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.

Cookbooks

There are no external cookbook dependencies.

Installation

Just place the dpkg_packages directory in your chef cookbook directory and upload it to your Chef server.

Usage

Simply add recipe[heartbeat] to the run list of the servers that will integrate the heartbeat cluster. You can edit the file file/default/authkeys in order to add more security to your heartbeat cluster.

This cookbook doesn't have templates, all configuration files are generated dinamically depending of the keys and their values of the attributes hashes.

Configuration example:

node['heartbeat']['ha_cf']['logfacility'] = "local0"
node['heartbeat']['ha_cf']['auto_failback'] = "off"
node['heartbeat']['ha_cf']['ucast'] = "eth0 1.1.1.1"
node['heartbeat"]['ha_cf']['node'] = [ "node1", "node2" ]

node["heartbeat"]["haresources"] = [
  {
    "node" => "node1",
    "resources" => [
      "IPaddr::135.9.8.7/24/eth0/135.9.8.210",
      "135.9.216.3/28/eth0/135.9.216.12 httpd",
      "10.0.0.170 Filesystem::/dev/sda1::/data1::ext2"
    ]
  }
]

Will generate the following /etc/ha.d/ha.cf file:

logfacility local0
auto_failback off
ucast eth0 1.1.1.1
node node1
node node2

And the following /etc/ha.d/haresources file: node 1 \ IPaddr::135.9.8.7/24/eth0/135.9.8.210 \ 135.9.216.3/28/eth0/135.9.216.12 httpd \ 10.0.0.170 Filesystem::/dev/sda1::/data1::ext2

Recipes

default

Installs and configures Heartbeat according the settings of the node attributes. Also it disables de services set in the node['heartbeat']['services'] attribute.

services

This recipe will sanitize the services that are set in the node['heartbeat']['services'] attribute in order to Chef doesn't start them in the inactive node.

Attributes

ha_cf

Hash that contains the parameters of the /etc/ha.d/ha.cf file. If the elements are arrays, they will be added with the same parameter but with different values.

services

It could be false or an array that contains the services that will be managed by heartbeat.

haresources

It could be false or it could be an array of hashes with the resources definitions. If it is false, the /etc/ha.d/haresources will not be generated.

Resources and Providers

This cookbook provide some service providers that override some actions in order to them couln't be started by Chef.

Libraries

There are none defined.

Development

Pull requests are very welcome! Make sure your patches are well tested. Ideally create a topic branch for every separate change you make.
