,threads
,experimental_options
, andulimit
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}"
