haproxy-ng cookbook
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 a running haproxy daemon -
haproxy_proxy
: the "core" proxy resource, which maps to a specific proxy
Additional resources 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 type.
Suggested background reading:
- Manual
- This README, the modules in
libraries/helper.rb
, and the individual HWRPs
Recipes
haproxy-ng::default
Configures a default 'haproxy' instance and service via the config
, tuning
,
and proxies
cookbook attributes (which correspond to the resource attributes).
This recipe also provides a useful example of using the provided helper to map a
list of proxies by name to their corresponding resources in the resource collection
via the Haproxy::Helpers#proxy
method. It also illustrates the suggested pattern of
proxying service reloads through a validating execute resource.
haproxy-ng::install
Installs haproxy via the node['haproxy']['install_method']
method.
Currently only supports installation from a package.
haproxy-ng::service
Configures a default-named ("haproxy") service resource.
Useful for typical installs running a single haproxy service ("service" in the
init-system sense) under the default 'haproxy' service name.
Service providers, or those running multiple haproxy instances will need to
configure a service instance per haproxy_instance.
