Overview

This module installs and configures the Hitch TLS proxy, and adds a define to add domains.

Module Description

This module installs the hitch package, and controls the hitch service and the configuration file.

There is a defined type to add domains with key, certificate, as well as an optional certificate chain and dh parameter. The TLS files are concatenated into one PEM file, and added to the configuration file.

Setup

What hitch affects

Package "hitch"
Service "hitch"
Directory "/etc/hitch"
Configuration file "/etc/hitch/hitch.conf"
A PEM file inside /etc/hitch for each domain, with TLS key, certificate, ca certificate chain, and dh parameters.

Setup Requirements

The module requires that the "hitch" package is available in a reachable package repository.

If osfamily is RedHat, the module adds the epel-release package with ensure_packages
If osfamily is Debian, you are expected to provide a repository containing the "hitch" package.

Beginning with hitch

To start using hitch, you need to include the hitch class, and add at least one hitch::domain.

include ::hitch
hitch::domain { 'example.com':
  key_source  => '/tmp/key',
  cert_source => '/tmp/cert.pem',
}

When configured with this module, hitch will listen by default on all interfaces, port 443/TCP for both IPv4 and IPv6, and forward TCP connections to localhost, port 80.

Usage

The module is documented in the REFERENCE.md file.

When using hitch with varnish or nginx, one can provide information about the connecting client, like the connecting IP Address and port, to varnish by using the PROXY protocol. The backend should be configured with an additional listening port for this protocol.

class { '::hitch':
  write_proxy_v2 => 'on',
  backend        => '[::1]:6086'
}

In case of varnish, add an extra "-a" parameter for a separate listening port:

-a '[::1]:6086,PROXY'

…to have it listen on port 6086, using the PROXY protocol instead of the HTTP protocol.

For more information about the PROXY protocol, see http://www.haproxy.org/download/1.5/doc/proxy-protocol.txt

Limitations

You need to define at least one hitch::domain, or the hitch service will not start.

Development

Issues and pull requests welcome.

Defined types

`hitch::domain`

This define installs pem files to the config root, and configures them in the hitch config file.

The CA certificate (if present), server certificate, key and DH parameters are concatenated, and placed in the hitch configuration.

You can specify cacert, cert and key with either _content or _source suffix.

Examples

website with TLS files from managed node

hitch::domain { 'example.com':
  cacert_source => '/etc/pki/tls/certs/ca.pem',
  cert_source   => '/etc/pki/tls/certs/example.com.pem',
  key_source    => '/etc/pki/tls/private_keys/example.com.pem',
}

website with TLS content from hiera

class profile::hitch (
   Hash $domains = {},
) {
  $domains.each |$domain_title, $domain_params| {
    hitch::domain { $domain_title:
      * => $domain_params,
