Setup requirements

All module dependencies are listed in this module's metadata.json.

Usage - Configuration options and additional functionality

Basic Etcd

To install and run a single instance of etcd it's sufficient to just include the etcd class:

include etcd

All configuration for etcd.yaml is done via the config parameter, example:

class { 'etcd':
  config => {
    'data-dir' => '/var/lib/etcd',
    'wal-dir'  => '/var/lib/etcd/wal',

Clustered Etcd

The following is an example of a clustered etcd setup. Adjust name, initial-advertise-peer-urls and advertise-client-urls for each host in the cluster.

class { 'etcd':
  config => {
    'data-dir'                    => '/var/lib/etcd',
    'name'                        => 'infra1',
    'initial-advertise-peer-urls' => '',
    'listen-peer-urls'            => '',
    'listen-client-urls'          => '',
    'advertise-client-urls'       => '',
    'initial-cluster-token'       => 'etcd-cluster-1',
    'initial-cluster'             => 'infra0=,infra1=,infra2=',
    'initial-cluster-state'       => 'new',

Etcd Upgrades

Upgrades using this module are performed by increasing the value provided to version.

If the previous version was 3.4.7 then the following would upgrade etcd to 4.0.0:

class { 'etcd':
  version => '4.0.0',

Puppet will download the new etcd, update the symlinks for etcd binary and restart the etcd service.
