haproxy-ng cookbook Build Status

A resource-driven cookbook for configuring HAProxy.

Cookbook builds on 2 core resources:

  • haproxy_instance: the "parent" resource, which maps to a complete configuration and (probably) a running haproxy daemon
  • haproxy_proxy: the "core" proxy resource, which maps to a specific proxy

Additional resources haproxy_peers, haproxy_userlist, haproxy_frontend,
haproxy_backend, haproxy_defaults, and haproxy_listen extend the haproxy_proxy
resource with additional validation for common configuration keywords for their respective
proxy types.

Suggested background reading:

  • The Fine Manual
  • This README, the modules in libraries/00_helpers.rb, and the individual resources/providers
  • the test target and example wrapper cookbook 'test/fixtures/cookbooks/my-lb'

Recipes

haproxy-ng::default

Configures a default instance, 'haproxy_instance[haproxy]', and corresponding
'haproxy' service via the config, tuning, and proxies cookbook attributes
(which are mapped onto the corresponding resource attributes).

This recipe also provides a useful example of using the provided helper,
Haproxy::Helpers#proxy, to map a list of proxies to their corresponding
resources in the resource collection. It also illustrates the recommended
pattern of proxying service reloads through a validating execute resource.

See wrapper cookbook example at 'test/fixtures/cookbooks/my-lb'.

haproxy-ng::install

Installs haproxy via the node['haproxy']['install_method'] method.
Supports 'package', 'source', and 'ppa'.

haproxy-ng::service

Configures a default-named ("haproxy") service resource.

Useful for typical installs running a single haproxy daemon under the default
'haproxy' service name. Service providers, or those running multiple haproxy
daemons on a single host will most likely want to configure a service instance
per haproxy_instance.

Resources

haproxy_instance

The "parent" resource. Maps 1-to-1 with a generated haproxy config file,
and most likely to a running service.

<table>
<thead>
<tr>
<th>Attribute</th>
<th>Description</th>
<th>Default Value</th>
</tr>
</thead>
<tbody>

Array of global keywords relevant to process management.
See libraries/00_helpers.rb or haproxy manual for permissible keywords.

Array of Chef::Resource::HaproxyProxy instances
(haproxy_{peers,userlist,defaults,frontend,backend,listen} included).
See the default recipe for an example of using the provided
Haproxy::Helpers#proxy method to generate this list from the
resource_collection.
</td>
<td><code>[]</code></td>
</tr>
</tbody>
</table>

haproxy_proxy

proxy resources (peers, userlist, defaults, frontend, backend, listen).

haproxy_peers

but treating it like one is useful for code reusability. Don't judge me.

<table>
<thead>
<tr>
