Integrations
This page overviews integrations with other services like Neutron and others to make use of Designate more convenient.
Reverse - FloatingIP
The FloatingIP PTR feature of Designate relies on information of the FloatingIP which is in a different service than Designate itself. It can be in any service as long as their is a "plugin" for it that can be loaded via the configuration setting called "network_api".
- Controller, views and schemas in the V2 API
- RPC Client towards Central used by the API and Sink
- Logic in Central to make it convenient for setting, unsetting, listing and getting FloatingIP PTR records compared to the Records themselves which would be more work. (This is outlined in code docstrings for the specific methods.)
- Sink handlers for the various backend to help us be more consistent.
Record invalidation
Happens mainly happens via comparing a Tenant's FloatingIPs towards the list we have of Records which are of a certain plugin type and with the use of a Sink handler that listens for incoming events from the various services.
Configuring Neutron
Configuring the FloatingIP feature is really simple:
[network_api:neutron] # endpoints = RegionOne|http://localhost:9696 # endpoint_type = publicURL # timeout = 30 # admin_username = designate # admin_password = designate # admin_tenant_name = designate # auth_url = http://localhost:35357/v2.0 # insecure = False # auth_strategy = keystone # ca_certificates_file = /etc/path/to/ca.pem
Note that using admin_user, admin_password and admin_tenant_name is optional, if not present we'll piggyback on the context.auth_token passed in by the API.
Note
If "endpoints" is not configured and there's no service catalog is present in the context passed by the API to Central the request will fail in a NoEndpoint exception.
