Configuration Options

The following is an overview of all available configuration options in Masakari.

For a sample configuration file, refer to Masakari Configuration Options.

DEFAULT

auth_strategy
Type

string

Default

keystone

Valid Values

keystone, noauth2

This determines the strategy to use for authentication: keystone or noauth2. ‘noauth2’ is designed for testing only, as it does no actual credential checking. ‘noauth2’ provides administrative credentials only if ‘admin’ is specified as the username.

  • Possible values:

    Either ‘keystone’ (default) or ‘noauth2’.

  • Services that use this:

    masakari-api

  • Related options:

    None

use_forwarded_for
Type

boolean

Default

False

When True, the ‘X-Forwarded-For’ header is treated as the canonical remote address. When False (the default), the ‘remote_address’ header is used.

You should only enable this if you have an HTML sanitizing proxy.

  • Possible values:

    True, False (default)

  • Services that use this:

    masakari-api

  • Related options:

    None

osapi_max_limit
Type

integer

Default

1000

As a query can potentially return many thousands of items, you can limit the maximum number of items in a single response by setting this option.

  • Possible values:

    Any positive integer. Default is 1000.

  • Services that use this:

    masakari-api

  • Related options:

    None

Type

string

Default

<None>

This string is prepended to the normal URL that is returned in links to the OpenStack Masakari API. If it is empty (the default), the URLs are returned unchanged.

  • Possible values:

    Any string, including an empty string (the default).

  • Services that use this:

    masakari-api

  • Related options:

    None

tempdir
Type

string

Default

<None>

Explicitly specify the temporary working directory.

monkey_patch
Type

boolean

Default

False

Determine if monkey patching should be applied.

any effect

Type

string

Default

ha_engine

This is the message queue topic that the masakari engine ‘listens’ on. It is used when the masakari engine is started up to configure the queue, and whenever an RPC call to the masakari engine is made.

  • Possible values:

    Any string, but there is almost never any reason to ever change this value from its default of ‘engine’.

  • Services that use this:

    masakari-engine

  • Related options:

    None

Warning

This option is deprecated for removal since 3.0.0. Its value may be silently ignored in the future.

Reason

Configurable RPC topic provides little value and it can easily break Masakari if operator configures it to the same topic used by other OpenStack services.

Default

<None>

Complete “public” Identity API endpoint. This endpoint should not be an “admin” endpoint, as it should be accessible by all end users. Unauthenticated clients are redirected to this endpoint to authenticate. Although this endpoint should ideally be unversioned, client support in the wild varies. If you’re using a versioned v2 endpoint here, then this should not be the same endpoint the service user utilizes for validating tokens, because normal end users may not be able to reach that endpoint. This option is deprecated in favor of www_authenticate_uri and will be removed in the S release.

Warning

This option is deprecated for removal since Queens. Its value may be silently ignored in the future.

Reason

The auth_uri option is deprecated in favor of www_authenticate_uri and will be removed in the S release.

memcache_security_strategy
Type

string

Default

None

Valid Values

None, MAC, ENCRYPT

(Optional) If defined, indicate whether token data should be authenticated or authenticated and encrypted. If MAC, token data is authenticated (with HMAC) in the cache.

Used to control the use and type of token binding. Can be set to: “disabled” to not check token binding. “permissive” (default) to validate binding information if the bind type is of a form known to the server and ignore it if not. “strict” like “permissive” but if the bind type is unknown the token will be rejected. “required” any form of token binding is needed to be allowed. Finally the name of a binding method that must be present in tokens.

service_token_roles
Type

list

Default

['service']

A choice of roles that must be present in a service token. Service tokens are allowed to request that an expired token can be used and so this check should tightly control that only actual services should be sending this token. Roles here are applied as an ANY check so any role in this list must be present. For backwards compatibility reasons this currently only affects the allow_expired check.

service_token_roles_required
Type

boolean

Default

False

For backwards compatibility reasons we must let valid service tokens pass that don’t pass the service_token_roles check as valid. Setting this true will become the default in a future release and should be enabled if possible.

enforce_new_defaults
Type

boolean

Default

False

This option controls whether or not to use old deprecated defaults when evaluating policies. If True, the old deprecated defaults are not going to be evaluated. This means if any existing token is allowed for old defaults but is disallowed for new defaults, it will be disallowed. It is encouraged to enable this flag along with the enforce_scope flag so that you can get the benefits of new defaults and scope_type together. If False, the deprecated policy check string is logically OR’d with the new policy check string, allowing for a graceful upgrade experience between releases with new policies, which is the default behavior.
