After discussion in the Large Deployments Team session this morning, we wanted to follow up on the earlier thread [1,2] about overriding endpoint URLs.
That topic is exposing an underlying implication about the purpose of the service catalog. The LDT position is that the service catalog should be for end user clients to do endpoint discovery. While it can also be used for discovery by other OpenStack services, we desire to maintain the ability to override (like that which was discussed in the previous thread about Glance.) In addition to the Glance to nova-compute use case, the feedback during the LDT session surfaced potential use cases for other services. The point to raise here from LDT is that we would like to avoid a trend toward services *only* supporting discovery via the service catalog, with no ability to override in config. I.e., we want to maintain the endpoint_override (and similar) options. Thanks!
