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

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

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',
    },
}
