Description

This is a cookbook for managing RabbitMQ with Chef. It is intended for 2.6.1 or later releases.

Version 2.0 Changes

The 2.0 release of the cookbook defaults to using the latest version available from RabbitMQ.com via direct download of the package. This was done to simplify the installation options to either distro package or direct download. The attributes use_apt and use_yum have been removed as have the apt and yum cookbook dependencies. The user LWRP action :set_user_tags was changed to :set_tags for consistency with other actions.

This release was tested with:

  • CentOS 5.8: 3.0.4 (distro release unsupported)
  • CentOS 6.3: 3.0.4/2.6.1 (no plugin support)
  • Debian 6: 3.04 (distro release unsupported)
  • Ubuntu 10.04: 3.0.4 (distro release unsupported)
  • Ubuntu 12.04: 3.0.4/2.7.1

Recipes

default

Installs rabbitmq-server from RabbitMQ.com via direct download of the installation package or using the distribution version. Depending on your distribution, the provided version may be quite old so they are disabled by default. If you want to use the distro version, set the attribute ['rabbitmq']['use_distro_version'] to true. You may override the download URL attribute ['rabbitmq']['package'] if you wish to use a local mirror.

The cluster recipe is now combined with the default and will now auto-cluster. Set the ['rabbitmq']['cluster'] attribute to true, ['rabbitmq']['cluster_disk_nodes'] array of node@host strings that describe which you want to be disk nodes and then set an alphanumeric string for the erlang_cookie.

To enable SSL turn ssl to true and set the paths to your cacert, cert and key files.

Resources/Providers

There are 3 LWRPs for interacting with RabbitMQ.

user

Adds and deletes users, fairly simplistic permissions management.

  • :add adds a user with a password
  • :delete deletes a user
  • :set_permissions sets the permissions for a user, vhost is optional
  • :clear_permissions clears the permissions for a user
  • :set_tags set the tags on a user
  • :clear_tags clear any tags on a user

Examples

rabbitmq_user "guest" do
  action :delete
end

rabbitmq_user "nova" do
  password "sekret"
  action :add
end

rabbitmq_user "nova" do
  vhost "/nova"
  permissions ".* .* .*"
  action :set_permissions
end

rabbitmq_user "joe" do
  tag "admin,lead"
  action :set_tags
end

vhost

Adds and deletes vhosts.

  • :add adds a vhost
  • :delete deletes a vhost

Example

rabbitmq_vhost "/nova" do
  action :add
end

plugin

Enables or disables a rabbitmq plugin. Plugins are not supported for releases prior to 2.7.0.

  • :enable enables a plugin
  • :disable disables a plugin

Example

rabbitmq_plugin "rabbitmq_stomp" do
  action :enable
end

rabbitmq_plugin "rabbitmq_shovel" do
  action :disable
end

policy

sets or clears a rabbitmq policy.

  • :set sets a policy
  • :clear clears a policy
  • :list lists policys

Example

rabbitmq_policy "ha-all" do
  pattern "^(?!amq\\.).*"
  params {"ha-mode"=>"all"}
  priority 1
  action :set
end

rabbitmq_policy "ha-all" do
  action :clear
end

Limitations

For an already running cluster, these actions still require manual intervention:

  • changing the :erlang_cookie
  • turning :cluster from true to false

The rabbitmq::chef recipe was only used for the chef-server cookbook and has been moved to chef-server::rabbitmq.
