OpenStack API Ports

I’m working with OpenStack APIs and noticed that the following endpoints use specific ports: Port 5000: - /auth/tokens?nocatalog - /auth/projects Port 8774: - /servers/detail - /flavors/detail - /images/detail - /os-hypervisors/detail I would like to know: Are these default port assignments (5000 for authentication and 8774 for compute services) configurable? Under what circumstances might these ports change? For example, would they differ in custom deployments or under certain OpenStack configurations?
