Externally Exposed Services

The following services are exposed on one or more of the external networks (CMN, CAN, and CHN). Each of these services requires an IP address in the relevant subnets so they are reachable on that network. This IP address is allocated by the MetalLB component.

Services under Istio Ingress Gateway and OAuth2 Proxy Ingress share an ingress, so they all use the IP allocated to the Ingress.

Each service is given a DNS name that is served by the PowerDNS service to make them resolvable from the site network. This makes it possible to access each of these services by name rather than finding the allocated IP address. The DNS name and network are prepended to the system-name.site-domain specified during csi config init. For example, if the system is named TestSystem, and the site is example.com, the HPE Cray EX domain would be testsystem.example.com.

See External DNS for more information.
