Class: tripleo::profile::base::etcd

etcd profile for tripleo

Parameters

bind_ip

(optional) IP to bind etcd service to. Defaults to ‘127.0.0.1’.

client_port

(optional) etcd client listening port. Defaults to ‘2379’.

peer_port

(optional) etcd peer listening port. Defaults to ‘2380’.

nodes

(Optional) Array of host(s) for etcd nodes. Defaults to lookup(‘etcd_node_ips’, undef, undef, []).

certificate_specs

(Optional) The specifications to give to certmonger for the certificate it will create. Note that the certificate nickname must be ‘etcd’ in the case of this service. Example with hiera:

tripleo::profile::base::etcd::certificate_specs:
  hostname: <overcloud controller fqdn>
  service_certificate: <service certificate path>
  service_key: <service key path>
  principal: "etcd/<overcloud controller fqdn>"

Defaults to {}.

enable_internal_tls

(Optional) Whether TLS in the internal network is enabled or not. Defaults to lookup(‘enable_internal_tls’, undef, undef, false)

step

(Optional) The current step in deployment. See tripleo-heat-templates for more details. Defaults to Integer(lookup(‘step’))

Parameters:

  • bind_ip (Any) (defaults to: '127.0.0.1')
  • client_port (Any) (defaults to: '2379')
  • peer_port (Any) (defaults to: '2380')
  • nodes (Any) (defaults to: lookup('etcd_node_names', undef, undef, []))
  • certificate_specs (Any) (defaults to: {})
  • enable_internal_tls (Any) (defaults to: lookup('enable_internal_tls', undef, undef, false))
  • step (Any) (defaults to: Integer(lookup('step')))
