Limitations - OS compatibility, etc.
Development - Guide for contributing to the module

Overview

This module:

Installs the consul-template binary (via url or package)
Optionally installs a user to run it under
Installs a configuration file to /etc/consul-template/config.json
Manages the consul-template service via upstart, sysv, or systemd

Puppet 3 Support

Please note that the master branch of this module does not support Puppet 3!

On 31st December 2016, support for Puppet 3.x was withdrawn. As such, this module no longer supports Puppet 3 - if you require Puppet 3 compatibility, please use the latest version 1.x version from the Puppet Forge, or the puppet3 branch in Git.

Usage

The simplest way to use this module is:

include ::consul_template

Consul-template Options

consul-template options can be passed via hiera:

consul_template::config_defaults:
  deduplicate:
    enabled: true
  log_level: info
  max_stale: 10m
  retry:
    attemtps: 12
    backoff: 250ms
  kill_signal: SIGINT
  reload_signal: SIGHUP
  retry: 10s
  syslog: true
  token: <consul token>

Or via class parameters:

 class { 'consul_template':
   service_enable   => false
   config_hash      => {
     log_level => 'debug',
     wait      => '5s:30s',
     max_stale => '1s'
   }
 }

Watch files

To declare a file that you wish to populate from Consul key-values, use the watch define. This requires a source .ctmpl file and the file on-disk that you want to update.

consul_template::watch { 'common':
    template      => 'data/common.json.ctmpl.erb',
    template_vars => {
        'var1' => 'foo',
        'var2' => 'bar',
    },
    config_hash   => {
      perms       => '0644',
      destination => '/tmp/common.json',
      command     => 'true',
    },
}
