Class profile::wmcs::services::etcd_discovery

Etcd-discovery server profile

The only one of these that would typically need a hiera definition is
 $prefix_url which should be set to the discovery endpoint host, e.g.
 https://etcd-discovery.codfw1dev.wmcloud.org

Parameters:

  • prefix_url (String) (defaults to: lookup('profile::wmcs::services::etcd_discovery::prefix_url', { 'default_value' => 'http://example.com' }))
  • web_service_address (String) (defaults to: lookup('profile::wmcs::services::etcd_discovery::web_service_address', { 'default_value' => ':8087' }))
  • endpoint_location (String) (defaults to: lookup('profile::wmcs::services::etcd_discovery::endpoint_location', { 'default_value' => 'http://127.0.0.1:2379' }))
