# haproxy

Install HAProxy.

## Tasks

Everything is in the `tasks/main.yml` file.

## Available variables

* `general_package_release`: which Debian release to use generally (default: `stable`).
* `haproxy_package_release`: which Debian release to use for HAProxy (default: `general_package_release`).

The full list of variables (with default values) can be found in `defaults/main.yml`.

## Configuration templates

The roles compiles a `haproxy.cfg` file based on templates that are looked up in that order :
1. `{{ playbook_dir}}/templates/haproxy/haproxy.{{ inventory_hostname}}.cfg.j2`
2. `{{ playbook_dir}}/templates/haproxy/haproxy.{{ host_group}}.cfg.j2` (NB : `host_group` is not a core variable, it must be defined in `group_vars` files.)
3. `{{ playbook_dir}}/templates/haproxy/haproxy.default.cfg.j2`

If nothing is found, the role falls back to the template embedded in the role : `templates/haproxy.default.cfg.j2`
