#build_service_catalog(compute_tenant, object_tenant) ⇒ Hash

Construct a full, fake service catalog.

Parameters:

  • compute_tenant (String)

    Tenant ID to be used in entries for compute-based services (most of them).

  • object_tenant (String)

    Tenant ID to be used in object-store related entries.

Returns:

  • (Hash)

    A fully-populated, valid service catalog.

#endpoint_entry(tenant_id, region, options) ⇒ Hash

Helper method that generates a single endpoint hash within a service catalog entry.

Parameters:

  • tenant_id (String)

    The tenant ID used for this endpoint.

  • region (String, nil)

    The region to include in this endpoint, if any.

  • options (Hash)

    Options inherited from #service_catalog_entry.

Returns:

  • (Hash)

    A well-formed endpoint hash.

#service_catalog_entry(name, type, tenant_id, options) ⇒ Hash

Generate an individual service catalog entry for a fake service catalog. Understands common patterns used within Rackspace service catalogs.

Parameters:

  • name (String)

    The required “name” attribute of the service catalog entry.

  • type (String)

    The required “type” attribute.

  • tenant_id (String)

    Tenant ID to be used for this service.

  • options (Hash)

    Control the contents of the generated entry.

Options Hash (options):

  • :public_url (Proc)

    Callable invoked with each region (or `nil`) to generate a `publicURL` for that region.

  • :single_endpoint (Boolean)

    If `true`, only a single endpoint entry will be generated, rather than an endpoint for each region.

  • :internal_url_snet (Boolean)

    If `true`, an internalURL entry will be generated by prepending “snet-” to the publicURL.

  • :rackspace_api_name (String)

    If specified, will generate publicURL as a Rackspace API URL.

  • :rackspace_api_version (String) — default: `"1.0"`

    Specify the version of the Rackspace API URL.

Returns:

  • (Hash)

    A valid service catalog entry.
