Overview

Class swift::containerreconciler

Parameters

[*enabled*]
  (optional) Should the service be enabled.
  Defaults to true

[*manage_service*]
  (optional) Whether the service should be managed by Puppet.
  Defaults to true.

[*package_ensure*]
  (optional) Value of package resource parameter 'ensure'.
  Defaults to 'present'.

[*pipeline*]
  (optional) The list of elements of the container reconciler pipeline.
  Defaults to ['catch_errors', 'proxy-logging', 'cache', 'proxy-server']

[*interval*]
  (optional) Minimum time for a pass to take, in seconds.
  Defaults to $facts['os_service_default']

[*reclaim_age*]
  (optional) The reconciler will re-attempt reconciliation if the source
  object is not available up to reclaim_age seconds before it gives up and
  deletes the entry in the queue.
  Defaults to $facts['os_service_default']

[*request_tries*]
  (optional) Server errors from requests will be retried by default
  Defaults to $facts['os_service_default']

[*service_provider*]
  (optional)
  To use the swiftinit service provider to manage swift services, set
  service_provider to "swiftinit".  When enable is true the provider
  will populate boot files that start swift using swift-init at boot.
  See README for more details.
  Defaults to $::swift::params::service_provider.

[*memcache_servers*]
  (optional)
  A list of the memcache servers to be used. Entries should be in the
  form host:port. This value is only used if 'cache' is added to the
  pipeline,
  e.g. ['catch_errors', 'proxy-logging', 'cache', 'proxy-server']
  Defaults to ['127.0.0.1:11211']
cache_tls_enabled

(Optional) Global toggle for TLS usage when communicating with the caching servers. Default to false

cache_tls_cafile

(Optional) Path to a file of concatenated CA certificates in PEM format necessary to establish the caching server’s authenticity. If tls_enabled is False, this option is ignored. Defaults to $facts

cache_tls_certfile

(Optional) Path to a single file in PEM format containing the client’s certificate as well as any number of CA certificates needed to establish the certificate’s authenticity. This file is only required when client side authentication is necessary. If tls_enabled is False, this option is ignored. Defaults to $facts

cache_tls_keyfile

(Optional) Path to a single file containing the client’s private key in. Otherwise the private key will be taken from the file specified in tls_certfile. If tls_enabled is False, this option is ignored. Defaults to $facts
