Overview

Class: nova::metadata

Setup and configure the Nova metadata API endpoint for wsgi

Parameters

neutron_metadata_proxy_shared_secret

(optional) Shared secret to validate proxies Neutron metadata requests Defaults to undef

metadata_cache_expiration

(optional) This option is the time (in seconds) to cache metadata. Defaults to $::os_service_default

local_metadata_per_cell

(optional) Indicates that the nova-metadata API service has been deployed per-cell, so that we can have better performance and data isolation in a multi-cell deployment. Users should consider the use of this configuration depending on how neutron is setup. If networks span cells, you might need to run nova-metadata API service globally. If your networks are segmented along cell boundaries, then you can run nova-metadata API service per cell. When running nova-metadata API service per cell, you should also configure each Neutron metadata-agent to point to the corresponding nova-metadata API service. Defaults to $::os_service_default

dhcp_domain

(optional) domain to use for building the hostnames Defaults to $::os_service_default

DEPRECATED

[*enabled_apis*]
 (optional) A list of apis to enable
 Defaults to undef.
enable_proxy_headers_parsing

(optional) This determines if the HTTPProxyToWSGI middleware should parse the proxy headers or not.(boolean value) Defaults to undef.

max_request_body_size

(Optional) Set max request body size Defaults to undef.

Parameters:

  • neutron_metadata_proxy_shared_secret (Any) (defaults to: undef)
  • metadata_cache_expiration (Any) (defaults to: $::os_service_default)
  • local_metadata_per_cell (Any) (defaults to: $::os_service_default)
  • dhcp_domain (Any) (defaults to: $::os_service_default)
  • enabled_apis (Any) (defaults to: undef)
  • enable_proxy_headers_parsing (Any) (defaults to: undef)
  • max_request_body_size (Any) (defaults to: undef)
