Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

This cookbook is a fork of belyaevp corosync cookbook

Installs and configures Corosync Cluster Engine.

Requirements

Platforms

  • Debian 9
  • Ubuntu >= 16.04
  • RHEL/CentOS >= 7

Chef

  • Chef 12.19+

Dependencies

Recipes

Installs the Corosync, and manages the Corosync service. The recipe does not at this time manage any configuration.

Resources

default

The default resource to configure the Corosync.

Properties

The following list contains only some of the properties. For other options please see the corosync.conf.5 manual and the resources/default.rb file.

  • totem_version - Integer. Specifies the version of the configuration file. Currently the only valid version for this directive is 2.
  • totem_crypto_cipher - This specifies which cipher should be used to encrypt all messages. Valid values are none (no encryption), aes256, aes192, aes128 and 3des. Enabling crypto_cipher, requires also enabling of crypto_hash.
  • totem_crypto_hash - This specifies which HMAC authentication should be used to authenticate all messages. Valid values are none (no authentication), md5, sha1, sha256, sha384 and sha512.
  • totem_secauth - This specifies that HMAC/SHA1 authentication should be used to authenticate all messages. It further specifies that all data should be encrypted with the nss library and aes256 encryption algorithm to protect data from eavesdropping. WARNING: This parameter is deprecated. It's recomended to use combination of crypto_cipher and crypto_hash.
  • totem_transport - This directive controls the transport mechanism used. If the interface to which Corosync is binding is an RDMA interface such as RoCEE or Infiniband, the "iba" parameter may be specified. To avoid the use of multicast entirely, a unicast transport parameter "udpu" can be specified. This requires specifying the list of members in nodelist directive, that could potentially make up the membership before deployment.
  • node_list - Node list in the following format. javascript [ { 'ring: Int', 'node_name: String', 'ip_addr: String' }, { ... } ]
  • totem_interface_bindnetaddr - Interface to bind the ring
  • totem_ip_version - Specifies version of IP to use for communication. Value can be one of ipv4 or ipv6. Default (if unspecified) is ipv4.
  • totem_heartbeat_failures_allowed - Configures the optional HeartBeating mechanism for faster failure detection. Keep in mind that engaging this mechanism in lossy networks could cause faulty loss declaration as the mechanism relies on the network for heartbeating.

Usage

  • Add depends 'corosync' to your cookbook's metadata.rb
  • Use recipe 'default' to install the Corosync

Resource-based config

  • Use the resources shipped in cookbook in a recipe, the same way you'd use core Chef resources (file, template, directory, package, etc).
  • Some healthy defaults are provided (e.g. totem version)
include_recipe 'corosync'

corosync 'config' do
  totem_transport 'udpu'
  totem_interface_bindnetaddr node_ip
  node_list corosync_node_list
  action :create
end

JSON-based config

  • Specify the JSON attributes for your node as follows
"normal": {
  "corosync": {
    "config": {
      "totem": {
        "version": 2,
        "secauth": "on"
      }
    }
  }
}
  • Call the resource default
corosync 'config' do
  action :create
end
