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 (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.

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.

Attributes

Attribute	Description	Default
install_method	One of: 'package', 'source', 'ppa'	`package`
proxies	Array of proxy names for the default haproxy_instance[haproxy]	[]
config	global config of resource haproxy_instance[haproxy]	See `attributes/default.rb`
tuning	global tuning of resource haproxy_instance[haproxy]	See `attributes/default.rb`

And more! (see attributes/*.rb)

Resources

haproxy_instance

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

Attribute	Description	Default
verify	whether to perform resource whitelist validation	true
config	global keywords for process mgmt	`['daemon']`
tuning	global keywords for performance	`['maxconn 256']`
debug	global keyword for debugging ('debug', 'quiet')	`nil`
proxies	array of proxies, see `default` recipe for example	[]

haproxy_proxy

The simplest proxy representation and base class for the other
proxy resources (peers, userlist, defaults, frontend, backend, listen).

Attribute	Description	Default
verify	whether to perform resource whitelist validation	true
type	String denoting proxy type. (defaults, frontend, backend, listen, peers, userlist)	nil
config	array of keywords, validated against specified type	[]

haproxy_peers

Maps to a peers block in haproxy configuration. Not actually a proxy,
but treating it like one is useful for code reusability. Don't judge me.

Attribute	Description	Default
verify	whether to perform resource whitelist validation	true
peers	array of hashes. each hash requires 'name', 'config' keys	[]
config	array of peers keywords. validated against whitelist	[]

haproxy_userlist

Maps to a userlist block in haproxy configuration. Also not actually a proxy,
as such.

Attribute	Description	Default
verify	whether to perform resource whitelist validation	true
groups	array of hashes. hashes require 'name', 'config' keys	[]
users	array of hashes. hashes require 'name', 'config' keys	[]
config	array of userlist keywords, validated against whitelist	[]

haproxy_defaults

Maps to a 'defaults' block in haproxy configuration. Convention
suggests that resource names be capitalized (e.g. haproxy_defaults[HTTP]).

Attribute	Description	Default
verify	whether to perform resource whitelist validation	true
mode	specifies listener mode (http, tcp, health)	nil
default_backend	argument to `default_backend` keyword	nil
balance	desired balancing algo (see docs for permitted values)	nil
source	argument to source keyword	nil
config	array of defaults keywords, validated against whitelist	[]

haproxy_frontend

Maps to a frontend block in the instance configuration,
and typically to one or more listening ports or sockets.

Attribute	Description	Default
verify	whether to perform resource whitelist validation	true
mode	specifies listener mode (http, tcp, health)	nil
acls	array of hashes, each requiring 'name', 'criterion' keys	[]
description	string describing proxy	nil
bind	args to `bind` keyword	nil
default_backend	argument to `default_backend` keyword	nil
use_backends	array of hashes, each requiring 'backend', 'condition', keys	[]
config	array of frontend keywords, validated against whitelist	[]

haproxy_backend

Maps to a backend configuration block in haproxy configuration.

Attribute	Description	Default
verify	whether to perform resource whitelist validation	true
mode	specifies listener mode (http, tcp, health)	nil
acls	array of hashes, each requiring 'name', 'criterion' keys	[]
description	string describing proxy	nil
balance	desired balancing algo (see docs for permitted values)	nil
source	string specifying args to source keyword	nil
servers	array of hashes, each requiring 'name', 'address', 'port' keys. 'config' key optional	[]
config	array of backend keywords, validated against whitelist	[]

haproxy_listen

Maps to a listen configuration block, combines frontend and backend config
blocks into a single proxy. Less flexible, but more concise. Typically used
for tcp-mode proxies with a 1:1 frontend:backend mapping.

Attribute	Description	Default
verify	whether to perform resource whitelist validation	true
mode	specifies listener mode (http, tcp, health)	nil
acls	array of hashes, each requiring 'name', 'criterion' keys	[]
description	string describing proxy	nil
balance	desired balancing algo (see docs for permitted values)	nil
source	string specifying args to source keyword	nil
servers	array of hashes, each requiring 'name', 'address', 'port' keys. 'config' key optional	[]
bind	args to `bind` keyword	nil
default_backend	argument to `default_backend` keyword	nil
use_backends	array of hashes, each requiring 'backend', 'condition', keys	[]
config	array of listen keywords, validated against whitelist	[]
