Service networking:
- ClusterIP IPAM allocation on service create/delete via reusable Ipam with_prefix()
- ServiceController watches Pod/Service events + periodic reconcile to track endpoints
- NatManager generates ipnat rdr rules for ClusterIP -> pod IP forwarding
- Embedded DNS server resolves {svc}.{ns}.svc.cluster.local to ClusterIP
- New CLI flags: --service-cidr (default 10.96.0.0/12), --cluster-dns (default 0.0.0.0:10053)
Quick wins:
- ipadm IP assignment: configure_zone_ip() runs ipadm/route inside zone via zlogin after boot
- Node heartbeat zone state reporting: reddwarf.io/zone-count and zone-summary annotations
- bhyve brand support: ZoneBrand::Bhyve, install args, zonecfg device generation, controller integration
189 tests passing, clippy clean.
